Thus rendering HST at L1 a useless pile of junk. "Shaking" of any kind is
not acceptable in HST's current deployed condition. Activities by EVA
astronauts during repair flights were *strictly* limited as to contact with
HST.

Yes, but Hubble made it through a shuttle flight to orbit ok. Is there
any way to remotely 'undeploy' the vulnerable components, like solar
panels? What components are particularly vulnerable?

The alternate plan if astronaut presence is required to stow Hubble
for boost is to remotely attach a small ion thruster or tether system
that can GENTLY move it to a higher orbit as a temporary measure, (to
revent unplanned reentry) until such time as astronauts can visit (in
a CEV or whatever) to get it ready for transfer to L1.

Would Van Allen radiation do anything to the optics or CCDs?
