The seemingly star-cross Boeing Starliner — within minutes of its long-delayed blastoff on the spacecraft’s first piloted test flight — was grounded again Saturday when one of three redundant computers managing the countdown from the base of the launch pad ran into a problem, triggering a last-minute scrub.
An Atlas 5 rocket carrying astronauts for the first time was fueled for blastoff Monday night to boost Boeing’s long-delayed Starliner crew ferry ship into orbit for its first piloted test flight. But trouble with a valve in the rocket’s upper stage forced mission managers to order a scrub just two hours before takeoff.
Years behind schedule and more than a billion dollars over budget, Boeing’s Starliner capsule is finally poised for its first piloted launch Monday, a critical test flight carrying two veteran astronauts to the International Space Station and in so doing, demonstrate an alternative to SpaceX’s already operational Crew Dragon.
