How feasible is a repair mission without the shuttle?

[twistedpair]

L2 is very far from earth, well beyond the Moon. The Shuttle could never leave Low Earth Orbit, so it's a non-factor in repair missions once JWST is on station.

I believe what was GP was getting at is that even in a "convenience orbit", a repair mission would be very unlikely.

The scenario we're talking about is having JWT unfold in Low Earth Orbit, so it can be repaired there, if need be.

in Armageddon the Shuttles flew over the moon

The shuttle-like craft were explicitly special, more capable craft (visually hinted at by the extra set of boosters and other design differences.)

Not that Armageddon was particularly focussed on reality.
