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.

Astronaut hospitalized after returning from 235-day space mission

NASA said Friday one its astronauts is in a hospital in Florida for medical observation after a “normal” predawn splashdown in the Gulf of Mexico inside a SpaceX capsule.

The mission’s other three crew members were cleared to return to their home base at Johnson Space Center in Houston after their own medical evaluations, NASA said.

The hospitalized astronaut “is in stable condition and under observation as a precautionary measure,” a NASA spokesperson said in a statement. The agency did not identify the astronaut or provide any more details about their condition, citing medical privacy protections.

Strapped into their seats onside SpaceX’s Crew Dragon Endeavour spacecraft, the four-person crew splashed down just south of Pensacola, Florida, at 3: 29 am EDT (07: 29 UTC) Friday, wrapping up a 235-day mission in low-Earth orbit.

NASA extended their stay at the International Space Station earlier this year to accommodate schedule changes caused by the troubled test flight of Boeing’s Starliner spacecraft, then to wait for better weather conditions in SpaceX’s recovery zones near Florida.

Commander Matthew Dominick, pilot Michael Barratt, mission specialist Jeanette Epps, and Russian cosmonaut Alexander Grebenkin were inside SpaceX’s Dragon spacecraft for reentry and splashdown. NASA said one of its astronauts “experienced a medical issue” after the splashdown, and all four crew members were flown to Ascension Sacred Heart Pensacola for medical evaluation.

Three of the crew members were later released and departed Pensacola on a NASA business jet to fly back to Houston, according to NASA. The unidentified astronaut remains at Ascension.

“We’re grateful to Ascension Sacred Heart for its support during this time, and we are proud of our team for its quick action to ensure the safety of our crew members,” the NASA spokesperson said. “NASA will provide additional information as it becomes available.”

This mission, named Crew-8, was SpaceX’s eighth operational crew rotation flight to the space station under a multibillion-dollar commercial crew contract with NASA. This was the first flight to space for Dominick, Epps, and Grebenkin, and the third space mission for Barratt.

Roscosmos, the Russian space agency, released a photo of Grebenkin standing in Pensacola a few hours after splashdown. “After the space mission and splashdown, cosmonaut Alexander Grebenkin feels great!” Roscosmos posted on its Telegram channel.

Adapting to Earth

This is not the first time an astronaut has been hospitalized after returning to Earth, but it is uncommon. South Korean astronaut Yi So-yeon was hospitalized for back pain after experiencing higher-than-expected g-forces during reentry in a Russian Soyuz spacecraft in 2008.

Three NASA astronauts were hospitalized in Hawaii after splashing down at the end of the Apollo-Soyuz Test Project mission in 1975. The astronauts suffered lung irritation after breathing in toxic vapors from the Apollo spacecraft’s thrusters in the final moments before splashdown.

SpaceX launches mission to bring Starliner astronauts back to Earth

Ch-ch-changes —

SpaceX is bringing back propulsive landings with its Dragon capsule, but only in emergencies.

Updated

NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov lifted off Saturday from Florida’s Space Coast aboard a SpaceX Dragon spacecraft, heading for a five-month expedition on the International Space Station.

The two-man crew launched on top of SpaceX’s Falcon 9 rocket at 1: 17 pm EDT (17: 17 UTC), taking an advantage of a break in stormy weather to begin a five-month expedition in space. Nine kerosene-fueled Merlin engines powered the first stage of the flight on a trajectory northeast from Cape Canaveral Space Force Station, then the booster detached and returned to landing at Cape Canaveral as the Falcon 9’s upper stage accelerated SpaceX’s Crew Dragon Freedom spacecraft into orbit.

“It was a sweet ride,” Hague said after arriving in space. With a seemingly flawless launch, Hague and Gorbunov are on track to arrive at the space station around 5: 30 pm EDT (2130 UTC) Sunday.

Empty seats

This is SpaceX’s 15th crew mission since 2020, and SpaceX’s 10th astronaut launch for NASA, but Saturday’s launch was unusual in a couple of ways.

“All of our missions have unique challenges and this one, I think, will be memorable for a lot of us,” said Ken Bowersox, NASA’s associate administrator for space operations.

First, only two people rode into orbit on SpaceX’s Crew Dragon spacecraft, rather than the usual complement of four astronauts. This mission, known as Crew-9, originally included Hague, Gorbunov, commander Zena Cardman, and NASA astronaut Stephanie Wilson.

But the troubled test flight of Boeing’s Starliner spacecraft threw a wrench into NASA’s plans. The Starliner mission launched in June with NASA astronauts Butch Wilmore and Suni Williams. Boeing’s spacecraft reached the space station, but thruster failures and helium leaks plagued the mission, and NASA officials decided last month it was too risky to being the crew back to Earth on Starliner.

NASA selected SpaceX and Boeing for multibillion-dollar commercial crew contracts in 2014, with each company responsible for developing human-rated spaceships to ferry astronauts to and from the International Space Station. SpaceX flew astronauts for the first time in 2020, and Boeing reached the same milestone with the test flight that launched in June.

Ultimately, the Starliner spacecraft safely returned to Earth on September 6 with a successful landing in New Mexico. But it left Wilmore and Williams behind on the space station with the lab’s long-term crew of seven astronauts and cosmonauts. The space station crew rigged two temporary seats with foam inside a SpaceX Dragon spacecraft currently docked at the outpost, where the Starliner astronauts would ride home if they needed to evacuate the complex in an emergency.

This is a temporary measure to allow the Dragon spacecraft to return to Earth with six people instead of the usual four. NASA officials decided to remove two of the astronauts from the next SpaceX crew mission to free up normal seats for Wilmore and Williams to ride home in February, when Crew-9 was already slated to end its mission.

The decision to fly the Starliner spacecraft back to Earth without its crew had several second order effects on space station operations. Managers at NASA’s Johnson Space Center in Houston had to decide who to bump from the Crew-9 mission, and who to keep on the crew.

Nick Hague and Aleksandr Gorbunov ended up keeping their seats on the Crew-9 flight. Hague originally trained as the pilot on Crew-9, and NASA decided he would take Zena Cardman’s place as commander. Hague, a 49-year-old Space Force colonel, is a veteran of one long-duration mission on the International Space Station, and also experienced a rare in-flight launch abort in 2018 due to a failure of a Russian Soyuz rocket.

NASA announced the original astronaut assignments for the Crew-9 mission in January. Cardman, a 36-year-old geobiologist, would have been the first rookie astronaut without test pilot experience to command a NASA spaceflight. Three-time space shuttle flier Stephanie Wilson, 58, was the other astronaut removed from the Crew-9 mission.

The decision on who to fly on Crew-9 was a “really close call,” said Bowersox, who oversees NASA’s spaceflight operations directorate. “They were thinking very hard about flying Zena, but in this situation, it made sense to have somebody who had at least one flight under their belt.”

Gorbunov, a 34-year-old Russian aerospace engineer making his first flight to space, moved over to take pilot’s seat in the Crew Dragon spacecraft, although he remains officially designated a mission specialist. His remaining presence on the crew was preordained because of an international agreement between NASA and Russia’s space agency that provides seats for Russian cosmonauts on US crew missions and US astronauts on Russian Soyuz flights to the space station.

Bowersox said NASA will reassign Cardman and Wilson to future flights.

Operational flexibility

This was also the first launch of astronauts from Space Launch Complex-40 (SLC-40) at Cape Canaveral, SpaceX’s busiest launch pad. SpaceX has outfitted the launch pad with the equipment necessary to support launches of human spaceflight missions on the Crew Dragon spacecraft, including a more than 200-foot-tall tower and a crew access arm to allow astronauts to board spaceships on top of Falcon 9 rockets.

SLC-40 was previously based on a “clean pad” architecture, without any structures to service or access Falcon 9 rockets while they were vertical on the pad. SpaceX also installed slide chutes to give astronauts and ground crews an emergency escape route away from the launch pad in an emergency.

SpaceX constructed the crew tower last year and had it ready for the launch of a Dragon cargo mission to the space station in March. Saturday’s launch demonstrated the pad’s ability to support SpaceX astronaut missions, which have previously all departed from Launch Complex-39A (LC-39A) at NASA’s Kennedy Space Center, a few miles north of SLC-40.

Bringing human spaceflight launch capability online at SLC-40 gives SpaceX and NASA additional flexibility in their scheduling. For example, LC-39A remains the only launch pad configured to support flights of SpaceX’s Falcon Heavy rocket. SpaceX is now preparing LC-39A for a Falcon Heavy launch October 10 with NASA’s Europa Clipper mission, which only has a window of a few weeks to depart Earth this year and reach its destination at Jupiter in 2030.

With SLC-40 now certified for astronaut launches, SpaceX and NASA teams are able to support the Crew-9 and Europa Clipper missions without worrying about scheduling conflicts. The Florida spaceport now has three launch pads certified for crew flights—two for SpaceX’s Dragon and one for Boeing’s Starliner—and NASA will add a fourth human-rated launch pad with the Artemis II mission to the Moon late next year.

“That’s pretty exciting,” said Pam Melroy, NASA’s deputy administrator. “I think it’s a reflection of where we are in our space program at NASA, but also the capabilities that the United States has developed.”

Earlier this week, Hague and Gorbunov participated in a launch day dress rehearsal, when they had the opportunity to familiarize themselves with SLC-40. The launch pad has the same capabilities as LC-39A, but with a slightly different layout. SpaceX also test-fired the Falcon 9 rocket Tuesday evening, before lowering the rocket horizontal and moving it back into a hangar for safekeeping as the outer bands of Hurricane Helene moved through Central Florida.

Inside the hangar, SpaceX technicians discovered sooty exhaust from the Falcon 9’s engines accumulated on the outside of the Dragon spacecraft during the test-firing. Ground teams wiped the soot off of the craft’s solar arrays and heat shield, then repainted portions of the capsule’s radiators around the edge of Dragon’s trunk section before rolling the vehicle back to the launch pad Friday.

“It’s important that the radiators radiate heat in the proper way to space, so we had to put some some new paint on to get that back to the right emissivity and the right reflectivity and absorptivity of the solar radiation that hit those panels so it will reject the heat properly,” said Bill Gerstenmaier, SpaceX’s vice president of build and flight reliability.

Gerstenmaier also outlined a new backup ability for the Crew Dragon spacecraft to safely splash down even if all of its parachutes fail to deploy on final descent back to Earth. This involves using the capsule’s eight powerful SuperDraco thrusters, normally only used in the unlikely instance of a launch abort, to fire for a few seconds and slow Dragon’s speed for a safe splashdown.

SpaceX

“The way it works is, in the case where all the parachutes totally fail, this essentially fires the thrusters at the very end,” Gerstenmaier said. “That essentially gives the crew a chance to land safely, and essentially escape the vehicle. So it’s not used in any partial conditions. We can land with one chute out. We can land with other failures in the chute system. But this is only in the case where all four parachutes just do not operate.”

When SpaceX first designed the Crew Dragon spacecraft more than a decade ago, the company wanted to use the SuperDraco thrusters to enable the capsule to perform propulsive helicopter-like landings. Eventually, SpaceX and NASA agreed to change to a more conventional parachute-assisted splashdown.

The SuperDracos remained on the Crew Dragon spacecraft to push the capsule away from its Falcon 9 rocket during a catastrophic launch failure. The eight high-thrust engines burn hydrazine and nitrogen tetroxide propellants that combust when making contact with one another.

The backup option has been activated for some previous commercial Crew Dragon missions, but not for a NASA flight, according to Gerstenmaier. The capability “provides a tolerable landing for the crew,” he added. “So it’s a true deep, deep contingency. I think our philosophy is, rather than have a system that you don’t use, even though it’s not maybe fully certified, it gives the crew a chance to escape a really, really bad situation.”

Steve Stich, NASA’s commercial crew program manager, said the emergency propulsive landing capability will be enabled for the return of the Crew-8 mission, which has been at the space station since March. With the arrival of Hague and Gorbunov on Crew-9—and the extension of Wilmore and Williams’ mission—the Crew-8 mission is slated to depart the space station and splash down in early October.

Rocket Report: China leaps into rocket reuse; 19 people are currently in orbit

Ascendant —

Launch startups in China and Europe are borrowing ideas and rhetoric from SpaceX.

Landspace's reusable rocket test vehicle lifts off from the Jiuquan Satellite Launch Center on Wednesday, September 11, 2024.

Enlarge / Landspace’s reusable rocket test vehicle lifts off from the Jiuquan Satellite Launch Center on Wednesday, September 11, 2024.

Welcome to Edition 7.11 of the Rocket Report! Outside of companies owned by American billionaires, the most imminent advancements in reusable rockets are coming from China’s quasi-commercial launch industry. This industry is no longer nascent. After initially relying on solid-fueled rocket motors apparently derived from Chinese military missiles, China’s privately funded launch firms are testing larger launchers, with varying degrees of success, and now performing hop tests reminiscent of SpaceX’s Grasshopper and F9R Dev1 programs more than a decade ago.

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.

Landspace hops closer to a reusable rocket. Chinese private space startup Landspace has completed a 10-kilometer (33,000-foot) vertical takeoff and vertical landing test on its Zhuque-3 (ZQ-3) reusable rocket testbed, including a mid-flight engine reignition at near supersonic conditions, Aviation Week & Space Technology reports. The 18.3-meter (60-foot) vehicle took off from the Jiuquan launch base in northwestern China, ascended to 10,002 meters, and then made a vertical descent and achieved an on-target propulsive landing 3.2 kilometers (2 miles) from the launch pad. Notably, the rocket’s methane-fueled variable-thrust engine intentionally shutdown in flight, then reignited for descent, as engines would operate on future full-scale booster flybacks. The test booster used grid fins and cold gas thrusters to control itself when its main engine was dormant, according to Landspace.

“All indicators met the expected design” … Landspace hailed the test as a major milestone in the company’s road to flying its next rocket, the Zhuque-3, as soon as next year. With nine methane-fueled main engines, the Zhuque-3 will initially be able to deliver 21 metric tons (46,300 pounds) of payload into low-Earth orbit with its booster flying in expendable mode. In 2026, Landspace aims to begin recovering Zhuque-3 first-stage boosters for reuse. Landspace is one of several Chinese companies working seriously on reusable rocket designs. Another Chinese firm, Deep Blue Aerospace, says it plans a 100-kilometer (62-mile) suborbital test of a reusable booster soon, ahead of the first flight of its medium-class Nebula-1 rocket next year.

Isar Aerospace sets low bar for success on first launch. Daniel Metzler, CEO of German launch startup Isar Aerospace, stated that the first flight of the Spectrum rocket would be a success if it didn’t destroy the launch site, European Spaceflight reports. During an interview at the Handelsblatt innovation conference, Metzler was asked what he would consider a successful inaugural flight of Spectrum. “For me, the first flight will be a success if we don’t blow up the launch site,” explained Metzler. “That would probably be the thing that would set us back the most in terms of technology and time.” This tempering of expectations sounds remarkably similar to statements made by Elon Musk about SpaceX’s first flight of the Starship rocket last year.

In the catbird seat? … Isar Aerospace could be in a position to become the first in a new crop of European commercial launch companies to attempt its first orbital flight. Another German company, Rocket Factory Augsburg, recently gave up on a possible launch this year after the booster for its first launch caught fire and collapsed during a test at a launch site in Scotland. Isar plans to launch its two-stage Spectrum rocket, designed to carry up to 1,000 kilograms (2,200 pounds) of payload into low-Earth orbit, from Andøya Spaceport in Norway. Isar hasn’t publicized any schedule for the first flight of Spectrum, but there are indications the publicity-shy company is testing hardware at the Norwegian spaceport. (submitted by Ken the Bin)

FAA to introduce new orbital debris rules. The Federal Aviation Administration is moving ahead with efforts to develop rules for the disposal of upper stages as another Centaur upper stage breaks apart in orbit, Space News reports. The FAA released draft regulations on the matter for public comment one year ago, and the head of the agency’s commercial spaceflight division recently said the rules are a “high priority for our organization.” The rules would direct launch operators to dispose of upper stages in one of five ways, from controlled reentries to placement in graveyard or “disposal” orbits not commonly used by operational satellites. One change the FAA might make to the draft rules is to reduce the required timeline for an uncontrolled reentry of a disposed upper stage from no more than 25 years to a shorter timeline. “We got a lot of comments that said it should be a lot less,” said Kelvin Coleman, head of the FAA’s commercial spaceflight office. “We’re taking that into consideration.”

Upper stages are a problem … Several recent breakups involving spent upper stages in orbit have highlighted the concern that dead rocket bodies could create unnecessary space junk. Last month, the upper stage from a Chinese Long March 6A disintegrated in low-Earth orbit, creating at least 300 pieces of space debris. More recently, a Centaur upper stage from a United Launch Alliance Atlas V rocket broke apart in a much higher orbit, resulting in more than 40 pieces of debris. This was the fourth time one of ULA’s Centaur upper stages has broken up since 2018. (submitted by Ken the Bin)

NASA

On Friday NASA publicly announced a decision that has roiled the top levels of the agency’s human spaceflight program for several weeks. The space agency named the two crew members who will launch on a Crew Dragon mission set to lift off no earlier than September 24 to the International Space Station.

NASA astronaut Nick Hague will serve as the mission’s commander, and Roscosmos cosmonaut Aleksandr Gorbunov will serve as mission specialist. Instead of a usual complement of four astronauts, a two-person crew was necessitated by the need to use the Crew 9 spacecraft, Freedom, as a rescue vehicle for astronauts Butch Wilmore and Suni Williams. They flew to the station in June aboard Boeing’s Starliner vehicle, which has been deemed unsafe for them to return in.

Wilmore and Williams will join the Crew-9 increment on board the space station and fly back to Earth with Hague and Gorbunov next February.

The story behind the story

This represents a significant change from the original makeup of the Crew-9 manifest. NASA publicly named the original members of Crew-9 last January, which included three NASA astronauts and Gorbunov. It was to be commanded by Zena Cardman, piloted by Hague, with Stephanie Wilson and Gorbunov as mission specialists.

At the time, the naming of Cardman was significant—she would have been the first rookie astronaut without test pilot experience to command a NASA spaceflight. A 36-year-old geobiologist, Cardman joined NASA in 2017 and is well-regarded by her peers. The assignment of a rookie, non-test pilot to command the Crew-9 mission reflected NASA’s confidence in the self-flying capabilities of Dragon, which is intended to reach the station autonomously. The assignment was made by then-chief astronaut Reid Wiseman in 2022, and the Astronaut Office was confident that Cardman, with an experienced hand in Hague at her side, could command the mission.

The need to rescue Wilmore and Williams changed the equation. It fell upon Joe Acaba, a veteran astronaut who became chief of the Astronaut Office in February 2023, to down-select to a new crew manifest. To maintain its ongoing rotation with the Russian space program, one of the crew members needed to be Gorbunov. So Acaba had to pick from Cardman, Hague, and Wilson.

Initially, Acaba stuck with Cardman. She was the original commander of the mission, after all. But this prompted considerable dissent within the Astronaut Office, sources said. While Cardman is respected, and Dragon designed to be fully autonomous, it was asking a lot of her to be the sole NASA representative on board the vehicle. (Russian astronauts, generally, are not trained in depth on piloting US vehicles.) A non-trivial percentage of professional astronauts succumb to space sickness during the initial hours of their spaceflights.

Some members of the astronaut office argued that Hague was the safer choice. An Air Force test pilot, Hague survived a harrowing Soyuz spacecraft abort in 2018, and subsequently flew to space for more than six months in 2019. Hague, these astronauts said, was the safer choice for NASA if the agency truly sought to maximize chances of mission success.

Eventually these dissenters, with some support from the upper echelons of NASA management, prevailed, and Acaba swapped Hague for Cardman. A decision was reached before a Flight Readiness Review meeting on August 24, but it was not publicly announced until this Friday.

NASA’s official comment

“While we’ve changed crew before for a variety of reasons, downsizing crew for this flight was another tough decision to adjust to given that the crew has trained as a crew of four,” Acaba said in a news release issued Friday. “I have the utmost confidence in all our crew, who have been excellent throughout training for the mission. Zena and Stephanie will continue to assist their crewmates ahead of launch, and they exemplify what it means to be a professional astronaut.”

There was also a classy quote in the news release from Cardman, who revealed Friday that her father, Larry Cardman, passed away three weeks ago. “I am deeply proud of our entire crew,” she said. “And I am confident Nick and Alex will step into their roles with excellence. All four of us remain dedicated to the success of this mission, and Stephanie and I look forward to flying when the time is right.”

Here’s hoping her time comes very, very soon.

Cards on the table: Are Butch and Suni coming home on Starliner or Crew Dragon?

After months of consideration, NASA said Thursday that it will finally decide the fate of two astronauts on board the International Space Station, Butch Wilmore and Suni Williams, by this weekend. As soon as Saturday, the two crew members will learn whether they’ll return on a Starliner spacecraft in early September or a Crew Dragon vehicle next February.

On the eve of this fateful decision, the most consequential human spaceflight safety determination NASA has had to make in more than two decades, Ars has put together a summary of what we know, what we believe to be true, and what remains yet unknown.

Why has NASA taken so long?

Wilmore and Williams arrived at the International Space Station 11 weeks ago. Their mission was supposed to last eight days, but there was some expectation that they might stay a little longer. However, no one envisioned the crew remaining this long. That changed when, during Starliner’s flight to the space station, five of the 28 small thrusters that guide Starliner failed. After some touch-and-go operations, the astronauts and flight controllers at Johnson Space Center coaxed the spacecraft to a safe docking at the station.

This failure in space led to months of testing, both on board the vehicle in space and with similar thrusters on the ground in New Mexico. This has been followed by extensive data reviews and modeling by engineers to try to understand the root cause of the thruster problems. On Friday, lower-level managers will meet in a Program Control Board to discuss their findings and make recommendations to senior managers. Those officials, with NASA Administrator Bill Nelson presiding, will make a final decision at a Flight Readiness Review on Saturday in Houston.

What are the two options?

NASA managers will decide whether to send the astronauts home on Starliner, possibly as early as September 2, or to fly back to Earth on a Crew Dragon vehicle scheduled to be launched on September 24. To make room for Butch Wilmore and Suni Williams, this so-called “Crew-9” mission would launch with two astronauts instead of a full complement of four. Wilmore and Williams would then join this mission for their six-month increment on board the space station—their eight-day stay becoming eight months.

How are Butch and Suni feeling about this?

We don’t know, as they have not spoken to the media since it became apparent they could be in space for a long time. However, based on various sources, both of the crew members are taking it more or less in stride. They understand this is a test flight, and their training included the possibility of staying in space for an extended period of time if there were problems with Starliner.

That’s not to say it’s convenient. Both Wilmore and Williams have families back on Earth who expected them home by now, and the station was not set up for an extended stay. Wilmore, for example, has been having to sleep in a science laboratory rather than a designated sleeping area, so he has to pack up his personal things every morning.

What does seem clear is that Wilmore and Williams will accept NASA’s decision this weekend. In other words, they’re not going to stage a revolt in space. They trust NASA officials to make the right safety decision, whatever it ends up being. (So, for that matter, does Ars.)

Why is this a difficult decision?

First and foremost, NASA is concerned with getting its astronauts home safely. However, there are myriad other secondary decision factors, and bringing Butch and Suni home on Dragon instead of Starliner raises a host of new issues. Significantly among these is that it would be devastating for Boeing. Their public optics, should long-time rival SpaceX have to step in and “rescue” the crew from an “unsafe” Boeing vehicle, would be terrible. Moreover, the company has already lost $1.6 billion on the Starliner program, and there is the possibility that Boeing will shut it down. NASA does not want to lose a second provider of crew transport services to the space station.

NASA is planning to significantly delay the launch of the Crew 9 mission to the International Space Station due to ongoing concerns about the Starliner spacecraft currently attached to the station.

While the space agency has not said anything publicly, sources say NASA should announce the decision this week. Officials are contemplating moving the Crew-9 mission from its current date of August 18 to September 24, a significant slip.

Nominally, this Crew Dragon mission will carry NASA astronauts Zena Cardman, spacecraft commander; Nick Hague, pilot; and Stephanie Wilson, mission specialist; as well as Roscosmos cosmonaut Alexander Gorbunov, for a six-month journey to the space station. However, NASA has been considering alternatives to the crew lineup—possibly launching with two astronauts instead of four—due to ongoing discussions about the viability of Starliner to safely return astronauts Butch Wilmore and Suni Williams to Earth.

As of late last week, NASA still had not decided whether the Starliner vehicle, which is built and operated by Boeing, should be used to fly its two crew members home. During its launch and ascent to the space station two months ago, five small thrusters on the Starliner spacecraft failed. After extensive ground testing of the thrusters, as well as some brief in-space firings, NASA had planned to make a decision last week on whether to return Starliner with crew. However, a Flight Readiness Review planned for last Thursday was delayed after internal disagreements at NASA about the safety of Starliner.

At issue is the performance of the small reaction control system thrusters in proximity to the space station. If the right combination of them fail before Starliner has moved sufficiently far from the station, Starliner could become uncontrollable and collide with the space station. The thrusters are also needed later in the flight back to Earth to set up the critical de-orbit burn and entry in Earth’s atmosphere.

Software struggles

NASA has quietly been studying the possibility of crew returning in a Dragon for more than a month. As NASA and Boeing engineers have yet to identify a root cause of the thruster failure, the possibility of Wilmore and Williams returning on a Dragon spacecraft has increased in the last 10 days. NASA has consistently said that ‘crew safety’ will be its No. 1 priority in deciding how to proceed.

The Crew 9 delay is relevant to the Starliner dilemma for a couple of reasons. One, it gives NASA more time to determine the flight-worthiness of Starliner. However, there is also another surprising reason for the delay—the need to update Starliner’s flight software. Three separate, well-placed sources have confirmed to Ars that the current flight software on board Starliner cannot perform an automated undocking from the space station and entry into Earth’s atmosphere.

At first blush, this seems absurd. After all, Boeing’s Orbital Flight Test 2 mission in May 2022 was a fully automated test of the Starliner vehicle. During this mission, the spacecraft flew up to the space station without crew on board and then returned to Earth six days later. Although the 2022 flight test was completed by a different Starliner vehicle, it clearly demonstrated the ability of the program’s flight software to autonomously dock and return to Earth. Boeing did not respond to a media query about why this capability was removed for the crew flight test.

The world’s most-traveled crew transport spacecraft flies again

SpaceX’s oldest Crew Dragon spacecraft launched Sunday night on its fifth mission to the International Space Station, and engineers are crunching data to see if the fleet of Dragons can safely fly as many as 15 times.

It has been five years since SpaceX launched the first Crew Dragon spacecraft on an unpiloted test flight to the space station and nearly four years since SpaceX’s first astronaut mission took off in May 2020. Since then, SpaceX has put its clan of Dragons to use ferrying astronauts and cargo to and from low-Earth orbit.

Now, it’s already time to talk about extending the life of the Dragon spaceships. SpaceX and NASA, which shared the cost of developing the Crew Dragon, initially certified each capsule for five flights. Crew Dragon Endeavour, the first in the Dragon fleet to carry astronauts, is now flying for the fifth time.

This ship has spent 466 days in orbit, longer than any spacecraft designed to transport people to and from Earth. It will add roughly 180 days to its flight log with this mission.

Crew Dragon Endeavour lifted off from Florida aboard a Falcon 9 rocket at 10: 53 pm EST Sunday (03: 53 UTC Monday), following a three-day delay due to poor weather conditions across the Atlantic Ocean, where the capsule would ditch into the sea in the event of a rocket failure during the climb into orbit.

Commander Matthew Dominick, pilot Michael Barratt, mission specialist Jeanette Epps, and Russian cosmonaut Alexander Grebenkin put on their SpaceX pressure suits and strapped into their seats inside Crew Dragon Endeavour Sunday evening at NASA’s Kennedy Space Center. SpaceX loaded liquid propellants into the rocket, while ground teams spent the final hour of the countdown evaluating a small crack discovered on Dragon’s side hatch seal. Managers ultimately cleared the spacecraft for launch after considering whether the crack could pose a safety threat during reentry at the end of the mission.

“We are confident that we understand the issue and can still fly the whole mission safely,” a member of SpaceX’s mission control team told the crew inside Dragon.

This mission, known as Crew-8, launched on a brand-new Falcon 9 booster, which returned to landing a few minutes after liftoff at Cape Canaveral Space Force Station. The Falcon 9’s upper stage released the Dragon spacecraft into orbit about 12 minutes after liftoff. The four-person crew will dock at the space station around 3 am EST (0800 UTC) Tuesday.

Crew-8 will replace the four-person Crew-7 team that has been at the space station since last August. Crew-7 will return to Earth in about one week on SpaceX’s Crew Dragon Endurance spacecraft, which is flying in space for the third time.

The Crew-8 mission came home for a reentry and splashdown off the coast of Florida in late August of this year, wrapping up Crew Dragon Endeavour’s fifth trip to space. This is the current life limit for a Crew Dragon spacecraft, but don’t count out Endeavour just yet.

Fleet management

“Right now, we’re certified for five flights on Dragon, and we’re looking at extending that life out,” said Steve Stich, NASA’s commercial crew program manager. “I think the goal would be for SpaceX to say 15 flights of Dragon. We may not get there in every single system.”

One by one, engineers at SpaceX and NASA are looking at Dragon’s structural skeleton, composite shells, rocket engines, valves, and other components to see how much life is left in them. Some parts of the spacecraft slowly fatigue from the stresses of each launch, reentry, and splashdown, along with the extreme temperature swings the capsule sees thousands of times in orbit. Each Draco thruster on the spacecraft is certified for a certain number of firings.

Some components are already approved for 15 flights, Stich said in a recent press conference. “Some, we’re still in the middle of working on,” he said. “Some of those components have to go through some re-qualification to make sure that they can make it out to 15 flights.”

Re-qualifying a component on a spacecraft typically involves putting hardware through extensive testing on the ground. Because SpaceX reuses hardware, engineers can remove a part from a flown Dragon spacecraft and put it through qualification testing. NASA will get the final say in certifying the Dragon spacecraft for additional flights because the agency is SpaceX’s primary customer for crew missions.

The Dragon fleet is flying more often than SpaceX or NASA originally anticipated. The main reason for this is that Boeing, NASA’s other commercial crew contractor, is running about four years behind SpaceX in getting to its first astronaut launch on the Starliner spacecraft.

When NASA selected SpaceX and Boeing for multibillion-dollar commercial crew contracts in 2014, the agency envisioned alternating between Crew Dragon and Starliner flights every six months to rotate four-person crews at the International Space Station. With Boeing’s delays, SpaceX has picked up the slack.
