Blue Origin, the rocket company Amazon billionaire Jeff Bezos founded, notched one of the most substantial successes in its history on Thursday: sending a rocket to orbit.

Blue Origin will try, try again to launch its heavy-lift New Glenn rocket to orbit for the first time — if the Florida weather cooperates.

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.
