Watch the Falcon 9 launch from pad 39A

Russian cosmonaut Anatoly Ivanishin, Japanese flight engineer Takuya Onishi and NASA astronaut Kate Rubins departed the International Space Station on Saturday and headed for a homecoming in Kazakhstan to wrap up a 115-day expedition in orbit. Undocking occurred at 8:35 p.m. EDT Saturday (0035 GMT Sunday), with an on-target landing more than three hours later at 11:58 p.m. EDT (0358 GMT).

SpaceX founder and CEO Elon Musk briefed reporters on the status of the Falcon Heavy test flight, and several of the company’s other projects, shortly after the huge rocket lifted off from NASA’s Kennedy Space Center in Florida.

The launch will be the first human spaceflight mission to a polar orbit. Liftoff is set for Monday, March 31, at 9:46 p.m. EDT (0146 UTC).
