Fortune Magazine ran this story and I thought my readers may have missed it.
It’s a way to quickly build a cheaper engine for a potential Mars lander.
For three years the National Aeronautics and Space Administration has been testing a variety of 3D-printed rocket engine parts. But in a recent test, NASA has come closer than ever to building an entire rocket engine—one that could potentially power a Mars lander—solely from additive manufacturing.
Turbopumps, injectors, and valves are engine parts that work together to get a rocket airborne, and they represent about 75% of the parts needed to build a 3D-printed rocket engine. NASA has 3D-printed and tested all three individually with great results, as Fortune has previously reported.
