Having been loaded and having had its hatch closed the day before, the SpaceX Dragon CRS 3 cargo spacecraft was un-berthed by the Space Station robot arm Canadarm-2 at 1200 GMT on 18 May 2014 and fully released the same day at 1326 GMT. The craft made a deorbit burn from 1812 to 1822 GMT with the separation from its trunk carrier device at 1824 GMT. Dragon CRS 3 re-entered at 1845 GMT with the resulting parachute splashdown occurring west of Baja California at 1905 GMT. It was subsequently found that similar to the Dragon CRS 1 mission, the capsule had sprung a leak letting sea water into the craft. Dragon’s return cargo included a spacesuit with a faulty cooling system – EMU 3015 and some experimental samples, none of which was harmed by the leak.
