Starliner’s lengthy area odyssey is over.
The Boeing capsule, named Calypso, returned to Earth early this morning (Sept. 7), touching down within the New Mexico desert at 12:01 a.m. EDT (0401 GMT; 11:01 p.m. native time on Sept. 6).
“Nice touchdown of Calyspo!” NASA astronaut Suni Williams stated on the company’s webcast. “I do not suppose that would have gone higher.”
The touchdown was long-delayed, coming greater than three months into an orbital mission initially anticipated to final about 10 days. And, whereas Starliner launched with two NASA astronauts aboard — Williams and Butch Wilmore — no person rode it house.
It wasn’t supposed to finish like this.

A vital take a look at flight
The roots of the just-completed mission, often known as Crew Flight Take a look at (CFT), return a decade. In 2014, NASA gave SpaceX and Boeing multibillion-dollar contracts to complete work on their astronaut taxis — capsules often known as Crew Dragon and Starliner, respectively.
The company wished one or each of these autos to begin flying astronauts to and from the Worldwide Area Station (ISS) by 2017, reestablishing a homegrown orbital human spaceflight functionality — one thing the U.S. had lacked because the retirement of the area shuttle in 2011.

Neither capsule hit that bold goal. SpaceX’s first astronaut mission, a take a look at flight to the ISS known as Demo-2, lifted off in Might 2020. Starliner’s crewed debut was CFT, which launched atop a United Launch Alliance Atlas V rocket on June 5, sending Williams and Wilmore to the orbiting lab for a deliberate eight-day keep.
CFT had been slated to fly final yr, but it surely was delayed to take care of parachute points and to take away massive quantities of insulating tape from the capsule’s wiring system. (Analsyes decided that the tape was flammable and thus posed a security threat.)
The mission encountered points extra lately as properly. A deliberate Might 25 launch try was scrubbed, for instance, after group members observed a small helium leak in Starliner’s service module. Extra helium leaks popped up after launch, as Starliner chased the ISS down in orbit. And, extra concerningly, the capsule skilled propulsion issues: 5 of its 28 response management system (RCS) thrusters conked out not lengthy after liftoff.
The thruster issues scuttled Starliner’s first ISS docking try on June 6. The capsule succeeded on its second strive that day, and group members finally introduced 4 of the 5 defective thrusters again on-line. However the problem loomed massive over the remainder of the mission.
A troublesome choice
NASA prolonged CFT’s orbital keep repeatedly, giving mission group members extra time to investigate and troubleshoot the thruster issues. Such work included modeling research and testing each in area (with Starliner) and on the bottom (with a Starliner RCS thruster at NASA’s White Sands Take a look at Facility in New Mexico).
Finally, NASA concluded that bringing Williams and Wilmore house on Starliner posed an unacceptable security threat.
“The choice to maintain Butch and Suni aboard the Worldwide Area Station and convey Boeing’s Starliner house uncrewed is the results of our dedication to security: our core worth and our North Star,” NASA Administrator Invoice Nelson stated in a press release on Aug. 24, the day the company introduced the information.

Williams and Wilmore will keep aboard the ISS till February, after they’ll hitch a experience house on a SpaceX Crew Dragon — the one flying the corporate’s Crew-9 mission, which is ready to elevate off later this month. To make room for them, Crew-9 will elevate off with two astronauts as a substitute of the same old 4.
Starliner, in the meantime, was packed up for an uncrewed return to Earth. Among the many gear that it carried house had been the “Boeing Blue” spacesuits that Williams and Wilmore wore aboard the capsule. The astronauts haven’t any want for them now.
“The fits should not appropriate,” Steve Stich, supervisor of NASA’s Industrial Crew Program, stated throughout a press convention on Wednesday (Sept. 4). “So the Starliner fits wouldn’t work in Dragon, and vice versa.”
Starliner undocked from the ISS on Friday (Sept. 6) at 6:04 p.m. EDT (2204 GMT) as deliberate. It carried out a sequence of burns to set itself up for the uncrewed touchdown, which occurred underneath parachutes in New Mexico’s White Sands Area Harbor simply after midnight in the present day.
It was the third landing total for Starliner. The capsule additionally flew two uncrewed take a look at flights to the ISS, one in December 2019 and one in Might 2022. Starliner failed to fulfill up with the orbiting lab on the primary flight after struggling a number of glitches. The second uncrewed mission was a hit, although Starliner skilled some thruster points on that flight as properly. (These had been a unique set, related not with the RCS however with Starliner’s orbital maneuvering and management system.)
A cloudy future
Boeing and NASA had hoped that CFT would pave the best way for Starliner’s certification, permitting the capsule to start flying six-month-long astronaut missions to the ISS.
The primary such operational flight, Starliner-1, had been focused for February 2025. That launch has already been pushed again, nonetheless, to August 2025 on the earliest. And it is unclear for the time being if Starliner can be licensed by then — or what further checks, if any, NASA would require earlier than certification can happen.
“I believe what we have to do now’s actually lay out the general plan, which we’ve not had time to do,” Stich stated within the Sept. 4 press convention.
“We have not, as a result of the groups have been so targeted on this flight, laying out that total search technique, the general quantity of labor we have got to go do,” he added. “After which once we do this, we’ll have a greater understanding of, When can we certify the automobile, and when can we resume flights?”
Crew Dragon, in the meantime, was licensed shortly after Demo-2’s profitable conclusion in 2020. The SpaceX automobile is now gearing up for its ninth operational astronaut flight to the ISS for NASA. (That will be Crew-9, because the title suggests.)
SpaceX has additionally flown a handful of personal crewed missions to the station, in addition to the Inspiration4 astronaut flight to Earth orbit, which didn’t meet up with the orbiting lab. And it is getting ready to launch Polaris Daybreak, one other free-flying business astronaut mission, which goals to conduct the first-ever personal spacewalk.
