Watch the Falcon 9 launch from pad 39A

In parallel with an on-going failure investigation, SpaceX is readying downstream Crew Dragon spacecraft for flight in hopes that corrective actions can be implemented in time to launch two astronauts to the International Space Station before the end of the year, a senior NASA manager said Tuesday.

A powerful commercial communications satellite driven by plasma thrusters rode a reused SpaceX Falcon 9 rocket booster away from Cape Canaveral early Monday, climbing into orbit to connect companies, homes, airplanes and ships across much of the Eastern Hemisphere.

The launch will be preceded by a company talk from Elon Musk, discussing SpaceX’s plans for developing the rocket for Mars exploration. Launch teams are targeting a liftoff from Pad A at Starbase, Texas, on Tuesday, May 27, at 6:30 p.m. CDT (7:30 p.m. EDT, 2330 UTC).
