If we can't even justify servicing Hubble that means that the shuttle program is now completely dead. There is no other mission that could possibly be as important scientifically.
Of course everyone knows that the shuttle is dead, 14 dead people in two separate disasters mean that it won't be going back. But instead of facing up to that fact NASA will continue to burn money on projects that are meant to disguise the fact. The announcement of the Mars mission being an example, Bush announced the Mars mission as a way to cover the fact that shuttle was going to be all but terminated. The problem is that 'all but' part. Don't want to end all those jobs with contractors making juicy donations to the GOP, particularly not Halliburton.
There is a real failure of leadership here. Instead of saying it as it is we have a Karl Rove PR job that in effect will cost the tax payer a couple of billion dollars in futile attempts to fix a shuttle that no President is ever going to let fly again.
As for Hubble, the cheapest solution is probably to deorbit the current one into an ocean and send up a completely new Hubble. We already have a mirror for the thing, and it does not have spherical abberation defect. Kodak made a standby mirror for use in tests that they did not want to risk the real one on.

The concept seems so simple, but the reality is much more complex. IANARS (I am not a rocket scientist), but orbital mechanics just don't work at all like you're used to things working on earth (or in Star [Trek|Wars]).
For one thing, if you give an orbiting object a push "up", that doesn't send it away from the planet! It just puts it in a higher orbit, and probably an elliptical one at that. An ellipse (oval) seems fine, but the Earth probably is at a focus, not the "center". If you've lowered the close point (perigee?) into the atmosphere, you've got big trouble.
Hubble simply doesn't have the sort of thruster that could boost it into a higher, more stable orbit. There are proposals to strap on a booster to do that job, but you've either got to send someone up to attach it, or find a foolproof way of doing it robotically. Remember, Hubble wasn't designed to be reboosted by anything but the shuttle!
And things go wrong -- remember the time the Shuttle crew had to build a flyswatter-looking thing to flip a switch on a satellite they'd just launched. More recently, of course, there's Mars, the Ship-Eating Planet.

This shows the resources for manuevering the telescope are already budgeted. There may be added expense in engineering a mount point on the ISS, and additional risk & effort involved in calculating a safe vector, but as the following (kick ass) tools [nasa.gov] can show you, the HST and the ISS have practically identical orbits assigned them. The difference in orbits between the ISS and the HST are in almost identical orbits, as regards altitude, speed and direction of travel. It would be simple and cheap to re-purpose the end-of-life booster pack to serve as a tow truck into ISS space.
What problems would this plan solve? Well, service missions are suddenly a matter of popping out on the patio and replacing a fuse, instead of a multi-billion dollar voyage risking the life and safety of many billions more worth of equipment, personel and reputation. Extra parts can be tucked in with ISS mission carry-on baggage if necessary. and the HST would still be one of the finest optical instruments ever imagined.
Would there be problems with this solution? Yes. There may be issues with local radiation effects in the vicinity of the station, effects that might diminish the sensitivity of the instrument, whether by heating, light-polution, communications equipment or even vibration from the motors used aboard the station. The HST was not designed to work under such conditions. However, many of these issues can be solved with careful consideration with engineering the mount point spar. Any remaining degradation is worth the pain, as a hobbled hubble is better than a scrubbed hubbled.
This solution is just the first off the top of my head. There are others to consider. Perhaps they could use the booster to park the HST in a non-decaying orbit long enough to wait on the arrival of cherap space flight. On second though, by the time we have cheap space flight, it will be a simple thing to put up copies of the HST and far more besides.
