Talking of JWST, guy from Restore L fiso webcast is trying to convince JWST team to paint a pattern on JWST which makes capturing it easier. JWST is not serviceable but that doesn't stop a tug attaching its self and taking over propulsion. Could even bring it back to cis lunar station for investigation if not repair.

It's called an optical fiducial. Basically it's a very precise shape/pattern that a machine vision system can use to tell what your relative pose (angles) and position to the object are, just by looking at it. Super useful for rendezvous and capture operations, and the stickers to do so weigh only a few grams each if done right.

It is, however, optional. It just makes machine vision easier. But could be done without it.

Repair of satellites by crews at DSH could be reality. It would require likes of OA tug to haul them from GEO to DSH. Probably not financially viable for comsats but $B government satellite is different story.

Worth a few grams though, I think...?

(Snip)
Hubble should have resided at L2 like JWST and SIRTF for science
(snip)

SIRTF/Spitzer is not at L2 ;D
And don't "should" all over Hubble. It is what it is for good, and not so good, reasons.
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?
