SpaceX is awaiting a launch control decision on another attempt to try and launch the Falcon 9 rocket later today following an agonizing automatic shut down of the vehicle in the last second before launch at around 1.30 EDT.
Space X says an unspecified “out of limits” start-up parameter was the cause of the shut down. The clock has been re-set to T-15 minutes and it's back to the waiting game. The company is now standing by for a new T-zero time from mission control.
Still waiting.... Falcon 9 on the pad (SpaceX)
