Bezos’ Blue Origin plans 21st century rocket engine The Seattle Times

Capping back-to-back news that emphatically heralded the United States’ return to space exploration, Jeff Bezos on Wednesday unveiled plans for “a 21st century” rocket engine developed by his private aerospace company that could help reduce Russia’s role in U.S. orbital flights.
At a news conference at the National Press Club in Washington, D.C., Bezos showed off a model of the BE-4, a liquid-propellant engine that will be used to power new version of the Atlas rockets now used to launch telecommunications and spy satellites and other payloads into space.
The BE-4 will be jointly funded by Bezos’ Kent-based Blue Origin and United Launch Alliance, a 50-50 venture between Boeing and Lockheed Martin. Work on the liquid oxygen, liquefied natural-gas engine has been under way for three years in Kent and in West Texas, and four more years of development are expected before first flight.
