Video: Change of command aboard International Space Station

The Orbital ATK’s Cygnus commercial resupply spacecraft, named the SS Deke Slayton II, is packed up and poised for launch to the International Space Station.

A commercial resupply freighter owned and operated by SpaceX wrapped up a two-day trip to the International Space Station on Wednesday, delivering a new docking port and two tons of other equipment to research laboratory more than 250 miles above Earth.

A Northrop Grumman Antares rocket, upgraded to carry heavier payloads into orbit, lifted off Saturday from a launch pad on Virginia’s Eastern Shore with a Cygnus supply ship in pursuit of the International Space Station with fresh food, a collection of biological and technology demonstration experiments, a zero-g baking oven, and repair gear for an aging $2 billion particle physics experiment.
