The price to build a new much more advanced space telescope and
launching it probably cost less than the cost to repair and update the
Hubble using the shuttle.

If they don't want the Hubble to be burned up and instead wanted it as
a preserved historical relic, I suggest taking it down with the
shuttle and then stored it into the museum, along with the shuttle.

That was the plan that was scrapped. Bring it back, examine it for the long
term effects of space and give the bits to the Smithsonian.
