Dragon CRS-3

SpaceX DragonThe third SpaceX Dragon unmanned resupply mission to the International Space Station lifts off, testing a new version of SpaceX’s Falcon 9 booster rocket which incorporates landing legs and an attitude control system designed to return the booster’s first stage safely to Earth for possible reuse. The attitude control system succeeds in cancelling out the booster’s roll and brings the first stage down for a controlled splashdown in the Atlantic Ocean. The Dragon capsule goes on to dock with the ISS two days later.
