In principle that's possible. In practice, the buyer would assume the
liability by indemnifying the government against damage claims, then taking
out an insurance policy to cover the risk of that indemnification. But if
the buyer doesn't have a credible plan to prevent an uncontrolled deorbit
of HST, the insurance company is likely to charge exorbitant premiums.

Fine and good, but HST is gradually losing the gyroscopes that allow it to
point accurately enough to get good pictures. NASA projects that the
telescope will fail by around 2007 if no servicing mission is performed. It
will remain in orbit quite a while after that - NASA projects that its
orbit won't decay until 2013. Of course, NASA also projected that Skylab
wouldn't decay until 1981. Orbital lifetime predictions spanning a solar
maximum are still a rather inexact science, I'm afraid.
So, to throw it back at you, let's say I'm an underwriter at MuttLife
Insurance Co. and you're the proposal lead for the Micro$loth Space
Telescope Purchase team. I ask how you plan to service HST, so that you can
1) prevent it from deorbiting uncontrollably, and 2) keep it producing
pictures so that you can generate enough of a revenue stream to be able to
afford the insurance premiums I'm about to charge you.
What's your answer?

I take it that, by posting this to sci.space.history, you consider that HST
is already history? :-)
