Sending a spacecraft to the space station has only ever been accomplished by four entities – the United States, Russia, Japan and the European Union.
Saturday’s launch was aborted when the flight computer detected slightly high pressure in the engine 5 combustion chamber. During rigorous inspections of the engine, SpaceX engineers discovered a faulty check valve on the Merlin engine.

SpaceX will webcast the launch live at www.SpaceX.com starting at 3:00 AM Eastern.
