Live coverage: SpaceX Falcon Heavy launches NASA’s Psyche on mission to a metal asteroid

Watch a replay of the launch and landing of SpaceX’s Falcon 9 rocket on Jan. 7 at Cape Canaveral.

The program manager in charge of Boeing’s Starliner crew capsule program said Friday that additional checks would have uncovered problems with the spaceship’s software that plagued the craft’s first unpiloted orbital test flight in December, but he pushed back against suggestions that Boeing engineers took shortcuts during ground testing.

Investigators believe a leak of propellant inside the Crew Dragon spacecraft’s propulsion system led to the capsule’s explosion April 20 during a ground test at Cape Canaveral, and a senior SpaceX official said Monday that delays are making it “increasingly difficult” to fly astronauts on the commercial spaceship before the end of the year.
