Live coverage: Falcon 9 launches with Thai satellite and first stage lands at sea

SpaceX test-fired the Falcon 9 rocket early Saturday ahead of launch with the next four astronauts heading to the International Space Station. The static fire test before sunrise Saturday in Florida was a major step toward liftoff Thursday.

A SpaceX Falcon 9 rocket darted into a partly cloudy sky over Florida’s Space Coast with a roar Thursday afternoon, carrying the Japanese-built Es’hail 2 communications satellite into space to beam commercial video and data services across the Middle East and expand connectivity for Qatar’s military.

A major test of the system that would shoot SpaceX astronaut crews away from a failing rocket is scheduled for no earlier than May 5 from a specially-built mount at Cape Canaveral’s Complex 40 launch pad, NASA announced Tuesday.
