Watch a replay of the Falcon 9 rocket’s liftoff from Cape Canaveral Air Force Station as seen from the Kennedy Space Center press site roughly 4 miles away.

United Launch Alliance teams ran through an 11-hour countdown Friday at Cape Canaveral to rehearse procedures before the first flight of a modified Atlas 5 rocket with Boeing’s Starliner crew capsule Dec. 20.

SpaceX launched the next group of satellites for the company’s Starlink broadband network Wednesday at 9:25 p.m. EDT (0125 GMT Thursday) from pad 40 at Cape Canaveral Air Force Station. The satellites rode into orbit on a Falcon 9 rocket with a first stage flown on four previous missions, and the booster made a successful fifth landing on a SpaceX drone ship in the Atlantic Ocean.
