The US space agency ended months of speculation about the next flight of Boeing’s Starliner spacecraft, confirming that the vehicle will carry only cargo to the International Space Station. Now the plan is to fly Starliner-1 carrying cargo and then up to three additional missions before the space station is retired. SpaceX, with its Crew Dragon vehicle, flew a successful crew test flight in mid-2020 and its first operational mission before the end of that year. Orbital Flight Test 3? During its approach to the space station, the Starliner spacecraft once again experienced serious thruster issues.
