A SpaceX-owned Dragon cargo craft left the International Space Station on Friday and flew back to Earth for a parachute-assisted splashdown in the Pacific Ocean with a dozen mice and more than 3,000 pounds of experiment specimens and space hardware.

Watch the launch of a commercial Falcon 9 rocket carrying a Dragon cargo ship bound for the International Space Station, as seen live on NASA Television.

A two-stage Northrop Grumman Antares rocket rolled out of its horizontal integration facility Monday for the mile-journey south to launch pad 0A at the Mid-Atlantic Regional Spaceport in Virginia, where liftoff on a space station resupply mission is scheduled for Wednesday.
