New Method Discovered For Making Telescopes On the Moon 135
NASA scientists have discovered a way to craft very large mirrors using carbon nanotubes, some epoxy, a little bit of aluminum, and large quantities of lunar dust. They say the technique will allow the construction of massive telescopes on the moon without the expense and risk of transporting the mirrors from Earth. Douglas Rabin of the Goddard Space Flight Center is quoted saying, "Our method could be scaled-up on the moon, using the ubiquitous lunar dust, to create giant telescope mirrors up to 50 meters in diameter." While this breakthrough was relatively cheap, NASA is currently offering up to $10 million for other good lunar research projects.

If it is build on the moon, it can be much larger than anything that can be carried up in one shot on a rocket.
It doesn't need to be periodically boosted back up into a higher orbit.
Plenty of real estate for large solar arrays/backup systems.
If it is part of a permanent manned outpost, astronauts will be on-hand to do repairs promptly.
Stable surface to stand on means that fragile gyros and limited fuel are not needed.
There are probably more good reasons
