Dragon brings Chinese experiment to Earth

LOS ANGELES - California-based SpaceX confirmed on Monday that its reusable Dragon capsule successfully splashed down in the Pacific Ocean, marking the first time a private spacecraft has flown to and from the International Space Station more than once.

The company reported the achievement via Twitter: "Good splashdown of Dragon confirmed".

Dragon first flew in SpaceX's fourth resupply mission to the space station in 2014. This time, it's returning more than 1,860 kilograms of cargo, including items from human and animal research, biotechnology studies, physical science investigations and education activities.
