Welcome to Edition 6.50 of the Rocket Report! SpaceX launched its 10th Falcon Heavy rocket this week with the GOES-U weather satellite for NOAA, and this one was a beauty. The late afternoon timing of the launch and atmospheric conditions made for great photography. Falcon Heavy has become a trusted rocket for the US government, and its next flight in October will deploy NASA’s Europa Clipper spacecraft on the way to explore one of Jupiter’s enigmatic icy moons.

Sir Peter Beck dishes on launch business. Ars spoke with the recently knighted Peter Beck, founder and CEO of Rocket Lab, on where his scrappy company fits in a global launch marketplace dominated by SpaceX. Rocket Lab racked up the third-most number of orbital launches by any US launch company (it’s headquartered in California but primarily assembles and launches rockets in New Zealand). SpaceX’s rideshare launch business with the Falcon 9 rocket is putting immense pressure on small launch companies like Rocket Lab. However, Beck argues his Electron rocket is a bespoke solution for customers desiring to put their satellite in a specific place at a specific time, a luxury they can’t count on with a SpaceX rideshare.

Ruthlessly efficient … A word that Beck returned to throughout his interview with Ars was “ruthless.” He said Rocket Lab’s success is a result of the company being “ruthlessly efficient and not making mistakes.” At one time, Rocket Lab was up against Virgin Orbit in the small launch business, and Virgin Orbit had access to capital through billionaire Richard Branson. Now, SpaceX is the 800-pound gorilla in the market. “We have a saying here at Rocket Lab that we have no money, so we have to think. We’ve never been in a position to outspend our competitors. We just have to out-think them. We have to be lean and mean.”

Firefly reveals plans for new launch sites. Firefly Aerospace plans to use the state of Virginia-owned launch pad at NASA’s Wallops Flight Facility for East Coast launches of its Alpha small-satellite rocket, Aviation Week reports. The company plans to use Pad 0A for US military and other missions, particularly those requiring tight turnaround between procurement and launch. This is the same launch pad previously used by Northrop Grumman’s Antares rocket, and it’s the soon-to-be home of the Medium Launch Vehicle (MLV) jointly developed by Northrop and Firefly. The launch pad will be configured for Alpha launches beginning in 2025, according to Firefly, which previously planned to develop an Alpha launch pad at Cape Canaveral Space Force Station in Florida. Now, Alpha and MLV rockets will fly from the same site on the East Coast, while Alpha will continue launching from the West Coast at Vandenberg Space Force Base, California.

Hello, Sweden… A few days after the announcement for launches from Virginia, Firefly unveiled a collaborative agreement with Swedish Space Corporation to launch Alpha rockets from the Esrange Space Center in Sweden as soon as 2026. Esrange has been the departure point for numerous suborbital and sounding rocket for nearly 50 years, but the spaceport is being upgraded for orbital satellite launches. A South Korean startup named Perigee Aerospace announced in May it signed an agreement to be the first user of Esrange’s orbital launch capability. Firefly is the second company to make plans to launch satellites from the remote site in northern Sweden. (submitted by Ken the Bin and brianrhurley)

China hops closer to reusable rockets. The Shanghai Academy of Spaceflight Technology (SAST), part of China’s apparatus of state-owned aerospace companies, has conducted the country’s highest altitude launch and landing test so far as several teams chase reusable rocket capabilities, Space News reports. A 3.8-meter-diameter (9.2-foot) test article powered by three methane liquid-oxygen engines lifted off from the Gobi Desert on June 23 and soared to an altitude of about 12 kilometers (7.5 miles) before setting down successfully for a vertical propulsive touchdown on landing legs at a nearby landing area. SAST will follow up with a 70-kilometer (43.5-mile) suborbital test using grid fins for better control. A first orbital flight of the new reusable rocket is planned for 2025.

Lots of players … If you don’t exclusively follow China’s launch sector, you should be forgiven for being unable to list all the companies working on new reusable rockets. Late last year, a Chinese startup named iSpace flew a hopper rocket testbed to an altitude of several hundred meters as part of a development program for the company’s upcoming partially reusable Hyperbola 2 rocket. A company named Space Pioneer plans to launch its medium-class Tianlong 3 rocket for the first time later this year. Tianlong 3 looks remarkably like SpaceX’s Falcon 9, and its first stage will eventually be made reusable. China recently test-fired engines for the government’s new Long March 10, a partially reusable rocket planned to become China’s next-generation crew launch vehicle. These are just a few of the reusable rocket programs in China. (submitted by Ken the Bin)

Spanish launch startup invests in Kourou. PLD Space says it is ready to start construction at a disused launch complex at the Guiana Space Center in Kourou, French Guiana. The Spanish launch startup announced this week a 10 million euro ($10.7 million) investment in the launch complex for its Miura 5 rocket, with preparations of the site set to begin “after the summer.” The launch pad was previously used by the French Diamant rocket in the 1970s and is located several miles away from the launch pads used by the European Ariane 6 and Vega rockets. PLD Space is on track to become the first fully commercial company to launch from the spaceport in South America.

Free access to space … Also this week, PLD Space announced a new program to offer space aboard the first two flights of its Miura 5 rocket for free, European Spaceflight reports. The two-stage Miura 5 rocket will be capable of delivering about a half-ton of payload mass into a Sun-synchronous orbit. PLD Space will offer free launch services aboard the first two Miura 5 flights, which are expected to take place in late 2025 and early 2026. The application process will close on July 30, and winning proposals will be announced on November 30. (submitted by Ken the Bin and EllPeaTea)

Blue Origin joins SpaceX and ULA in new round of military launch contracts

Playing with the big boys —

“Lane 1 serves our commercial-like missions that can accept more risk.”

After years of lobbying, protests, and bidding, Jeff Bezos’s space company is now a military launch contractor.

The US Space Force announced Thursday that Blue Origin will compete with United Launch Alliance and SpaceX for at least 30 military launch contracts over the next five years. These launch contracts have a combined value of up to $5.6 billion.

This is the first of two major contract decisions the Space Force will make this year as the military seeks to foster more competition among its roster of launch providers and reduce its reliance on just one or two companies.

For more than a decade following its formation from the merger of Boeing and Lockheed Martin rocket programs, ULA was the sole company certified to launch the military’s most critical satellites. This changed in 2018, when SpaceX started launching national security satellites for the military. In 2020, despite protests from Blue Origin seeking eligibility, the Pentagon selected ULA and SpaceX to continue sharing launch duties.

The National Security Space Launch (NSSL) program is in charge of selecting contractors to deliver military surveillance, navigation, and communications satellites into orbit.

Over the next five years, the Space Force wants to tap into new launch capabilities from emerging space companies. The procurement approach for this new round of contracts, known as NSSL Phase 3, is different from the way the military previously bought launch services. Instead of grouping all national security launches into one monolithic contract, the Space Force is dividing them into two classifications: Lane 1 and Lane 2.

The Space Force’s contract announced Thursday was for Lane 1, which is for less demanding missions to low-Earth orbit. These missions include smaller tech demos, experiments, and launches for the military’s new constellation of missile-tracking and data-relay satellites, an effort that will eventually include hundreds or thousands of spacecraft managed by the Pentagon’s Space Development Agency.

This fall, the Space Force will award up to three contracts for Lane 2, which covers the government’s most sensitive national security satellites, which require “complex security and integration requirements.” These are often large, heavy spacecraft weighing many tons and sometimes needing to go to orbits thousands of miles from Earth. The Space Force will require Lane 2 contractors to go through a more extensive certification process than is required in Lane 1.

“Today marks the beginning of this innovative, dual-lane approach to launch service acquisition, whereby Lane 1 serves our commercial-like missions that can accept more risk and Lane 2 provides our traditional, full mission assurance for the most stressing heavy-lift launches of our most risk-averse missions,” said Frank Calvelli, assistant secretary of the Air Force for space acquisition and integration.

Meeting the criteria

The Space Force received seven bids for Lane 1, but only three companies met the criteria to join the military’s roster of launch providers. The basic requirement to win a Lane 1 contract was for a company to show its rocket can place at least 15,000 pounds of payload mass into low-Earth orbit, either on a single flight or over a series of flights within a 90-day period.

The bidders also had to substantiate their plan to launch the rocket they proposed to use for Lane 1 missions by December 15 of this year. A spokesperson for Space Systems Command said SpaceX proposed using their Falcon 9 and Falcon Heavy rockets, and ULA offered its Vulcan rocket. Those launchers are already flying. Blue Origin proposed its heavy-lift New Glenn rocket, slated for an inaugural test flight no earlier than September.

“As we anticipated, the pool of awardees is small this year because many companies are still maturing their launch capabilities,” said Brig. Gen. Kristin Panzenhagen, program executive officer for the Space Force’s assured access to space division. “Our strategy accounted for this by allowing on-ramp opportunities every year, and we expect increasing competition and diversity as new providers and systems complete development.”

The Space Force plans to open up the first on-ramp opportunity for Lane 1 as soon as the end of this year. Companies with medium-lift rockets in earlier stages of development, such as Rocket Lab, Relativity Space, Firefly Aerospace, and Stoke Space, will have the chance to join ULA, SpaceX, and Blue Origin in the Lane 1 pool at that time. The structure of the NSSL Phase 3 contracts allow the Pentagon to take advantage of emerging launch capabilities as soon as they become available, according to Calvelli.

In a statement, Panzenhagen said having additional launch providers will increase the Space Force’s “resiliency” in a time of increasing competition between the US, Russia, and China in orbit. “Launching more risk-tolerant satellites on potentially less mature launch systems using tailored independent government mission assurance could yield substantial operational responsiveness, innovation, and savings,” Panzenhagen said.

More competition, theoretically, will also deliver lower launch prices to the Space Force. SpaceX and Blue Origin rockets are partially reusable, while ULA eventually plans to recover and reuse Vulcan main engines.

Over the next five years, Space Systems Command will dole out fixed-price “task orders” to ULA, SpaceX, and Blue Origin for groups of Lane 1 missions. The first batch of missions up for awards in Lane 1 include seven launches for the Space Development Agency’s missile tracking mega-constellation, plus a task order for the National Reconnaissance Office, the government’s spy satellite agency. However, military officials require a rocket to have completed at least one successful orbital launch to win a Lane 1 task order, and Blue Origin’s New Glenn doesn’t yet satisfy this requirement.

The Space Force will pay Blue Origin $5 million for an “initial capabilities assessment” for Lane 1. SpaceX and ULA, the military’s incumbent launch contractors, will each receive $1.5 million for similar assessments.

ULA, SpaceX, and Blue Origin are also the top contenders to win Lane 2 contracts later this year. In order to compete in Lane 2, a launch provider must show it has a plan for its rockets to meet the Space Force’s stringent certification requirements by October 1, 2026. SpaceX’s Falcon 9 and Falcon Heavy are already certified, and ULA’s Vulcan is on a path to achieve this milestone by the end of this year, pending a successful second test flight in the next few months. A successful debut of New Glenn by the end of this year would put the October 2026 deadline within reach of Blue Origin.

Let’s unpack some questions about Russia’s role in North Korea’s rocket program

Russian President Vladimir Putin will reportedly visit North Korea later this month, and you can bet collaboration on missiles and space programs will be on the agenda.

The bilateral summit in Pyongyang will follow a mysterious North Korean rocket launch on May 27, which ended in a fireball over the Yellow Sea. The fact that this launch fell short of orbit is not unusual—two of the country’s three previous satellite launch attempts failed. But North Korea’s official state news agency dropped some big news in the last paragraph of its report on the May 27 launch.

The Korean Central News Agency called the launch vehicle a “new-type satellite carrier rocket” and attributed the likely cause of the failure to “the reliability of operation of the newly developed liquid oxygen + petroleum engine” on the first stage booster. A small North Korean military spy satellite was destroyed. The fiery demise of the North Korean rocket was captured in a video recorded by the Japanese news broadcaster NHK.

Petroleum almost certainly means kerosene, a refined petroleum fuel used on a range of rockets, including SpaceX’s Falcon 9, United Launch Alliance’s Atlas V, and Russia’s Soyuz and Angara.

“The North Koreans are clearly toying with us,” said Jeffrey Lewis, a nonproliferation expert at the Middlebury Institute of International Studies. “They went out of their way to tell us what the propellant was, which is very deliberate because it’s a short statement and they don’t normally do that. They made a point of doing that, so I suspect they want us to be wondering what’s going on.”

Surprise from Sohae

Veteran observers of North Korea’s rocket program anticipated the country’s next satellite launch would use the same Chollima-1 rocket it used on three flights last year. But North Korea’s official statement suggests this was something different, and entirely unexpected, at least by anyone without access to classified information.

Ahead of the launch, North Korea released warning notices outlining the drop zones downrange where sections of the rocket would fall into the sea after lifting off from Sohae Satellite Launching Station on the country’s northwestern coast.

A day before the May 27 launch, South Korea’s Yonhap news agency reported a “large number of Russian experts” entered North Korea to support the launch effort. A senior South Korean defense official told Yonhap that North Korea staged more rocket engine tests than expected during the run-up to the May 27 flight.

Then, North Korea announced that this wasn’t just another flight of the Chollima-1 rocket but something new. The Chollima 1 used the same mix of hydrazine and nitrogen tetroxide propellants as North Korea’s ballistic missiles. This combination of toxic propellants has the benefit of simplicity—these liquids are hypergolic, meaning they combust upon contact with one another. No ignition source is needed.

Kerosene and liquid oxygen are nontoxic and more fuel-efficient. But liquid oxygen has to be kept at super-cold temperatures, requiring special handling and insulation to prevent boil-off as it is loaded into the rocket.

Countdown begins for third try launching Boeing’s Starliner crew capsule

Going today? —

Astronauts Butch Wilmore and Suni Williams have been in prelaunch quarantine for six weeks.

Fresh off repairs at the launch pad in Florida, United Launch Alliance engineers restarted the countdown overnight for the third attempt to send an Atlas V rocket and Boeing’s Starliner spacecraft on a test flight to the International Space Station.

NASA astronauts Butch Wilmore and Suni Williams were expected to awake early Wednesday, put on their blue pressure suits, and head to the launch pad at Cape Canaveral Space Force Station to board the Starliner capsule on top of the 172-foot-tall Atlas V rocket.

Once more through the door

Wilmore and Williams have done this twice before in hopes of launching into space on the first crew flight of Boeing’s Starliner spacecraft. A faulty valve on the Atlas V rocket prevented liftoff May 6, then engineers discovered a helium leak on the Starliner capsule itself. After several weeks of troubleshooting, NASA and Boeing officials decided to proceed with another launch attempt Saturday.

Everything seemed to be coming together for Boeing’s long-delayed crew test flight until a computer problem triggered an automatic hold in the countdown less than four minutes before liftoff. Technicians from United Launch Alliance (ULA), the Atlas V rocket’s builder and operator, traced the problem to a failed power distribution source connected to a ground computer responsible for controlling the final phase of the countdown.

The instantaneous launch opportunity Wednesday is set for 10: 52 am EDT (14: 52 UTC), when the launch site at Cape Canaveral passes underneath the space station’s orbital plane. Forecasters predict a 90 percent chance of good weather for launch. You can watch NASA’s live coverage in the video embedded below.

The countdown began late Tuesday night with the power-up of the Atlas V rocket, which was set to be filled with cryogenic liquid hydrogen and liquid oxygen propellants around 5 am EDT (09: 00 UTC). Kerosene fuel was loaded into the Atlas V’s first-stage booster prior to the mission’s first launch attempt in early May.

The two Starliner astronauts departed crew quarters at NASA’s Kennedy Space Center for the 20-minute drive to the launch pad, where they arrived shortly before 8 am EDT (12: 00 UTC) to climb into their seats inside the Starliner capsule. After pressure checks of the astronauts’ suits and Starliner’s crew cabin, ground teams will evacuate the pad about an hour before launch.

Assuming all systems are “go” for launch, the Atlas V will ignite its Russian-made RD-180 main engine and two solid-fueled boosters to vault away from Cape Canaveral and head northeast over the Atlantic Ocean. Wilmore and Williams will be not only the first people to fly in space on Boeing’s Starliner, but also the first astronauts to ride on an Atlas V rocket, which has flown 99 times before with satellites for the US military, NASA, and commercial customers.

The rocket’s Centaur upper stage will deploy Starliner into space around 15 minutes after liftoff. A critical burn by Starliner’s engines will happen around 31 minutes into the flight to finish the task of placing it into low-Earth orbit, setting it up for an automated docking at the International Space Station at 12: 15 pm EDT (16: 15 UTC) Thursday.

The two-person crew will stay on the station for at least a week, although a mission extension is likely if the mission is going well. Officials may decide to extend the mission to complete more tests or to wait for optimal weather conditions at Starliner’s primary and backup landing sites in New Mexico and Arizona. When weather conditions look favorable, Starliner will undock from the space station and head for landing under parachutes.

The crew test flight is a prerequisite to Boeing’s crew capsule becoming operational for NASA, which awarded multibillion-dollar commercial crew contracts to Boeing and SpaceX in 2014. SpaceX’s Crew Dragon started flying astronauts in 2020, while Boeing’s project has been stricken by years of delays.

Wilmore and Williams, both former US Navy test pilots, will take over manual control of Starliner at several points during the test flight. They will evaluate the spacecraft’s flying characteristics and accommodations for future flights, which will carry four astronauts at a time rather than two.

“The expectation from the media should not be perfection,” Wilmore told Ars earlier this year. “This is a test flight. Flying and operating in space is hard. It’s really hard, and we’re going to find some stuff. That’s expected. It’s the first flight where we are integrating the full capabilities of this spacecraft.”

SpaceX is about to launch Starship again—the FAA will be more forgiving this time

SpaceX

The Federal Aviation Administration approved the commercial launch license for the fourth test flight of SpaceX’s Starship rocket Tuesday, with liftoff from South Texas targeted for just after sunrise Thursday.

“The FAA has approved a license authorization for SpaceX Starship Flight 4,” the agency said in a statement. “SpaceX met all safety and other licensing requirements for this test flight.”

Shortly after the FAA announced the launch license, SpaceX confirmed plans to launch the fourth test flight of the world’s largest rocket at 7: 00 am CDT (12: 00 UTC) Thursday. The launch window runs for two hours.

This flight follows three prior demonstration missions, each progressively more successful, of SpaceX’s privately developed mega-rocket. The last time Starship flew—on March 14—it completed an eight-and-a-half minute climb into space, but the ship was unable to maneuver itself as it coasted nearly 150 miles (250 km) above Earth. This controllability problem caused the rocket to break apart during reentry.

On Thursday’s flight, SpaceX officials will expect the ascent portion of the test flight to be similarly successful to the launch in March. The objectives this time will be to demonstrate Starship’s ability to survive the most extreme heating of reentry, when temperatures peak at 2,600° Fahrenheit (1,430° Celsius) as the vehicle plunges into the atmosphere at more than 20 times the speed of sound.

SpaceX officials also hope to see the Super Heavy booster guide itself toward a soft splashdown in the Gulf of Mexico just offshore from the company’s launch site, known as Starbase, in Cameron County, Texas.

“The fourth flight test turns our focus from achieving orbit to demonstrating the ability to return and reuse Starship and Super Heavy,” SpaceX wrote in an overview of the mission.

Last month, SpaceX completed a “wet dress rehearsal” at Starbase, where the launch team fully loaded the rocket with cryogenic methane and liquid oxygen propellants. Before the practice countdown, SpaceX test-fired the booster and ship at the launch site. More recently, technicians installed components of the rocket’s self-destruct system, which would activate to blow up the rocket if it flies off course.

Then, on Tuesday, SpaceX lowered the Starship upper stage from the top of the Super Heavy booster, presumably to perform final touch-ups to the ship’s heat shield, composed of 18,000 hexagonal ceramic tiles to protect its stainless-steel structure during reentry. Ground teams were expected to raise the ship, or upper stage, back on top of the booster sometime Wednesday, returning the rocket to its full height of 397 feet (121 meters) ahead of Thursday morning’s launch window.

The tick-tock of Starship’s fourth flight

If all goes according to plan, SpaceX’s launch team will start loading 10 million pounds of super-cold propellants into the rocket around 49 minutes before liftoff Thursday. The methane and liquid oxygen will first flow into the smaller tanks on the ship, then into the larger tanks on the booster.

The rocket should be fully loaded about three minutes prior to launch, and, following a sequence of automated checks, the computer controlling the countdown will give the command to light the booster’s 33 Raptor engines. Three seconds later, the rocket will begin its vertical climb off the launch mount, with its engines capable of producing more than 16 million pounds of thrust at full power.

Heading east from the Texas Gulf Coast, the rocket will exceed the speed of sound in about a minute, then begin shutting down its 33 main engines around 2 minutes and 41 seconds after liftoff. Then, just as the Super Heavy booster jettisons to begin a descent back to Earth, Starship’s six Raptor engines will ignite to continue pushing the upper portion of the rocket into space. Starship’s engines are expected to burn until T+ 8 minutes, 23 seconds, accelerating the rocket to near-orbital velocity with enough energy to fly an arcing trajectory halfway around the world to the Indian Ocean.

All of this will be similar to the events of the last Starship launch in March. What differs in the flight plan this time involves the attempts to steer the booster and ship back to Earth. This is important to lay the groundwork for future flights, when SpaceX wants to bring the Super Heavy booster—the size of the fuselage of a Boeing 747 jumbo jet—to a landing back at its launch pad. Eventually, SpaceX also intends to recover reusable Starships back at Starbase or other spaceports.

This infographic released by SpaceX shows the flight profile for SpaceX's fourth Starship launch.

SpaceX

Based on the results of the March test flight, SpaceX still has a lot to prove in these areas. On that flight, the engines on the Super Heavy booster could not complete all the burns required to guide the rocket toward the splashdown zone in the Gulf of Mexico. The booster lost control as it plummeted toward the ocean.

Engineers traced the failure to blockage in a filter where liquid oxygen flows into the Raptor engines. Notably, a similar problem occurred on the second Starship test flight last November. The Super Heavy booster awaiting launch Thursday has additional hardware to improve propellant filtration capabilities, according to SpaceX. The company also implemented “operational changes” on the booster for the upcoming test flight, including to jettison the Super Heavy’s staging ring, which sits between the booster and ship during launch, to reduce the rocket’s mass during descent.

SpaceX has a lot of experience bringing back its fleet of Falcon 9 boosters. The company now boasts a streak of more than 240 successful rocket landings in a row, so it’s reasonable to expect SpaceX will overcome the challenge of recovering the larger Super Heavy booster.

Boeing’s Starliner test flight scrubbed again after hold in final countdown

Hold Hold Hold —

The ground launch sequencer computer called a hold at T-minus 3 minutes, 50 seconds.

A computer controlling the Atlas V rocket’s countdown triggered an automatic hold less than four minutes prior to liftoff of Boeing’s commercial Starliner spacecraft Saturday, keeping the crew test flight on the ground at least a few more days.

NASA astronauts Butch Wilmore and Suni Williams were already aboard the spacecraft when the countdown stopped due to a problem with a ground computer. “Hold. Hold. Hold,” a member of Atlas V launch team called out on an audio feed.

With the hold, the mission missed an instantaneous launch opportunity at 12: 25 pm EDT (16: 25 UTC), and later Saturday, NASA announced teams will forego a launch opportunity Sunday. The next chance to send Starliner into orbit will be 10: 52 am EDT (14: 52 UTC) Wednesday. The mission has one launch opportunity every one-to-two days, when the International Space Station’s orbital track moves back into proper alignment with the Atlas V rocket’s launch pad in Florida.

Wilmore and Williams will take the Starliner spacecraft on its first crew flight into low-Earth orbit. The capsule will dock with the International Space Station around a day after launch, spend at least a week there, then return to a parachute-assisted landing at one of two landing zones in New Mexico or Arizona. Once operational, Boeing’s Starliner will join SpaceX’s Crew Dragon capsule to give NASA two independent human-rated spacecraft for transporting astronauts to and from the space station.

It’s been a long road to get here with the Starliner spacecraft, and there’s more work to do before the capsule’s long-delayed first flight with astronauts.

Technicians from United Launch Alliance, builder of the Atlas V rocket, will begin troubleshooting the computer glitch at the launch pad Saturday evening, after draining propellant from the launch vehicle. Early indications suggest that a card in one of three computers governing the final minutes of the Atlas V’s countdown didn’t boot up as quickly as anticipated.

“You can imagine a large rack that is a big computer where the functions of the computer as a controller are broken up separately into individual cards or printed wire circuit boards with their logic devices,” said Tory Bruno, ULA’s president and CEO. “They’re all standalone, but together it’s an integrated controller.”

The computers are located at the launch pad inside a shelter near the base of the Atlas V rocket at Cape Canaveral Space Force Station. All three computers must be fully functioning in the final phase of the countdown to ensure triple redundancy. At the moment of liftoff, these computers control things like retracting umbilical lines and releasing bolts holding the rocket to its mobile launch platform.

Two of the computers activated as the final countdown sequence began at T-minus 4 minutes. A single card in the third computer took about six more seconds to come online, although it did boot up eventually, Bruno said.

“Two came up normally and the third one came up, but it was slow to come up, and that tripped a red line,” he said.

A disappointment

Wilmore and Williams, both veteran astronauts and former US Navy test pilots, exited the Starliner spacecraft with the help of Boeing’s ground team. They returned to NASA crew quarters at the nearby Kennedy Space Center to wait for the next launch attempt.

The schedule for the next try will depend on what ULA workers find when they access the computers at the launch pad. Officials initially said they could start another launch countdown early Sunday if they found a simple solution to the computer problem, such as swapping out a faulty card. The computers are networked together, but the architecture is designed with replaceable cards, each responsible for different functions during the countdown, to allow for a quick fix without having to replace the entire unit, Bruno said.

Later Saturday, NASA announced the launch won’t happen Sunday, giving teams additional time to assess the computer issue. The next launch opportunities are Wednesday and Thursday.

Bruno said ULA’s engineers suspect a hardware problem or a network communication glitch caused the computer issue during Saturday’s countdown. That is what ULA’s troubleshooting team will try to determine overnight. NASA said officials will share another update Sunday.

If it doesn’t get off the ground by Thursday, the Starliner test flight could face a longer delay to allow time for ULA to change out limited-life batteries on the Atlas V rocket. Bruno said the battery swap would take about 10 days.

Saturday’s aborted countdown was the latest in a string of delays for Boeing’s Starliner program. The spacecraft’s first crew test flight is running seven years behind the schedule Boeing announced when NASA awarded the company a $4.2 billion contract for the crew capsule in 2014. Put another way, Boeing has arrived at this moment nine years after the company originally said the spacecraft could be operational, when the program was first announced in 2010.

“Of course, this is emotionally disappointing,” said Mike Fincke, a NASA astronaut and a backup to Wilmore and Williams on the crew test flight. “I know Butch and Suni didn’t sound disappointed when we heard them on the loops, and it’s because it comes back to professionalism.”

NASA and Boeing were on the cusp of launching the Starliner test flight May 6, but officials called off the launch attempt due to a valve problem on the Atlas V rocket. Engineers later discovered a helium leak on the Starliner spacecraft’s service module, but managers agreed to proceed with the launch Saturday if the leak did not worsen during the countdown.

A check of the helium system Saturday morning showed the leak rate had decreased from a prior measurement, and it was no longer a constraint to launch. Instead, a different problem emerged to keep Starliner on Earth.

“Everybody is a little disappointed, but you kind of roll your sleeves up and get right back to work,” said Steve Stich, manager of NASA’s commercial crew program.

Welcome to Edition 6.46 of the Rocket Report! It looks like we will be covering the crew test flight of Boeing’s Starliner spacecraft and the fourth test flight of SpaceX’s giant Starship rocket over the next week. All of this is happening as SpaceX keeps up its cadence of flying multiple Starlink missions per week. The real stars are the Ars copy editors helping make sure our stories don’t use the wrong names.

Another North Korean launch failure. North Korea’s latest attempt to launch a rocket with a military reconnaissance satellite ended in failure due to the midair explosion of the rocket during the first-stage flight this week, South Korea’s Yonhap News Agency reports. Video captured by the Japanese news organization NHK appears to show the North Korean rocket disappearing in a fireball shortly after liftoff Monday night from a launch pad on the country’s northwest coast. North Korean officials acknowledged the launch failure and said the rocket was carrying a small reconnaissance satellite named Malligyong-1-1.

Russia’s role? … Experts initially thought the pending North Korean launch, which was known ahead of time from international airspace warning notices, would use the same Chŏllima 1 rocket used on three flights last year. But North Korean statements following the launch Monday indicated the rocket used a new propulsion system burning a petroleum-based fuel, presumably kerosene, with liquid oxygen as the oxidizer. The Chŏllima 1 rocket design used a toxic mixture of hypergolic hydrazine and nitrogen tetroxide as propellants. If North Korea’s statement is true, this would be a notable leap in the country’s rocket technology and begs the question of whether Russia played a significant role in the launch. Last year, Russian President Vladimir Putin pledged more Russian support for North Korea’s rocket program in a meeting with North Korean leader Kim Jong Un. (submitted by Ken the Bin and Jay500001)

Rocket Lab deploys small NASA climate satellite. Rocket Lab is in the midst of back-to-back launches for NASA, carrying identical climate research satellites into different orbits to study heat loss to space in Earth’s polar regions. The Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) satellites are each about the size of a shoebox, and NASA says data from PREFIRE will improve computer models that researchers use to predict how Earth’s ice, seas, and weather will change in a warming world. “The difference between the amount of heat Earth absorbs at the tropics and that radiated out from the Arctic and Antarctic is a key influence on the planet’s temperature, helping to drive dynamic systems of climate and weather,” NASA said in a statement.

Twice in a week… NASA selected Rocket Lab’s Electron launch vehicle to deliver the two PREFIRE satellites into orbit on two dedicated rides rather than launching at a lower cost on a rideshare mission. This is because scientists want the satellites flying at the proper alignment to ensure they fly over the poles several hours apart, providing the data needed to measure how the rate at which heat radiates from the polar regions changes over time. The first PREFIRE launch occurred on May 25, and the next one is slated for May 31. Both launches will take off from Rocket Lab’s base in New Zealand. (submitted by Ken the Bin)

A rocket launch comes to Rizhao. China has diversified its launch sector over the last decade to include new families of small satellite launchers and new spaceports. One of these relatively new small rockets, the solid-fueled Ceres 1, took off Wednesday from a floating launch pad positioned about 2 miles (3 km) off the coast of Rizhao, a city of roughly 3 million people in China’s Shandong province. The Ceres 1 rocket, developed by a quasi-commercial company called Galactic Energy, has previously flown from land-based launch pads and a sea-borne platform, but this mission originated from a location remarkably close to shore, with the skyline of a major metropolitan area as a backdrop.

Range safety … There’s no obvious orbital mechanics reason to position the rocket’s floating launch platform so near a major Chinese city, other than perhaps to gain a logistical advantage by launching close to port. The Ceres 1 rocket has a fairly good reliability record—11 successes in 12 flights—but for safety reasons, there’s no Western spaceport that would allow members of the public (not to mention a few million) to get so close to a rocket launch. For decades, Chinese rockets have routinely dropped rocket boosters containing toxic propellant on farms and villages downrange from the country’s inland spaceports.

US officials: A Russian rocket launch last week likely deployed a space weapon

“Naming space as a warfighting domain was kind of forbidden, but that’s changed.”

The launch of a classified Russian military satellite last week deployed a payload that US government officials say is likely a space weapon.

In a series of statements, US officials said the new military satellite, named Kosmos 2576, appears to be similar to two previous “inspector” spacecraft launched by Russia in 2019 and 2022.

“Just last week, on May 16, Russia launched a satellite into low-Earth orbit that the United States assesses is likely a counter-space weapon presumably capable of attacking other satellites in low-Earth orbit,” said Robert Wood, the deputy US ambassador to the United Nations. “Russia deployed this new counter-space weapon into the same orbit as a US government satellite.”

Kosmos 2576 is flying in the same orbital plane as a National Reconnaissance Office (NRO) spy satellite, meaning it can regularly approach the top-secret US reconnaissance platform. The launch of Kosmos 2576 from Russia’s Plesetsk Cosmodrome on a Soyuz rocket was precisely timed to happen when the Earth’s rotation brought the launch site underneath the orbital path of the NRO spy satellite, officially designated USA 314.

The Soyuz rocket’s Fregat upper stage released Kosmos 2576 into an orbit roughly 275 miles (445 km) above Earth at an inclination of 97.25 degrees to the equator.

Conventional but concerning

So far, Kosmos 2576 is nowhere near USA 314, a bus-size spacecraft believed to carry a powerful Earth-facing telescope to capture high-resolution images for use by US intelligence agencies. This type of spacecraft is publicly known as a KH-11, or Keyhole-class, satellite, but its design and capabilities are top-secret.

It’s no surprise that the Russian military wants to get a close look in hopes of learning more about the US government’s most closely held secrets about what it does in orbit. Russian satellites have also flown near Western communications satellites in geostationary orbit, likely in an attempt to eavesdrop on radio transmissions.

Russia’s deputy foreign minister, Sergei Ryabkov, dismissed the US government’s assessment about the purpose of Kosmos 2576 as “fake news.” However, in the last few years, Russia has steered satellites into orbits intersecting with the paths of US spy platforms, and demonstrated it can take out an enemy satellite using a range of methods.

The current orbit of Kosmos 2576 will only occasionally bring it within a few hundred kilometers of the USA 314, according to Jonathan McDowell, an astrophysicist and expert tracker of spaceflight events. However, analysts expect additional maneuvers to raise the altitude Kosmos 2576 and put it into position for closer passes. This is what happened with a pair of Russian satellites launched in 2019 and 2022.

These two previous Russian satellites—Kosmos 2542 and Kosmos 2558— continually flew within a few dozen kilometers of two other NRO satellites—USA 245 and USA 326—in low-Earth orbit. In a post on the social media platform X, McDowell wrote that the Russian military craft “shadowed US satellites at a large distance but have not interfered with them.”

Because of this, McDowell wrote that he is “highly skeptical” that Kosmos 2576 is an anti-satellite weapon.

But one of these Russian satellites, Kosmos 2542, released a smaller sub-satellite, designated Kosmos 2543, which made its own passes near the USA 245 spacecraft, a KH-11 imaging satellite similar to USA 314. At one point, satellite trackers noticed USA 245 made a slight change to orbit. Its Russian pursuer later made a similar orbit adjustment to keep up.

In 2020, Kosmos 2543 backed off from USA 245. Once well away from the NRO satellite, Kosmos 2543 ejected a mysterious projectile into space at a speed fast enough to damage any target in its sights.

At the time, US Space Command called the event a “non-destructive test of a space-based anti-satellite weapon.” The projectile fired from Kosmos 2543 at a relative velocity of some 400 mph (700 km per hour), according to McDowell’s analysis of publicly available satellite tracking data.

Gen. Charles

Enlarge / Gen. Charles “CQ” Brown, chairman of the joint chiefs of staff, says the US military must have an ability to defend itself in space.

The US military has identified China as its most significant strategic adversary in the coming decades. Most aspects of Russia’s space program are in decline, but it still boasts formidable anti-satellite capabilities. Russia intentionally destroyed one of its retired satellites in orbit with a ground-based missile in 2021. The Russian military has also deployed several Peresvet laser units capable of disabling a satellite in orbit. A Russian cyberattack at the start of the invasion of Ukraine in 2022 knocked a commercial satellite communications network offline.

Most recently, US government officials have claimed Russia is developing a nuclear anti-satellite weapon. Russian officials also denied this. But Russia vetoed a UN Security Council resolution last month reiterating language from the 1967 Outer Space Treaty banning weapons of mass destruction in orbit.

The US military has its own fleet of inspector satellites in orbit to track what other nations are doing in space. The Space Force’s development of any offensive military capability in space is classified.

“The space domain is much more challenging today than it was a number a number of years ago,” said Air Force Gen. Charles “CQ” Brown, chairman of the joint chiefs of staff, in an event Wednesday hosted by the Atlantic Council. “We looked at it as a very benign environment, where you didn’t have to worry about conflicts in space. As a matter of fact, naming space as a warfighting domain was kind of forbidden, but that’s changed, and it’s been changed based what our adversaries are doing in space.”

“We don’t want to have our satellites … be challenged,” Brown said. “So we want to make sure that we have the capabilities to defend ourselves, no matter what domain we’re in, whether it’s in the space domain, air, land, or maritime. That’s where our focus is as a military, in making sure we’re investing to provide the capabilities and expertise to do that.”

“I lied” —

More than 60 years after he was denied an opportunity to become America’s first Black astronaut, Ed Dwight finally traveled into space Sunday with five other passengers on a 10-minute flight inside a Blue Origin capsule.

Dwight, a retired Air Force captain and test pilot, had a chance to become the first African American astronaut. He was one of 26 pilots the Air Force recommended to NASA for the third class of astronauts in 1963, but the agency didn’t select him. It took another 20 years for America’s first Black astronaut, Guion Bluford, to fly in space in 1983.

“Everything they did, I did, and I did it well,” Dwight said in a video released by Blue Origin. “If politics had changed, I would have gone to space in some kind of capacity.”

At the age of 90, Dwight finally entered the record books Sunday, becoming the oldest person to reach space, displacing the previous record-holder, actor William Shatner, who flew on a similar Blue Origin launch to the edge of space in 2021.

“I thought I didn’t need it in my life,” Dwight said after Sunday’s fight. “But I lied!”

Since retiring from the Air Force, Dwight became an accomplished sculptor. His works, which focus on Black history, are installed at memorials and monuments across the country.

“The transitions, the separations and stuff were a little bit more dynamic than I thought,” Dwight said in remarks after Sunday’s flight. “But that’s how it’s supposed to be. It makes your mind wonder, ‘Is something wrong?’ But no, it was absolutely terrific and the view … absolutely fantastic. This was a life-changing experience. Everybody needs to do this.”

Dwight and his five co-passengers lifted off from Blue Origin’s remote launch site in West Texas at 9: 35 am CDT (14: 35 UTC). Strapped into reclining seats inside a pressurized capsule, the passengers rode Blue Origin’s New Shepard rocket into the uppermost layers of the atmosphere. After burning its main engine more than two minutes, the rocket released the crew capsule and continued coasting upward to an apogee, or high point, of nearly 66 miles (107 kilometers), just above the internationally recognized boundary of space.

This was the seventh time Blue Origin, the space company owned by billionaire Jeff Bezos, has flown people to suborbital space, and the 25th flight overall of the company’s fleet of New Shepard rockets. It was the first time Blue Origin has launched people in nearly two years, resuming suborbital service after a rocket failure on an uncrewed research flight in September 2022. In December, Blue Origin launched another uncrewed suborbital research mission to set the stage for the resumption of human missions Sunday.

Joining Dwight on Blue Origin’s capsule were investor Mason Angel, French businessman Sylvain Chiron, software engineer Kenneth Hess, adventurer Carol Schaller, and Gopi Thotakura, an Indian pilot and entrepreneur. Dwight’s ticket with Blue Origin was sponsored by Space for Humanity, a nonprofit that seeks to expand access to space for all people, and the other five participants were paying passengers.

After cutoff of the New Shepard rocket engine, the passengers had a few minutes to unfasten their seatbelts and float around the cabin while taking in the view of Earth. They returned to their seats as the capsule descended back into the atmosphere. The reusable New Shepard booster reignited its main engine for a propulsive landing back in Texas, while the crew capsule deployed parachutes to slow for touchdown a few miles away.

Two of three

However, one of the three main parachutes did not fully unfurl as the capsule drifted back to the ground. The capsule is designed to safely land with two chutes, a capability Blue Origin demonstrated on a test flight in 2016.

“It looks like we do have two parachutes that have full inflation, the third is not quite fully inflated,” said Ariane Cornell, a Blue Origin official hosting the company’s live webcast Sunday. “Landing with two parachutes is perfectly OK for this system.”

Family members and Blue Origin personnel greeted the passengers as they exited the capsule. All six appeared to be in good spirits and good health.

Although it had no obvious ill effects on the crew or the spacecraft, Blue Origin engineers will investigate the malfunction to determine what went wrong. The capsule’s three main parachutes were supplied to Blue Origin by Airborne Systems, which manufactures parachutes for every US human-rated spacecraft.

One of the three main parachutes on Blue Origin's crew capsule did not fully inflate before landing.

Airborne also provides parachutes for SpaceX’s Dragon spacecraft, Boeing’s Starliner, and NASA’s Orion capsule. Those parachutes have different designs and sizes than the chutes used on Blue Origin’s capsule, but it wasn’t immediately clear if there might be any crossover concerns on other programs stemming from the malfunction on Sunday’s flight.

The Federal Aviation Administration, the regulatory agency that oversees US commercial space missions, said in a statement it did not consider the parachute issue a mishap. This statement suggests the incident will not trigger a mishap investigation that would require FAA oversight.

Before the 2022 launch failure, Blue Origin’s New Shepard program achieved a cadence, on average, of roughly one flight every two months. Virgin Galactic, the space tourism company founded by Richard Branson, ramped up the flight rate of its suborbital SpaceShipTwo spaceplane over the last year as Blue Origin’s rocket remained grounded.

But Virgin Galactic is about to halt operations of its own spaceship following one more flight with passengers next month. The company says it decided to suspend flights of the VSS Unity rocket plane to focus its resources on developing a fleet of larger air-launched spaceships that are easier to reuse.

This means Blue Origin, assuming it can regain or build on the cadence it demonstrated in 2021 and 2022, will be the only company serving the suborbital space tourism and research market for at least the next couple of years.

We take a stab at decoding SpaceX’s ever-changing plans for Starship in Florida

Enlarge / SpaceX’s Starship tower (left) at Launch Complex 39A dwarfs the launch pad for the Falcon 9 rocket (right).

There are a couple of ways to read the announcement from the Federal Aviation Administration that it’s kicking off a new environmental review of SpaceX’s plan to launch the most powerful rocket in the world from Florida.

The FAA said on May 10 that it plans to develop an Environmental Impact Statement (EIS) for SpaceX’s proposal to launch Starships from NASA’s Kennedy Space Center in Florida. The FAA ordered this review after SpaceX updated the regulatory agency on the projected Starship launch rate and the design of the ground infrastructure needed at Launch Complex 39A (LC-39A), the historic launch pad once used for Apollo and Space Shuttle missions.

Dual environmental reviews

At the same time, the US Space Force is overseeing a similar EIS for SpaceX’s proposal to take over a launch pad at Cape Canaveral Space Force Station, a few miles south of LC-39A. This launch pad, designated Space Launch Complex 37 (SLC-37), is available for use after United Launch Alliance’s last Delta rocket lifted off there in April.

On the one hand, these environmental reviews often take a while and could cloud Elon Musk’s goal of having Starship launch sites in Florida ready for service by the end of 2025. “A couple of years would not be a surprise,” said George Nield, an aerospace industry consultant and former head of the FAA’s Office of Commercial Space Transportation.

Another way to look at the recent FAA and Space Force announcements of pending environmental reviews is that SpaceX finally appears to be cementing its plans to launch Starship from Florida. These plans have changed quite a bit in the last five years.

The environmental reviews will culminate in a decision on whether to approve SpaceX’s proposals for Starship launches at LC-39A and SLC-37. The FAA will then go through a separate licensing process, similar to the framework used to license the first three Starship test launches from South Texas.

NASA has contracts with SpaceX worth more than $4 billion to develop a human-rated version of Starship to land astronauts on the Moon on the first two Artemis lunar landing flights later this decade. To do that, SpaceX must stage a fuel depot in low-Earth orbit to refuel the Starship lunar lander before it heads for the Moon. It will take a series of Starship tanker flights—perhaps 10 to 15—to fill the depot with cryogenic propellants.

Launching that many Starships over the course of a month or two will require SpaceX to alternate between at least two launch pads. NASA and SpaceX officials say the best way to do this is by launching Starships from one pad in Texas and another in Florida.

Earlier this week, Ars spoke with Lisa Watson-Morgan, who manages NASA’s human-rated lunar lander program. She was at Kennedy Space Center this week for briefings on the Starship lander and a competing lander from Blue Origin. One of the topics, she said, was the FAA’s new environmental review before Starship can launch from LC-39A.

“I would say we’re doing all we can to pull the schedule to where it needs to be, and we are working with SpaceX to make sure that their timeline, the EIS timeline, and NASA’s all work in parallel as much as we can to achieve our objectives,” she said. “When you’re writing it down on paper just as it is, it looks like there could be some tight areas, but I would say we’re collectively working through it.”

Officially, SpaceX plans to perform a dress rehearsal for the Starship lunar landing in late 2025. This will be a full demonstration, with refueling missions, an uncrewed landing of Starship on the lunar surface, then a takeoff from the Moon, before NASA commits to putting people on Starship on the Artemis III mission, currently slated for September 2026.

So you can see that schedules are already tight for the Starship lunar landing demonstration if SpaceX activates launch pads in Florida late next year.

Welcome to Edition 6.44 of the Rocket Report! Kathy Lueders, general manager of SpaceX’s Starbase launch facility, says the company expects to receive an FAA launch license for the next Starship test flight shortly after Memorial Day. It looks like this rocket could fly in late May or early June, about two-and-a-half months after the previous Starship test flight. This is an improvement over the previous intervals of seven months and four months between Starship flights.

Blue Origin launch on tap this weekend. Blue Origin plans to launch its first human spaceflight mission in nearly two years on Sunday. This flight will launch six passengers on a flight to suborbital space more than 60 miles (100 km) over West Texas. Blue Origin, Jeff Bezos’s space company, has not flown people to space since a New Shepard rocket failure on an uncrewed research flight in September 2022. The company successfully launched New Shepard on another uncrewed suborbital mission in December.

Historic flight … This will be the 25th flight of Blue Origin’s New Shepard rocket, and the seventh human spaceflight mission on New Shepard. Before Blue Origin’s rocket failure in 2022, the company was reaching a flight cadence of about one launch every two months, on average. The flight rate has diminished since then. Sunday’s flight is important not only because it marks the resumption of launches for Blue Origin’s suborbital human spaceflight business, but also because its six-person crew includes an aviation pioneer. Ed Dwight, 90, almost became the first Black astronaut in 1963. Dwight, a retired Air Force captain, piloted military fighter jets and graduated test pilot school, following a familiar career track as many of the early astronauts. He was on a short list of astronaut candidates the Air Force provided NASA, but the space agency didn’t include him. Dwight will become the oldest person to ever fly in space.

Spaceport Camden is officially no more. With the stroke of a pen, Georgia Governor Brian Kemp signed a bill that dissolved the Camden County Spaceport Authority, Action News Jax reported. This news follows a referendum in March 2022 where more than 70 percent of voters rejected a plan to buy land for the spaceport on the Georgia coastline between Savannah and Jacksonville, Florida. County officials still tried to move forward with the spaceport initiative after the failed referendum, but Georgia’s Supreme Court ruled in February that the county had to abide by the voters’ wishes.

$12 million for what?… The government of Camden County, with a population of about 55,000 people spent $12 million on the Spaceport Camden concept over the course of a decade. The goal of the spaceport authority was to lure small launch companies to the region, but no major launches ever took place from Camden County. State Rep. Steven Sainz, who sponsored the bill eliminating the spaceport authority, said in a statement that the legislation “reflects the community’s choice and opens a path for future collaborations in economic initiatives that are more aligned with local needs.” (submitted by zapman987)

Polaris Spaceplanes moves on to bigger things. German startup Polaris Spaceplanes says it is progressing with construction of its MIRA II and MIRA III spaceplane prototypes after MIRA, a subscale test vehicle, was damaged earlier this year, European Spaceflight reports. The MIRA demonstration vehicle crash-landed on a test flight in February. The incident occurred on takeoff at an airfield in Germany before the vehicle could ignite its linear aerospace engine in flight. The remote-controlled MIRA prototype measured about 4.25 meters long. Polaris announced on April 30 that will not repair MIRA and will instead move forward with the construction of a pair of larger vehicles.

Nearly 16 months without a launch … The MIRA II and MIRA III vehicles will be 5 meters long and will be powered by Polaris’s AS-1 aerospike engines, along with jet engines to power the craft before and after in-flight tests of the rocket engine. Aerospike engines are rocket engines that are designed to operate efficiently at all altitudes. The MIRA test vehicles are precursors to AURORA, a multipurpose spaceplane and hypersonic transporter Polaris says will be capable of delivering up to 1,000 kilograms of payload to low-Earth orbit.

Welcome to Edition 6.42 of the Rocket Report! Several major missions are set for launch in the next few months. These include the first crew flight on Boeing’s Starliner spacecraft, set for liftoff on May 6, and the next test flight of SpaceX’s Starship rocket, which could happen before the end of May. Perhaps as soon as early summer, SpaceX could launch the Polaris Dawn mission with four private astronauts, who will perform the first fully commercial spacewalk in orbit. In June or July, Europe’s new Ariane 6 rocket is slated to launch for the first time. Rest assured, Ars will have it all covered.

German rocket arrives at Scottish spaceport. Rocket Factory Augsburg has delivered a booster for its privately developed RFA One rocket to SaxaVord Spaceport in Scotland, the company announced on X. The first stage for the RFA One rocket was installed on its launch pad at SaxaVord to undergo preparations for a static fire test. The booster arrived at the Scottish launch site with five of its kerosene-fueled Helix engines. The remaining four Helix engines, for a total of nine, will be fitted to the RFA One booster at SaxaVord, the company said.

Aiming to fly this year… RFA hopes to launch its first orbital-class rocket by the end of 2024. The UK’s Civil Aviation Authority last month granted a range license to SaxaVord Spaceport to allow the spaceport operator to control the sea and airspace during a launch. RFA is primarily privately funded but has won financial support from the European Space Agency, the UK Space Agency, and the German space agency, known as DLR. The RFA One rocket will have three stages, stand nearly 100 feet (30 meters) tall, and can carry nearly 2,900 pounds (1,300 kilograms) of payload into a polar Sun-synchronous orbit.

Arianespace wins ESA launch contract. The European Space Agency has awarded Arianespace a contract to launch a joint European-Chinese space science satellite in late 2025, European Spaceflight reports. The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a 4,850-pound (2,200-kilogram) spacecraft that will study Earth’s magnetic environment on a global scale. The aim of the mission is to build a more complete understanding of the Sun-Earth connection. On Tuesday, ESA officially signed a contract for Arianespace to launch SMILE aboard a Vega C rocket, which is built by the Italian rocket-maker Avio.

But it may not keep it … In late 2023, ESA member states agreed to allow Avio to market and manage the launch of Vega C flights independent of Arianespace. When the deal was initially struck, 17 flights were contracted through Arianespace to be launched aboard Vega vehicles. While these missions are still managed by Arianespace, Avio is working with the launch provider to strike a deal that would allow the Italian rocket builder to assume the management of all Vega flights. The Vega C rocket has been grounded since a launch failure in 2022 forced Avio to redesign the nozzle of the rocket’s solid-fueled second-stage motor.

Update on ABL’s second launch. ABL Space Systems expected to launch its second light-class RS1 rocket earlier this year, but the company encountered an anomaly during ground testing at the launch site in Alaska, according to Aria Alamalhodaei of TechCrunch. Kevin Sagis, ABL’s chief engineer, said there is “no significant delay” in the launch of the second RS1 rocket, but the company has not announced a firm schedule. “During ground testing designed to screen the vehicle for flight, an issue presented that caused us to roll back to the hangar,” Sagis said, according to Alamalhodaei. “We have since resolved and dispositioned the issue. There was no loss of hardware and we have validated vehicle health back out on the pad. We are continuing with preparations for static fire and launch.”

Nearly 16 months without a launch … ABL’s first RS1 test flight in January 2023 ended seconds after liftoff with the premature shutdown of its liquid-fueled engines. The rocket crashed back onto its launch pad in Alaska. An investigation revealed a fire in the aft end of the RS1 booster burned through wiring harnesses, causing the rocket to lose power and shut off its engines. Engineers believe the rocket’s mobile launch mount was too small, placing the rocket too close to the ground when it ignited its engines. This caused the hot engine exhaust to recirculate under the rocket and led to a fire in the engine compartment as it took off.
