Tomorrow, Tuesday, May 22nd, at 3:44 AM Eastern, Space Exploration Technologies (SpaceX) will attempt to launch a Falcon 9 rocket carrying a Dragon spacecraft to orbit in an exciting start to the mission that will make SpaceX the first commercial company in history to try to send a spacecraft to the International Space Station.
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. The failed valve was replaced on Saturday and after thorough analysis the vehicle has been cleared for launch.
SpaceX will webcast the launch live at www.SpaceX.com starting at 3:00 AM Eastern.
