A second uncrewed test flight of Boeing’s CST-100 Starliner commercial crew spacecraft is now scheduled for no earlier than the end of March, 15 months after its first, flawed mission.
Chris Ferguson, the former NASA astronaut who was to command the first crewed flight of Boeing’s CST-100 Starliner commercial crew vehicle, has withdrawn from the mission for personal reasons, the company announced Oct. 7.
A NASA safety panel said that while Boeing was making good progress on implementing changes to its CST-100 Starliner commercial crew vehicle, it had doubts that work could be done in time to allow another test flight this year.
NASA and Boeing announced an updated schedule of test flights of the company’s CST-100 Starliner commercial crew vehicle that would allow it to begin operational missions to the International Space Station at the end of 2021.
A NASA astronaut dropped from a mission to the International Space Station more than two years ago will get a second opportunity as part of a Boeing commercial crew mission.
Members of a NASA safety panel expressed continued concern about quality issues with Boeing’s commercial crew spacecraft while cautiously supporting SpaceX’s plans to fly reused spacecraft on future crewed missions.
NASA announced July 7 that it has completed two major reviews that stemmed from Boeing’s flawed commercial crew test flight last December as the agency and company prepare for a second test flight later this year.
A NASA safety panel believes the agency’s plan to launch a SpaceX commercial crew test flight in late May is feasible, although some issues still need to be resolved before the launch.
Boeing announced April 6 that it has decided to fly a second uncrewed test flight of its CST-100 Starliner commercial crew vehicle later this year to confirm it has corrected problems encountered in a test flight last December.
NASA has completed the crew for the first operational SpaceX commercial crew mission to the International Space Station, one that will not include any Russian cosmonauts after Roscosmos officials said they would not fly on what they consider an unproven vehicle.
Although an independent review team has wrapped up its investigation into issues with last December’s uncrewed test flight of Boeing’s CST-100 Starliner, NASA says it will be some time before it decides if a second uncrewed test flight is needed.
As the independent review of last December’s test flight of Boeing’s CST-100 Starliner commercial crew vehicle nears completion, the company said it will perform more rigorous testing to catch errors that slipped through on that flight.
Boeing will reverify all the software on its CST-100 Starliner commercial crew spacecraft after an ongoing investigation found “numerous” problems in the original development process that allowed at least two major problems to escape detection.
A NASA safety panel is recommending a review of Boeing’s software verification processes after revealing there was a second software problem during a CST-100 Starliner test flight that could have led to a “catastrophic” failure.
