A huge rocket booster that's been built to help get Nasa's next shuttle into space has been successfully tested.

It was fired up for two minutes in the Utah desert in America.

Nasa says it's the largest and most powerful solid-fuel rocket motor that's ever been designed for flying.

The booster has been made as part of a programme hoping to take astronauts back to the moon. Watch it fire up here!
