A Way to Save Hubble? 65
An anonymous reader writes "The maintenance flight to give the Hubble Space Telescope a few more years has been cancelled, even though everyone agrees that HST does good work. But this article offers a way to save the space telescope, and to give those who think the space program should be privatized a way to prove they can do it."

Rather than hope that some small or large corporation agrees that a profit can be made off of Hubble research, the government should take a stand and finance basic science for its own sake, instead of ruminating about a massive aerospace industry welfare program under the cover of an exciting bunch of missions to the Moon and Mars.
Of course, I'm not so naive as to think that the government actually would change their priorities on this. After all, with all the tax cuts to the rich and a couple of expensive wars to fight, hard choices have to be made, right?
And we still need our Federal mohair subsidy program, so it's time for Hubble to go!

What exactly would Hubble need to keep working? Boosting to a higher orbit, because its current orbit is decaying? And Hubble's gyroscopes are wearing out, and will need replacing.
So, how expensive would it be to build a robot that gently grabbed ahold of Hubble, gently boosted it to a higher orbit?
Would it be possible for a robot like this to use its own gyroscopes to keep Hubble stable?
Yes, I know there are also new lense modules, and similar, but they would require an astronaut to install them. Well, maybe they can wait until the safer replacement for Hubble is ready.
Could the robot have enough fuel to move Hubble to orbit next to the ISS?
There is supposed to be a replacement for Hubble, that may be ready in ten years or so. But it might not be ready. And it might not work. Hubble works. Maybe they should keep Hubble until they know the replacement works...

Before I wrote this, I took a look at your Vitae [bc.edu] and confirmed what I suspected: You have always been payed by taxpayers! I found no private sector experience at all!

The contention that saving the Hubble is "Basic Science" is ludicrous: it is an incredibly expensive project that is nearing the end of its expected duration anyway. I'm certain there is more we can learn from Hubble, but we are talking about billions of dollars to save it for a few years!
By the way, Professor, just why are you so bitter about this particular item? Have you ever actually used Hubble data during your search for better School Systems [bc.edu]? Or are you just like the rest of us: mesmerized and inspired by the amazing and beautiful pictures [stsci.edu].
Professor, the case for saving the Hubble may be strong. I'm not qualified to make that call. However, our elected officials have decided that the massive cost involved in saving it is not something that our tax dollars will be used for. A part of me is delighted! It's the first time in months I've seen them say no to anything! If you have evidence that they're wrong: let's see it.
Personally, I hope that the approach suggested in the article (you did read it, right?) is followed: let those who find this project crucial and needed say so with their pocketbooks. If they do, I (like most /.'ers) will delight in the images and wish them the best.
However, I hope that you remember that there are those of us in the audience (even here at /.) whose blood boils when they read a comment such as yours! We aren't protected in our ivory towers: our jobs will go overseas if we don't bust our asses. We aren't rich, but those tax cuts saved many of us our jobs! They let others save more and helped to put their kids through your classes.

Aerospace welfare is keeping the shuttle and space station fantasy of space exploration alive. NASA employed a small army just to keep the shuttles in working order and ISS is just too pathetic to contemplate. Manned missions to planetary bodies is the correct direction for space exploration. That's where the science can be done. All the astronomy that Hubble did could be dwarfed by a lunar telescope array.
NASA is finaly breaking out of 30 years of aerospace welfare. The new space push [moontomars.org] is finaly something done right. Let's just hope they stick to it and do it correctly.

At least we should boost Hubble to higher orbit, so when NASA gets additional funding, it can try again to bring it down. Putting it in a museum somewhere would really be a inspiration to many children to go into science.
C'mon, that's crazy. It's like suggesting we should've brought Mir down in pieces in a shuttle or something. Hubble's an old space telescope, and we've thrown many old space telescopes away.
You could build a replica for a fraction of the cost that it would take to bring it down. That'd be good enough for inspirational purposes.
The only reason that people are averse to doing it now is because somehow "Hubble" got a lot of public support, but it really doesn't deserve it. It's just an old telescope. Sure, it does good science - but so does any instrument if there are people operating it. The point is "is it worth spending money on something when that money could be better spent on a better replacement?" and the answer to that is "no".
NASA never should have let Hubble get into the public's eye this much. The pretty pictures can come from pretty much any other telescope (Spitzer put out a few nice ones over the weekend) - there's no reason to keep fawning over Hubble.

I think the important part of the thing is in the next to last paragraph where he says "a permanent presence on the moon will provide a far better platform for a space telescope, and it is likely a telescope will be put there." And he implies it is only ten years off - though putting a permanent presence on the moon is probably 10 years off at best and expanding that to a good astronomical telescope would probably stretch another 10 or 20 years. If it even goes through and is not abandoned after the election. (Any bets on Republican support for such an endeavor if a Democratic president is supporting it?)

As the slashdot saying goes, "BZZZZZT!"

Second, if no shuttle goes to Hubble, they have to build a special remote operated tug to match orbits with Hubble to bring it down under control, rather than let it wobble around and possible land big chunks on people. But a repair mission could install a much simpler de-orbit rocket as part of its mission, and I bet the costs would be a lot less, compared to designing a one shot remote operated booster.
