Video: Space station’s robot arm captures Dragon cargo ship

A cache of critical cargo stowed inside a solar-powered Japanese resupply freighter is speeding toward a rendezvous with the International Space Station after a successful launch Wednesday.

Although recovery teams in the Atlantic Ocean have retrieved wreckage from Sunday’s Falcon 9 launch failure, the best clues to the cause of the crash lie in raw data transmitted from the rocket as it disintegrated, SpaceX officials said Wednesday.
