Blue Origin made two adjustments in quick succession to its schedule for launching its New Glenn rocket to orbit for the first time.

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.

The company, started by the Amazon founder Jeff Bezos, reset its countdown clock repeatedly over a period of just over two hours before eventually postponing the test flight to another day.
