The SpaceX CRS-9 Dragon cargo craft departed the International Space Station Aug. 26 after five weeks at the complex. Dragon delivered critical science experiments and the first International Docking Adapter to which U.S. commercial spacecraft will link up to in the future. Using the Canadarm2 robotic arm, Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins released the Dragon and monitored the resupply spacecraft as it backed away to a safe distance from the station for its deorbit engine firing that would enable the ship to enter the Earth’s atmosphere for a parachute-assisted splashdown in the Pacific Ocean west of Baja California. Dragon returned about one and a half tons of science experiments and other cargo that will be collected once it reaches port in Long Beach, California. Dragon launched July 18 atop a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida and arrived at the station July 20.
