Is there something inherently more difficult about servicing satellites in the 2nd Sun-Earth Lagrangian point?

One part of the original question asked, "...servicing JWST would be more difficult than achieving Low-Earth Orbit, but less difficult than landing on the moon, despite the moon being about 1/4 ...

Is there something inherently more difficult about servicing satellites in the 2nd Sun-Earth Lagrangian point?

Apart from the distance (which creates issues for manned crews and large time lag for unmanned probes) there are a couple of other issues: L2 issue: L2 is unstable (It's like trying to keep a ball on ...

Is there something inherently more difficult about servicing satellites in the 2nd Sun-Earth Lagrangian point?

I could add to previous answers, that we have really big loss with the retirement of the Space Shuttle, even considering its costs and limitations. The Shuttle was the only[1] space ship capable of ...

Is there something inherently more difficult about servicing satellites in the 2nd Sun-Earth Lagrangian point?

For servicing the JWT with humans, an almost certain requirement, I would consider a tug to bring the telescope to LEO, where humans are much more protected from radiation and their mission would be ...

Is there something inherently more difficult about servicing satellites in the 2nd Sun-Earth Lagrangian point?

Distance certainly is a key factor. It took JWST a month to go from launch to L2 pseudo-orbit insertion. Another key factor is that to date, the only successful satellite servicing missions have been ...

Is there something inherently more difficult about servicing satellites in the 2nd Sun-Earth Lagrangian point?

Getting to L2 in a timely fashion is more challenging than going to the Moon. The Apollo missions took about 3 days to get to the Moon. 4.5 days is how long the LRO took to orbit the Moon when ...
