Blue Origin successfully launched the rocket after an attempt earlier in the week was scrubbed. The flight is a crucial test of the company’s ability to compete with Elon Musk’s SpaceX.

Nearly a quarter century after Jeff Bezos founded Blue Origin, the rocket company is poised for its most defining moment to date: sending a vehicle to orbit for the first time.

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.
