Boeing’s Starliner spacecraft landed uncrewed in a New Mexico desert late on Friday, capping a three-month test mission hobbled by technical issues that forced the astronauts it had flown to the International Space Station to remain there until next year.
NASA astronauts Butch Wilmore and Suni Williams, who became the first crew to fly Starliner in June, remained on the ISS as Starliner autonomously undocked at 6:04 p.m. ET (2204 GMT) on Friday, beginning a six-hour trek to Earth using maneuvering thrusters that NASA last month deemed too risky for a crew.
The ISS, a football field-sized science lab some 250 miles (402 km) in space, has seven other astronauts on board who arrived at different times on other spacecraft, including a Russian Soyuz capsule. Wilmore and Williams are expected to continue doing science experiments with their crewmates.
Five of Starliner’s 28 maneuvering thrusters failed with Wilmore and Williams on board during their approach to the ISS in June, while the same propulsion system sprang several leaks of helium, which is used to pressurize the thrusters.
Despite successfully docking on June 6, the failures set off a monthslong investigation by Boeing – with some help from NASA – that has cost the company $125 million, bringing total cost overruns on the Starliner program just above $1.6 billion since 2016, according to a Reuters analysis of securities filings.
Boeing’s Starliner woes have persisted since the spacecraft failed a 2019 test trip to the ISS without a crew. Starliner did a re-do mission in 2022 and largely succeeded, though some of its thrusters malfunctioned.
The aerospace giant’s Starliner woes represent the latest struggle that call into question Boeing’s future in space, a domain it had dominated for decades until Elon Musk’s SpaceX began offering cheaper launches for satellites and astronauts and reshaped the way NASA works with private cFompanies.
