At 04:35 UTC, the Falcon 1 lifted off from Omelek Island. The live video feed of the launch was cut off 140 seconds into the flight, at which time it was announced an anomaly was detected on the vehicle. The fate of vehicle, whether it was destroyed or if it successfully entered low Earth orbit, is not known at this time.[21][22].

Members participating that the SpaceX camp have been twittering that there was a loss of the vehicle during the separation stage, which resulted in the engine exploding.
