For the first time, aerospace company Blue Origin has fired up a brand-new engine the company developed for its future Moon lander. The engine, dubbed the BE-7, ignited for a full 35 seconds during a test at NASA's Marshall Space Flight Center. It's a big step for the company as it prepares to build its lander, named Blue Moon, and eventually send it to the lunar surface.
Blue Origin founder Jeff Bezos tweeted out a video of the test last night. The recording shows flames coming from the engine horizontally, first appearing bright
First hotfire of our #BE7 lunar landing engine just yesterday at Marshall Space Flight Center. Data looks great and hardware is in perfect condition. Test went full planned duration – 35 seconds. Kudos to the whole @BlueOrigin team and grateful to @NASA_Marshall for all the help! pic.twitter.com/cTjjrngumY
