Dragon launched with a freezer to ferry medical research samples to and from the outpost. It was launched with ice cream inside, a rare treat for an orbiting crew.
Once the capsule is attached to the station, astronauts will begin unpacking the food, clothes, science experiments and science gear inside and filling it up with about a ton of cargo and experiments that needs to be returned to Earth.
Dragon is due to remain berthed at the station for 18 days, then parachute down into the Pacific Ocean for recovery. It will be the first large load of items to come back from the station since the space shuttles were retired last year.
SpaceX is one of two firms hired by NASA to fly cargo to the station, restoring a U.S. supply line to the orbital outpost following the end of the shuttle program. The second company, Orbital Sciences Corp., plan to start flights to the station next year.
