For a quarter-century, dating back to my time as a budding space enthusiast, I’ve watched with a keen eye each time people have ventured into space.

That’s 162 human spaceflight missions since the beginning of 2000, ranging from Space Shuttle flights to Russian Soyuz missions, Chinese astronauts’ first forays into orbit, and commercial expeditions on SpaceX’s Dragon capsule. Yes, I’m also counting privately funded suborbital hops launched by Blue Origin and Virgin Galactic.

Last week, Jeff Bezos’ Blue Origin captured headlines—though not purely positive—with the launch of six women, including pop star Katy Perry, to an altitude of 66 miles (106 kilometers). The capsule returned to the ground 10 minutes and 21 seconds later. It was the first all-female flight to space since Russian cosmonaut Valentina Tereshkova’s solo mission in 1963.

Many commentators criticized the flight as a tone-deaf stunt or a rich person’s flex. I won’t make any judgments, except to say two of the passengers aboard Blue Origin’s capsule—Aisha Bowe and Amanda Nguyen—have compelling stories worth telling.

Immerse yourself

Here’s another story worth sharing. Earlier this month, an international crew of four private astronauts took their own journey into space aboard a Dragon spacecraft owned and operated by Elon Musk’s SpaceX. Like Blue Origin’s all-female flight, this mission was largely bankrolled by a billionaire.

Actually, it was a couple of billionaires. Musk used his fortune to fund a large portion of the Dragon spacecraft’s development costs alongside a multibillion-dollar contribution from US taxpayers. Chun Wang, a Chinese-born cryptocurrency billionaire, paid SpaceX an undisclosed sum to fly one of SpaceX’s ships into orbit with three of his friends.

So far, this seems like another story about a rich guy going to space. This is indeed a major part of the story, but there’s more to it. Chun, now a citizen of Malta, named the mission Fram2 after the Norwegian exploration ship Fram used for polar expeditions at the turn of the 20th century. Following in the footsteps of Fram, which means “forward” in Norwegian, Chun asked SpaceX if he could launch into an orbit over Earth’s poles to gain a perspective on our planet no human eyes had seen before.

Joining Chun on the three-and-a-half-day Fram2 mission were Jannicke Mikkelsen, a Norwegian filmmaker and cinematographer who took the role of vehicle commander. Rabea Rogge, a robotics researcher from Germany, took the pilot’s seat and assisted Mikkelsen in monitoring the spacecraft’s condition in flight. Wang and Eric Philips, an Australian polar explorer and guide, flew as “mission specialists” on the mission.

Chun’s X account reads like a travelogue, with details of each jet-setting jaunt around the world. His propensity for sharing travel experiences extended into space, and I’m grateful for it.

Usually, astronauts might share their reflections from space by writing posts on social media, or occasionally sharing pictures and video vignettes from the International Space Station (ISS). This, in itself, is a remarkable change from the way astronauts communicated with the public from space just 15 years ago.

Most of these social media posts involve astronauts showcasing an experiment they’re working on or executing a high-flying tutorial in physics. Often, these videos include acrobatic backflips or show the novelty of eating and drinking in microgravity. Some astronauts, like Don Pettit, who recently came home from the ISS, have a knack for gorgeous orbital photography.

Chun’s videos offer something different. They provide an unfiltered look into how four people live inside a spacecraft with an internal volume comparable to an SUV, and the awe of seeing something beautiful for the first time. His shares have an intimacy, authenticity, and most importantly, an immediacy I’ve never seen before in a video from space.

One of the videos Chun recorded and posted to X shows the Fram2 crew members inside Dragon the day after their launch. The astronauts seem to be enjoying themselves. Their LunchBot meal kits float nearby, and the capsule’s makeshift trash bin contains Huggies baby wipes and empty water bottles, giving the environment a vibe akin to a camping trip, except for the constant hum of air fans.

Later, Chun shared a video of the crew opening the hatch leading to Dragon’s cupola window, a plexiglass extension with panoramic views. Mikkelsen and Chun try to make sense of what they’re seeing.

“Oh, Novaya Zemlya, do you see it?” Mikkelsen asks. “Yeah. Yeah. It’s right here,” Chun replies. “Oh, damn. Oh, it is,” Mikkelsen says.

Chun then drops a bit of Cold War trivia. “The largest atomic bomb was tested here,” he says. “And all this ice. Further north, the Arctic Ocean. The North Pole.”

On the third day of the mission, the Dragon spacecraft soared over Florida, heading south to north on its pole-to-pole loop around the Earth. “I can see our launch pad from here,” Mikkelsen says, pointing out NASA’s Kennedy Space Center several hundred miles away.

Finally, Chun capped his voyage into space with a 30-second clip from his seat inside Dragon as the spacecraft fires thrusters for a deorbit burn. The capsule’s small rocket jets pulsed repeatedly to slow Dragon’s velocity enough to drop out of orbit and head for reentry and splashdown off the coast of California.

Lasers in LEO

It wasn’t only Chun’s proclivity for posting to social media that made this possible. It was also SpaceX’s own Starlink Internet network, which the Dragon spacecraft connected to with a “Plug and Plaser” terminal mounted in the capsule’s trunk. This device allowed Dragon and its crew to transmit and receive Internet signals through a laser link with Starlink satellites orbiting nearby.

Astronauts have shared videos similar to those from Fram2 in the past, but almost always after they are back on Earth, and often edited and packaged into a longer video. What’s unique about Chun’s videos is that he was able to immediately post his clips, some of which are quite long, to social media via the Starlink Internet network.

“With a Starlink laser terminal in the trunk, we can theoretically achieve speeds up to 100 or more gigabits per second,” said Jon Edwards, SpaceX’s vice president for Falcon launch vehicles, before the Fram2 mission’s launch. “For Fram2, we’re expecting around 1 gigabit per second.”

Compare this with the connectivity available to astronauts on the International Space Station, where crews have access to the Internet with uplink speeds of about 4 to 6 megabits per second and 500 kilobits to 1 megabit per second of downlink, according to Sandra Jones, a NASA spokesperson. The space station communications system provides about 1 megabit per second of additional throughput for email, an Internet telephone, and video conferencing. There’s another layer of capacity for transmitting scientific and telemetry data between the space station and Mission Control.

So, Starlink’s laser connection with the Dragon spacecraft offers roughly 200 to 2,000 times the throughput of the Internet connection available on the ISS. The space station sends and receives communication signals, including the Internet, through NASA’s fleet of Tracking and Data Relay Satellites.

The laser link is also cheaper to use. NASA’s TDRS relay stations are dedicated to providing communication support for the ISS and numerous other science missions, including the Hubble Space Telescope, while Dragon plugs into the commercial Starlink network serving millions of other users.

SpaceX tested the Plug and Plaser device for the first time in space last year on the Polaris Dawn mission, which was most notable for the first fully commercial spacewalk in history. The results of the test were “phenomenal,” said Kevin Coggins, NASA’s deputy associate administrator for Space Communications and Navigation.

“They have pushed a lot of data through in these tests to demonstrate their ability to do data rates just as high as TDRS, if not higher,” Coggins said in a recent presentation to a committee of the National Academies.

Edwards said SpaceX wants to make the laser communication capability available for future Dragon missions and commercial space stations that may replace the ISS. Meanwhile, NASA is phasing out the government-owned TDRS network. Coggins said NASA’s relay satellites in geosynchronous orbit will remain active through the remaining life of the International Space Station, and then will be retired.

“Many of these spacecraft are far beyond their intended service life,” Coggins said. “In fact, we’ve retired one recently. We’re getting ready to retire another one. In this period of time, we’re going to retire TDRSs pretty often, and we’re going to get down to just a couple left that will last us into the 2030s.

“We have to preserve capacity as the constellation gets smaller, and we have to manage risks,” Coggins said. “So, we made a decision on November 8, 2024, that no new users could come to TDRS. We took it out of the service catalog.”

NASA’s future satellites in Earth orbit will send their data to the ground through a commercial network like Starlink. The agency has agreements worth more than $278 million with five companies—SpaceX, Amazon, Viasat, SES, and Telesat—to demonstrate how they can replace and improve on the services currently provided by TDRS (pronounced “tee-dress”).

These companies are already operating or will soon deploy satellites that could provide radio or laser optical communication links with future space stations, science probes, and climate and weather monitoring satellites. “We’re not paying anyone to put up a constellation,” Coggins said.

After these five companies complete their demonstration phase, NASA will become a subscriber to some or all of their networks.

“Now, instead of a 30-year-old [TDRS] constellation and trying to replenish something that we had before, we’ve got all these new capabilities, all these new things that weren’t possible before, especially optical,” Coggins said. “That’s going to that’s going to mean so much with the volume and quality of data that you’re going to be able to bring down.”

Digital nomads

Chun and his crewmates didn’t use the Starlink connection to send down any prize-winning discoveries about the Universe, or data for a comprehensive global mapping survey. Instead, the Fram2 crew used the connection for video calls and text messages with their families through tablets and smartphones linked to a Wi-Fi router inside the Dragon spacecraft.

“Are we the first generation of digital nomad in space?” Chun asked his followers in one X post.

“It was not 100 percent available, but when it was, it was really fast,” Chun wrote of the Internet connection in an email to Ars. He told us he used an iPhone 16 Pro Max for his 4K videos. From some 200 miles (300 kilometers) up, the phone’s 48-megapixel camera, with a simulated optical zoom, brought out the finer textures of ice sheets, clouds, water, and land formations.

While the flight was fully automated, SpaceX trained the Fram2 crew how to live and work inside the Dragon spacecraft and take over manual control if necessary. None of Fram2 crew members had a background in spaceflight or in any part of the space industry before they started preparing for their mission. Notably, it was the first human spaceflight mission to low-Earth orbit without a trained airplane pilot onboard.

Their nearly four days in orbit was largely a sightseeing expedition. Alongside Chun, Mikkelsen put her filmmaking expertise to use by shooting video from Dragon’s cupola. Before the flight, Mikkelsen said she wanted to create an immersive 3D account of her time in space. In some of Wang’s videos, Mikkelsen is seen working with a V-RAPTOR 8K VV camera from Red Digital Cinema, a device that sells for approximately $25,000, according to the manufacturer’s website.

The crew spent some of their time performing experiments, including the first X-ray of a human in space. Scientists gathered some useful data on the effects of radiation on humans in space because Fram2 flew in a polar orbit, where the astronauts were exposed to higher doses of ionizing radiation than a person might see on the International Space Station.

After they splashed down in the Pacific Ocean at the end of the mission, the Fram2 astronauts disembarked from the Dragon capsule without the assistance of SpaceX ground teams, which typically offer a helping hand for balance as crews readjust to gravity. This demonstrated how people might exit their spaceships on the Moon or Mars, where no one will be there to greet them.

Going into the flight, Chun wanted to see Antarctica and Svalbard, the Norwegian archipelago where he lives north of the Arctic Circle. In more than 400 human spaceflight missions from 1961 until this year, nobody ever flew in an orbit directly over the poles. Sophisticated satellites routinely fly over the polar regions to take high-resolution imagery and measure things like sea ice.

The Fram2 astronauts’ observations of the Arctic and Antarctic may not match what satellites can see, but their experience has some lasting catchet, standing alone among all who have flown to space before.

“People often refer to Earth as a blue marble planet, but from our point of view, it’s more of a frozen planet,” Chun told Ars.

Trump official to Katy Perry and Bezos’ fiancée: “You cannot identify as an astronaut”

astronaut, Space / Rejus Almole / April 19, 2025

Secretary of Transportation weighs in

That was pretty much how things stood until Thursday evening, when the Secretary of the US Department of Transportation, Sean Duffy, shared some thoughts on the social media site X.

“The last FAA guidelines under the Commercial Space Astronaut Wings Program were clear: Crewmembers who travel into space must have ‘demonstrated activities during flight that were essential to public safety, or contributed to human space flight safety,'” Duffy wrote. “The crew who flew to space this week on an automated flight by Blue Origin were brave and glam, but you cannot identify as an astronaut. They do not meet the FAA astronaut criteria.”

So there it was: The leading US official on transportation declaring that Perry et. al. were not astronauts. This is a pretty striking statement.

For starters the Federal Aviation Administration, an agency within the US Department of Transportation Duffy leads, has previously said it will take no part in determining whether people who fly on suborbital flights are astronauts. The agency makes this clear on its human spaceflight page, stating: “The FAA no longer designates anyone as an ‘astronaut.’ In addition, the FAA does not define where space begins.”

To step back just a little bit, the FAA created a commercial “Astronaut Wings” program back in 2004 to recognize the two pilots of SpaceShipOne, Mike Melvill and Brian Binnie, who flew the vehicle above 50 statute miles (80 km). After that time, the program recognized private citizens who flew on Virgin Galactic’s Unity spacecraft, Blue Origin’s New Shepard, and SpaceX’s orbital Crew Dragon vehicle. You flew, and you got astronaut wings.

Then, in December 2021, the agency stopped issuing wings. “With the advent of the commercial space tourism era, starting in 2022, the Federal Aviation Administration will now recognize individuals who reach space on its website instead of issuing Commercial Space Astronaut Wings,” the agency said. “Any individual who is on an FAA-licensed or permitted launch and reaches 50 statute miles above the surface of the Earth will be listed on the site.”

Welcome to Edition 7.40 of the Rocket Report! One of the biggest spaceflight questions in my mind right now is when Blue Origin’s New Glenn rocket will fly again. The company has been saying “late spring.” Today, the Aerospace Safety Advisory Panel said they were told June. Several officials have suggested to Ars that the next launch will, in reality, occur no earlier than October. So when will we see New Glenn again?

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Phantom Space delays Daytona launch, again. In a story that accepts what Phantom Space Founder Jim Cantrell says at face value, Payload Space reports that the company is “an up-and-coming launch provider and satellite manufacturer” and has “steadily built a three-pronged business model to take on the industry’s powerhouses.” It’s a surprisingly laudatory story for a company that has yet to accomplish much in space yet.

Putting the brakes on Daytona … What caught my eye is the section on the Daytona rocket, a small-lift vehicle the company is developing. “The company expects to begin flying Daytona late next year or early 2027, and already has a Daytona II and III in the works,” the publication reports. Why is this notable? Because in an article published less than two years ago, Cantrell said Phantom was hoping to launch an orbital test flight in 2024. In other words, the rocket is further from launch today than it was in 2023. I guess we’ll see what happens. (submitted by BH)

It appears the Minotaur IV rocket still exists. A Northrop Grumman Minotaur IV rocket successfully launched multiple classified payloads for the US National Reconnaissance Office on Wednesday, marking a return to Vandenberg Space Force Base for the solid-fueled launch vehicle after more than a decade, Space News reports. The mission, designated NROL-174, lifted off at 3: 33 p.m. Eastern from Space Launch Complex 8 at Vandenberg, California. The launch was successful.

Back on the California Coast … The Minotaur IV is a four-stage vehicle derived in part from decommissioned Peacekeeper intercontinental ballistic missiles. The first three stages are government-furnished Peacekeeper solid rocket motors, while the upper stage is a commercial Orion solid motor built by Northrop Grumman. NROL-174 follows previous NRO missions flown on Minotaur rockets—NROL-129 in 2020 and NROL-111 in 2021—both launched from NASA’s Wallops Flight Facility in Virginia. (submitted by EllPeaTea)

French launch firm gets some funding runway. The French government has awarded Latitude funding to support the construction of its new rocket factory in Reims, which is expected to open in 2026, European Spaceflight reports. Latitude first announced plans to develop a larger rocket factory in late 2023, when it expanded its original site from 1,500 to 3,000 square meters. The new facility is expected to span approximately 25,000 square meters and will support a production capacity of up to 50 Zephyr rockets per year.

Working toward a launch next year … The Zephyr rocket is designed to deliver payloads of up to 200 kilograms to low Earth orbit. It could make its debut in 2026 if all goes well. Latitude did not disclose the exact amount of funding it received for the construction of its new factory. However, it is known that while part of the funding will be awarded as a straight grant, a portion will take the form of a recoverable loan. (submitted by EllPeaTea)

RFA gets a new CEO. German launch vehicle startup Rocket Factory Augsburg has replaced its chief executive as it works toward a second chance for its first launch, Space News reports. Last Friday, RFA announced that Stefan Tweraser, who had been chief executive since October 2021, had been replaced by Indulis Kalnins.

Working toward a second launch attempt … The announcement did not give a reason for the change, but it suggested that the company was seeking someone with expertise in the aerospace industry to lead the company. Kalnins is on the aerospace faculty of a German university, Hochschule Bremen, and has been managing director of OHB Cosmos, which focused on launch services. RFA is working toward a second attempt at a first flight for RFA ONE later this year. (submitted by EllPeaTea)

Blue Origin launches all-female mission. Blue Origin’s 11th human flight—and first with an all-female flight team—blasted off from West Texas’ Launch Site One Monday morning on a flight that lasted about 10 minutes, Travel + Leisure reports. Katy Perry and Gayle King were joined by aerospace engineer Aisha Bowe, civil rights activist and scientist Amanda Nguyễn, film producer Kerianne Flynn, and Jeff Bezos’ fiancée Lauren Sánchez.

I kissed a Kármán line … “This experience has shown me you never know how much love is inside of you, how much love you have to give, and how loved you are, until the day you launch,” Perry said in her post-flight interview on the Blue Origin livestream, calling the experience “second only to being a mom” and rating it “10 out of 10.”

Bahamas to SpaceX: Let’s press pause. The Bahamas government said on Tuesday it is suspending all SpaceX Falcon 9 rocket landings in the country, pending a full post-launch investigation of the latest Starship mishap, Reuters reports. “No further clearances will be granted until a full environmental assessment is reviewed,” Bahamian Director of Communications Latrae Rahming said.

Falling from the sky … The Bahamian government said in February, after SpaceX’s first Falcon 9 first stage landing in the country, that it had approved 19 more throughout 2025, subject to regulatory approval. The Bahamas’ post-launch investigation comes after a SpaceX Starship spacecraft exploded in space last month, minutes after lifting off from Texas. Following the incident, the Bahamas said debris from the spacecraft fell into its airspace.

NASA will fly on Soyuz for a while longer. NASA and Roscosmos have extended a seat barter agreement for flights to the International Space Station into 2027 that will feature longer Soyuz missions to the station, Space News reports. Under the no-exchange-of-funds barter agreement, NASA astronauts fly on Soyuz spacecraft and Roscosmos cosmonauts fly on commercial crew vehicles to ensure that there is at least one American and one Russian on the station should either Soyuz or commercial crew vehicles be grounded for an extended period. “NASA and Roscosmos have amended the integrated crew agreement to allow for a second set of integrated crew missions in 2025, one set of integrated crew missions in 2026, and a SpaceX Dragon flight in 2027,” an agency spokesperson said.

Flying fewer times per year. One change with the agreement is the cadence of Soyuz missions. While Roscosmos had been flying Soyuz missions to the ISS every six months, missions starting with Soyuz MS-27 this April will spend eight months at the station. Neither NASA nor Roscosmos offered a reason for the change, which means that Roscosmos will fly one fewer Soyuz mission over a two-year period: three instead of four. I presume that this is a cost-saving measure. (submitted by EllPeaTea)

Falcon 9 sets reuse record. SpaceX notched another new rocket reuse record with its midnight Starlink flight on Sunday night from Florida, Spaceflight Now reports. The Falcon 9 rocket booster with the tail number 1067 launched for a record-setting 27th time, further cementing its position as the flight leader among SpaceX’s fleet.

Approaching 500 launches … It supported the launch of 27 Starlink V2 Mini satellites heading into low Earth orbit. The 27th outing for B1067 comes nearly four years after it launched its first mission, CRS-22 on June 3, 2021. Its three most recent missions were all in support of SpaceX’s Starlink satellite constellation. The Starlink 6-73 mission was also the 460th launch of a Falcon 9 rocket to date.

The real story behind the Space Shuttle legislation. Last week, two US senators from Texas, John Cornyn and Ted Cruz, filed the “Bring the Space Shuttle Home Act” to move Space Shuttle Discovery from its current location at the Smithsonian’s National Air and Space Museum’s Steven F. Udvar-Hazy Center in Virginia to Houston. After the senators announced their bill, the collective response from the space community was initially shock. This was soon followed by: why? Ars spoke with several people on background, both from the political and space spheres, to get a sense of what is really happening here.

Bill is not going anywhere … The short answer is that it is all political, and the timing is due to the reelection campaign for Cornyn, who faces a stiff runoff against Ken Paxton. The legislation is, in DC parlance, a “messaging bill.” Cornyn is behind this, and Cruz simply agreed to go along. The goal in Cornyn’s campaign is to use the bill as a way to show Texans that he is fighting for them in Washington, DC, against the evils there. Presumably, he will blame the Obama administration, even though it is quite clear in hindsight that there were no political machinations behind the decision to not award a space shuttle to Houston. Space Center Houston, which would be responsible for hosting the shuttle, was not even told about the legislation before it was filed.

There’s a secret reason the Space Force is delaying the next Atlas V launch

Amazon, kuiper, launch, Space, space force, united launch alliance / Kris Guyer / April 18, 2025

The Space Force is looking for responsive launch. This week, they’re the unresponsive ones.

Last week, the first operational satellites for Amazon’s Project Kuiper broadband network were minutes from launch at Cape Canaveral Space Force Station, Florida.

These spacecraft, buttoned up on top of a United Launch Alliance Atlas V rocket, are the first of more than 3,200 mass-produced satellites Amazon plans to launch over the rest of the decade to deploy the first direct US competitor to SpaceX’s Starlink internet network.

However, as is often the case on Florida’s Space Coast, bad weather prevented the satellites from launching April 9. No big deal, right? Anyone who pays close attention to the launch industry knows delays are part of the business. A broken component on the rocket, a summertime thunderstorm, or high winds can thwart a launch attempt. Launch companies know this, and the answer is usually to try again the next day.

But something unusual happened when ULA scrubbed the countdown last Wednesday. ULA’s launch director, Eric Richards, instructed his team to “proceed with preparations for an extended turnaround.” This meant ULA would have to wait more than 24 hours for the next Atlas V launch attempt.

But why?

At first, there seemed to be a good explanation for the extended turnaround. SpaceX was preparing to launch a set of Starlink satellites on a Falcon 9 rocket around the same time as Atlas V’s launch window the next day. The Space Force’s Eastern Range manages scheduling for all launches at Cape Canaveral and typically operates on a first-come, first-served basis.

The Space Force accommodated 93 launches on the Eastern Range last year—sometimes on the same day—an annual record that military officials are quite proud of achieving. This is nearly six times the number of launches from Cape Canaveral in 2014, a growth rate primarily driven by SpaceX. In previous interviews, Space Force officials have emphasized their eagerness to support more commercial launches. “How do we get to yes?” is often what range officials ask themselves when a launch provider submits a scheduling request.

It wouldn’t have been surprising for SpaceX to get priority on the range schedule since it had already reserved the launch window with the Space Force for April 10. SpaceX subsequently delayed this particular Starlink launch for two days until it finally launched on Saturday evening, April 12. Another SpaceX Starlink mission launched Monday morning.

There are several puzzling things about what happened last week. When SpaceX missed its reservation on the range twice in two days, April 10 and 11, why didn’t ULA move back to the front of the line?

ULA, which is usually fairly transparent about its reasons for launch scrubs, didn’t disclose any technical problems with the rocket that would have prevented another launch attempt. ULA offers access to listen to the launch team’s audio channel during the countdown, and engineers were not discussing any significant technical issues.

The company’s official statement after the scrub said: “A new launch date will be announced when approved on the range.”

Also, why can’t ULA make another run at launching the Kuiper mission this week? The answer to that question is also a mystery, but we have some educated speculation.

Changes in attitudes

A few days ago, SpaceX postponed one of its own Starlink missions from Cape Canaveral without explanation, leaving the Florida spaceport with a rare week without any launches. SpaceX plans to resume launches from Florida early next week with the liftoff of a resupply mission to the International Space Station. The delayed Starlink mission will fly a few days later.

Meanwhile, the next launch attempt for ULA is unknown.

Tory Bruno, ULA’s president and CEO, wrote on X that questions about what is holding up the next Atlas V launch are best directed toward the Space Force. A spokesperson for ULA told Ars the company is still working with the range to determine the next launch date. “The rocket and payload are healthy,” she said. “We will announce the new launch date once confirmed.”

While the SpaceX launch delay this week might suggest a link to the same range kerfuffle facing United Launch Alliance, it’s important to point out a key difference between the companies’ rockets. SpaceX’s Falcon 9 uses an automated flight termination system to self-destruct the rocket if it flies off course, while ULA’s Atlas V uses an older human-in-the-loop range safety system, which requires additional staff and equipment. Therefore, the Space Force is more likely to be able to accommodate a SpaceX mission near another activity on the range.

One more twist in this story is that a few days before the launch attempt, ULA changed its launch window for the Kuiper mission on April 9 from midday to the evening hours due to a request from the Eastern Range. Brig. Gen. Kristin Panzenhagen, the range commander, spoke with reporters in a roundtable meeting last week. After nearly 20 years of covering launches from Cape Canaveral, I found a seven-hour time change so close to launch to be unusual, so I asked Panzenhagen about the reason for it, mostly out of curiosity. She declined to offer any details.

“The Eastern Range is huge,” she said. “It’s 15 million square miles. So, as you can imagine, there are a lot of players that are using that range space, so there’s a lot of de-confliction … Public safety is our top priority, and we take that very seriously on both ranges. So, we are constantly de-conflicting, but I’m not going to get into details of what the actual conflict was.”

It turns out the range conflict now impacting the Eastern Range is having some longer-lasting impacts. While a one- or two-week launch delay doesn’t seem serious, it adds up to deferred or denied revenue for a commercial satellite operator. National security missions get priority on range schedules at Cape Canaveral and at Vandenberg Space Force Base in California, but there are significantly more commercial missions than military launches from both spaceports.

Clearly, there’s something out of the ordinary going on in the Eastern Range, which extends over much of the Atlantic Ocean to the southeast, east, and northeast of Cape Canaveral. The range includes tracking equipment, security forces, and ground stations in Florida and downrange sites in Bermuda and Ascension Island.

One possibility is a test of one or more submarine-launched Trident ballistic missiles, which commonly occur in the waters off the east coast of Florida. But those launches are usually accompanied by airspace and maritime warning notices to ensure pilots and sailors steer clear of the test. Nothing of the sort has been publicly released in the last couple of weeks.

Maybe something is broken at the Florida launch base. When launches were less routine than today, the range at Cape Canaveral would close for a couple of weeks per year for upgrades and refurbishment of critical infrastructure. This is no longer the case. In 2023, Panzenhagen told Ars that the Space Force changed the policy.

“When the Eastern Range was supporting 15 to 20 launches a year, we had room to schedule dedicated periods for maintenance of critical infrastructure,” she said at the time. “During these periods, launches were paused while teams worked the upgrades. Now that the launch cadence has grown to nearly twice per week, we’ve adapted to the new way of business to best support our mission partners.”

Perhaps, then, it’s something more secret, like a larger-scale, multi-element military exercise or war game that either requires Eastern Range participation or is taking place in areas the Space Force needs to clear for safety reasons for a rocket launch to go forward. The military sometimes doesn’t publicize these activities until they’re over.

A Space Force spokesperson did not respond to Ars Technica’s questions on the matter.

While we’re still a ways off from rocket launches becoming as routine as an airplane flight, the military is shifting in the way it thinks about spaceports. Instead of offering one-off bespoke services tailored to the circumstances of each launch, the Space Force wants to operate the ranges more like an airport.

“We’ve changed the nomenclature from calling ourselves a range to calling ourselves a spaceport because we see ourselves more like an airport in the future,” one Space Force official told Ars for a previous story.

In the National Defense Authorization Act for fiscal year 2024, Congress gave the Space Force the authority to charge commercial launch providers indirect fees to help pay for common infrastructure at Cape Canaveral and Vandenberg—things like roads, electrical and water utilities, and base security used by all rocket operators at each spaceport. The military previously could only charge rocket companies direct fees for the specific services it offered in support of a particular launch, while the government was on the hook for overhead costs.

Military officials characterize the change in law as a win-win for the government and commercial launch providers. Ideally, it will grow the pool of money available to modernize the military’s spaceports, making them more responsive to all users, whether it’s the Space Force, SpaceX, ULA, or a startup new to the launch industry.

Whatever is going on in Florida or the Atlantic Ocean this week, it’s something the Space Force doesn’t want to talk about in detail. Maybe there are good reasons for that.

Cape Canaveral is America’s busiest launch base. Extending the spaceport-airport analogy a little further, the closure of America’s busiest airport for a week or more would be a big deal. One of the holy grails the Space Force is pursuing is the capability to launch on demand.

This week, there’s demand for launch slots at Cape Canaveral, but the answer is no.

Why are two Texas senators trying to wrest a Space Shuttle from the Smithsonian?

Space, space center houston, Space Shuttle Discovery / Rejus Almole / April 17, 2025

Should the city of Houston, which proudly bills itself as “Space City,” have a prized Space Shuttle orbiter on public display?

More than a decade ago, arguably, the answer was yes. After all, the Space Shuttle program was managed from Johnson Space Center, in southeastern Houston. All the astronauts who flew on the shuttle trained there. And the vehicle was operated out of Mission Control at the Houston-based facility.

But when the final decisions were being made to distribute the shuttles 15 years ago, the Houston community dragged its feet on putting together a competitive proposal. There were also questions about the ability of Space Center Houston to raise funding to house the shuttle within a new display area, which magnified concerns that the historical vehicle, like a Saturn V rocket before it, would be left outside in the region’s humid environment. Finally, other cities offered better proposals for displaying the shuttles to the public.

In the end, the four shuttles were sent to museums in Washington, DC, New York, Florida, and California.

Bring it back home

And that was all more or less settled until last week when the two US senators from Texas, John Cornyn and Ted Cruz, filed the “Bring the Space Shuttle Home Act” to move Space Shuttle Discovery from its current location the Smithsonian’s National Air and Space Museum’s Steven F. Udvar-Hazy Center in Virginia to Houston.

The space collectibles news site, CollectSpace, has a good overview of why this move is stupidly impractical. Essentially, it would easily cost $1 billion to get one of the two shuttle aircraft carriers back into service and move Discovery, it is unclear where the shuttle could survive such a journey in its current state, and the Smithsonian is the nation’s premier museum. There’s a reason that Discovery, the most historical of the three remaining shuttles that have gone to space, was placed there.

After the senators announced their bill, the collective response from the space community was initially shock. This was soon followed by: why? And so I’ve spoken with several people on background, both from the political and space spheres, to get a sense of what is really happening here. The short answer is that it is all political, and the timing is due to the reelection campaign for Cornyn, who faces a stiff runoff against Ken Paxton.

Here’s how a satellite ended up as a ghostly apparition on Google Earth

airbus, Earth, france, Google, google maps, pleiades, Science, Space, spacex, starlink / Tim Belzer / April 16, 2025

Regardless of the identity of the satellite, this image is remarkable for several reasons.

First, despite so many satellites flying in space, it’s still rare to see a real picture—not just an artist’s illustration—of what one actually looks like in orbit. For example, SpaceX has released photos of Starlink satellites in launch configuration, where dozens of the spacecraft are stacked together to fit inside the payload compartment of the Falcon 9 rocket. But there are fewer well-resolved views of a satellite in its operational environment, with solar arrays extended like the wings of a bird.

This is changing as commercial companies place more and more imaging satellites in orbit. Several companies provide “non-Earth imaging” services by repurposing Earth observation cameras to view other objects in space. These views can reveal information that can be useful in military or corporate espionage.

Secondly, the Google Earth capture offers a tangible depiction of a satellite’s speed. An object in low-Earth orbit must travel at more than 17,000 mph (more than 27,000 km per hour) to keep from falling back into the atmosphere.

While the B-2’s motion caused it to appear a little smeared in the Google Earth image a few years ago, the satellite’s velocity created a different artifact. The satellite appears five times in different colors, which tells us something about how the image was made. Airbus’ Pleiades satellites take pictures in multiple spectral bands: blue, green, red, panchromatic, and near-infrared.

At lower left, the black outline of the satellite is the near-infrared capture. Moving up, you can see the satellite in red, blue, and green, followed by the panchromatic, or black-and-white, snapshot with the sharpest resolution. Typically, the Pleiades satellites record these images a split-second apart and combine the colors to generate an accurate representation of what the human eye might see. But this doesn’t work so well for a target moving at nearly 5 miles per second.

Should we settle Mars, or is it a dumb idea for humans to live off world?

Debate, Mars, settlement, Space / Mike M. / April 15, 2025

Mars is back on the agenda.

During his address to a joint session of Congress in March, President Donald Trump said the United States “will pursue our Manifest Destiny into the stars, launching American astronauts to plant the Stars and Stripes on the planet Mars.”

What does this mean? Manifest destiny is the belief, which was particularly widespread in 1800s America, that US settlers were destined to expand westward across North America. Similarly, then, the Trump administration believes it is the manifest destiny of Americans to settle Mars. And he wants his administration to take steps toward accomplishing that goal.

Should the US Prioritize Settling Mars?

But should we really do this?

I recently participated in a debate with Shannon Stirone, a distinguished science writer, on this topic. The debate was sponsored by Open to Debate, and professionally moderated by Emmy award-winning journalist John Donvan. Spoiler alert: I argued in favor of settlement. I hope you learned as much as I did.

Lunar Gateway’s skeleton is complete—its next stop may be Trump’s chopping block

Science, Space / Rejus Almole / April 15, 2025

Officials blame changing requirements for much of the delays and rising costs. NASA managers dramatically changed their plans for the Gateway program in 2020, when they decided to launch the PPE and HALO on the same rocket, prompting major changes to their designs.

Jared Isaacman, Trump’s nominee for NASA administrator, declined to commit to the Gateway program during a confirmation hearing before the Senate Commerce Committee on April 9. Sen. Ted Cruz (R-Texas), the committee’s chairman, pressed Isaacman on the Lunar Gateway. Cruz is one of the Gateway program’s biggest backers in Congress since it is managed by Johnson Space Center in Texas. If it goes ahead, Gateway would guarantee numerous jobs at NASA’s mission control in Houston throughout its 15-year lifetime.

“That’s an area that if I’m confirmed, I would love to roll up my sleeves and further understand what’s working right?” Isaacman replied to Cruz. “What are the opportunities the Gateway presents to us? And where are some of the challenges, because I think the Gateway is a component of many programs that are over budget and behind schedule.”

Checking in with Gateway

Nevertheless, the Gateway program achieved a milestone one week before Isaacman’s confirmation hearing. The metallic pressure shell for the HALO module was shipped from its factory in Italy to Arizona. The HALO module is only partially complete, and it lacks life support systems and other hardware it needs to operate in space.

Over the next couple of years, Northrop Grumman will outfit the habitat with those components and connect it with the Power and Propulsion Element under construction at Maxar Technologies in Silicon Valley. This stage of spacecraft assembly, along with prelaunch testing, often uncovers problems that can drive up costs and trigger more delays.

Ars recently spoke with Jon Olansen, a bio-mechanical engineer and veteran space shuttle flight controller who now manages the Gateway program at Johnson Space Center. A transcript of our conversation with Olansen is below. It is lightly edited for clarity and brevity.

Ars: The HALO module has arrived in Arizona from Italy. What’s next?

Olansen: This HALO module went through significant effort from the primary and secondary structure perspective out at Thales Alenia Space in Italy. That was most of their focus in getting the vehicle ready to ship to Arizona. Now that it’s in Arizona, Northrop is setting it up in their facility there in Gilbert to be able to do all of the outfitting of the systems we need to actually execute the missions we want to do, keep the crew safe, and enable the science that we’re looking to do. So, if you consider your standard spacecraft, you’re going to have all of your command-and-control capabilities, your avionics systems, your computers, your network management, all of the things you need to control the vehicle. You’re going to have your power distribution capabilities. HALO attaches to the Power and Propulsion Element, and it provides the primary power distribution capability for the entire station. So that’ll all be part of HALO. You’ll have your standard thermal systems for active cooling. You’ll have the vehicle environmental control systems that will need to be installed, [along with] some of the other crew systems that you can think of, from lighting, restraint, mobility aids, all the different types of crew systems. Then, of course, all of our science aspects. So we have payload lockers, both internally, as well as payload sites external that we’ll have available, so pretty much all the different systems that you would need for a human-rated spacecraft.

Ars: What’s the latest status of the Power and Propulsion Element?

Olansen: PPE is fairly well along in their assembly and integration activities. The central cylinder has been integrated with the propulsion tanks… Their propulsion module is in good shape. They’re working on the avionics shelves associated with that spacecraft. So, with both vehicles, we’re really trying to get the assembly done in the next year or so, so we can get into integrated spacecraft testing at that point in time.

Ars: What’s in the critical path in getting to the launch pad?

Olansen: The assembly and integration activity is really the key for us. It’s to get to the full vehicle level test. All the different activities that we’re working on across the vehicles are making substantive progress. So, it’s a matter of bringing them all in and doing the assembly and integration in the appropriate sequences, so that we get the vehicles put together the way we need them and get to the point where we can actually power up the vehicles and do all the testing we need to do. Obviously, software is a key part of that development activity, once we power on the vehicles, making sure we can do all the control work that we need to do for those vehicles.

[There are] a couple of key pieces I will mention along those lines. On the PPE side, we have the electrical propulsion system. The thrusters associated with that system are being delivered. Those will go through acceptance testing at the Glenn Research Center [in Ohio] and then be integrated on the spacecraft out at Maxar; so that work is ongoing as we speak. Out at ESA, ESA is providing the HALO lunar communication system. That’ll be delivered later this year. That’ll be installed on HALO as part of its integrated test and checkout and then launch on HALO. That provides the full communication capability down to the lunar surface for us, where PPE provides the communication capability back to Earth. So, those are key components that we’re looking to get delivered later this year.

Ars: What’s the status of the electric propulsion thrusters for the PPE?

Olansen: The first one has actually been delivered already, so we’ll have the opportunity to go through, like I said, the acceptance testing for those. The other flight units are right on the heels of the first one that was delivered. They’ll make it through their acceptance testing, then get delivered to Maxar, like I said, for integration into PPE. So, that work is already in progress. [The Power and Propulsion Element will have three xenon-fueled 12-kilowatt Hall thrusters produced by Aerojet Rocketdyne, and four smaller 6-kilowatt thrusters.]

Ars: The Government Accountability Office (GAO) outlined concerns last year about keeping the mass of Gateway within the capability of its rocket. Has there been any progress on that issue? Will you need to remove components from the HALO module and launch them on a future mission? Will you narrow your launch windows to only launch on the most fuel-efficient trajectories?

Olansen: We’re working the plan. Now that we’re launching the two vehicles together, we’re working mass management. Mass management is always an issue with spacecraft development, so it’s no different for us. All of the things you described are all knobs that are in the trade space as we proceed, but fundamentally, we’re working to design the optimal spacecraft that we can, first. So, that’s the key part. As we get all the components delivered, we can measure mass across all of those components, understand what our integrated mass looks like, and we have several different options to make sure that we’re able to execute the mission we need to execute. All of those will be balanced over time based on the impacts that are there. There’s not a need for a lot of those decisions to happen today. Those that are needed from a design perspective, we’ve already made. Those that are needed from enabling future decisions, we’ve already made all of those. So, really, what we’re working through is being able to, at the appropriate time, make decisions necessary to fly the vehicle the way we need to, to get out to NRHO [Near Rectilinear Halo Orbit, an elliptical orbit around the Moon], and then be able to execute the Artemis missions in the future.

Ars: The GAO also discussed a problem with Gateway’s controllability with something as massive as Starship docked to it. What’s the latest status of that problem?

Olansen: There are a number of different risks that we work through as a program, as you’d expect. We continue to look at all possibilities and work through them with due diligence. That’s our job, to be able to do that on a daily basis. With the stack controllability [issue], where that came from for GAO, we were early in the assessments of what the potential impacts could be from visiting vehicles, not just any one [vehicle] but any visiting vehicle. We’re a smaller space station than ISS, so making sure we understand the implications of thruster firings as vehicles approach the station, and the implications associated with those, is where that stack controllability conversation came from.

The bus that Maxar typically designs doesn’t have to generally deal with docking. Part of what we’ve been doing is working through ways that we can use the capabilities that are already built into that spacecraft differently to provide us the control authority we need when we have visiting vehicles, as well as working with the visiting vehicles and their design to make sure that they’re minimizing the impact on the station. So, the combination of those two has largely, over the past year since that report came out, improved where we are from a stack controllability perspective. We still have forward work to close out all of the different potential cases that are there. We’ll continue to work through those. That’s standard forward work, but we’ve been able to make some updates, some software updates, some management updates, and logic updates that really allow us to control the stack effectively and have the right amount of control authority for the dockings and undockings that we will need to execute for the missions.

Trump White House budget proposal eviscerates science funding at NASA

NASA, Science, Space / Paul Patrick / April 13, 2025

This week, as part of the process to develop a budget for fiscal-year 2026, the Trump White House shared the draft version of its budget request for NASA with the space agency.

This initial version of the administration’s budget request calls for an approximately 20 percent overall cut to the agency’s budget across the board, effectively $5 billion from an overall topline of about $25 billion. However, the majority of the cuts are concentrated within the agency’s Science Mission Directorate, which oversees all planetary science, Earth science, astrophysics research, and more.

According to the “passback” documents given to NASA officials on Thursday, the space agency’s science programs would receive nearly a 50 percent cut in funding. After the agency received $7.5 billion for science in fiscal-year 2025, the Trump administration has proposed a science topline budget of just $3.9 billion for the coming fiscal year.

Detailing the cuts

Among the proposals were: A two-thirds cut to astrophysics, down to $487 million; a greater than two-thirds cut to heliophysics, down to $455 million; a greater than 50 percent cut to Earth science, down to $1.033 billion; and a 30 percent cut to Planetary science, down to $1.929 billion.

Although the budget would continue support for ongoing missions such as the Hubble Space Telescope and the James Webb Space Telescope, it would kill the much-anticipated Nancy Grace Roman Space Telescope, an observatory seen as on par with those two world-class instruments that is already fully assembled and on budget for a launch in two years.

“Passback supports continued operation of the Hubble and James Webb Space Telescopes and assumes no funding is provided for other telescopes,” the document states.

“What the hell are you doing?” How I learned to interview astronauts, scientists, and billionaires

butch wilmore, elon musk, Features, Interviews, scott kelly, Space / Tim Belzer / April 13, 2025

The best part about journalism is not collecting information. It’s sharing it.

Sometimes the best place to do an interview is in a clean room. Credit: Lee Hutchinson

I recently wrote a story about the wild ride of the Starliner spacecraft to the International Space Station last summer. It was based largely on an interview with the commander of the mission, NASA astronaut Butch Wilmore.

His account of Starliner’s thruster failures—and his desperate efforts to keep the vehicle flying on course—was riveting. In the aftermath of the story, many readers, people on social media, and real-life friends congratulated me on conducting a great interview. But truth be told, it was pretty much all Wilmore.

Essentially, when I came into the room, he was primed to talk. I’m not sure if Wilmore was waiting for me specifically to talk to, but he pretty clearly wanted to speak with someone about his experiences aboard the Starliner spacecraft. And he chose me.

So was it luck? I’ve been thinking about that. As an interviewer, I certainly don’t have the emotive power of some of the great television interviewers, who are masters of confrontation and drama. It’s my nature to avoid confrontation where possible. But what I do have on my side is experience, more than 25 years now, as well as preparation. I am also genuinely and completely interested in space. And as it happens, these values are important, too.

Interviewing is a craft one does not pick up overnight. During my career, I have had some funny, instructive, and embarrassing moments. Without wanting to seem pretentious or self-indulgent, I thought it might be fun to share some of those stories so you can really understand what it’s like on a reporter’s side of the cassette tape.

March 2003: Stephen Hawking

I had only been working professionally as a reporter at the Houston Chronicle for a few years (and as the newspaper’s science writer for less time still) when the opportunity to interview Stephen Hawking fell into my lap.

What a coup! He was only the world’s most famous living scientist, and he was visiting Texas at the invitation of a local billionaire named George Mitchell. A wildcatter and oilman, Mitchell had grown up in Galveston along the upper Texas coast, marveling at the stars as a kid. He studied petroleum engineering and later developed the controversial practice of fracking. In his later years, Mitchell spent some of his largesse on the pursuits of his youth, including astronomy and astrophysics. This included bringing Hawking to Texas more than half a dozen times in the 1990s and early 2000s.

For an interview with Hawking, one submitted questions in advance. That’s because Hawking was afflicted with Lou Gehrig’s disease and lost the ability to speak in 1985. A computer attached to his wheelchair cycled through letters and sounds, and Hawking clicked a button to make a selection, forming words and then sentences, which were sent to a voice synthesizer. For unprepared responses, it took a few minutes to form a single sentence.

What to ask him? I had a decent understanding of astronomy, having majored in it as an undergraduate. But the readership of a metro newspaper was not interested in the Hubble constant or the Schwarzschild radius. I asked him about recent discoveries of the cosmic microwave background radiation anyway. Perhaps the most enduring response was about the war in Iraq, a prominent topic of the day. “It will be far more difficult to get out of Iraq than to get in,” he said. He was right.

When I met him at Texas A&M University, Hawking was gracious and polite. He answered a couple of questions in person. But truly, it was awkward. Hawking’s time on Earth was limited and his health failing, so it required an age to tap out even short answers. I can only imagine his frustration at the task of communication, which the vast majority of humans take for granted, especially because he had such a brilliant mind and so many deep ideas to share. And here I was, with my banal questions, stealing his time. As I stood there, I wondered whether I should stare at him while he composed a response. Should I look away? I felt truly unworthy.

In the end, it was fine. I even met Hawking a few more times, including at a memorable dinner at Mitchell’s ranch north of Houston, which spans tens of thousands of acres. A handful of the world’s most brilliant theoretical physicists were there. We would all be sitting around chatting, and Hawking would periodically chime in with a response to something brought up earlier. Later on that evening, Mitchell and Hawking took a chariot ride around the grounds. I wonder what they talked about?

Spring 2011: Jane Goodall and Sylvia Earle

By this point, I had written about science for nearly a decade at the Chronicle. In the early part of the year, I had the opportunity to interview noted chimpanzee scientist Jane Goodall and one of the world’s leading oceanographers, Sylvia Earle. Both were coming to Houston to talk about their research and their passion for conservation.

I spoke with Goodall by phone in advance of her visit, and she was so pleasant, so regal. By then, Goodall was 76 years old and had been studying chimpanzees in Gombe Stream National Park in Tanzania for five decades. Looking back over the questions I asked, they’re not bad. They’re just pretty basic. She gave great answers regardless. But there is only so much chemistry you can build with a person over the telephone (or Zoom, for that matter, these days). Being in person really matters in interviewing because you can read cues, and it’s easier to know when to let a pause go. The comfort level is higher. When you’re speaking with someone you don’t know that well, establishing a basic level of comfort is essential to making an all-important connection.

A couple of months later, I spoke with Earle in person at the Houston Museum of Natural Science. I took my older daughter, then nine years old, because I wanted her to hear Earle speak later in the evening. This turned out to be a lucky move for a couple of different reasons. First, my kid was inspired by Earle to pursue studies in marine biology. And more immediately, the presence of a curious 9-year-old quickly warmed Earle to the interview. We had a great discussion about many things beyond just oceanography.

The bottom line is that I remained a fairly pedestrian interviewer back in 2011. That was partly because I did not have deep expertise in chimpanzees or oceanography. And that leads me to another key for a good interview and establishing a rapport. It’s great if a person already knows you, but even if they don’t, you can overcome that by showing genuine interest or demonstrating your deep knowledge about a subject. I would come to learn this as I started to cover space more exclusively and got to know the industry and its key players better.

September 2014: Scott Kelly

To be clear, this was not much of an interview. But it is a fun story.

I spent much of 2014 focused on space for the Houston Chronicle. I pitched the idea of an in-depth series on the sorry state of NASA’s human spaceflight program, which was eventually titled “Adrift.” By immersing myself in spaceflight for months on end, I discovered a passion for the topic and knew that writing about space was what I wanted to do for the rest of my life. I was 40 years old, so it was high time I found my calling.

As part of the series, I traveled to Kazakhstan with a photographer from the Chronicle, Smiley Pool. He is a wonderful guy who had strengths in chatting up sources that I, an introvert, lacked. During the 13-day trip to Russia and Kazakhstan, we traveled with a reporter from Esquire named Chris Jones, who was working on a long project about NASA astronaut Scott Kelly. Kelly was then training for a yearlong mission to the International Space Station, and he was a big deal.

Jones was a tremendous raconteur and an even better writer—his words, my goodness. We had so much fun over those two weeks, sharing beer, vodka, and Kazakh food. The capstone of the trip was seeing the Soyuz TMA-14M mission launch from the Baikonur Cosmodrome. Kelly was NASA’s backup astronaut for the flight, so he was in quarantine alongside the mission’s primary astronaut. (This was Butch Wilmore, as it turns out). The launch, from a little more than a kilometer away, was still the most spectacular moment of spaceflight I’ve ever observed in person. Like, holy hell, the rocket was right on top of you.

Immediately after the launch, which took place at 1: 25 am local time, Kelly was freed from quarantine. This must have been liberating because he headed straight to the bar at the Hotel Baikonur, the nicest watering hole in the small, Soviet-era town. Jones, Pool, and I were staying at a different hotel. Jones got a text from Kelly inviting us to meet him at the bar. Our NASA minders were uncomfortable with this, as the last thing they want is to have astronauts presented to the world as anything but sharp, sober-minded people who represent the best of the best. But this was too good to resist.

By the time we got to the bar, Kelly and his companion, the commander of his forthcoming Soyuz flight, Gennady Padalka, were several whiskeys deep. The three of us sat across from Kelly and Padalka, and as one does at 3 am in Baikonur, we started taking shots. The astronauts were swapping stories and talking out of school. At one point, Jones took out his notebook and said that he had a couple of questions. To this, Kelly responded heatedly, “What the hell are you doing?”

Not conducting an interview, apparently. We were off the record. Well, until today at least.

We drank and talked for another hour or so, and it was incredibly memorable. At the time, Kelly was probably the most famous active US astronaut, and here I was throwing down whiskey with him shortly after watching a rocket lift off from the very spot where the Soviets launched the Space Age six decades earlier. In retrospect, this offered a good lesson that the best interviews are often not, in fact, interviews. To get the good information, you need to develop relationships with people, and you do that by talking with them person to person, without a microphone, often with alcohol.

Scott Kelly is a real one for that night.

September 2019: Elon Musk

I have spoken with Elon Musk a number of times over the years, but none was nearly so memorable as a long interview we did for my first book on SpaceX, called Liftoff. That summer, I made a couple of visits to SpaceX’s headquarters in Hawthorne, California, interviewing the company’s early employees and sitting in on meetings in Musk’s conference room with various teams. Because SpaceX is such a closed-up company, it was fascinating to get an inside look at how the sausage was made.

It’s worth noting that this all went down a few months before the onset of the COVID-19 pandemic. In some ways, Musk is the same person he was before the outbreak. But in other ways, he is profoundly different, his actions and words far more political and polemical.

Anyway, I was supposed to interview Musk on a Friday evening at the factory at the end of one of these trips. As usual, Musk was late. Eventually, his assistant texted, saying something had come up. She was desperately sorry, but we would have to do the interview later. I returned to my hotel, downbeat. I had an early flight the next morning back to Houston. But after about an hour, the assistant messaged me again. Musk had to travel to South Texas to get the Starship program moving. Did I want to travel with him and do the interview on the plane?

As I sat on his private jet the next day, late morning, my mind swirled. There would be no one else on the plane but Musk, his three sons (triplets, then 13 years old) and two bodyguards, and me. When Musk is in a good mood, an interview can be a delight. He is funny, sharp, and a good storyteller. When Musk is in a bad mood, well, an interview is usually counterproductive. So I fretted. What if Musk was in a bad mood? It would be a super-awkward three and a half hours on the small jet.

Two Teslas drove up to the plane, the first with Musk driving his boys and the second with two security guys. Musk strode onto the jet, saw me, and said he didn’t realize I was going to be on the plane. (A great start to things!) Musk then took out his phone and started a heated conversation about digging tunnels. By this point, I was willing myself to disappear. I just wanted to melt into the leather seat I was sitting in about three feet from Musk.

So much for a good mood for the interview.

As the jet climbed, the phone conversation got worse, but then Musk lost his connection. He put away his phone and turned to me, saying he was free to talk. His mood, almost as if by magic, changed. Since we were discussing the early days of SpaceX at Kwajalein, he gathered the boys around so they could hear about their dad’s earlier days. The interview went shockingly well, and at least part of the reason has to be that I knew the subject matter deeply, had prepared, and was passionate about it. We spoke for nearly two hours before Musk asked if he might have some time with his kids. They spent the rest of the flight playing video games, yucking it up.

April 2025: Butch Wilmore

When they’re on the record, astronauts mostly stick to a script. As a reporter, you’re just not going to get too much from them. (Off the record is a completely different story, of course, as astronauts are generally delightful, hilarious, and earnest people.)

Last week, dozens of journalists were allotted 10-minute interviews with Wilmore and, separately, Suni Williams. It was the first time they had spoken in depth with the media since their launch on Starliner and return to Earth aboard a Crew Dragon vehicle. As I waited outside Studio A at Johnson Space Center, I overheard Wilmore completing an interview with a Tennessee-based outlet, where he is from. As they wrapped up, the public affairs officer said he had just one more interview left and said my name. Wilmore said something like, “Oh good, I’ve been waiting to talk with him.”

That was a good sign. Out of all the interviews that day, it was good to know he wanted to speak with me. The easy thing for him to do would have been to use “astronaut speak” for 10 minutes and then go home. I was the last interview of the day.

As I prepared to speak with Wilmore and Williams, I didn’t want to ask the obvious questions they’d answered many times earlier. If you ask, “What was it like to spend nine months in space when you were expecting only a short trip?” you’re going to get a boring answer. Similarly, although the end of the mission was highly politicized by the Trump White House, two veteran NASA astronauts were not going to step on that landmine.

I wanted to go back to the root cause of all this, the problems with Starliner’s propulsion system. My strategy was simply to ask what it was like to fly inside the spacecraft. Williams gave me some solid answers. But Wilmore had actually been at the controls. And he apparently had been holding in one heck of a story for nine months. Because when I asked about the launch, and then what it was like to fly Starliner, he took off without much prompting.

I don’t know exactly why Wilmore shared so much with me. We are not particularly close and have never interacted outside of an official NASA setting. But he knows of my work and interest in spaceflight. Not everyone at the space agency appreciates my journalism, but they know I’m deeply interested in what they’re doing. They know I care about NASA and Johnson Space Center. So I asked Wilmore a few smart questions, and he must have trusted that I would tell his story honestly and accurately, and with appropriate context. I certainly tried my best. After a quarter of a century, I have learned well that the most sensational stories are best told without sensationalism.

Even as we spoke, I knew the interview with Wilmore was one of the best I had ever done. A great scientist once told me that the best feeling in the world is making some little discovery in a lab and for a short time knowing something about the natural world that no one else knows. The equivalent, for me, is doing an interview and knowing I’ve got gold. And for a little while, before sharing it with the world, I’ve got that little piece of gold all to myself.

But I’ll tell you what. It’s even more fun to let the cat out of the bag. The best part about journalism is not collecting information. It’s sharing that information with the world.

Rocket Report: “No man’s land” in rocket wars; Isaacman lukewarm on SLS

China’s approach to space junk is worrisome as it begins launching its own megaconstellations.

Welcome to Edition 7.39 of the Rocket Report! Not getting your launch fix? Buckle up. We’re on the cusp of a boom in rocket launches as three new megaconstellations have either just begun or will soon begin deploying thousands of satellites to enable broadband connectivity from space. If the megaconstellations come to fruition, this will require more than a thousand launches in the next few years, on top of SpaceX’s blistering Starlink launch cadence. We discuss the topic of megaconstellations in this week’s Rocket Report.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

So, what is SpinLaunch doing now? Ars Technica has mentioned SpinLaunch, the company that literally wants to yeet satellites into space, in previous Rocket Report newsletters. This company enjoyed some success in raising money for its so-crazy-it-just-might-work idea of catapulting rockets and satellites into the sky, a concept SpinLaunch calls “kinetic launch.” But SpinLaunch is now making a hard pivot to small satellites, a move that, on its face, seems puzzling after going all-in on kinetic launch and even performing several impressive hardware tests, throwing a projectile to altitudes of up to 30,000 feet. Ars got the scoop, with the company’s CEO detailing why and how it plans to build a low-Earth orbit telecommunications constellation with 280 satellites.

Traditional versus kinetic … The planned constellation, named Meridian, is an opportunity for SpinLaunch to diversify away from being solely a launch company, according to David Wrenn, the company’s CEO. We’ve observed this in a number of companies that started out as rocket developers before branching out to satellite manufacturing or space services. Wrenn said SpinLaunch could loft all of the Meridian satellites on a single large conventional rocket, or perhaps two medium-lift rockets, and then maintain the constellation with its own kinetic launch system. A satellite communications network presents a better opportunity for profit, Wrenn said. “The launch market is relatively small compared to the economic potential of satellite communication,” he said. “Launch has generally been more of a cost center than a profit center. Satcom will be a much larger piece of the overall industry.”

Peter Beck suggests Electron is here to stay. The conventional wisdom is that the small launch vehicle business isn’t a big moneymaker. There is really only one company, Rocket Lab, that has gained traction in selling dedicated rides to orbit for small satellites. Rocket Lab’s launcher, Electron, can place payloads of up to a few hundred pounds into orbit. As soon as Rocket Lab had some success, SpaceX began launching rideshare missions on its much larger Falcon 9 rocket, cobbling together dozens of satellites on a single vehicle to spread the cost of the mission among many customers. This offers customers a lower price point than buying a dedicated launch on Electron. But Peter Beck, Rocket Lab’s founder and CEO, says his company has found a successful market providing dedicated launches for small satellites, despite price pressure from SpaceX, Space News reports. “Dedicated small launch is a real market, and it should not be confused with rideshare,” he argued. “It’s totally different.”

No man’s land … Some small satellite companies that can afford the extra cost of a dedicated launch realize the value of controlling their schedule and orbit, traits that a dedicated launch offers over a rideshare, Beck said. It’s easy to blame SpaceX for undercutting the prices of Rocket Lab and other players in this segment of the launch business, but Beck said companies that have failed or withdrawn from the small launch market didn’t have a good business plan, a good product, or good engineering. He added that the capacity of the Electron vehicle is well-suited for dedicated launch, whereas slightly larger rockets in the one-ton-to-orbit class—a category that includes Firefly Aerospace’s Alpha and Isar Aerospace’s Spectrum rockets—are an ill fit. The one-ton performance range is “no man’s land” in the market, Beck said. “It’s too small to be a useful rideshare mission, and it’s too big to be a useful dedicated rocket” for smallsats.

ULA scrubs first full-on Kuiper launch. A band of offshore thunderstorms near Florida’s Space Coast on Wednesday night forced United Launch Alliance to scrub a launch attempt of the first of dozens of missions on behalf of its largest commercial customer, Amazon, Spaceflight Now reports. The mission will use an Atlas V rocket to deploy 27 satellites for Amazon’s Project Kuiper network. It’s the first launch of what will eventually be more than 3,200 operational Kuiper satellites beaming broadband connectivity from space, a market currently dominated by SpaceX’s Starlink. As of Thursday, ULA hadn’t confirmed a new launch date, but airspace warning notices released by the FAA suggest the next attempt might occur Monday, April 14.

What’s a few more days? … This mission has been a long time coming. Amazon announced the Kuiper megaconstellation in 2019, and the company says it’s investing at least $10 billion in the project (the real number may be double that). Problems in manufacturing the Kuiper satellites, which Amazon is building in-house, delayed the program’s first full-on launch by a couple of years. Amazon launched a pair of prototype satellites in 2023, but the operational versions are different, and this mission fills the capacity of ULA’s Atlas V rocket. Amazon has booked more than 80 launches with ULA, Arianespace, Blue Origin, and SpaceX to populate the Kuiper network. (submitted by EllPeaTea)

Space Force swaps ULA for SpaceX. For the second time in six months, SpaceX will deploy a US military satellite that was sitting in storage, waiting for a slot on United Launch Alliance’s launch schedule, Ars reports. Space Systems Command, which oversees the military’s launch program, announced Monday that it is reassigning the launch of a Global Positioning System satellite from ULA’s Vulcan rocket to SpaceX’s Falcon 9. This satellite, designated GPS III SV-08 (Space Vehicle-08), will join the Space Force’s fleet of navigation satellites beaming positioning and timing signals for military and civilian users around the world. The move allows the GPS satellite to launch as soon as the end of May, the Space Force said. The military executed a similar rocket swap for a GPS mission that launched on a Falcon 9 in December.

Making ULA whole … The Space Force formally certified ULA’s Vulcan rocket for national security missions last month, so Vulcan may finally be on the cusp of delivering for the military. But there are several military payloads in the queue to launch on Vulcan before GPS III SV-08, which was already completed and in storage at its Lockheed Martin factory in Colorado. Meanwhile, SpaceX is regularly launching Falcon 9 rockets with ample capacity to add the GPS mission to the manifest. In exchange for losing the contract to launch this particular GPS satellite, the Space Force swapped a future GPS mission that was assigned to SpaceX to fly on ULA’s Vulcan instead.

Russia launches a former Navy SEAL to space. Jonny Kim, a former Navy SEAL, Harvard Medical School graduate, and now a NASA astronaut, blasted off with two cosmonaut crewmates aboard a Russian Soyuz rocket early Tuesday, CBS News reports. Three hours later, Kim and his Russian crewmates—Sergey Ryzhikov and Alexey Zubritsky—chased down the International Space Station and moved in for a picture-perfect docking aboard their Soyuz MS-27 spacecraft. “It was the trip of a lifetime and an honor to be here,” Kim told flight controllers during a traditional post-docking video conference.

Rotating back to Earth … Ryzhikov, Zubritsky, and Kim joined a crew of seven living aboard the International Space Station, temporarily raising the lab’s crew complement to 10 people. The new station residents are replacing an outgoing Soyuz crew—Alexey Ovchinin, Ivan Wagner, and Don Pettit—who launched to the ISS last September and who plan to return to Earth aboard their own spacecraft April 19 to wrap up a 219-day stay in space. This flight continues the practice of launching US astronauts on Russian Soyuz missions, part of a barter agreement between NASA and the Russian space agency that also reserves a seat on SpaceX Dragon missions for Russian cosmonauts.

China is littering in LEO. China’s construction of a pair of communications megaconstellations could cloud low Earth orbit with large spent rocket stages for decades or beyond, Space News reports. Launches for the government’s Guowang and Shanghai-backed but more commercially oriented Qianfan (Thousand Sails) constellation began in the second half of 2024, with each planned to consist of over 10,000 satellites, demanding more than a thousand launches in the coming years. Placing this number of satellites is enough to cause concern about space debris because China hasn’t disclosed its plans for removing the spacecraft from orbit at the end of their missions. It turns out there’s another big worry: upper stages.

An orbital time bomb … While Western launch providers typically deorbit their upper stages after dropping off megaconstellation satellites in space, China does not. This means China is leaving rockets in orbits high enough to persist in space for more than a century, according to Jim Shell, a space domain awareness and orbital debris expert at Novarum Tech. Space News reported on Shell’s commentary in a social media post, where he wrote that orbital debris mass in low-Earth orbit “will be dominated by PRC [People’s Republic of China] upper stages in short order unless something changes (sigh).” So far, China has launched five dedicated missions to deliver 90 Qianfan satellites into orbit. Four of these missions used China’s Long March 6A rocket, with an upper stage that has a history of breaking up in orbit, exacerbating the space debris problem. (submitted by EllPeaTea)

SpaceX wins another lunar lander launch deal. Intuitive Machines has selected a SpaceX Falcon 9 rocket to launch a lunar delivery mission scheduled for 2027, the Houston Chronicle reports. The upcoming IM-4 mission will carry six NASA payloads, including a European Space Agency-led drill suite designed to search for water at the lunar south pole. It will also include the launch of two lunar data relay satellites that support NASA’s so-called Near Space Network Services program. This will be the fourth lunar lander mission for Houston-based Intuitive Machines under the auspices of NASA’s Commercial Lunar Payload Services program.

Falcon 9 has the inside track … SpaceX almost certainly offered Intuitive Machines the best deal for this launch. The flight-proven Falcon 9 rocket is reliable and inexpensive compared to competitors and has already launched two Intuitive Machines missions, with a third one set to fly late this year. However, there’s another factor that made SpaceX a shoe-in for this contract. SpaceX has outfitted one of its launch pads in Florida with a unique cryogenic loading system to pump liquid methane and liquid oxygen propellants into the Intuitive Machines lunar lander as it sits on top of its rocket just before liftoff. The lander from Intuitive Machines uses these super-cold propellants to feed its main engine, and SpaceX’s infrastructure for loading it makes the Falcon 9 rocket the clear choice for launching it.

Time may finally be running out for SLS. Jared Isaacman, President Trump’s nominee for NASA administrator, said Wednesday in a Senate confirmation hearing that he wants the space agency to pursue human missions to the Moon and Mars at the same time, an effort that will undoubtedly require major changes to how NASA spends its money. My colleague Eric Berger was in Washington for the hearing and reported on it for Ars. Senators repeatedly sought Isaacman’s opinion on the Space Launch System, the NASA heavy-lifter designed to send astronauts to the Moon. The next SLS mission, Artemis II, is slated to launch a crew of four astronauts around the far side of the Moon next year. NASA’s official plans call for the Artemis III mission to launch on an SLS rocket later this decade and attempt a landing at the Moon’s south pole.

Limited runway … Isaacman sounded as if he were on board with flying the Artemis II mission as envisioned—no surprise, then, that the four Artemis II astronauts were in the audience—and said he wanted to get a crew of Artemis III to the lunar surface as quickly as possible. But he questioned why it has taken NASA so long, and at such great expense, to get its deep space human exploration plans moving. In one notable exchange, Isaacman said NASA’s current architecture for the Artemis lunar plans, based on the SLS rocket and Orion spacecraft, is probably not the ideal “long-term” solution to NASA’s deep space transportation plans. The smart reading of this is that Isaacman may be willing to fly the Artemis II and Artemis III missions as conceived, given that much of the hardware is already built. But everything that comes after this, including SLS rocket upgrades and the Lunar Gateway, could be on the chopping block.

Welcome to the club, Blue Origin. Finally, the Space Force has signaled it’s ready to trust Jeff Bezos’ space company, Blue Origin, for launching the military’s most precious satellites, Ars reports. Blue Origin received a contract on April 4 to launch seven national security missions for the Space Force between 2027 and 2032, an opening that could pave the way for more launch deals in the future. These missions will launch on Blue Origin’s heavy-lift New Glenn rocket, which had a successful debut test flight in January. The Space Force hasn’t certified New Glenn for national security launches, but military officials expect to do so sometime next year. Blue Origin joins SpaceX and United Launch Alliance in the Space Force’s mix of most-trusted launch providers.

A different class … The contract Blue Origin received last week covers launch services for the Space Force’s most critical space missions, requiring rocket certification and a heavy dose of military oversight to ensure reliability. Blue Origin was already eligible to launch a separate batch of missions the Space Force set aside to fly on newer rockets. The military is more tolerant of risk on these lower-priority missions, which include launches of “cookie-cutter” satellites for the Pentagon’s large fleet of missile-tracking satellites and a range of experimental payloads.

Why is SpaceX winning so many Space Force contracts? In less than a week, the US Space Force awarded SpaceX a $5.9 billion deal to make Elon Musk’s space company the Pentagon’s leading launch provider, replacing United Launch Alliance in the top position. Then, the Space Force assigned most of this year’s most lucrative launch contracts to SpaceX. As we mentioned earlier in the Rocket Report, the military also swapped a ULA rocket for a SpaceX launch vehicle for an upcoming GPS mission. So, is SpaceX’s main competitor worried Elon Musk is tipping the playing field for lucrative government contracts by cozying up to President Trump?

It’s all good, man … Tory Bruno, ULA’s chief executive, doesn’t seem too worried in his public statements, Ars reports. In a roundtable with reporters this week at the annual Space Symposium conference in Colorado, Bruno was asked about Musk’s ties with Trump. “We have not been impacted by our competitor’s position advising the president, certainly not yet,” Bruno said. “I expect that the government will follow all the rules and be fair and follow all the laws, and so we’re behaving that way.” The reason Bruno can say Musk’s involvement in the Trump administration so far hasn’t affected ULA is simple. SpaceX is cheaper and has a ready-made line of Falcon 9 and Falcon Heavy rockets available to launch the Pentagon’s satellites. ULA’s Vulcan rocket is now certified to launch military payloads, but it reached this important milestone years behind schedule.

Two Texas lawmakers are still fighting the last war. NASA has a lot to figure out in the next couple of years. Moon or Mars? Should, or when should, the Space Launch System be canceled? Can the agency absorb a potential 50 percent cut to its science budget? If Senators John Cornyn and Ted Cruz get their way, NASA can add moving a space shuttle to its list. The Lone Star State’s two Republican senators introduced the “Bring the Space Shuttle Home Act” on Thursday, CollectSpace reports. If passed by Congress and signed into law, the bill would direct NASA to take the space shuttle Discovery from the national collection at the Smithsonian National Air and Space Museum and transport it to Space Center Houston, a museum and visitor attraction next to Johnson Space Center, home to mission control and NASA’s astronaut training base. Discovery has been on display at the Smithsonian since 2012. NASA awarded museums in California, Florida, and New York the other three surviving shuttle orbiters.

Dollars and nonsense … Moving a space shuttle from Virginia to Texas would be a logistical nightmare, cost an untold amount of money, and would create a distraction for NASA when its focus should be on future space exploration. In a statement, Cruz said Houston deserves one of NASA’s space shuttles because of the city’s “unique relationship” with the program. Cornyn alleged in a statement that the Obama administration blocked Houston from receiving a space shuttle for political reasons. NASA’s inspector general found no evidence of this. On the contrary, transferring a space shuttle to Texas now would be an unequivocal example of political influence. The Boeing 747s that NASA used to move space shuttles across the country are no longer flightworthy, and NASA scrapped the handling equipment needed to prepare a shuttle for transport. Moving the shuttle by land or sea would come with its own challenges. “I can easily see this costing a billion dollars,” Dennis Jenkins, a former shuttle engineer who directed NASA’s shuttle transition and retirement program more than a decade ago, told CollectSpace in an interview. On a personal note, the presentation of Discovery at the Smithsonian is remarkable to see in person, with aerospace icons like the Concorde and the SR-71 spy plane under the same roof. Space Center Houston can’t match that.

Here are the reasons SpaceX won nearly all recent military launch contracts

“I expect that the government will follow all the rules and be fair and follow all the laws.”

In the last week, the US Space Force awarded SpaceX a $5.9 billion deal to make Elon Musk’s space company the Pentagon’s leading launch provider, and then it assigned the vast majority of this year’s most lucrative launch contracts to SpaceX.

On top of these actions, the Space Force reassigned the launch of a GPS navigation satellite from United Launch Alliance’s long-delayed Vulcan rocket to fly on SpaceX’s Falcon 9. ULA, a joint venture between Boeing and Lockheed Martin, is SpaceX’s chief US rival in the market for military satellite launches.

Given the close relationship between Musk and President Donald Trump, it’s not out of bounds to ask why SpaceX is racking up so many wins. Some plans floated by the Trump administration involving SpaceX in recent months have raised concerns over conflicts of interest.

Tory Bruno, ULA’s president and CEO, doesn’t seem too worried in his public statements. In a roundtable with reporters this week at the annual Space Symposium conference in Colorado, Bruno was asked about Musk’s ties with Trump.

“We have not been impacted by our competitor’s position advising the president, certainly not yet,” Bruno said. “I expect that the government will follow all the rules and be fair and follow all the laws, and so we’re behaving that way.”

It’s a separate concern whether the Pentagon should predominantly rely on a single provider for access to space, be it a launch company like SpaceX led by a billionaire government insider or a provider like ULA that, so far, hasn’t proven its new Vulcan rocket can meet the Space Force’s schedules.

Military officials are unanimous in the answer to that question: “No.” That’s why the Space Force is keen on adding to the Pentagon’s roster of launch providers. In the last 12 months, the Space Force has brought Blue Origin, Rocket Lab, and Stoke Space to join SpaceX and ULA in the mix for national security launches.

Results matter

The reason Bruno can say Musk’s involvement in the Trump administration so far hasn’t affected ULA is simple. SpaceX is cheaper and has a ready-made line of Falcon 9 and Falcon Heavy rockets available to launch the Pentagon’s satellites. ULA’s Vulcan rocket is now certified to launch military payloads, but it reached this important milestone years behind schedule.

The Pentagon announced Friday that SpaceX, ULA, and Blue Origin—Jeff Bezos’ space company—won contracts worth $13.7 billion to share responsibilities for launching approximately 54 of the military’s most critical space missions from 2027 through 2032. SpaceX received the lion’s share of the missions with an award for 28 launches, while ULA got 19. Blue Origin, a national security launch business newcomer, will fly seven missions.

This comes out to a 60-40 split between SpaceX and ULA, not counting Blue Origin’s seven launches, which the Space Force set aside for a third contractor. It’s a reversal of the 60-40 sharing scheme in the last big military launch competition in 2020, when ULA took the top award over SpaceX. Space Force officials anticipate Blue Origin’s New Glenn rocket will be certified for national security missions next year, allowing it to begin winning launch task orders.

Bruno said he wasn’t surprised with the outcome of this year’s launch competition, known as Phase 3 of the National Security Space Launch (NSSL) program. “We’re happy to get it,” he said Monday.

“I felt that winning 60 percent the first time was a little bit of an upset,” Bruno said of the 2020 competition with SpaceX. “I believe they expected to win 60 then … Therefore, I believed this time around that they would compete that much harder, and that I was not going to price dive in order to guarantee a win.”

While we know roughly how many launches each company will get from the Space Force, the military hasn’t determined which specific missions will fly with ULA, SpaceX, or Blue Origin. Once per year, the Space Force will convene a “mission assignment board” to divvy up individual task orders.

Simply geography

Officials announced Monday that this year’s assignment board awarded seven missions to SpaceX and two launches to ULA. The list includes six Space Force missions and three for the National Reconnaissance Office (NRO).

SpaceX’s seven wins are worth a combined $845.8 million, with an average price of $120.8 million per launch. Three will fly on Falcon 9 rockets, and four will launch on SpaceX’s Falcon Heavy.

NROL-97 on a Falcon Heavy from Cape Canaveral
USSF-15 (GPS IIIF-3) on a Falcon Heavy from Cape Canaveral
USSF-174 on a Falcon Heavy from Cape Canaveral
USSF-186 on a Falcon Heavy from Cape Canaveral
USSF-234 on a Falcon 9 from Cape Canaveral
NROL-96 on a Falcon 9 from Vandenberg
NROL-157 on a Falcon 9 from Vandenberg

The Space Force’s two orders to ULA are valued at $427.6 million, averaging $213.8 million per mission. Both missions will launch from Florida, one with a GPS navigation satellite to medium-Earth orbit and another with a next-generation geosynchronous missile warning satellite named NGG-2.

USSF-49 (GPS IIIF-2) on a Vulcan from Cape Canaveral
USSF-50 (NGG-2) on a Vulcan from Cape Canaveral

So, why did ULA only get 22 percent of this year’s task orders, instead of something closer to 40 percent? It turns out ULA was not eligible for two of these missions because the company’s West Coast launch pad for the Vulcan rocket is still under construction at Vandenberg Space Force Base. The Space Force won’t assign specific West Coast missions to ULA until the launch pad is finished and certified, according to Brig. Gen. Kristin Panzenhagen, chief of the Space Force’s “Assured Access to Space” office.

Vandenberg, a military facility on the Southern California coast, has a wide range of open ocean to the south, perfect for rockets delivering payloads into polar orbits. Rockets flown out of Cape Canaveral typically fly to the east on trajectories useful for launching satellites into the GPS network or into geosynchronous orbit.

“A company can be certified for a subset of missions while it continues to work on meeting the certification criteria for the broader set of missions,” Panzenhagen said. “In this case, ULA was not certified for West Coast launches yet. They’re working on that.”

Because of this rule, SpaceX won task orders for the NROL-96 and NROL-157 missions by default.

The Space Force’s assignment of the USSF-15 mission to SpaceX makes some sense, too. Going forward, the Space Force wants to have Vulcan and Falcon Heavy as options for adding to the GPS network. This will be the first GPS payload to launch on Falcon Heavy, allowing SpaceX engineers to complete a raft of up-front analysis and integration work. Engineers won’t have to repeat this work on future Falcon Heavy flights carrying identical GPS satellites.

From monopoly to niche

A decade ago, ULA was the sole launch provider to deploy the Pentagon’s fleet of surveillance, communication, and navigation satellites. The Air Force certified SpaceX’s Falcon 9 rocket for national security missions in May 2015, opening the market for competition for the first time since Boeing and Lockheed Martin merged their rocket divisions to create ULA in 2006.

ULA’s monopoly, which Bruno acknowledged, has now eroded into making the company a niche player in the military launch market.

“A monopoly is not healthy,” he said. “We were one for a few years before I came to ULA, and that was because no one else had the capability, and there weren’t that many missions. There weren’t enough to support many providers. There are now, so this is better.”

There are at least a couple of important reasons the Space Force is flying more missions than 10 or 20 years ago.

One is that Pentagon officials believe the United States is now in competition with a near-peer great power, China, with a rapidly growing presence in space. Military leaders say this requires more US hardware in orbit. Another is that the cost of launching something into space is lower than it was when ULA enjoyed its dominant position. SpaceX has led the charge in reducing the cost of accessing space, thanks to its success in pioneering reusable commercial rockets.

Many of the new types of missions the Space Force plans to launch in the next few years will go to low-Earth orbit (LEO), a region of space a few hundred miles above the planet. There, the Space Force plans to deploy hundreds of satellites for a global missile detection, missile tracking, and data relay network. Eventually, the military may place hundreds or more space-based interceptors in LEO as part of the “Golden Dome” missile defense program pushed by the Trump administration.

Traditionally, the military has operated missile tracking and communications satellites in much higher geosynchronous orbits some 22,000 miles (36,000 kilometers) over the equator. At that altitude, satellites revolve around the Earth at the same speed as the planet’s rotation, allowing a spacecraft to maintain a constant vigil over the same location.

The Space Force still has a few of those kinds of missions to launch, along with mobile, globe-trotting surveillance satellites and eavesdropping signals intelligence spy platforms for the National Reconnaissance Office. Bruno argues ULA’s Vulcan rocket, despite being more expensive, is best suited for these bespoke missions. So far, the Space Force’s awards seem to bear it out.

“Our rocket has a unique niche within this marketplace,” Bruno said. “There really are two kinds of missions from the rocket’s standpoint. There are ones where you drop off in LEO, and there are ones where you drop off in higher orbits. You design your rockets differently for that. It doesn’t mean we can’t drop off in LEO, it doesn’t mean [SpaceX] can’t drop off in a higher energy orbit, but we’re more efficient at those because we designed for that.”

There’s some truth in that argument. The Vulcan rocket’s upper stage, called the Centaur V, burns liquid hydrogen fuel with better fuel efficiency than the kerosene-fueled engine on SpaceX’s upper stage. And SpaceX must use the more expensive Falcon Heavy rocket for the most demanding missions, expending the rocket’s core booster to devote more propellant toward driving the payload into orbit.

SpaceX has launched at a rate nearly 34 times higher than United Launch Alliance since the start of 2023, but ULA has more experience with high-energy missions, featuring more complex maneuvers to place military payloads directly into geosynchronous orbit, and sometimes releasing multiple payloads at different locations in the geosynchronous belt.

This is one of the most challenging mission profiles for any rocket, requiring a high-endurance upper stage, like Vulcan’s Centaur V, capable of cruising through space for eight or more hours.

SpaceX has flown a long-duration version of its upper stage on several missions by adding an extended mission kit. This gives the rocket longer battery life and a custom band of thermal paint to help ensure its kerosene fuel does not freeze in the cold environment of space.

On the other hand, the overwhelming majority of SpaceX’s missions target low-Earth orbit, where Falcon 9 rockets deploy Starlink Internet satellites, send crews and cargo to the International Space Station, and regularly launch multi-payload rideshare missions. These launches maximize the Falcon 9’s efficiencies with booster recovery and reuse. SpaceX is proficient and prolific with these missions, launching them every couple of days. Launch, land, repeat.

“They tend to be more efficient at the LEO drop-offs, I’ll be honest about that,” Bruno said. “That means there’s a competitive space in the middle, and then there’s kind of these end cases. So, we’ll keep winning when it’s way over in our space, they will win when it’s way over in theirs, and then in the middle it’s kind of a toss-up for any given mission.”

Recent history seems to support Bruno’s hypothesis. Last year, SpaceX and ULA competed head-to-head for nine specific launch contracts, or task orders, in a different Space Force competition. The launches will place national security satellites into low-Earth orbit, and SpaceX won all nine of them. Since 2020, ULA has won more Space Force task orders than SpaceX for high-energy missions, although the inverse was true in this year’s round of launch orders.

The military’s launch contracting strategy gives the Space Force flexibility to swap payloads between rockets, add more missions, or deviate from the 60-40 share to SpaceX and ULA. This has precedent. Between 2020 and 2024, ULA received 54 percent of military launches, short of the 60 percent anticipated in their original contract. This amounted to ULA winning three fewer task orders, or a lost value of about $350 million, because of delays in development of the Vulcan rocket.

That’s the cost of doing business with the Pentagon. Military officials don’t want their satellites sitting on the ground. The national policy of assured access to space materialized after the Challenger accident in 1986. NASA grounded the Space Shuttle for two-and-a-half years, and the military had no other way to put its largest satellites into orbit, leading the Pentagon to accelerate development of new versions of the Atlas, Delta, and Titan rockets dating back to the 1960s.

Military and intelligence officials were again stung by a spate of failures with the Titan IV in the 1990s, when it was the only heavy-lift launcher in the Pentagon’s inventory. Then, ULA’s Delta IV Heavy rocket was the sole heavy-lifter available to the military for nearly two decades. Today, the Space Force has two heavy-lift options, and may have a third soon with Blue Origin’s New Glenn rocket.

This all has the added benefit of bringing down costs, according to Col. Doug Pentecost, deputy director of the Space Force’s Assured Access to Space directorate.

“If you bundle a bunch of missions together, you can get a better price point,” he said. “We awarded $13.7 billion. We thought this was going to cost us 15.5, so we saved $1.7 billion with this competition, showing that we have great industry out there trying to do good stuff for us.”
