Earlier this year, Blue Origin's founder Jeff Bezos promised to unveil details about his company's orbital rocket "later this summer," and on Monday morning he delivered. In an e-mail, Bezos released some preliminary details about the "New Glenn" rocket which will employ seven of the company's next generation BE-4 rocket engines, making for a powerful rocket indeed. The rocket is named for the first American to reach orbit, John Glenn.
According to Bezos, the two-stage variant of New Glenn will measure 23-feet in diameter and stand 270 feet tall, with a sea-level thrust of 3.85 million pounds. The engines will burn liquefied natural gas and liquefied oxygen. The three-stage variant of New Glenn will be 313 feet tall, with a single BE-3 engine powering its upper stage. "New Glenn is designed to launch commercial satellites and to fly humans into space," Bezos wrote. "The three-stage variant—with its high specific impulse hydrogen upper stage—is capable of flying demanding beyond-LEO missions."
Blue Origin, which is in the midst of building launch and production facilities at Cape Canaveral, Florida, plans to fly New Glenn for the first time by the end of this decade, Bezos said. The new rocket and its engines, like the smaller BE-3 and New Shepard Propulsion module upon which it is based, will be reusable. The first stage of the booster is being designed to fly a minimum of 25 missions. This does not seem an idle boast, either, as Blue Origin has already flown and landed a single New Shepard rocket four times.
