SpaceX landed its unmanned rocket on a seaborne platform Friday, the first success after four failed attempts to get the rocket launched and then returned, unscathed, to a floating landing pad. The Falcon 9 rocket launched from Cape Canaveral at 4:43 p.m. with the SpaceX Dragon cargo ship, bound for the International Space Station.
