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 has launched its New Shepard rocket—a reusable sub-orbital rocket used for space tourism—27 times. It's named after Alan Shepard, the first American in space. Bezos flew in New Shepard on July 20, 2021, crossing the Kármán line, the dividing line between Earth’s atmosphere and outer space.

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.
