> Because the SLS uses left over Space Shuttle engines. Once. The reused RS-25s aren’t the same as the ones that flew on the STS-1. STS-1 used the original RS-25, Artemis uses RS-25D, and will in future use the new RS-25E. In the same way, if Saturn V survived to the present, we wouldn’t be using the original F-1s/J-2s any more, we’d be a using significantly enhanced versions-and the originals would be infeasible to manufacture due to component availability changes |
