I agree with RogueOne on virtually nothing, but he’s hit a real problem. NASA’s coffers are not unlimited, and most of the arguments presented about it are that JWST is too big to fail. I’m highly conflicted about that. I personally feel that JWST was at least partially knowingly sold to its own community as a lowballed bill of goods, and has resulted in unnecessary pain and sacrifice within NASA, robbing Peter to pay Paul on numerous occasions.

If we could cannibalize JWST equipment and advances and divert them to other more ready-to-go missions, I’d axe it in a heartbeat. But I don’t think that’s possible. Make no mistake JWST has damaged NASA, and it will take quite a lot just to undo that. JWST’s science return had _better_ be everything they hope and more, or it will be a worse black eye for NASA - and its future budget, and the community of science and infrastructure support - than Hubble ever was.
