The JWST is about three times further than the furthest a human has ever been from earth, which was on the moon.

So, it would be __really__ hard for astronauts to swap an SSD.

It's much easier to get there and fix JWST than it is to land on the moon though.

Because the landing part was the hardest and take more delta V than actually getting to JWST. Not to mention going back from moon surface.

Didn’t JWST use some kind of grivitational breaking to stop at the LGPoint? A manned mission would require much more fuel to shorten the time of the trip and fuel for returning.

I think the engineering that would go into a mission to do maintenance/repair would be quite valuable and help with many other missions. It’s far enough to be far, but not so far that other factors like communication is extremely delayed. Getting that far out of LEO has a huge set of new challenges, I assume, we should be able to learn about.
