Video: Soyuz MS-01 leaves the space station for landing

A Japanese resupply freighter and its H-2B rocket booster rolled out of the vehicle assembly building at the Tanegashima Space Center just before sunrise Friday for the half-hour trip to the launch pad.

A rocket booster SpaceX used to launch a planet-hunting NASA observatory two months ago fired again Saturday at Cape Canaveral, clearing a major pre-flight checkout before blastoff June 29 with a space station supply ship.

Four days before its scheduled blastoff on a resupply run to the International Space Station, a Falcon 9 rocket ran through a countdown rehearsal and engine test Sunday at NASA’s Kennedy Space Center in Florida.
