An unmanned Dragon space capsule with 900 kilograms of cargo splashed down in the Pacific Ocean, SpaceX reported on Sunday evening.

The spacecraft splashed down in the Pacific Ocean about 400 kilometers west of Southern California at 12:22 p.m. PT.

The Dragon is a reusable spacecraft developed by SpaceX to fly cargo to the ISS after NASA retired its space shuttle fleet last year. Dragon is the only space station cargo craft capable of returning a significant amount of supplies back to Earth, including experiments.

Dragon was launched atop a Falcon 9 rocket on October 7 from Cape Canaveral Air Force Station in Florida, beginning NASA's first contracted cargo delivery flight to the station.
