I was assuming that GP meant "assembly in Earth orbit" and then the JWST could then rocket off on its own, fully-assembled. (Or, if they didn't mean it that way, I mean it that way.)

- bnegreve 5y ago> the JWST could then rocket off on its own, fully-assembled I am no expert, but this has to be quite a challenge. How much fuel do you need to do that?
- lmm 5y agoNot much. There's a saying that once you get into orbit you're "halfway to anywhere", and required fuel is exponential in required delta-v. Just look at the sizes of the 3 stages of the Saturn V for a comparison point.
