On March 25, 2013 the space station astronauts closed the hatches leading into the "Dragon” unmanned supply spacecraft. On March 26, 2013 the station's robotic arm removed the capsule from a berthing port on the complex. Controlled by ground controllers and then astronaut Thomas Marshburn, the robotic arm let go of the "Dragon” resupply vehicle at 10:56 UTC. On March 26, 2013 at 16:34 UTC the "Dragon” capsule splashed down in the Pacific Ocean at about 360 kilometers west of Baja California, Mexico. Dragon's return date, originally scheduled for March 25, was postponed due to bad weather near its targeted splashdown site in the Pacific Ocean. The Dragon delivered to Earth about 1200 kilograms (2668 pounds) of cargo. It was the "SpaceX CRS-2” mission. CRS means Commercial Resupply Services.
