Blue Origin called off the debut launch of its massive new rocket early Monday because of technical trouble. 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.

Blue Origin had to postpone the first-ever orbital launch of its heavy-lift New Glenn rocket due to a technical glitch.

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.
