Here’s an award I received when I was working on the Space Shuttle Main Engine (SSME) program back in the day. NB – This was a few years after I hired in and Rocketdyne was then owned by Rockwell International, before it was purchased by Boeing, then United Technologies, then Aerojet (current owner).
Actually, when I first hired in (after being a “job shopper”, a temp, for a little over a year), I did take a great class on how the SSME operated . . . still operates as today’s slightly modified RS-25, four of which will power NASA’s Orion spacecraft, providing 2 million pounds of thrust and working with a pair of solid rocket motors to generate a total of 8 million pounds of thrust. Orion—also known as SLS (Space Launch System)—is being built to return humans to deep space destinations, including the Moon and Mars.
