Boeing’s Starliner astronaut taxi may not get off the ground this year after all.

Boeing and NASA had originally aimed to launch Starliner’s Orbital Test Flight 2 (OFT-2), a crucial uncrewed trial mission to the International Space Station (ISS), from Florida’s Cape Canaveral Space Force Station on July 30. But preflight checks revealed 13 stuck valves in Starliner’s service module, nixing that liftoff plan.

Engineers are still troubleshooting the Starliner valve problem. That fact, combined with a busy launch schedule over the coming weeks and months, could well push OFT-2 into 2022, NASA officials said.

“I think right now, the timeline and the manifest through the end of the year is pretty tight,” Kathy Lueders, head of NASA’s Human Exploration and Operations Mission Directorate (HEOMD), said during a call with reporters on Tuesday (Sept. 21). “So, my gut is it would be probably more likely to be next year. But we’re still working through that timeline.”

Boeing and NASA teams are currently evaluating whether to put a different service module on Starliner for the OFT-2 mission or to proceed with trying to fix the current one, she added. A decision on that could come in the next few weeks.

Boeing has been developing Starliner with the help of funding from NASA’s Commercial Crew Program, which selected the aerospace giant and SpaceX to fly agency astronauts to and from the orbiting lab. SpaceX has already launched two operational crewed missions to the ISS with its Crew Dragon capsule and is gearing up to launch another one next month. But Starliner still needs to ace an uncrewed trip to the station before it can carry astronauts.

As its name suggests, OFT-2 will be the Boeing capsule’s second try at this important test mission. During its first attempt, in December 2019, Starliner suffered several serious software glitches, got stranded in an orbit too low for an ISS meetup and landed back on Earth after orbiting solo for two days.
