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.

“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.

The war of words between SpaceX and the FAA keeps escalating

Elon Musk, SpaceX's founder and CEO, has called for the resignation of the FAA administrator.

Enlarge / Elon Musk, SpaceX’s founder and CEO, has called for the resignation of the FAA administrator.

The clash between SpaceX and the Federal Aviation Administration escalated this week, with Elon Musk calling for the head of the federal regulator to resign after he defended the FAA’s oversight and fines levied against the commercial launch company.

The FAA has said it doesn’t expect to determine whether to approve a launch license for SpaceX’s next Starship test flight until late November, two months later than the agency previously communicated to Musk’s launch company. Federal regulators are reviewing changes to the rocket’s trajectory necessary for SpaceX to bring Starship’s giant reusable Super Heavy booster back to the launch pad in South Texas. This will be the fifth full-scale test flight of Starship but the first time SpaceX attempts such a maneuver on the program.

This week, SpaceX assembled the full Starship rocket on its launch pad at the company’s Starbase facility near Brownsville, Texas. “Starship stacked for Flight 5 and ready for launch, pending regulatory approval,” SpaceX posted on X.

Apart from the Starship regulatory reviews, the FAA last week announced it is proposing more than $633,000 in fines on SpaceX due to alleged violations of the company’s launch license associated with two flights of the company’s Falcon 9 rocket from Florida. It is rare for the FAA’s commercial spaceflight division to fine launch companies.

Michael Whitaker, the FAA’s administrator, discussed the agency’s ongoing environmental and safety reviews of SpaceX’s Starship rocket in a hearing before a congressional subcommittee in Washington Tuesday. During the hearing, which primarily focused on the FAA’s oversight of Boeing’s commercial airplane business, one lawmaker asked Whitaker the FAA’s relationship with SpaceX.

Public interest

“I think safety is in the public interest and that’s our primary focus,” said Michael Whitaker, the FAA administrator, in response to questions from Rep. Kevin Kiley, a California Republican. “It’s the only tool we have to get compliance on safety matters,” he said, referring to the FAA’s fines.

The stainless-steel Super Heavy booster is larger than a Boeing 747 jumbo jet. SpaceX says the flight path to return the first stage of the rocket to land will mean a “slightly larger area could experience a sonic boom,” and a stainless-steel ring that jettisons from the top of the booster, called the hot-staging ring, will fall in a different location in the Gulf of Mexico just offshore from the rocket’s launch and landing site.

The FAA, which is primarily charged with ensuring rocket launches don’t endanger the public, is consulting with other agencies on these matters, along with issues involving SpaceX’s discharge of water into the environment around the Starship launch pad in Texas. The pad uses water to cool a steel flame deflector that sits under the 33 main engines of Starship’s Super Heavy booster.

SpaceX says fines levied against it this year by the Texas Commission on Environmental Quality (TCEQ) and the Environmental Protection Agency (EPA) related to the launch pad’s water system were “entirely tied to disagreements over paperwork” and not any dumping of pollutants into the environment around the Starship launch site.

SpaceX installed the water-cooled flame deflector under the Starship launch mount after the engine exhaust rocket’s first test flight excavated a large hole in the ground. Gwynne Shotwell, SpaceX’s president and chief operating officer, summed up her view of the issue in a hearing with Texas legislators in Austin on Tuesday.

“To protect that from happening again, we built this kind of upside-down shower head to basically cool the flame as the rocket was lifting off,” she said. “That was licensed and permitted by TCEQ. The EPA came in afterwards and didn’t like the license or the permit that we had for that, and wanted to turn it into a federal permit, which we are working on now.”

“We work very closely with organizations such as TCEQ,” Shotwell said. “You may have read a little bit of nonsense in the papers recently about that, but we’re working quite well with them.”

SpaceX

This is an excerpt from Chapter 11 of the book REENTRY: SpaceX, Elon Musk and the Reusable Rockets that Launched a Second Space Age by our own Eric Berger. The book will be published on September 24, 2024. This excerpt describes a fateful meeting 10 years ago at NASA Headquarters in Washington, DC, where the space agency’s leaders met to decide which companies should be awarded billions of dollars to launch astronauts into orbit.

In the early 2010s, NASA’s Commercial Crew competition boiled down to three players: Boeing, SpaceX, and a Colorado-based company building a spaceplane, Sierra Nevada Corporation. Each had its own advantages. Boeing was the blue blood, with decades of spaceflight experience. SpaceX had already built a capsule, Dragon. And some NASA insiders nostalgically loved Sierra Nevada’s Dream Chaser space plane, which mimicked the shuttle’s winged design.

This competition neared a climax in 2014 as NASA prepared to winnow the field to one company, or at most two, to move from the design phase into actual development. In May of that year Musk revealed his Crew Dragon spacecraft to the world with a characteristically showy event at the company’s headquarters in Hawthorne. As lights flashed and a smoke machine vented, Musk quite literally raised a curtain on a black-and-white capsule. He was most proud to reveal how Dragon would land. Never before had a spacecraft come back from orbit under anything but parachutes or gliding on wings. Not so with the new Dragon. It had powerful thrusters, called SuperDracos, that would allow it to land under its own power.

“You’ll be able to land anywhere on Earth with the accuracy of a helicopter,” Musk bragged. “Which is something that a modern spaceship should be able to do.”

A few weeks later I had an interview with John Elbon, a long-time engineer at Boeing who managed the company’s commercial program. As we talked, he tut-tutted SpaceX’s performance to date, noting its handful of Falcon 9 launches a year and inability to fly at a higher cadence. As for Musk’s little Dragon event, Elbon was dismissive.

“We go for substance,” Elbon told me. “Not pizzazz.”

Elbon’s confidence was justified. That spring the companies were finalizing bids to develop a spacecraft and fly six operational missions to the space station. These contracts were worth billions of dollars. Each company told NASA how much it needed for the job, and if selected, would receive a fixed price award for that amount. Boeing, SpaceX, and Sierra Nevada wanted as much money as they could get, of course. But each had an incentive to keep their bids low, as NASA had a finite budget for the program. Boeing had a solution, telling NASA it needed the entire Commercial Crew budget to succeed. Because a lot of decision-makers believed that only Boeing could safely fly astronauts, the company’s gambit very nearly worked.

Scoring the bids

The three competitors submitted initial bids to NASA in late January 2014, and after about six months of evaluations and discussions with the “source evaluation board,” submitted their final bids in July. During this initial round of judging, subject-matter experts scored the proposals and gathered to make their ratings. Sierra Nevada was eliminated because their overall scores were lower, and the proposed cost not low enough to justify remaining in the competition. This left Boeing and SpaceX, with likely only one winner.

“We really did not have the budget for two companies at the time,” said Phil McAlister, the NASA official at the agency’s headquarters in Washington overseeing the Commercial Crew program. “No one thought we were going to award two. I would always say, ‘One or more,’ and people would roll their eyes at me.”

The members of the evaluation board scored the companies based on three factors. Price was the most important consideration, given NASA’s limited budget. This was followed by “mission suitability,” and finally, “past performance.” These latter two factors, combined, were about equally weighted to price. SpaceX dominated Boeing on price.

Boeing asked for $4.2 billion, 60 percent more than SpaceX’s bid of $2.6 billion. The second category, mission suitability, assessed whether a company could meet NASA’s requirements and actually safely fly crew to and from the station. For this category, Boeing received an “excellent” rating, above SpaceX’s “very good.” The third factor, past performance, evaluated a company’s recent work. Boeing received a rating of “very high,” whereas SpaceX received a rating of “high.”

While this makes it appear as though the bids were relatively even, McAlister said the score differences in mission suitability and past performance were, in fact, modest. It was a bit like grades in school. SpaceX scored something like an 88, and got a B; whereas Boeing got a 91 and scored an A. Because of the significant difference in price, McAlister said, the source evaluation board assumed SpaceX would win the competition. He was thrilled, because he figured this meant that NASA would have to pick two companies, SpaceX based on price, and Boeing due to its slightly higher technical score. He wanted competition to spur both of the companies on.

NASA is ready to start buying Vulcan rockets from United Launch Alliance

Full stack —

The second test flight of the Vulcan rocket is scheduled for liftoff on October 4.

The first stage of ULA's second Vulcan rocket was raised onto its launch platform August 11 at Cape Canaveral Space Force Station, Florida.

Enlarge / The first stage of ULA’s second Vulcan rocket was raised onto its launch platform August 11 at Cape Canaveral Space Force Station, Florida.

United Launch Alliance is free to compete for NASA contracts with its new Vulcan rocket after a successful test flight earlier this year, ending a period where SpaceX was the only company competing for rights to launch the agency’s large science missions.

For several years, ULA was unable to bid for NASA launch contracts after the company sold all of its remaining Atlas V rockets to other customers, primarily for Amazon’s Project Kuiper Internet network. ULA could not submit its new Vulcan rocket, which will replace the Atlas V, for NASA to consider in future launch contracts until the Vulcan completed at least one successful flight, according to Tim Dunn, senior launch director at NASA’s Launch Services Program.

The Vulcan rocket’s first certification flight on January 8, called Cert-1, was nearly flawless, demonstrating the launcher’s methane-fueled BE-4 engines built by Blue Origin and an uprated twin-engine Centaur upper stage. A second test flight, known as Cert-2, is scheduled to lift off no earlier than October 4 from Cape Canaveral Space Force Station, Florida. Assuming the upcoming launch is as successful as the first one, the US Space Force aims to launch its first mission on a Vulcan rocket by the end of the year.

The Space Force has already booked 25 launches on ULA’s Vulcan rocket for military payloads and spy satellites for the National Reconnaissance Office. But these missions won’t launch until Vulcan completes its second test flight, clearing the way for the Space Force to certify ULA’s new rocket for national security missions.

Back in the game

NASA’s Launch Services Program (LSP) is responsible for selecting and overseeing launch providers for the agency’s robotic science missions. NASA’s near-term options for launching large missions include SpaceX’s Falcon 9 and Falcon Heavy rockets, ULA’s Vulcan, and Blue Origin’s New Glenn launcher.

However, only SpaceX’s rockets have been available for NASA bids since 2021, when ULA sold all of its remaining Atlas V rockets to Amazon. For example, ULA did not submit proposals for the launch of a GOES weather satellite or NASA’s Roman Space Telescope, two of the more lucrative launch contracts the agency has awarded in the last couple of years. NASA selected SpaceX’s Falcon Heavy, the only eligible rocket, for both missions.

This is a notable role reversal for SpaceX and ULA, a 50-50 joint venture between Boeing and Lockheed Martin that was the sole launch provider for large NASA science missions and military satellites for nearly a decade. SpaceX launched its first mission for NASA’s Launch Services Program in January 2016.

The situation changed with the first flight of the Vulcan rocket in January.

“They certainly demonstrated a huge success earlier this year flying Cert-1,” Dunn told Ars in an interview. “They needed a successful flight to then bid for future missions, so that allowed them to be in a position to bid on our missions.”

NASA has not yet formally certified the Vulcan rocket to launch one of the agency’s science missions, but that would not stop NASA from selecting Vulcan for a contract. Some of NASA’s next big science missions up for launch contract awards include the nuclear-powered Dragonfly mission to explore Saturn’s moon Titan and an asteroid-hunting telescope named NEO Surveyor.

The second Vulcan flight next month will move ULA’s rocket toward certification by the Space Force and NASA.

“A second Cert flight that will then demonstrate a few other capabilities of the rocket allows more data for our certification team that is working in concert with the US Space Force’s certification team,” Dunn said. “We’re doing a lot of shared, intergovernmental collaborations in the certification work, so it allows us all more data, more confidence in that launch vehicle to meet all the needs that we believe we will have in the coming decade-plus.”

Blue Origin’s New Glenn could also compete for contracts to launch NASA’s larger, more expensive missions after it completes at least one successful flight. Blue Origin is currently eligible for bids to launch NASA’s smaller missions, such as the ESCAPADE mission to Mars already assigned to New Glenn. NASA is willing to accept more risk for launching these types of lower-cost missions.

ULA capped off the assembly of its second Vulcan rocket at Cape Canaveral on Saturday when technicians lifted the launcher’s payload fairing atop Vulcan’s first-stage booster and Centaur upper stage. For its second launch, Vulcan will carry a dummy payload instead of a real satellite. The second Vulcan flight was initially supposed to launch Sierra Space’s first Dream Chaser spaceplane to the International Space Station, but Dream Chaser isn’t ready, and the Space Force is eager for ULA to get moving and finish the certification process.

The head of Space Systems Command, Lt. Gen. Philip Garrant, told Ars last week that he is “optimistic” ULA will be in a position to launch its first Space Force missions with the Vulcan rocket by the end of this year. ULA has already delivered Vulcan rocket parts for the next two missions to Cape Canaveral, but the Cert-2 launch needs to go off without a hitch.

“We’re working very closely with ULA on that, as well as the manifest for the following missions,” Garrant said. “All of the rocket parts are at the launch locations, ready to go, but clearly the priority is the certification flight and making sure that the launch vehicle is certified. But we are optimistic that we’re going to get those launches off.”

    Maxar Technologies

Late last week, Russia’s military planned to launch a Sarmat intercontinental ballistic missile (ICBM) on a test flight from the Plesetsk Cosmodrome. Imagery from commercial satellites captured over the weekend suggest the missile exploded before or during launch.

This is at least the second time an RS-28 Sarmat missile has failed in less than two years, dealing a blow to the country’s nuclear forces days after the head of the Russian legislature issued a veiled threat to use the missile against Europe if Western allies approved Ukraine’s use of long-range weapons against Russia.

Commercial satellite imagery collected by Maxar and Planet show before-and-after views of the Sarmat missile silo at Plesetsk, a military base about 500 miles (800 kilometers) north of Moscow. The view from one of Maxar’s imaging satellites Saturday revealed unmistakable damage at the launch site, with a large crater centered on the opening to the underground silo.

The crater is roughly 200 feet (62 meters) wide, according to George Barros, a Russia and geospatial intelligence analyst at the Institute for the Study of War. “Extensive damage in and around the launch pad can be seen which suggests that the missile exploded shortly after ignition or launch,” Barros wrote on X.

“Additionally, small fires continue to burn in the forest to the east of the launch complex and four fire trucks can be seen near the destroyed silo,” Barros added.

The Sarmat missile is Russia’s largest ICBM, with a height of 115 feet (35 meters). It is capable of delivering nuclear warheads to targets more than 11,000 miles (18,000 kilometers) away, making it the longest-range missile in the world. The three-stage missile burns hypergolic hydrazine and nitrogen tetroxide propellants, and is built by the Makeyev Design Bureau. The Sarmat, sometimes called the Satan II, replaces Russia’s long-range R-36M missile developed during the Cold War.

“According to Russian media, Sarmat can reportedly load up to 10 large warheads, 16 smaller ones, a combination of warheads and countermeasures, or hypersonic boost-glide vehicle,” the Center for Strategic and International Studies writes on its website.

The secret is out

Western analysts still don’t know exactly when the explosion occurred. Russia issued warnings last week for pilots to keep out of airspace along the flight path of a planned missile launch from the Plesetsk Cosmodrome. Russia published similar notices before previous Sarmat missile tests, alerting observers that another Sarmat launch was imminent. The warnings were canceled Thursday, two days before satellite imagery showed the destruction at the launch site.

“It is possible that the launch attempt was undertaken on September 19th, with fires persisting for more than 24 hours,” wrote Pavel Podvig, a senior researcher at the United Nations Institute for Disarmament Research in Geneva, on his Russian Nuclear Forces blog site. “Another possibility is that the test was scrubbed on the 19th and the incident happened during the subsequent defueling of the missile. The character of destruction suggests that the missile exploded in the silo.”

James Acton, a senior fellow at the Carnegie Endowment for International Peace, wrote on X that the before-and-after imagery of the Sarmat missile silo was “very persuasive that there was a big explosion.”

NASA has a fine plan for deorbiting the ISS—unless Russia gets in the way

NASA/Roscosmos

A little more than two years ago, Dmitry Rogozin, the bellicose former head of Russia’s space agency, nearly brought the International Space Station partnership to its knees.

During his tenure as director general of Roscosmos, Rogozin was known for his bombastic social media posts and veiled threats to abandon the space station after Russia’s invasion of Ukraine. Russian President Vladimir Putin tersely dismissed Rogozin in July 2022 and replaced him with Yuri Borisov, a former deputy prime minister.

While the clash between Russia and Western governments over the war in Ukraine has not cooled, the threats against the International Space Station (ISS) ended. The program remains one of the few examples of cooperation between the US and Russian governments. Last year, Russia formally extended its commitment to the ISS to at least 2028. NASA and space agencies in Europe, Japan, and Canada have agreed to maintain the space station through 2030.

It’s this two-year disparity that concerns NASA officials plotting the final days of the ISS. NASA awarded SpaceX a contract in June to develop a deorbit vehicle based on the company’s Dragon spacecraft to steer the more than 450-ton complex toward a safe reentry over a remote stretch of ocean.

“We do have that uncertainty, 2028 through 2030, with Roscosmos,” said Robyn Gatens, director of the ISS program at NASA Headquarters, in a meeting of the agency’s advisory council this week. “We expect to hear from them over the next year or two as far as their follow-on plans, hoping that they also extend through 2030.”

Fighting through the tension

Roscosmos works in four-year increments, so Russia’s decision last year extended the country’s participation in the space station program from 2024 until 2028. Russian space officials know the future of the country’s space program is directly tied to the ISS. If Russia pulls out of the space station in 2028, Roscosmos will be left without much of a human spaceflight program.

There’s no chance Russia will have its own space station in low-Earth orbit in four years, so abandoning its role on the ISS would leave Russia’s Soyuz crew ferry spacecraft without a destination. Russian and Chinese leaders have fostered closer ties in space in recent years, but China’s Tiangong space station is inaccessible from Russia’s launch sites.

The US and Russian segments of the ISS depend on one another for critical functions. The US section generates most of the space station’s electricity and maintains the lab’s orientation without using precious rocket fuel. Russia is responsible for maintaining the station’s altitude and maneuvering the complex out of the path of space junk, although Northrop Grumman’s Cygnus cargo craft has also demonstrated an ability to boost the station’s orbit.

While Russia’s space program would feel the pain if Roscosmos made an early exit from the space station, the relationship between Russia and the West is volatile. US and European leaders may soon give Ukraine the green light to use Western-supplied weapons for attacks deep inside Russian territory. Putin said last week that this would be tantamount to war. “This will mean that NATO countries, the United States, and European countries are fighting Russia,” he said.

Talking to the Moon —

“This has really been a transformational year for us.”

Intuitive Machines

One of the miracles of the Apollo Moon landings is that they were televised, live, for all the world to see. This transparency diffused doubts about whether the lunar landings really happened and were watched by billions of people.

However, as remarkable a technical achievement as it was to broadcast from the Moon in 1969, the video was grainy and black and white. As NASA contemplates a return to the Moon as part of the Artemis program, it wants much higher resolution video and communications with its astronauts on the lunar surface.

To that end, NASA announced this week that it had awarded a contract to Houston-based Intuitive Machines for “lunar relay services.” Essentially this means Intuitive Machines will be responsible for building a small constellation of satellites around the Moon that will beam data back to Earth from the lunar surface.

“One of the requirements is a 4K data link,” said Steve Altemus, co-founder and chief executive of Intuitive Machines, in an interview. “That kind of high fidelity data only comes from a data relay with a larger antenna than can be delivered to the surface of the Moon.”

About the plan

This is part of NASA’s plan to build a more robust “Near Space Network” for communications within 1 million miles of Earth (the Moon is about 240,000 miles from Earth). Intuitive Machines’ contract is worth as much as $4.82 billion over the next decade, depending on the level of communication services that NASA chooses to purchase.

The space agency is also expected to award a ground-based component of this network for large dishes to receive signals from near space, taking some of this burden off the Deep Space Network. Altemus said Intuitive Machines has also bid on this ground component contract.

The Houston company, with its IM-1 mission, made a largely successful landing on the Moon in February. A second lunar landing mission, IM-2, is scheduled to take place in late December or January, a few months from now. Funded largely by NASA, the IM-2 mission will carry a small drill to the South Pole of the Moon to search for water ice in Shackleton Crater.

Then, approximately 15 months from now, the company is planning to launch another lander, IM-3. This mission is likely to carry the first data-relay satellite—each is intended to be about 500 kg, Altemus said, but the final design of the vehicles is still being finalized—to lunar orbit. Assuming this first satellite works well, the two following IM missions will each carry two relay satellites, making for a constellation of five spacecraft orbiting the Moon.

Two of the satellites will go into polar orbits and serve NASA’s Artemis needs at the South Pole, Altemus said. Two more are likely to go into halo orbits, and a fifth satellite will be placed into an equatorial orbit. This will provide full coverage of the Moon not just for communications, but also for position, navigation, and timing.

Intuitive Machines rising

A former deputy director of Johnson Space Center, Altemus founded Intuitive Machines in 2013 along with an investor, Kam Ghaffarian, and an aerospace engineer named Tim Crain. It hasn’t always been easy. Development of Intuitive Machines’ Nova C lander took years longer than anticipated; there were setbacks such as a propellant tank failure, and money was at times tight.

In part to address these financial difficulties, the company went public in 2023, at the tail end of the mania in which space companies were becoming publicly traded via special purpose acquisition companies, or SPACs. Many space companies that went public this way have struggled mightily, and Intuitive Machines has also faced similar pressures.

“It’s been a challenge,” Altemus said. “We went public in 2023, and navigating that was the story of last year, as well as getting to the launch pad.”

But then good things started happening. Despite some technical troubles, including the failure of its altimeter, the company’s first lander managed a soft touchdown on the Moon on its side. Even with this untinended orientation, the Intuitive Machines-1 mission still managed to complete the vast majority of its science objectives. In August, the company won its fourth task order from NASA—essentially a lunar delivery mission—under the Commercial Lunar Payload Services program.

And then the company won the massive data relay contract this week.

“This has really been a transformational year for us,” Altemus said. “The vision for the company is finally coming together.”

Station struggles —

“The business model had to change.”

Axiom Space

Axiom Space is facing significant financial headwinds as the company attempts to deliver on two key commercial programs for NASA—the development of a private space station in low-Earth orbit and spacesuits that could one day be worn by astronauts on the Moon.

Forbes reports that Axiom Space, which was founded by billionaire Kam Ghaffarian and NASA executive Mike Suffredini in 2016, has been struggling to raise money to keep its doors open and has had difficulties meeting its payroll dating back to at least early 2023. In addition, the Houston-based company has fallen behind on payments to key suppliers, including Thales Alenia Space for its space station and SpaceX for crewed launches.

“The lack of fresh capital has exacerbated long-standing financial challenges that have grown alongside Axiom’s payroll, which earlier this year was nearly 1,000 employees,” the publication reports. “Sources familiar with the company’s operations told Forbes that co-founder and CEO Michael Suffredini, who spent 30 years at NASA, ran Axiom like a big government program instead of the resource-constrained startup it really was. His mandate to staff up to 800 workers by the end of 2022 led to mass hiring so detached from product development needs that new engineers often found themselves with nothing to do.”

The report underscores a lot of what Ars has been hearing about the financial struggles of Axiom in recent months. Dozens of employees have been laid off, and Thales officials have made no secret of their discontent at not being paid in full for the production of pressure modules for the Axiom space station. Although the departure of Suffredini as chief executive was framed as being his decision for personal reasons, it seems probable that he moved out of the company for performance reasons.

Space station troubles

All of this raises significant questions about Axiom’s ability to deliver on the primary reason the company was created—to build a successor to the International Space Station. Suffredini joined Ghaffarian in the venture after serving as manager of NASA’s space station program for more than a decade. When they founded the company in 2016, the plan was to launch an initial space station module in 2020.

The timeline for station development has since been delayed multiple times. Presently, Axiom plans to launch its first module to the International Space Station no earlier than late 2026. And the company’s ambitions have been downsized, according to the report. Instead of a four-module station that would be separated from the government-operated space station by 2030, Axiom is likely to go forward with a smaller station consisting of just two elements. This station would have lower power and reduced commercial potential, according to the article.

“The business model had always counted on having significant power for microgravity research, semiconductor production, and pharmaceutical production, plus supporting life in space,” a source told the publication. “The business model had to change… and that has continued to make it challenging for the company to get around its cash flow issues.”

Axiom is one of several companies—alongside Blue Origin, Voyager Space, Vast Space, and potentially SpaceX—working with NASA to devise commercial replacements for the International Space Station after that facility retires in 2030.

NASA plans to issue a “request for proposals” for the second round of commercial space station contracts in 2025 and make an award the following year. Multiple sources have indicated that the space agency would like to award at least two companies in this second phase. However, Ghaffarian told Forbes that he would prefer NASA to decide next year and award a single competitor.

“Today there’s not enough market for more than one,” he said.

This may be true, although some of Axiom’s competitors may dispute it. Nevertheless, Ghaffarian’s desire for an award next year, and for a sole winner, underscores the evident urgency of Axiom’s fundraising needs.

Dragons and spacesuits

The report also notes that Axiom has lost significant amounts of funding on three private astronaut missions it has flown to the International Space Station to date. Ghaffarian said these missions were conducted at a loss to build relationships with global space agencies. This does make some sense, as space agencies in Europe, the Middle East, and elsewhere are likely to be customers of commercial space stations in the next decade. However, Axiom is ill-positioned to absorb such launches financially.

The publication reveals that Axiom is due to pay $670 million to SpaceX for four Crew Dragon missions, each of which includes a launch and ride for four astronauts to and from the station encompassing a one- to two-week period. This equates to $167.5 million per launch, or $41.9 million per seat.

Axiom’s other major line of business is a $228 million development contract with NASA to develop spacesuits for the Artemis Program, which will allow astronauts to venture outside the Starship lunar lander on the Moon’s surface. According to the Forbes report, this initiative has pulled resources away from the space station program.

Multiple sources have told Ars that, from a financial and technical standpoint, this spacesuit program is on better footing than the station program. And at this point, the spacesuit program is probably the one element of Axiom’s business that NASA views as essential going forward.

So what are we to make of the highly ambitious, private Polaris spaceflight?

Riding the Dragon —

They flew high, they walked in space, and finally early on Sunday, they landed.

A white spacecraft, lightly toasted like a marshmallow and smelling of singed metal, fell out of the night sky early on Sunday morning and splashed down in the Gulf of Mexico not all that far from Key West.

The darkened waters there were carefully chosen from among dozens of potential landing spots near Florida. This is because the wind and seas were predicted to be especially calm and serene as the Crew Dragon spacecraft named Resilience floated down to the sea and bobbed gently, awaiting the arrival of a recovery ship.

Inside waited a crew of four—Commander Jared Isaacman, a billionaire who funded the mission and had just completed his second private spaceflight; SpaceX engineers Sarah Gillis and Anna Menon, who were the company’s first employees to fly into orbit; and Pilot Kidd Poteet.

They were happy to be home.

“We are mission complete,” Isaacman said after the spacecraft landed.

A significant success

Their mission, certainly the most ambitious private spaceflight to date, was a total success. Named “Polaris Dawn,” the mission flew to an altitude of 1,408.1 km on the first day of the flight. This was the highest Earth-orbit mission ever flown, and the furthest humans have traveled from our planet since the Apollo missions more than half a century ago.

Then, on the third day of the flight, the four crew members donned spacesuits designed and developed within the last two years. After venting the cabin’s atmosphere into space, first Isaacman, and then Gillis, spent several minutes extending their bodies out of the Dragon spacecraft. This was the first-ever private spacewalk in history.

Although this foray into space largely repeated what the Soviet Union, and then the United States performed in the mid-1960s, with tethered spacewalks, it nonetheless was significant. These commercial spacesuits cost a fraction of government suits, and can be considered version 1.0 of suits that could one day enable many people to walk in space, on the Moon, and eventually Mars.

The crew of Polaris Dawn calls back to SpaceX's headquarters in Hawthrone, California, on Saturday.

SpaceX

Finally, on the mission’s final full day in space Saturday, the Dragon spacecraft demonstrated connectivity with a mesh of Starlink satellites in low-Earth orbit. The crew held a 40-minute, uninterrupted video call with flight operators back at SpaceX’s headquarters in Hawthorne, California. During that time, according to the company, Dragon maintained contact via laser links to Starlink satellites through 16 firings of the spacecraft’s Draco thrusters.

This test demonstrated the viability of using the thousands of Starlink satellites in orbit as a means of providing high-speed internet to people and spacecraft in space.

Wait, isn’t this just a billionaire joyride?

Some people have misunderstood the mission. They saw in Isaacman a financial tech billionaire gratifying his desire to go to space, inside a crew vehicle built by Elon Musk’s rocket company SpaceX. Thus, this appeared to be just a roller coaster ride for the ultra-rich and famous—for those who could not sate their thrill-seeking with the pleasures attainable on planet Earth.

I understand this viewpoint, but I do not share it.

The reality is that Isaacman and his hand-picked crew, which included two SpaceX employees who will take their learnings back to design spacecraft and other vehicles at the company, trained hard for this mission over the better part of two years. In flying such a daring profile to a high altitude through potential conjunctions with thousands of satellites; and then venting their cabin to perform a spacewalk, each of the crew members assumed high risks.

For its Crew Dragon missions that fly to and from the International Space Station, NASA has an acceptable “loss-of-crew” probability of 1-in-270. But in those spaceflights the crew spends significantly less time inside Dragon, and flies to a much lower and safer altitude. They do not conduct spacewalks out of Dragon. The crew of Polaris Dawn, therefore, assumed non-trivial dangers in undertaking this spaceflight. These risks assumed were measured rather than reckless.

So why? Why take such risks? Because the final frontier, after nearly seven decades of spaceflight, remains largely unexplored. If it is human destiny to one day expand to other worlds, and eventually other stars, we’re going to need to do so with more than few government astronauts making short sorties. To open space there must be lower cost access and commercial potential.

With his inventive and daring Polaris Dawn mission, Isaacman has taken a step toward such a future, by pushing forward the performance of Dragon, and accelerating SpaceX’s timeline to develop low-cost spacesuits. Certainly, Isaacman had a blast. But it was for a very good cause. He was lucky enough to go first, but through his actions, he aims to blaze a trail for multitudes to follow.

NASA astronauts Butch Wilmore and Suni Williams are no strangers to time away from their families. Both are retired captains in the US Navy, served in war zones, and are veterans of previous six-month stays on the International Space Station.

When they launched to the space station on Boeing’s Starliner spacecraft on June 5, the astronauts expected to be home in a few weeks, or perhaps a month, at most. Their minimum mission duration was eight days, but NASA was always likely to approve a short extension. Wilmore and Williams were the first astronauts to soar into orbit on Boeing’s Starliner spacecraft, a milestone achieved some seven years later than originally envisioned by Boeing and NASA.

However, the test flight fell short of all of its objectives. Wilmore and Williams are now a little more than three months into what has become an eight-month mission on the station. The Starliner spacecraft was beset by problems, culminating in a decision last month by NASA officials to send the capsules back to Earth without the two astronauts. Rather than coming home on Starliner, Wilmore and Williams will return to Earth in February on a SpaceX Dragon spacecraft.

Grateful for options

On Friday, the two astronauts spoke with reporters for the first time since NASA decided they would stay in orbit until early 2025.

“It was trying at times,” Wilmore said. There were some tough times all the way through. Certainly, as the commander or pilot of your spacecraft, you don’t want to see it go off without you, but that’s where we wound up.”

Both astronauts are veteran Navy test pilots and have previous flights on space shuttles and Russian Soyuz spacecraft. Captains never want to abandon ship, but that’s not what happened with Starliner. Instead, their ship left them.

Williams said she and Wilmore watched Starliner’s departure from the space station from the lab’s multi-window cupola module last week. They kept busy with several tasks, such as monitoring the undocking and managing the space station’s systems during the dynamic phase of the departure.

“We were watching our spaceship fly away at that point in time,” Williams said. “I think it’s good we had some extra activities. Of course, we’re very knowledgeable about Starliner, so it was obvious what was happening at each moment.”

NASA’s top managers did not have enough confidence in Starliner’s safety after five thrusters temporarily failed as the spacecraft approached the space station in June. They weren’t ready to risk the lives of the two astronauts on Starliner when engineers weren’t convinced the same thrusters, or more, would function as needed during the trip home.

It turned out the suspect thrusters on Starliner worked after it departed the space station and headed for reentry on September 6. One thruster on Starliner’s crew module—different in design from the thrusters that previously had trouble—failed on the return journey. Investigating this issue is something Boeing and NASA engineers will add to their to-do list before the next Starliner flight, alongside the earlier problems of overheating thrusters and helium leaks.

“It’s a very risky business, and things do not always turn out the way you want,” Wilmore said. “Every single test flight, especially a first flight of a spacecraft or aircraft that’s ever occurred, has found issues …  90 percent of our training is preparing for the unexpected, and sometimes the actual unexpected goes beyond what you even think that could happen.”

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

Nearly a decade ago to the day, I stood in the international terminal of Houston’s main airport checking my phone. As I waited to board a flight for Moscow, an announcement from NASA was imminent, with the agency due to make its selections for private companies that would transport astronauts to the International Space Station.

Then, just before boarding the direct flight to Moscow, a news release from NASA popped into my inbox about its Commercial Crew Program. The space agency, under a fixed price agreement, agreed to pay Boeing $4.2 billion to develop the Starliner spacecraft; SpaceX would receive $2.6 billion for the development of its Crew Dragon vehicle.

At the time, the Space Shuttle had been retired for three years, and NASA’s astronauts had to fly to the International Space Station aboard the Soyuz spacecraft. “Today, we are one step closer to launching our astronauts from US soil on American spacecraft and ending the nation’s sole reliance on Russia by 2017,” NASA Administrator Charles Bolden said in the release.

I knew this only too well. As the space reporter for the Houston Chronicle, I was traveling with NASA officials to Russia to visit Star City, where astronauts train, and see Roscosmos’ mission control facilities. From there, we flew to Kazakhstan to tour the spaceport in Baikonur and observe the launch of the Expedition 41 crew to the space station. The mission included two Russian astronauts and NASA’s Butch Wilmore. I wrote about this as the fifth part of my Adrift series on the state of America’s space program.

A decade later, it all seems surreal. I cannot imagine, as I did a decade ago, standing near soldiers in Moscow watching a “Peace March” of thousands of protestors through the Russian capital city. There is no room for dissent in Russia today. The airport we used to fly from Moscow to Kazakhstan, Domodedovo, has been attacked by Ukrainian drones. I almost certainly can never go back to Russia, especially after being branded a “war criminal” by the country’s space boss.

But history turns in interesting ways. Ten years after his Soyuz flight from Kazakhstan, Wilmore launched from Florida on Boeing’s Starliner spacecraft. Last weekend, this Boeing spacecraft came back to Earth without Wilmore and his copilot Suni Williams on board. Here we were once again: Wilmore flying in space and me thinking and writing about the future of NASA’s human spaceflight programs.

I couldn’t help but wonder: After all that happened in the last decade, has the Commercial Crew Program been a success?

Boeing becomes a no-show

Commercial Crew was a bold bet by NASA that won the space agency many critics. Could private companies really step up and provide a service that only nations had before?

NASA’s two selections, Boeing and SpaceX, did not make that 2017 target for their initial crewed flights. For a few years, Congress lagged in funding the program, and during the second half of the 2010s, each of the companies ran into significant technical problems. SpaceX overcame serious issues with its parachutes and an exploding spacecraft in 2019 to triumphantly reach orbit in the summer of 2020 with its Demo-2 mission, flying NASA astronauts Doug Hurley and Bob Behnken to and from the space station.

Since then, SpaceX has completed seven operational missions to the station, carrying astronauts from the United States, Europe, Japan, Russia, the Middle East, and elsewhere into orbit. A crew from the eighth mission is on the station right now, and the ninth Crew Dragon mission will launch later this month to bring Wilmore and Williams back to Earth. Crew Dragon has been nothing short of a smashing success for SpaceX and the United States, establishing a vital lifeline at a time when—amid deteriorating relations between America and Russia—NASA reliance on Soyuz likely would have been untenable.

Starliner has faced a more difficult road. Its first uncrewed test flight in late 2019 was cut short early after serious software problems. Afterward, NASA designated the flight as a “high visibility close call” and said Boeing would need to fly a second uncrewed test flight. This mission in 2022 was more successful, but lingering concerns and issues with flammable tape and parachutes delayed the first crew flight until June of this year. The fate of Starliner’s third flight this summer, and its intermittently failing thrusters that ultimately led to its crew needing an alternative ride back to Earth, has been well documented.
