Shields Up
So put a covering around it. That will protect it from
the little particles at least. If we are going to send a
rocket booster there to attach to it, might as well put
a shield on it as well.
Then again, letting it get hit will tell future explorers a
lot about the amount of debris in our region of the Sol
system.
I'm starting to feel that, as much as the Hubble has done,
I would rather spend our money and resources on bigger
and better telescopes.
