Taxpayers lost $110 million when a SpaceX rocket carrying cargo to the International Space Station disintegrated shortly after liftoff last month, a NASA official said at a Friday hearing.

“That’s gone,” said William Gerstenmaier, a NASA associate administrator, of the money lost when the SpaceX rocket failed on June 28 far above Florida’s coast.

The Hawthorne, Calif.-based company is leading an investigation into the cause of the failure.
