Commander Jared Isaacman, the billionaire CEO of Shift4 Payments who purchased the five-day orbital flight from SpaceX, and mission specialist Sarah Gillis, one of two SpaceX engineers who are the company’s first employees to fly to space, exited SpaceX’s Dragon capsule one at a time, each spending about 12 minutes outside. The astronauts were traveling at 17,500 mph at an altitude more than 450 miles above Earth, higher than the International Space Station.

But there’s a catch. Because Dragon does not have an airlock, all four crewmembers were exposed to the vacuum of space. The mission profile added risk compared to a typical spacewalk, where astronauts enter and exit through a vacuum-sealed chamber.

“Today’s EVA was the first time four humans were exposed to the vacuum of space while completing the first-ever commercial astronaut spacewalk from a commercially-produced spacecraft in commercially-produced extravehicular activity [EVA] suits,” said Stu Keech, vice president of Dragon engineering at SpaceX.

SpaceX provided live stream coverage of the full, approximately two-hour process, which can be rewatched here.

The Falcon 9 rocket carrying Dragon and the Polaris Dawn crew lifted off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida early Tuesday morning. Almost immediately, the astronauts began preparing for the spacewalk.

The first step was a “prebreathe” to remove nitrogen bubbles that can form within body tissues, causing decompression sickness. During the approximately two-day process, the cabin’s pressure was lowered and oxygen levels were raised gradually to help the crew acclimate.

After that, the astronauts donned their EVA spacesuits, which are designed to be worn both inside and outside the spacecraft. Developed by SpaceX with help from Isaacman’s Polaris team, the suits have endured hundreds of hours of testing and feature greater mobility, durability, and even a high-tech heads-up display (HUD).

“Building a base on the moon and a city on Mars will require thousands of spacesuits,” SpaceX said in a post on X. “The development of this suit, and the EVA performed on this mission, will be important steps toward a scalable design for spacesuits on future long-duration missions.”

After completing suit leak checks and venting Dragon down to vacuum, Isaacman opened the hatch and was first to egress. Remaining attached to the spacecraft, he used a specially designed structure called Skywalker to move around and perform tests on the suit’s thermal and mobility systems. Skywalker is equipped with several cameras that were used to capture the moment in real time.

“SpaceX, back at home we all have a lot of work to do,” Isaacman said as he looked down on the planet below, “but from here, Earth sure looks like a perfect world.”

After Isaacman returned, it was Gillis’ turn. The SpaceX engineer stepped out and performed the same series of tests, while mission pilot Scott “Kidd” Poteet and mission specialist and medical officer Anna Menon monitored her support systems.

Finally, the hatch was closed, Dragon was repressurized, and the astronauts removed their suits.

“Dragon uses pure nitrogen during ‘repress,’ which mixes with the pure oxygen being released into the cabin via the open loop system that keeps the EVA suits pressurized,” SpaceX said. “This process is unique to Dragon which acts as its own airlock.”

From venting to repressurization, the entire process took about one hour and 45 minutes.

SpaceX CEO Elon Musk was quick to praise the crew for its historic achievement, as was NASA administrator Bill Nelson.

“Congratulations @PolarisProgram and @SpaceX on the first commercial spacewalk in history!” Nelson posted on X. “Today’s success represents a giant leap forward for the commercial space industry and @NASA’s long-term goal to build a vibrant U.S. space economy.”

Polaris Dawn, the first of three missions Isaacman purchased for SpaceX under the Polaris program, has so far lived up to its lofty expectations. In addition to the spacewalk, the astronauts on day two of the mission ascended to an orbital height not reached by humans since the Apollo 17 astronauts in 1972, passing through hazardous radiation belts. 

Menon also read a children’s book she authored, Kisses from Space, for her family and patients of St. Jude Children’s Research Hospital, live from orbit. While the Polaris missions are scientific—Polaris Dawn alone will conduct nearly 40 experiments—they are also billed as charitable endeavors to raise money for St. Jude.

Ultimately, the Polaris program may have a ripple effect on NASA’s efforts to return Americans to the moon via the Artemis program.

Polaris Mission III is expected to be the debut crewed flight of SpaceX’s Starship, the largest and most powerful rocket ever built. The space agency has asked the company to develop a lunar lander variant of Starship to land astronauts on the moon’s south pole, which will be used during Artemis III scheduled for September 2026.

This comes after a weeklong mission to the ISS extended into an eight-month nightmare for two astronauts after the Starliner experienced thruster malfunctions during the trip to space. Since their blastoff on June 5, NASA astronauts Barry “Butch” Wilmore and Sunita “Suni” Williams have been staying on the ISS alongside the Expedition 71 crew.

NASA announced in August that the crew would be returning via the SpaceX Dragon spacecraft in February. They won’t be the first astronauts returning to Earth in a separate spacecraft than the one they launched from, though missions extended from unforeseen factors are rare. 

Returning the Starliner

NASA’s mission timeline posted on Thursday states that safety and mission success remains top priorities for teams during the Starliner’s return.

As the first American capsule designed to touch down on land, the Starliner will use potential landing locations in the White Sands Missile Range, New Mexico; Willcox, Arizona; and Dugway Proving Ground, Utah. NASA said that Edwards Air Force Base in California is also available as a contingency landing site.

NASA said it analyzes weather predictions for the various landing sites, taking note of winds, ground temperatures, cloud ceiling height, visibility, precipitation, and nearby storms. When the teams start undocking, the Starliner will complete several departure burns. From there, the spacecraft is planned to reach its landing site in as little as six hours.

During this deorbit burn, a final weather check will commence.

“Winds must be at or below 10 mph (9 knots),” NASA’s mission timeline said. “If winds exceed these limits, teams will waive the deorbit burn, and Starliner will target another landing attempt between 24 and 31 hours later.”

Assuming weather meets acceptable conditions, Starliner will execute its deorbit burn for approximately 60 seconds. This will slow it down enough to reenter earth’s atmosphere and land at its target site. Immediately after the deorbit burn, the spacecraft will reposition for service module disposal, which will burn up during reentry over the southern Pacific Ocean.

Reentry will see the capsule reach temperatures of up to 3,000 degrees Fahrenheit, which may interrupt communications with the spacecraft for approximately four minutes. After this, the forward heat shield on top of the aircraft will be jettisoned and several parachutes will be deployed at 30,000 feet.

• READ MORE: NASA: Starliner Astronauts May Not Return Until February

As the aircraft continues to slow down, the base heat shield will jettison at 3,000 feet and cause six landing bags to inflate. The spacecraft will travel at approximately 4 mph at touchdown.

Recovery After Landing

After touchdown, several NASA and Boeing landing recovery teams stationed near Starliner’s landing site will move toward the spacecraft in sequential order:

• The gold team will use equipment to “sniff” the capsule for any hypergolic fuels that didn’t fully burn off before re-entry. They also cover the spacecraft’s thrusters.

• The silver team will then electrically ground and stabilize the Starliner.
• The green team will supply power and cooling to the crew module since the spacecraft will be powered down.
• The blue team will then document the recovery for public dissemination and future process review.
• The red team, which includes Boeing fire rescue, emergency medical technicians, and human factors engineers, then will open the Starliner hatch.

The teams will begin unloading time-critical cargo from the Starliner. The spacecraft will then be moved to Boeing facilities at NASA’s Kennedy Space Center in Florida for refurbishment.

The post NASA Reveals Mission Timeline for Crewless Starliner Return appeared first on FLYING Magazine.

The jets are owned by billionaire entrepreneur and Polaris Dawn commander Jared Isaacman, who purchased the five-day orbital mission and two other private astronaut flights from SpaceX in 2022. Among other feats, Polaris Dawn will ascend to orbital heights not reached since the Apollo 17 astronauts in 1972 and feature the first attempt at a commercial spacewalk.

“The idea is to develop and test new technology and operations in furtherance of SpaceX’s bold vision to enable humankind to journey among the stars,” Isaacman said during a mission overview briefing on Monday.

But with those feats comes a degree of risk. At their apex, the astronauts will travel through a portion of the hazardous Van Allen radiation belts. And because the Dragon spacecraft that will carry the crew has no airlock, all four astronauts will be exposed to the vacuum of space during the historic spacewalk.

Polaris Dawn is scheduled to launch no earlier than 3:38 a.m. EDT on Monday within a four-hour window from KSC’s Launch Complex 39-A. Earlier this week, the Dragon capsule was transported to the pad, where teams are mating it with a Falcon 9 booster that will make its fourth flight.

Joining Isaacman will be mission pilot Scott “Kidd” Poteet, a longtime friend and coworker of the Shift4 Payments CEO. Poteet served as mission director for Inspiration4, a 2021 orbital mission—also purchased from SpaceX by Isaacman—that featured the first all-civilian crew.

Accompanying them will be the first SpaceX employees to actually fly to space—mission specialists Sarah Gillis and Anna Menon. Gillis, a SpaceX engineer and astronaut trainer, has prepared several NASA crews that have reached the final frontier and was Isaacman’s instructor for Inspiration4. Menon, the company’s lead space operations engineer, will also serve as Polaris Dawn’s medical officer.

This week, crewmembers will conduct a refresher on the mission’s nearly 40 planned experiments, dry dress rehearsal, and launch readiness review. They will spend a maximum of five days orbiting the Earth before splashing down at one of seven locations off the coast of Florida.

Great Heights

Polaris Dawn will waste no time achieving its objectives, beginning with a historic climb on day one.

Hitching a ride on Falcon 9, Dragon will reach space in about 10 minutes and within hours will begin to pass through the inner regions of the Van Allen Belts—a treacherous zone where the risk of damage from radiation is high.

“The Earth’s magnetosphere traps the high energy radiation particles and shields the Earth from the solar storms and the constantly streaming solar wind that can damage technology as well as people living on Earth,” according to NASA. “These trapped particles form two belts of radiation, known as the Van Allen Belts, that surround the Earth like enormous donuts.”

Dragon will ascend to an oval orbit with an apogee of 870 miles, more than three times higher than the International Space Station. It would be the highest orbital altitude reached by humans in half a century.

“Generally speaking, vehicles don’t like radiation, so that’s why we’re going to stay there for the shortest amount of time that’s necessary to gather the data we want,” said Isaacman.

In that time, however, the crew will perform plenty of experiments, leveraging the unique high-radiation environment to potentially learn from it. The Polaris program and SpaceX have partnered with more than 30 institutions around the world to perform the research, which will focus largely on human health.

“We are born into 1G,” said Menon. “When you go into 0G, whether it’s for five days or a nine-month trip to Mars, things change. You have bone density loss, you have vision changes, you have severe motion sickness, and we don’t have answers for all of that.”

To search for them, the astronauts will don special contact lenses that measure the pressure inside of their eyes and will test ways to reduce the disorientation experienced when returning to Earth, for example.

Research will continue throughout the mission. On the fourth day, the crew will test out a specially designed communication system in Dragon’s trunk, which will use laser beams to communicate with SpaceX Starlink satellites as they zip through space. According to Gillis, the demonstration will be livestreamed and worth tuning into, though she did not get into specifics.

Polaris Dawn is also a charitable endeavor, aiming to raise money for St. Jude Children’s Research Hospital. Menon, for example, will debut a children’s book she wrote, the proceeds for which will go to cancer research, during day two of the flight. The SpaceX engineer said the company has installed Starlink terminals at hospitals nationwide to support remote medicine capabilities.

And in a fundraising partnership with Doritos, Polaris Dawn’s cargo will include a container of chips. According to its website, the initiative has raised $500,000. But there won’t be any sticky fingers—the classic Doritos “dust” has been replaced by a special oil-based coating designed to retain flavor.

Isaacman on Monday said Polaris Dawn has already raised “millions” for St. Jude and that he plans to continue the partnership for the Polaris II and Polaris III missions. Inspiration4 raised more than a quarter of a billion for the charity.

Suit Up

Reaching the Van Allen Belts would be a huge feat. But that’s arguably the second-most important—and risky—mission objective.

On the third day of the flight, two of the astronauts will don specially designed SpaceX extravehicular activity (EVA) spacesuits and exit Dragon. They will remain attached to the spacecraft—at one point by just their feet—using mobility aids to maneuver around. The vehicle will be oriented to shield the crew from direct sunlight.

The entire process, from venting to repressurization, will take about two hours and will be livestreamed. Each astronaut will spend 15 to 20 minutes outside the capsule.

“It will look like we’re doing a little bit of a dance,” said Isaacman, “…[but] we’re going through a test matrix on the suit. And the idea is to learn as much as we possibly can about this suit and get it back to the engineers to inform future suit design evolutions.”

But there’s a catch: Dragon does not have an airlock, which means all four crewmembers will be exposed to the vacuum of space.

To remedy this, they will perform a process known as “pre-breathing” beginning just one hour after reaching orbit. The procedure will acclimate the astronauts to a low-pressure environment by gradually reducing the pressure inside the capsule. According to Menon, the idea is to “slowly pull nitrogen out of our body and reduce our risk of decompression sickness.”

On the day of the spacewalk, their spacesuits will be pressurized with 100 percent oxygen for a final pre-breathe. The entire process will take about 45 hours.

Per Isaacman, the spacewalk portion of Polaris Dawn took up the bulk of mission planning, in part due to the development of SpaceX’s EVA suits.

The suits are an evolution of the company’s current apparel, which is designed to be worn only inside Dragon. The upgraded digs feature added mobility and materials pulled from Falcon 9’s trunk and interstage. A 3D-printed helmet includes a heads-up display, which shows spacesuit pressure, temperature, and humidity, as well as a clock to track the astronauts’ time in the void. The suit’s temperature can even be controlled using a dial.

“You might think that we would be extremely cold out in the vacuum of space, and actually we’re more concerned about being too warm,” said Menon.

The suits have undergone an “incredibly expensive testing campaign” with the crew, which has spent about 100 hours wearing them. Because the hardware is “constantly evolving,” per Menon, it could not be tested in a pool. Instead, the astronauts used special harnesses to simulate weightlessness and wore heavy down suits—the kind you’d need at the top of Mount Everest—over their EVA suits.

“We’re really trying to create an environment that doesn’t have convection, looking at thermals, looking at what we’ll actually experience in these suits,” said Menon. “We’ve covered everything from lifecycle testing, pressure testing, [micrometeoroid and orbital debris] testing, extreme hot and cold testing, [and] an entire campaign on [electrostatic discharge] and flammability testing.”

That level of rigor extended to the Dragon capsule, which itself required a few key modifications for the mission. SpaceX added a nitrogen repressurization system, for example, and made upgrades to the spacecraft’s environmental sensors and life support system.

“This includes adding a lot more oxygen to the spacecraft so we can feed oxygen to four suits through umbilicals for the full duration of the spacewalk,” said Menon.

Outside Dragon’s hatch, engineers installed what SpaceX calls the Skywalker, a structure that will help the astronauts find their footing in zero gravity. Atop the Skywalker is a new camera that will capture footage of the spacewalk. Handholds and footholds were added to the capsule’s interior.

In addition, all of that hardware has been “baked out” in a thermal vacuum chamber, Menon said, to burn off chemicals that could produce toxic gas when the capsule is vented.

Thousands of Hours

The astronauts have already prepared extensively for the spacewalk. They recently walked through the entire prebreathe process and venting and repressurization sequence, for example, inside the vacuum chamber at Johnson Space Center.

But that was only the tip of the iceberg.

“I can tell you without a doubt this has been some of the most challenging training that I’ve ever experienced, and I could not imagine a more qualified crew than these three individuals,” said Poteet, a retired U.S. Air Force fighter pilot and member of the Thunderbirds.

The astronauts performed zero-gravity flights in the vacuum chamber, trained in a centrifuge to experience g-forces, and spent time in an altitude chamber to get familiar with symptoms of hypoxia—a condition caused by low oxygen levels in the body. The crew also used a pressure chamber to practice many of the experiments they will conduct in space back on Earth. Gillis and Menon underwent medical training at partner hospitals to be qualified to care for the team.

Each crewmember also spent about 2,000 hours in a simulator, poring over spacecraft and system manuals, communication methods, crew resource management, and contingency scenarios.

“To put this into perspective, I flew fighters for 20 years—I accomplished about 1,500 hours in the simulator training for combat,” said Poteet.

Another key component of training was, as Poteet put it, “getting comfortable in uncomfortable scenarios.” Over the past few years, the crew has gone scuba diving and skydiving, flown fighter jets, and even summited Cotopaxi in Ecuador, a nearly 20,000-foot peak.

“When it’s a multiday journey to get to the summit, you’re dehydrated, you’re hungry, you’re grouchy…it sucks,” said Poteet. “And you learn a lot about yourself under this stressful environment, and you learn a lot about each other.”

‘The 737 for Human Spaceflight’

Though it was purchased by an outside stakeholder, Polaris Dawn has some major implications for SpaceX.

For one, it will be the company’s first mission with crew since Falcon 9 was grounded by the FAA in July. The rocket was quickly cleared for a return to action and has since completed several Starlink launches.

But the mission’s success—or lack thereof—could also inform the timeline of SpaceX’s Starship, the largest and most powerful rocket ever built.

Polaris Dawn is the first of three missions purchased by Isaacman. Little is known about the second, Polaris II, which will also use Dragon and Falcon 9. But Polaris III is intended to be the debut human spaceflight mission for Starship, which so far has completed four orbital test flights.

“It could very well be the [Boeing] 737 for human spaceflight someday,” said Isaacman. “But it’ll certainly be the vehicle that will return humans to the moon and then on to Mars and beyond.”

SpaceX CEO Elon Musk has grand ambitions for Starship, such as ferrying humans to Mars in order to create a colony. But they will hinge on the company remaining on schedule—and, hopefully, learning as much as possible about its EVA spacesuits during Polaris Dawn.

Within one week of Dragon’s splashdown, the firm plans to host a Polaris Dawn mission debrief and question-and-answer session on X Spaces.

That’s not the beginning of a bad joke, but rather a description of SpaceX’s newly announced human spaceflight mission, which as soon as this year will send four astronauts to the ends of the Earth for the first time in history.

The company on Monday unveiled Fram2—a mission to explore the planet’s polar regions, over which no spacecraft has ever flown directly. During the three-to-five-day mission, which will launch from Florida atop SpaceX’s Falcon 9 rocket, the crew will enter a 90-degree polar orbit and observe the Arctic and Antarctic wilderness through a cupola fitted to the company’s Dragon capsule.

No crewed spacecraft has ever reached an orbital path higher than 65 degrees, a feat the Soviet Vostok 6 mission, which carried the first woman to space, achieved in 1963. Typically, such orbits are occupied by smaller satellites, while larger spacecraft such as the International Space Station fly closer to the equator.

The expedition, named after the ship Fram used by Norwegian explorers to reach the poles in the late 19th century, will be Dragon’s sixth commercial astronaut mission and third free-flying mission. The spacecraft has flown three private missions to the ISS for customer Axiom Space, completed the Inspiration4 private orbital spaceflight on behalf of billionaire entrepreneur Jared Isaacman, and will launch another mission for Isaacman—Polaris Dawn—as soon as this month.

“Polaris Program, Inspiration4, Axiom, & now Fram2 showcase what commercial missions can achieve thanks to @SpaceX’s reusability and NASA’s vision with the commercial crew program,” Isaacman said in a post on social media platform X, which is owned by SpaceX CEO Elon Musk. “All just small steps towards unlocking the last great frontier.”

Fram2 similarly is backed by a wealthy CEO, entrepreneur and adventurer Chun Wang, who made his fortune from Bitcoin mining. Wang purchased the mission for an undisclosed amount and will serve as commander.

According to his profile on X, Wang is an avid traveler who has visited half of the world’s countries and territories. But he has grander aspirations.

“I’ve read many sci-fi stories about the first human missions to Mars, usually led by NASA or some fictional government,” Wang said in a post on X. “Rarely does anyone dare to imagine such a mission may be carried out privately. But now, I increasingly believe that someday we will reach Mars—and it may be a person, or a company, not a nation, who gets there.”

Accompanying Wang will be commander Jannicke Mikkelsen of Norway, pilot Eric Philips of Australia, and mission specialist Rabea Rogge of Germany, who told the website Everyday Astronaut they befriended the blockchain entrepreneur on a trek to the North Pole. All four crew members will be making their first trip to the final frontier.

Mikkelson is a filmmaker who seeks out remote or hazardous filming locations and served as payload specialist on the 2019 One More Orbit mission—a record-breaking polar circumnavigation flight on the 50th anniversary of Apollo 11.

According to its website, Fram2 will shatter One More Orbit’s high water mark of 46 hours and 40 minutes, achieved in a Qatar Executive Gulfstream G650ER ultra-long-range business jet, by flying from the north to south pole in just 46 minutes.

Philips, a polar adventurer and guide, knows those regions well, having completed several ski expeditions. But viewing them from orbit has never been possible, even for astronauts on the ISS, to whom they appear invisible.

Fram2 will orbit at about 264-280 miles above Earth, allowing the crew to study strange green and purple light emissions known as Strong Thermal Emission Velocity Enhancements (STEVE), atmospheric phenomena that resemble auroras. Researchers have yet to determine what causes the optical abnormalities. The mission will weigh input from space physicists and citizen scientists alike.

“Having spent much of my adult life in the polar regions this is an incredible opportunity to view the Arctic and Antarctica from space, in particular Antarctica which will be fully lit at this time of year,” said Philips.

Rogge similarly has a fascination with extreme environments, having researched ocean robotics in the Arctic in pursuit of ways to improve the technology. She will get the chance to study tools that could prepare humans for future missions to Mars and beyond, “from capturing the first human x-ray images in space to Just-in-Time training tools to the effects of spaceflight on behavioral health,” according to Fram2’s webpage. The crew will also study what happens to the human body after weeks or months in space.

“Wang aims to use the mission to highlight the crew’s explorational spirit, bring a sense of wonder and curiosity to the larger public, and highlight how technology can help push the boundaries of exploration of Earth and through the mission’s research,” SpaceX said in an update on its website.

Since 2020, SpaceX has flown 50 astronauts to low-Earth orbit across 13 human spaceflight missions, more than any private company. These include the three Axiom Space missions, Inspiration4, and eight NASA Commercial Crew rotation missions to the ISS, as well as the Demo-2 test flight.

Competitors Blue Origin and Virgin Galactic, meanwhile, have each completed seven commercial human spaceflights.

All three companies, in addition to NASA contractors such as Boeing and Northrop Grumman, are part of an emerging trend that could soon become the norm. NASA has predicted that when the ISS is retired at the end of the decade, it could become one of many customers enlisting the services of private spaceflight companies, rather than a provider of those services.

That could mean more private astronaut missions financed by millionaire and billionaire backers.

The post SpaceX Unveils Historic Polar Orbit Mission Backed by Crypto Magnate appeared first on FLYING Magazine.

NASA officials on Wednesday held a media briefing, during which stakeholders revealed that confidence in Starliner’s ability to return the astronauts is waning. According to Ken Bowersox, associate administrator of the agency’s Space Operations Mission Directorate, teams are “getting more serious about evaluating our other options.”

The primary alternative, officials said, is to fly SpaceX’s upcoming Crew-9 mission with two astronauts rather than four, leaving room for Wilmore and Williams to hitch a ride when that mission concludes in February. They estimated that NASA will make a decision by mid-August.

“We could take either path,” Bowersox said.

Boeing and SpaceX representatives were not present on the call, the intention of which, NASA said, was to provide the agency’s perspective on the mission.

On its way up to the ISS, Starliner suffered two main issues that are giving crews pause over how to return the astronauts. A set of helium leaks that emerged on the spacecraft have since stabilized, according to NASA. However, the other issue, which involves five faulty reaction control system (RCS) thrusters on Starliner’s expendable service module, is still being evaluated.

Officials on Wednesday said ground testing of an identical thruster at White Sands Test Facility in New Mexico revealed that the problem is linked to a tiny Teflon seal on an oxidizer poppet, which controls the flow of propellant into the thruster. Teams theorize that the extreme heat the thrusters experienced during Starliner’s rendezvous with the ISS caused the Teflon to expand, inhibiting flow and causing them to fire at weaker-than-expected levels.

According to Steve Stich, who manages NASA’s Commercial Crew program, a July 27 Starliner hot fire test showed that the affected thrusters—with the exception of one, which has been deactivated—are now firing as expected. This has led engineers to hypothesize that the teflon seals contracted and are no longer blocking propellant from reaching the thrusters. Now, the task is to understand how and why.

Teams are working to better understand how those seals might behave during Starliner’s return trip, but there is not yet consensus on whether they are good to go. According to Bowersox and Stich, there is internal disagreement about returning the astronauts on Starliner versus Dragon, which was amplified with the discovery of the faulty teflon seal.

“We heard enough voices [on the program control board] that the decision is not clear,” said Bowersox.

The officials explained that Boeing, which on Friday asserted it has high confidence in Starliner, is viewing risk based on previous missions and flight performance, while NASA wants to understand the root cause of the issue before it has confidence in returning with crew. Ultimately, NASA administrator Bill Nelson will have the final say.

“Reasonable people could have different views on which path we should take,” said Bowersox, who acknowledged that the chance of an uncrewed return has risen in recent weeks. “I don’t think anyone has taken a view that you could prove is wrong or right.”

NASA will have until mid-August to decide whether the Dragon contingency plan should be put into action.

The ISS has two docking modules that are occupied by Starliner and SpaceX’s Crew-8 capsule, meaning Starliner would need to autonomously undock before Crew-9 launches on September 24. Crew-8 would then depart the space station with the crew of NASA’s Expedition 71, and the Crew-9 Dragon would take its place, leaving one docking port open for the next SpaceX cargo mission. Wilmore and Williams would stay for the duration of Crew-9, flying home with the two-person Expedition 72 crew in February.

The problem, though, is that Starliner’s flight software is not currently capable of an autonomous undocking despite having achieved the feat during an uncrewed mission in 2022.

For the CFT, the software was configured for a crewed undocking, as per the mission profile. Now, Boeing and NASA must modify the mission data load to reconfigure the system for an uncrewed undocking, which sources say could take up to one month. NASA said the spacecraft has built-in fault tolerance that would prevent it from colliding with the ISS should its thrusters not perform as expected during that maneuver.

The agency said it has been in daily communication with Wilmore and Williams and that the astronauts are prepared for whatever path it ultimately takes. If they stay along with Crew-9, they will assist personnel with scientific research, including spacewalks. Additional materials, such as spacesuits, would be sent up with the Dragon.

“Butch and Suni are ready to support whatever we need to do,” said Dana Weigel, manager of NASA’s ISS program.

Officials insist that despite the internal conflict around Starliner, the vehicle could still be used to return the astronauts in the case of a contingency on the ISS. In those scenarios, Bowersox said, NASA is willing to tolerate a higher level of risk—one that is jeopardizing teams’ ability to complete the CFT as intended.

The worst-case scenario, according to NASA, would be if the helium leak and thruster issues converge during Starliner’s deorbit burn, the maneuver that will place it back in Earth’s atmosphere. An unlikely combination of technical failures could impact the ability of the RCS thrusters to maintain the capsule’s orbital trajectory, though agency research predicts that it could complete the maneuver even with multiple failures.

The mission, dubbed Crew-8, lifted off  from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 10:53 p.m. EST, marking NASA’s eighth commercial ISS crew rotation.

The launch had initially been planned for Friday but was delayed twice due to high winds along the spacecraft’s ascent path.

“On this eighth crew rotation mission, we are once again showing the strength of our commercial partnerships and American ingenuity that will propel us further in the cosmos,” NASA Administrator Bill Nelson said Monday. “Aboard the station, the crew will conduct more than 200 science experiments and technology demonstrations to help fuel this new era of space exploration and benefit humanity here on Earth,” 

The crew is scheduled to arrive at ISS on Tuesday around 3 a.m. EST, when the spacecraft will autonomously dock with the forward port of the space station’s Harmony module.

Later this year, Space Force Colonel Nick Hague will pilot a NASA mission to the International Space Station (ISS) on NASA’s SpaceX Crew-9 mission aboard the Dragon spacecraft, the service announced. The mission will be the ninth rotation admission at the space station under NASA’s commercial crew program.

“The core of our mission on the space station is to perform science experiments and collect data,” Hague said. “The [ISS] provides a unique platform in microgravity, which allows researchers from around the world to explore and discover processes that could have significant impact on the behavior of our bodies and the environment around us, both on Earth and off planet.”

The launch, scheduled for no earlier than August, is a history-making first for a Space Force Guardian but marks Hague’s second mission to ISS. In March 2019, Hague, who was then in the Air Force, began a 203-day mission at the space outpost, where he spent nearly 20 hours conducting spacewalks.

Joining Hague on the Crew-9 mission will be Commander Zena Cardman, Mission Specialist Stephanie Wilson, and Roscosmos cosmonaut Mission Specialist Aleksandr Gorbunov. Once the crew arrives at the station, Hague will transition to a flight engineer role. The Crew-9 mission will then conduct a handover with NASA’s SpaceX Crew-8 mission, which is set to launch to the ISS no earlier than February 22.

“Being a part of this mission is a unique honor, but it’s truly a collective effort,” Hague said. “Guardians worldwide ensure safe and secure operations of critical systems for launch and on station. From GPS satellites that underpin our station navigation systems, to space domain awareness sites around the globe that help NASA prevent orbital debris from colliding with the space station, to the launch range that my crew will use when we lift off, Guardians provide critical support without which our NASA human spaceflight program wouldn’t be possible.”
