Live coverage: SpaceX supply ship returns to Earth

SpaceX test-fired a reused Falcon 9 booster Monday at NASA’s Kennedy Space Center in Florida, checking the rocket’s readiness for a planned liftoff Saturday with an Airbus-built commercial communications satellite.

Riding into port aboard a floating platform before dawn, SpaceX’s Falcon 9 rocket booster arrived back at Cape Canaveral early Tuesday after sticking a historic landing at sea last week, kicking off a series of inspections and tests before engineers ready it for launch again.

Liftoff from Space Launch Complex 40 occurred at 7:16:10 a.m. EST (1216:10 UTC), but views of the launch were obscured by a thick blanket of fog.
