CAPE CANAVERAL, Fla. — The SpaceX Falcon 9 rocket is ready to fly again.
CEO Elon Musk said the rocket was not damaged during its launch and return to Earth last month.
The Falcon 9's last flight is a remarkable technical breakthrough, as the rocket landed upright.
Landing rockets upright cuts the cost of space travel since the rockets can be reused instead of discarded.
SpaceX said it will continue to test the Falcon 9 rocket to determine its condition.
