SpaceX’s Falcon 9 rocket broke up in flight this morning after launch from Cape Canaveral. The launch failure destroyed a Dragon cargo ship headed for the International Space Station.

It’s not clear exactly what happened at this point. The vehicle appeared to break up near the end of the first stage burn. It’s not clear whether the vehicle broke up as a result of a failure, or whether the flight was terminated by the launch range officer on the ground after it started to go off course.

This is the third failure of a supply ship to the International Space Station in eight months. This could place the crew in a precarious situation in terms of supplies.

This was the 19th launch of the Falcon 9. All previously launches had successfully orbited primary payloads. On one launch, a secondary payload was placed in the wrong orbit.
