Two NASA astronauts stranded in area since early June lastly have their flight dwelling booked: they may return to Earth on SpaceX’s Dragon capsule in February.
The choice represents a vote of confidence in Elon Musk’s SpaceX, which not solely received the race to ferry astronauts with a yearslong lead however is now being trusted to complete a job that Boeing began. The 2 spacefarers, Butch Wilmore and Suni Williams, launched on June 5 on a mission that was by no means assured to be an uneventful flight; they have been the primary passengers to ever fly onboard the Starliner car, constructed by veteran contractor Boeing. Now their mission might be extra difficult than initially deliberate—and months longer than anybody anticipated.
“Spaceflight is risky, even at its safest and even at its most routine,” mentioned NASA administrator Invoice Nelson throughout a information convention that the company held on Saturday. “A test flight, by nature, is neither safe nor routine.”

Wilmore and Williams additionally confronted a number of delays forward of their launch earlier this yr. Once they lastly did blast off, they reached the Worldwide Area Station (ISS) safely. However the flight included a number of small anomalies, notably helium leaks and thruster failures within the car’s propulsion system. Because the two arrived in orbit, NASA and Boeing have been intensively troubleshooting their car, a capsule nicknamed Calypso.

However NASA stays unhappy that engineers notably perceive the thruster scenario effectively sufficient to entrust the company’s astronauts to the car. Each NASA group that officers mentioned had been polled about Starliner’s return—representing a couple of dozen workplaces in all—opted for an uncrewed flight, mentioned Ken Bowersox, affiliate administrator for area operations at NASA, through the press convention. “There was just too much uncertainty in the prediction of the thrusters,” added Steve Stich, program supervisor of NASA’s Industrial Crew Program.
For NASA, the choice represents a setback to its plans for having two dependable crew autos that may routinely carry astronauts into area. However regardless of the awkward optics of the brand new association, altering the return experience for Wilmore and Williams beats the choice, says Wendy Whitman Cobb, a political scientist on the Faculty of Superior Air and Area Research.
“The hit would have been worse if they had made a decision that put astronauts’ lives in danger,” Whitman Cobb says. “I think this is probably the least risky option for NASA at this point.”
The shake-up in plans shows NASA’s excessive stage of confidence within the SpaceX Dragon car. Along with counting on Musk’s firm for entry to the ISS, NASA has entrusted SpaceX not solely with launching a host of high-profile science missions but in addition with touchdown astronauts on the lunar floor—and even with constructing the car that may ultimately destroy the area station in orbit.
For Boeing, NASA’s resolution is probably going a painful one, each by way of the corporate’s repute and its stability sheet. “I’m sure this is a big blow to them,” Whitman Cobb says. “Their financial statements have already shown that they have taken a pretty substantial monetary hit; this is going to be another one.”
On the press convention, nonetheless, Nelson and different NASA officers emphasised that the company and Boeing are each nonetheless dedicated to creating Starliner a daily working customer to the area station. All alongside, NASA has highlighted the significance of getting two U.S.-built autos which might be able to reaching the orbiting laboratory simply in case a problem with one spaceship leaves it briefly grounded. When requested how assured he was that Starliner would fly a crew once more, Nelson mentioned, “100 percent.”
No Boeing representatives attended NASA’s information convention on Saturday, however the firm issued an announcement that learn, “We continue to focus, first and foremost, on the safety of the crew and spacecraft. We are executing the mission as determined by NASA, and we are preparing the spacecraft for a safe and successful uncrewed return.”
NASA is accustomed to weighing the lives of its astronauts in its decision-making, and officers usually speak concerning the methods the disasters of the Challenger area shuttle in 1986 and the Columbia shuttle in 2003 have formed the company’s “safety culture.” On the information convention on Saturday, Nelson referenced the misplaced shuttle crews and the way in which these incidents have modified NASA’s tradition. However each shuttles have been operated totally by the company, and a few specialists have lengthy questioned whether or not the daybreak of business missions would muddy the waters when it got here to security requirements in area.
The Path to Earth
As issues stand now, Starliner will fly dwelling empty within the coming weeks whereas Wilmore and Williams stay in orbit for one more six months—a dramatic change of their work schedule. The duo will put together the Boeing car for departure after which bid farewell to it in early September. The empty capsule will sail by means of Earth’s ambiance for a deliberate landing within the New Mexico desert. (Crew-8, the Dragon car that’s at present docked to the area station, might be briefly reconfigured to carry six folks simply in case an emergency requires astronauts to evacuate, NASA officers mentioned.)
Then, a couple of month from now, SpaceX will launch its deliberate Crew-9 mission, which can carry solely two of the 4 crew members who have been beforehand assigned: NASA astronauts Zena Cardman, Nick Hague, and Stephanie Wilson and Russian cosmonaut Aleksandr Gorbunov. NASA has not but decided who will stay on the flight, in response to Norman Knight, director of flight operations.
Wilmore, Williams and their two new companions will stay in orbit for the standard six-month stint and can conduct varied science experiments earlier than they head for Earth in early 2025. (NASA has additionally confirmed that Wilmore and Williams have been skilled to carry out area walks throughout an prolonged keep.)
A Decade of Bumps
The empty Starliner return represents one other problem for Boeing in a decade-long sequence of them. In 2014 NASA chosen each Boeing and SpaceX to develop autos that will be able to ferrying astronauts to and from the ISS. The company had retired its fleet of shuttles in 2011, only a decade into the station’s steady occupation, and it discovered itself within the uncomfortable place of counting on Russia for transportation to and from the ISS.
The contracts with these personal operators have been meant to see astronauts launching by 2017—a time line neither firm was in a position to meet. SpaceX constructed on its earlier success in utilizing Dragon capsules to run resupply missions to the orbital outpost, and it efficiently and easily carried out a crewed check mission in 2020. Since then SpaceX has accomplished seven normal crew missions for NASA. Its eighth such mission is in orbit now and can return subsequent month.
Boeing, in the meantime, was ranging from scratch in constructing its Starliner car, an endeavor that has taken a rocky street within the intervening decade. The corporate was lastly able to launch its uncrewed check flight in December 2019. However the spacecraft—the identical capsule now in orbit—burned an excessive amount of gas within the minutes after launch, leaving it unable to succeed in the ISS.
After the incident, Starliner spent two and a half years grounded (partially due to a dozen defective valves) earlier than it executed a profitable uncrewed check flight in Might 2022. However that mission wasn’t flawless both: thruster points marred the experience to the area station. Final summer time Boeing misplaced one other yr due to a mixture of parachute points and the discovery {that a} extremely flammable sort of tape had been used all through the capsule.
In early Might Starliner headed to the launchpad to execute its very important crewed flight check—the ultimate milestone standing between Boeing and common journeys to the ISS. However the mission group scrubbed the launch due to valve issues, which necessitated a monthlong pause earlier than the subsequent try. That subsequent attempt was then referred to as off lower than 4 minutes earlier than flight due to a helium leak within the propulsion system.
So it was the second time in lower than per week when Wilmore and Williams climbed onboard Starliner, greater than 100 ft above the launchpad, on June 5. The astronauts anticipated a mere weeklong jaunt to the area station—the third profession go to for every. In the course of the journey, nonetheless, the propulsion system sprang two extra helium leaks, 5 of the car’s thrusters failed, and the capsule’s cooling system guzzled an excessive amount of water.
Not one of the points was notably regarding by itself, however the mixture made a giant impression. Inside only a few days of Wilmore and Williams’ arrival in orbit, NASA started delaying their return flight. By mid-June, company personnel mentioned preserving the 2 in orbit whereas engineers gathered as a lot knowledge as doable on components of the car that may fritter away throughout reentry—not out of any concern for the car’s security however merely to raised perceive future missions.
Returning to Flight
Nonetheless to be decided is Starliner’s path again to creating flights. Although Boeing representatives weren’t included in Saturday’s press convention, Nelson mentioned that, earlier within the day, he had spoken with Boeing CEO Kelly Ortberg, who took workplace simply greater than two weeks in the past. “He expressed to me an intention that they will continue to work the problems once Starliner is back safely,” Nelson mentioned.
Questions stay, nonetheless. NASA officers declined to specify whether or not they can be keen to certify Starliner for normal crewed missions now that it received’t be used to carry Wilmore and Williams dwelling or whether or not they would think about assigning a full four-astronaut contingent to the subsequent crewed flight. It’s additionally not clear what NASA’s worldwide companions on the area station, notably Russia, might want to see earlier than trusting their very own astronauts to a brand new car.
All these concerns will develop into clearer in a couple of weeks, when Starliner is again on Earth and within the fingers of NASA and when Boeing engineers consider the trail ahead. Whitman Cobb says the important thing think about Starliner’s future might be whether or not both group requires adjustments be made to the car. “Any time you have to go in and change something on the capsule, on the system,” she says, “that’s probably going to take a lot longer.”
