Boeing’s first astronaut mission ended Friday night time with an empty capsule touchdown and two take a look at pilots nonetheless in house, left behind till subsequent yr as a result of NASA judged their return too dangerous.
Six hours after departing the Worldwide Area Station, Starliner parachuted into New Mexico’s White Sands Missile Vary, descending on autopilot by means of the desert darkness.
It was an uneventful near a drama that started with the June launch of Boeing’s long-delayed crew debut and shortly escalated right into a dragged-out cliffhanger of a mission suffering from thruster failures and helium leaks. For months, Butch Wilmore and Suni Williams’ return was in query as engineers struggled to know the capsule’s issues.
Boeing insisted after intensive testing that Starliner was protected to carry the 2 house, however NASA disagreed and booked a flight with SpaceX as an alternative. Their SpaceX journey gained’t launch till the top of this month, which implies they’ll be up there till February — greater than eight months after blasting off on what ought to have been a fast journey.
Wilmore and Williams ought to have flown Starliner again to Earth by mid-June, per week after launching in it. However their journey to the house station was marred by the cascade of thruster bother and helium loss, and NASA finally determined it was too dangerous to return them on Starliner.
So with contemporary software program updates, the totally automated capsule left with their empty seats and blue spacesuits together with some outdated station tools.
“She’s on her manner house,” Williams radioed because the white and blue-trimmed capsule undocked from the house station 260 miles (420 kilometers) over China and disappeared into the black void.
Williams stayed up late to see how every little thing turned out. “An excellent touchdown, fairly superior,” mentioned Boeing’s Mission Management.
Cameras on the house station and a pair of NASA planes caught the capsule as a white streak coming in for the landing, which drew cheer.
There have been some snags throughout reentry, together with extra thruster points, however Starliner made a “bull’s-eye touchdown,” mentioned NASA’s business crew program supervisor Steve Stich.

Even with the protected return, “I feel we made the precise determination to not have Butch and Suni on board,” Stich mentioned at a information convention early Saturday. “All of us really feel completely happy in regards to the profitable touchdown. However then there’s a chunk of us, all of us, that we want it could have been the best way we had deliberate it.”
Boeing didn’t take part within the Houston information briefing. However two of the corporate’s prime house and protection officers, Ted Colbert and Kay Sears, informed staff in a word that they backed NASA’s ruling.
“Whereas this may occasionally not have been how we initially envisioned the take a look at flight concluding, we help NASA’s determination for Starliner and are pleased with how our staff and spacecraft carried out,” the executives wrote.
Starliner’s crew demo capped a journey stuffed with delays and setbacks. After the house shuttles retired greater than a decade in the past, NASA employed Boeing and SpaceX for orbital taxi service. Boeing bumped into so many issues on its first take a look at flight with nobody aboard in 2019 that it needed to repeat it. The 2022 do-over uncovered much more flaws and the restore invoice topped $1 billion.
SpaceX’s crew ferry flight later this month can be its tenth for NASA since 2020. The Dragon capsule will launch on the half-year expedition with solely two astronauts since two seats are reserved for Wilmore and Williams for the return leg.
As veteran astronauts and retired Navy captains, Wilmore and Williams anticipated hurdles on the take a look at flight. They’ve stored busy in house, serving to with repairs and experiments. The 2 at the moment are full-time station crew members together with the seven others on board.
Even earlier than the pair launched on June 5 from Cape Canaveral, Florida, Starliner’s propulsion system was leaking helium. The leak was small and considered remoted, however 4 extra cropped up after liftoff. Then 5 thrusters failed. Though 4 of the thrusters had been recovered, it gave NASA pause as as to if extra malfunctions would possibly hamper the capsule’s descent from orbit.
Boeing carried out quite a few thruster assessments in house and on the bottom over the summer time, and was satisfied its spacecraft might safely carry the astronauts again. However NASA couldn’t get snug with the thruster state of affairs and went with SpaceX.
Flight controllers carried out extra take a look at firings of the capsule’s thrusters following undocking; one didn’t ignite. Engineers suspect the extra the thrusters are fired, the warmer they turn into, inflicting protecting seals to swell and impede the stream of propellant. They gained’t have the ability to study any of the elements; the part holding the thrusters was ditched simply earlier than reentry.
Starliner can be transported in a pair weeks again to NASA’s Kennedy Area Heart, the place the analyses will unfold.
NASA officers pressured that the house company stays dedicated to having two competing U.S. corporations transporting astronauts. The purpose is for SpaceX and Boeing to take turns launching crews — one a yr per firm — till the house station is deserted in 2030 proper earlier than its fiery reentry. That doesn’t give Boeing a lot time to catch up, however the firm intends to push ahead with Starliner, in keeping with NASA.
Stich mentioned post-landing it’s too early to know when the subsequent Starliner flight with astronauts would possibly happen.
“It would take some time to find out the trail ahead,” he mentioned.
