I believe there is a Shuttle Flight manifested for late next year that
will visit the Hububle (uh, I mean Hubble) telescope. From what I've
heard, the chances of success are pretty good. The defect in the scope's
mirror is said to be 'perfect', so I *think* they'll just have to replace
the main CCD camera with one of a different focal length.

If I were the Dictator of NASA (yeah, right) I would send EVA god
Jerry Ross to do the actual switchout.

I am severely ignorant on this matter...

My guess is that glass was chosen because it is less susceptible to thermal
deformation. Plus, it is much easier to work with than Aluminum. 

I think the mirror is coated with a micro-thin layer of aluminum.
