The 320-foot New Glenn rocket was supposed to blast off before dawn with a prototype satellite from Florida’s Cape Canaveral Space Force Station.

Bezos’ space company Blue Origin started at about the same time as Musk’s SpaceX but since then Musk’s firm has launched more than 400 of its Falcon 9 rockets into orbit and is testing out its giant Starship rocket which it hopes will send astronauts to the Moon and one day possibly on to Mars.

Jeff Bezos’ Blue Origin has called off the launch of its New Glenn rocket from Florida at the last minute after a “few anomalies” were found during mission countdown.
