I think I'm going to genuinely cry the day they deorbit Hubble. Maybe it doesn't make financial sense but if there was ever an instrument that deserved to be retrieved and given a hallowed place in a museum, Hubble is it.
The original plan was that it would be de-orbited aboard the Shuttle and put in a musuem.
I'm not sure what the current plans are, but the last servicing mission installed the Soft Capture Mechanism, and the current understanding is that an uncontrolled re-entry would pose an unacceptable risk to human life. So, it seems like there is still a chance to put it in a musuem.
