SpaceX readies used rocket for space station flight

SpaceX is readying a previously flown Falcon 9 booster and an equally "used" Dragon cargo ship for launch Wednesday, one day later than planned, on a flight to deliver 4,800 pounds of equipment and supplies to the International Space Station. It will be the California rocket builder's 17th flight so far this year. The launching will mark the fourth time SpaceX has reflown a recovered Falcon 9 first stage -- a first for NASA -- and the second time the California rocket builder has re-launched a Dragon supply ship.
