The Amazon founder’s space company marked a major milestone Thursday with the first test flight of its New Glenn rocket.

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. Jeff Bezos flew in New Shepard on July 20, 2021, crossing the Kármán line, the dividing line between Earth’s atmosphere and outer space.

Founded 25 years ago by Bezos, Blue Origin has been launching paying passengers to the edge of space since 2021, including himself. The short hops from Texas use smaller rockets named after the first American in space, Alan Shepard. New Glenn, which honors John Glenn, is five times taller.
