A SpaceX rocket carrying supplies to the International Space Station erupted Sunday shortly after liftoff.

NASA says the accident confirmed a few minutes into the flight from Cape Canaveral, Florida. Pieces could be seen falling into the Atlantic.

NASA commentator George Diller says "the vehicle has broken up." He says it was not clear how the disaster occurred.

This is the second failed station shipment. In April, a Russian cargo ship spun out of control and came down. And last October, another company's supply ship was destroyed in a launch accident.

SpaceX says the initial part of the liftoff went well, until the vehicle went supersonic.
