Video: Change of command aboard International Space Station

Carrying more science research gear to the International Space Station than ever launched before by U.S. commercial logistics vehicles, the next Orbital ATK Cygnus freighter takes flight Tuesday.

SpaceX is targeting April 8 for the launch of its first resupply run to the International Space Station in nearly a year, a mission that the company hopes will mark the start of a rapid-fire launch manifest full of payloads waiting to fly.

Flying with a reused first stage and a recycled Dragon supply ship, a SpaceX Falcon 9 rocket lifted off from Cape Canaveral on Friday bound for the International Space Station on an unpiloted cargo delivery mission.
