It's the last round-up for the people's telescope. Next August, after 20 years of hype, disappointment, blunders, triumphs and peerless glittering vistas of space and time, and four years after NASA decided to leave the Hubble Space Telescope to die in orbit, setting off public and congressional outrage, a group of astronauts will ride to the telescope aboard the space shuttle Atlantis with wrenches in hand...

[snip] If the mission succeeds, Hubble should be in peak observing condition until its replacement, the James Webb Space Telescope, is launched in 2013... Some argue that repairing Hubble is pointless, since ground-based observatories have overtaken its capabilities. But terrestrial telescopes fall short of HST’s resolution by a factor of 10 or more.

There are few more interesting things in space to watch than a hubble repair mission, I need to schedule a vacation for this mission.
I remember for years, the leaders of NASA said “It can’t be done...it can’t be done...to risky...too much money...it can’t be done.”
Then, NASA gets a new head guy, and suddenly it can be done.
I think that what made them change was that they bowed to the enormous pressure from the public. The Hubble is the greatest visible on-going success story that NASA has had since the launch of the shuttle. They were going to mothball the most popular — and perhaps the most valuable — project associated with the program.
There would have been no space telescope until the uncertain launch of the next one. And, although new-technology land-based telescopes may someday achieve the same quality as a space telescope, they aren’t there yet. So there would have been nothing to fill the void.
I’m glad the Hubble is being repaired — and broadcasting the repair makes great TV.
And the only way we’ll get that is if we build hundreds of vehicles, not a scant handful. If you don’t mass produce it, it’s going to become outdated very quickly. And the number of missions you can run is extremely limited.
What? What? The claim that land based telescopes are matching or surpassing Hubble is based on the success of sophisticated techniques for overcoming atmospheric distortion.
I think the argument remains largely economic. You can support some number N of these ground instruments for the cost of 1 Hubble, and the scientific return is judged by some measure to be equivalent.
Still, the Hubble enjoys unique advantages, and it would be a great mistake not to exploit them to the fullest, IMHO. It’s just about the best thing we’ve got going in LEO, and if it’s too dangerous to service it, well, let’s just go back to bed.
I've always been a great supporter of the Hubble; actually got to see the mirror and touch the launch package.. Man, am I really that old now? Anyway, the conceptional problem is thinking that we only need six or so launch vehicles, even if they are reusable. We don't need that, we need thirty or sixty. The cost per vehicle, and their value, means the loss of one impacts missions for years to come. And we are talking rocket science here - bad things will happen. You have a controlled explosion of highly combustible materials that flings something into space. Even if you have a ninety-nine percent success rate, you've got a critical failure to contend with every eight years or so.
We don't need a new Hubble, we need three of them, designed to have every component replaced at whim. And making three of them with less shielding, less worry on the ground about parts failure, would in the long run mean far better science and far cheaper costs.
common sense, as you state it, is all too uncommon.
[It cant be done...it cant be done...to risky...too much money...it cant be done.]
...and then Rudy rode in to the rescue.
Excellent and Thanks!
Save the Hubble BumP!
The only problem I have with the James Webb telescope which is in the works is, I really hate “MacArthur Park”. /rimshot
