Not a creative or innovative thought about how to repair Columbia on-orbit with the stuff they had on-board. No wonder they can't figure out how to make a repair kit for the heat shield so they can service or bring Hubble down safely. end rant Save the Hubble, from a disgraceful death, Craig Fink |

Not on the current manifest, I'm afraid. All planned shuttle flights are either to ISS or HST. They're in different inclinations so you can't visit both on the same mission. Plus, the Orbiter Docking System takes up too much room in the payload bay for HST to fit. A hypothetical mission would have to be launched in HST's orbital plane (28.5 degrees inclination) and leave the payload bay empty for HST return. The latter rules out a Spacehab-type science mission, leaving only a satellite deploy mission possible. And the space shuttle is legally prohibited from performing satellite deploys that could be done by an ELV. -- JRF Reply-to address spam-proofed - to reply by E-mail, check "Organization" (I am not assimilated) and think one step ahead of IBM. |

I think that it would be fascinating to some day be able to see the HST in the Smithsonian Air and Space Museum, and that would be easy for me as the new museum annex is less than 100 miles from where I live (Virginia); but I can't see the justification for a $500+ million shuttle mission being built around a returning the HST if the mission is not justifiable for non-HST reasons. -- Scott M.

Surely you can see the HST (or its spare), unless it's been removed? They even took a component from it for a servicing mission.

The interesting concept thread has a proposed propulsion system that could move
hubble to a near ISS orbit for easy servicing. It could then be updated indefinetely. I believe this is a excellent cost effective idea and would make retrieval easy too |

I believe this is a excellent cost effective idea and would make retrieval easy too This is completely impractical from an orbital mechanics standpoint, as well as a safety standpoint. It is cost prohibitive to move HST's inclination that much, and once "near ISS" would steadily move away from ISS without very costly maintenance thrusters, which (of course) would degrade the scientific merits for the telescope *in the first place*.

You'd be surprised. It can be made to work, though in my opinion the benefits don't outweight the costs.

Unfortunately, NASA does not seem to be taking a particularly rational
approach to saving Hubble. Goddard wants to spend $300 million on developing a robotic servicing mission. Too bad for this option that by the time the system is developed, all the Hubble gyros will likely be out of action, making a robotic mission difficult if not impossible. Johnson Space Center wants to use 2 Shuttles for a servicing mission, one for the prime mission, one as a backup in case the first Shuttle has problems inflight and the crew needs to be rescued. Since there is no way that NASA would launch a Shuttle in a few days in the wake of a possibly unknown crippling accident aboard a prior Shuttle, this 2 Shuttle option won't pass the first serious look. So, things look grim not just for Hubble but to avoid a 2nd Skylab type failure. "Scott M. Kozel" wrote in message ...
