The Starliner capsule was supposed to make its debut this month, after a series of postponements. But the first test flight is now off until August. And the second test flight, with astronauts, won’t occur until late in the year.
NASA announced the revised lineup Wednesday. At the same time, officials said the first Starliner crew will remain at the International Space Station longer than the few weeks originally anticipated. The mission length will be decided later.
SpaceX, NASA’s other commercial crew provider, successfully flew its new Dragon capsule without a crew to the International Space Station last month. The first flight with astronauts could be as early as this summer, but the schedule is under review.
