I know the RS-25 engines[0] (aka SSME, Space Shuttle Main Engine) were "reusable" in an academic sense (needing a ton of refurbishment after each use) but it hurts my heart that we're dropping them in the ocean and it makes it hard for me to feel good about the Artemis program. It's irrational but it makes the kid who loved the Space Shuttle (which, itself, was a political pork barrel and a jack-of-all-trades-master-of-none kind of program) sad.

They are functionally obsolete. Chances that we’re still using SLS in ten years is slim. Any resources going towards refurbishment are better spent on Starship and Blue Moon.

You and me both. They don’t even put a parachute on the boosters to get them back. Some pieces on these boosters have been in use since the 80s.

		And all of that reuse was so expensive that it set back reusable rocketry for decades as the common wisdom said it was uneconomical - even after it was demonstrated that you could have reuse without expensive refurbishment.
