I sorta agree with how it panned out though; if you're going to go to all the trouble to send a shuttle up there anyway, you might as well do a servicing mission.

I still think they should have brought it back, it was the first of its kind and is an invaluable piece of astronautical history.

Brought it back this past mission?  I heartily disagree.  There's still a massive amount of science it's going to be able to achieve in its newly-repaired state, and the myriad of innovative techniques developed for this maintenance will prove invaluable in the long haul as we start to work in space to a greater extent.  (Who knew astronauts could work with tiny screws, for instance?)  I'd love to see it returned here at the end of its life, were there any way to do so, but it definitely still belongs up there right now.

No, not now, I mean when it is finally ready to be retired. It deserves better than to burn up.

They should piggyback it to moon, the next time they pay a visit.

Orbital mechanics doesn't work like that.

The only options open are to:

1) Keep re-boosting it every 5-10 years until it can't hold itself still enough to be captured (eg the reaction wheels fail). At this point it becomes a permanent hazard to navigation, and will also be extremely hard to get rid of as it can't be 'grabbed' and either repaired or dropped.

2) Some time after the replacement telescope goes up, cremate it into the upper atmosphere as a glorious meteor across the sky.

Bring it back and put in London's Science Museum. We've already got Charlie Brown (Apollo 10 CM). I would be fantastic to have hubble

Well, it's possible to do, but not with our current capability.  Getting to the moon from low earth orbit requires delta v (change in velocity) of 4.1km/s, with an additional 1.6km/s if you want to actually land on it.  That's a hell of a lot of extra thrust if you're lugging 11,000 kilos of hubble with you. <_<

So speaking of Hubble, NASA just released some new images taken with the refurbished and newly-installed instruments from the servicing mission.  Looks like all of that hard work payed off in spades.
