Live coverage: SpaceX supply ship returns to Earth

A Falcon 9 rocket booster — under the power of a single Merlin 1D engine — descends toward a specially-outfitted ocean landing platform off Florida’s East Coast on Tuesday in a brief video clip released by SpaceX.

The addition of these latest satellites will boost the growing constellation to nearly 5,900. Liftoff from Space Launch Complex 40 happened at 6:08 p.m. EDT (2208 UTC).

A SpaceX Falcon 9 launcher rocketed into orbit Friday from Vandenberg Air Force Base in California, climbing away from a hillside launch complex just after sunrise with 10 Iridium communications satellites.
