Q&A with Elon Musk, founder and CEO of SpaceX (members only)

The Starlink 10-27 mission was the 280th orbital launch for SpaceX from Cape Canaveral Space Force Station. The Falcon 9 rocket lifted off from Space Launch Complex 40 at 6:53 a.m. EDT (1053 UTC).

For the second day running, computers automatically aborted a Falcon 9 launch countdown Monday at NASA’s Kennedy Space Center in Florida in the final seconds before liftoff with the Intelsat 35e communications satellite.

SpaceX’s Falcon 9 rocket took off from Cape Canaveral on Tuesday, powering a commercial Dragon cargo ship into orbit while trying a dicey descent maneuver to return to landing on a ship in the Atlantic Ocean. SpaceX says the booster touched down hard and tipped over after landing.
