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 uncrewed New Glenn rocket took off at 2:03 a.m. EST from Complex 36 at Cape Canaveral Space Force Station, Blue Origin said.

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.
