Thanks for mentioning the GRAIL mission, but I don't think the spacecraft(s) would be in line of sight between us and the moon. Taking a three month
long trip to the moon would be a highly elliptical flight path, if detectable they wouldn't be near the moon from our perspective until they achieve
lunar orbit or very close to. Even a fast trajectory like the Apollo's took wouldn't get the spacecraft near the moon in our line of sight its whole
path. I'm not sure they show the GRAIL flight path, they have a fairly decent one of JUNO, and if you could see JUNO, you wouldn't get JUNO and
Jupiter in the same field of view until it got there.
Anyway I'm not sure what kind of power a telescope would have to be to see a lunar satellite. LRO is orbiting very close to the lunar surface,
slightly elliptical, but to see it I would think the outline of the moon would have to be nearly a straight horizon, and not a several hundred mile
curved area. The moon is 2,160 miles in diameter, the LRO is like 20 feet, or the size of an SUV, actually a large satellite by comparison.
