Why not skip all future Shuttle missions (skipped anyhow for safety reasons) and possibly also the booster add-on that was discussed recently. Imagine how much you can build with that money using modern technology. Remember, Hubble was designed in the seventies, built in the eighties and then left to rot for some years in a cleanroom. It has one big heavy mirror and was designed to be transported and serviced by the shuttle. Note that a typical shuttle launch costs > 600M$. A remote controlled rocket pack that attaches to Hubble wouldn't be cheap either.

    Now think what you could build with that money in todays technology. I would suggest reusing some of the detectors designed for the next service mission. Use a modern light-weight mirror. No options for repear in space, just launch and forget. If it blows up, build another one. Mightbe be really modest in your goals, don't go for a design that is 10 times better than hubble, but try to equal it with a mirror of 1.5 - 2 meter.

    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.

  19. Hubble: A solution by MOMOCROME · · Score: 4, Interesting
    I've got the solution to our Hubble Troubles: lash that bugger to the ISS.

    It's simple, really. To sink the Hubble, NASA already plans on firing off an un-manned mission to drive it down into a decaying orbit:
    The Hubble will eventually fall out of orbit and crash to Earth, probably in 2011 or 2012. To make that event safe, Grunsfeld said, NASA will design and build a small robot craft that will be launched and guided to the Hubble.

    The robot craft would "grab the Hubble and bring it into the atmosphere in a controlled manner," he said, guiding the school-bus-sized craft to harmlessly splash into a remote part of an ocean.

    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 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. I suppose there are other possibilities, but mating the HST to the ISS is the cheapest, fastest, safest and sanest choice for the immediate future.

It's freely available (after a 1 year period that the PI has exclusive access to it) and astronomers from Pakistan to Brazil have been using it.
