Amazon.com Inc. Chairman Jeff Bezos, renowned for keeping quiet about strategic goals for his fledgling space company Blue Origin LLC announced plans for a reusable rocket named after 1960s astronaut John Glenn.

The New Glenn rocket would feature seven main engines and stand more than 310 feet tall. It could fly by the end of the decade.

Jeff Bezos, who leads not only Blue Origin but also Amazon, says his planned rocket “is designed to launch commercial satellites and to fly humans into space.” He says that a three-stage version and its hydrogen-powered engine “is capable of flying demanding...missions” beyond the relatively low orbit of the International Space Station.

Material released by Bezos is reported by news sources to indicate that the rocket’s size would rival the Saturn V, which helped the Apollo astronauts reach the moon. Its engines are slated to put out less maximum thrust than SpaceX’s Falcon Heavy rocket, which uses 27 main engines.
