The Artemis SLS is the latest and greatest rocket from NASA and more powerful than anything yet flown into space. And yet for all of its modernity for the upcoming moon missions and its competitors like SpaceX and Blue Origin concentrating on reusability, NASA will be throwing away four of possibly the best reusable engines yet made, the RS-25 with each launch just like they did in the 1960s & 70s with the Apollo mission and the one time use F-1 engines. So in this video, we look at how the RS-25 came about and why it’s now a disposable item.
