Live coverage: SpaceX supply ship returns to Earth

Mike Suffredini, manager of NASA’s International Space Station program, is stepping down after 10 years overseeing the lab’s final assembly and transition to post-shuttle operations, the agency said Wednesday. Kirk Shireman, deputy director of the Johnson Space Center, will take over as program manager.

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).
