Not only will pointing the ST at earth damage some of its sensors,
but there's a possibility that looking at bright debris in earth
orbit could damage one of the more sensitive detectors.  The
article I read that in points out that in the 17 year lifespan
of the telescope there's a good chance it will be hit by a millimeter
sized chunk of orbital debris or meteor (and about a 1% chance of
a collision with a large chunk that would nearly certainly destroy
the satellite).  Much larger scopes will have to be built in high
orbit.
