Watch our interview with two International Space Station astronauts

SpaceX will make its latest attempt following scrubs due to ground systems issues and then poor weather. Liftoff from Pad A at Starbase is scheduled for 6:30 p.m. CDT (7:30 p.m. EDT / 2330 UTC).

Watch replays of the launch and docking of the Soyuz MS-05 spacecraft Friday with three new crew members for the International Space Station.

Construction crews at Cape Canaveral’s Complex 40 launch pad are busily repairing and upgrading the facility after a SpaceX Falcon 9 rocket exploded there last year, with the pad’s return to service scheduled before the end of the summer, clearing the way for final preparations for the triple-core Falcon Heavy’s maiden flight late this year.
