NASA Announces De-Orbit Mission For Hubble

maglor_83 writes "NASA has announced the end for Hubble. It plans on performing a "robotic de-orbit mission", and apparently its not due to the monetary costs associated with fixing it, but rather the risks involved. NASA's new goals are now manned missions to the moon, as a platform for Mars."

Scientific payoff

[BWJones]

OK....... I cannot see what the near term scientific benefit is of sending folks to Mars. Hubble? Hell yeah. The moon? Absolutely, .......but Mars? Look, Hubble has generated more scientific data per dollar than just about any other NASA program as well as helped out more than one project in the defense department and fed data to scientists and scientific organizations world wide. A return to the moon, could certainly function as a refueling point for unmanned missions to other planetary and stellar objects, as well as functioning as a potential resource for mining (with a space elevator which would facilitate this), and a remote optical and radio telescope on the moon could be an extraordinary scientific resource, but I am not sure the payoff of killing Hubble in favor of manned missions to Mars are currently worth it. I would much rather see more investment in sophisticated ground and space based "scopes".

Given current technology, I see a manned mission to mars as a financial boondogle.

Part of the scientific process that often goes overlooked is that when you are trying to solve one problem, you often solve other problems that lie along the way, and sometimes you make accidental discoveries that lead to developments that you never thought might be related. Thus, science for science's sake is generally a far more useful [and maybe even noble] pursuit than most of the other things we do.

Consequently, you really have no idea what kind of bang for the buck will be produced by, comparatively, setting up shop on the moon, and setting up shop on Mars.

This is why we go to the moon first. Of course we can't do it with current technology, and if we keep sending up robots, without the incentive to develop better and faster propulsion, etc., that's all we'll ever have - current technology.

Get people up to Mars successfully, and we won't waste any more missions because of stupid "convert to metric" errors and the like that have doomed most of the robotic Mars missions to date.

No more sending up a robot, finding a tantalizing piece of data, and then waiting 5+ years to get the next round of questions answered. This is tedious and silly! Put PEOPLE on the ground with the right equipment for a year, and your precious "science" will start to ROLL in instead of TRICKLING in like it does now!

(sheesh!)

Step 1: Moon base.
Step 2: Build the next generation of spacecraft on the moon
Step 3: Launch Mars mission from the moon, where the gravity well is shallower.

Re:Scientific payoff

[NatteringNabob]

It has nothing to do with Scientific payoff and everything to do with Electoral votes. If you wanted to pick up a key southern state, say Florida, and you knew that their key reason for existence was about to disappear, you might want to invent an extremely expensive, open ended, project to keep thousands of potential voters employed. Let's face it, the Mars Rovers and Cassini probe have demonstrated pretty conclusively that space exploration is a job for the bots. They are cheaper, more tolerant of extreme conditions, and if they die, nobody cares much. The 'man on mars' program has nothing to do with science and everything to do with politics.

This is trotted out every time that the space program needs justifying and guess what, its bogus. Non stick frying pans were being developed during the Napoleonic wars when the English embargo prevented the French getting their hands on enough cooking grease. Hence LeCreuset.

It gets even wobblier when you get to the old CERN home of the Web stuff. The folk who go on about that don't mention that CERN never assigned any staff to the Web project directly other than Tim during the time Tim was at CERN. There were three students who worked with Tim and another four people from another group who did the Web because they beleived in it. When it came to setting up the Web consortium the CERN director sent to bat for the Web project EU grant wise told the committee that the priority at CERN was physics and the Web was not considered important.

Even when you get to communications satelites the story is somewhat murky. Most satelites are being launched by the French or the Chinese and NASA has done its best to make use of those facilities as hard as possible.

If you want to research networking then give money to networking, if you want to research biochemistry give the money to biochemists. Do not give the money to a bunch of astrophyscists in the hope that they will solve your networking, fusion, and life sciences problems in their spare time. It does not work that way. The only way you can see a return on 'spinoff' research is if you have programs in place to identify and invest in them. NASA ditched all that years ago and there is zero chance of picking any of it up in the current budget cut environment.

There is no way that shutting down Hubble and spending the money on the space station is going to get even 1% of the science that Hubble has delivered already. The basic problem here is that NASA sees its mission as manned space exploration and that has very little to do with science.

There is one solution to the problem that has not been discussed much. There were two mirrors made, the bent one that is up there today and the reserve that was made (corectly) by Kodak for testing purposes. The Kodak mirror must still be in storage somewhere, there are duplicates of pretty much all the equipment. the parts could probably be bolted together to make a duplicate for $50 million or even less. The French, Russians and Chinese would probably put it into orbit for $50 million at commercial rates and given the cargo it could probably be done at no cost in return for telescope time.

The cost of Hubble is almost all in the design. Making a duplicate should be much, much cheaper.

Re:Scientific payoff

[quanticle]

Well you never know...

Given Creationism's recent gains, and the growing power of the Religious Right in the administration, one might believe that yes, indeed, Hubble is being brought down to set back science.

Re:Scientific payoff

[jelle]

If anything is capable of looking beyond the nose into the depths of the Universe, it is Hubble.

Now, truth of the matter is that they are going to do the 20+ shuttle flights to finish the space station, whose science results have pretty much been limited to 'hey some moss grows in circles in space', and explaining to highschool kids how astronauts live out there. doing valuable circular-growing moss research and all.

But the risk and cost of single flight to keep Hubble operative is too high, and the 20+ for the space station are worth the cost and risk?

Right. I'm not convinced.

This is not about Mars, or the Moon. Mars and the Moon are just decoys. They are only mentioned to make people drool like you are doing.

Most likely, NASA will never get sufficient funding (and balls) to actually go do it. If it's too risky and too expensive to go fix something in orbit, that has been specifically designed to be fixed, then please tell me, how can flying people to the moon and another planet be affordable and safe?

Double standards, that's the only way.

You sort of prove the point... You never know what you will develop until you have a strong need. BTW Teflon has nothing to do with the space program. It was developed for the Atomic bomb project. It was uses for seals exposed to Florine.

"Even when you get to communications satellites the story is somewhat murky. Most satellites are being launched by the French or the Chinese and NASA has done its best to make use of those facilities as hard as possible. "
THis is just nuts. Of couse sommunications satellites where developed by Nasa and AT&T.

When you push the state of the art you never know what you will develop. IC based computers where developed for the Apollo program. Why never before? because no needed computer that small before. I mean why would you need a computer smaller than a desk or even a room?
Remote heart monitoring systems. Why would you need to check someones heartbeat remotely.
Yes the space station is a waste. Not because it is a bad idea but because it was cut and cut and is now just a shell of what it was going to be. Much like the Shuttle.

Hah! see my other post, Teflon was invented in 1938, before the Manhattan project started.

The USSR did not develop ICs and still put rockets into space. In fact the ICs did not become important in space until after the Appolo program. They were pretty finiky until the 1970s.

Kilby was funded by Texas Instruments, Noyce by Fairchild. Both companies were working for the Pentagon, not NASA. The first applications for the ICs were in the US Airforce and the minuteman missile (1962). There is a big difference between using an IC in a missile where it has to work for no more than a few minutes and using one in a satelite or such.

There are certainly links between research fields but space is certainly not unique in having a spinoff effect and you do not get spinoffs without also doing basic research in the area in question. The World Wide Web put together ideas from twenty years of formal comp sci research with a different perspective to reach the breakthrough.

I don't see any reason why we should expect that diverting funds from worthwhile science like Hubble to worthless science like the space station is going to result in a net gain through the spinoff effect. Space has been enormously well funded for fifty years. Sending people to the moon does not create any seriously interesting new challenges.

NASA has it wrong

[Garbonzo Pitts]

NASA has consistently pushed the idea that manned space flight gets the public's attention. But the facts indicate otherwise. Photos from the Hubble and interplanetary probes appear on the front pages of newspapers and have a very high "ooh-ahh" factor. In contrast, the public doesn't seem to care at all about astronauts in the space station. Why would they care about people going back to the moon? They've seen those pictures already.

and one giant leap...

[Engineer Andy]

backwards for mankind.

It's a pity to lose such an excellent scientific tool without a replacement either in train or already deployed

Re:and one giant leap...

[Pxtl]

Except that Webb is not a visible-light telescope. So no, a replacement for Hubble is not in the works.

It's not the end.

[Hrodvitnir]

Honestly, all this uproar over downing Hubble is a bit dramatic. It's not the end of space research. We'll keep sending up satellites and they'll keep getting better. There's just going to be a hole fore a few years where we won't get the type of data that hubble was able to provide.

We will put up a satellite to replace the Hubble. Space isn't going anywhere.

If they say it's not about money...

[SteeldrivingJon]

It's about money.

The budget Bush just submitted cuts the Hubble.

It's official...

[rasafras]

NASA is dead. When you claim risk and safety as a high priority for exploration and scientific conquest, you know you aren't going to get anywhere. Lewis and Clark didn't wait for the invention of the SUV before going cross-country, they just went ahead and did it.
I'm not saying that exploration should cut corners and put people in unnecessary danger, but there are astronauts willing to risk going up to do things like this. Face it, shooting somebody into the sky on a giant bomb is inherently unsafe, and that's something you've just got to accept. I understand that another accident for NASA would cut approval and potentially cost them far more money, and I'm saying that that's the problem. Trying to be unnecessarily safe is going to cost them far too much money, and that's money that they most likely don't have and won't have to spend.
(I was referring to the Mars mission as well)

We're going to the Moon!

[TheOriginalRevdoc]

Yippee!

It's gonna be just the ISS. They'll spend billions designing amazing machines, the budget will be cut 50%, they'll redesign, the budget will be cut another 50%, they'll redesign again, then they'll put up a half-arsed end result that barely meets its mission requirements.

Then the astronauts will hang out on the moon, kicking rocks and wondering what the hell they're doing there. They'll do a trial collection of Helium 3, but there won't be any point, because there's no use for Helium 3, even if we could get it back to Earth.

Eventually, the engineers will admit publicly that getting to the moon doesn't contribute to getting to Mars in any meaningful way, but boy oh boy, the contractors sure made a shitload of cash off the project, didn't they?

And isn't that what American politics is all about?

Baby with the bathwater?

[fygment]

We have Hubble which:

1) captured the public imagination. How many posters have you seen bearing pictures from SOHO, Chandra, or any IR camera? How many kids turned on to astronomy after seeing a Keck picture?

2) is known to a huge swath of the public. How many know of SOHO?

3) has a very positive track record. How much bad publicity has Hubble generated for NASA? It was recovered heroically from its intial flaws and has performed stunningly ever since.

In its place:

1) a cosmologists dream machine (read: pictures in the IR that show little blobs of the early universe). Not for public consumption.

2) no inspiring name has been fielded though there is time to fix that. NGST? But Hubble was the first so NGST faces an uphill battle.

3) a telescope many people don't want so money can be diverted to a mission fraught with more danger and potential bad publicity than a space walk.

So getting the axe is: a popular, inspiring, positive public face for NASA. In its place, an item on the drawing boards to free up cash for a truly extreme mission. Begging the question, can NASA make any good decisions?

Re:There is no deorbit module

[Odo]

> There is no robot to send up to bring it down. They want to be able to command it down [...] BTW my father worked on pointing and control on Hubble. I'm no expert, but I've spent many nights asking him a lot of questions about Hubble.

Oh man, you seriously need to have another chat with your dad. Hubble can point itself in any direction thanks to its gyros. But it doesn't have any engines. It couldn't deorbit itself if it wanted to. They have full control over where Hubble looks, but not where it goes. To deorbit Hubble you need a robotic deorbit module (aka a rocket).

Re:Moon as a platform for Mars?

[mboverload]

You seem to have little concept of the situation.

A rocket/shuttle/anything uses up pretty much ALL of its fuel just to get off the ground. If we could land on the moon, not only could we go faster (full fuel + no air + moon swinging around) it would be safer because the mission would have spare fuel to use on the way to Mars. Plus you have enough fuel to get back since you would be using a capapult+rockets to get on your way.

Re:The billion taco question is...

[The Good Reverend]

The fact that you're still talking about it, and know it was Taco Bell, 4 years later is a pretty good sign that it's absolutely not a "brain dead marketing scheme". It was a no-lose situation for the company. Consider:

Situation 1: Target is missed. It still captures the public's imagination, gets people talking, makes people like you bring up the event years later. To marketing departments, this kind of exposure is exactly what they love.

Situation 2: Target is hit. They have to give away upwards of 300,000,000 tacos. Except, no where near everyone would go, and those that do would likely order a drink, burrito, or other side dish. Even if none of them did, it's still eyeballs and foot traffic, not to mention amazing amounts of publicity. That, and the promotion was insured.

That silly little $40,000 blow-up target is one of the best things that company every did for itself, second only to a talking dog.

Why not boost Hubble to higher orbit?

[wildsurf]

As long as they're sending a booster to Hubble, why not just boost it into a higher orbit, where it can stay parked for another several years, at which time we might have better means to do something useful with it?

Perhaps even bring it down safely for museum display?

It seems like a waste to send the booster all the way up there just to destroy the telescope.

What we are capable of

[SuperKendall]

Like what? And what can we not do remotely? Why send astronauts there is what I am asking.

What can we not do remotely?

First of all, consider that everything both rovers, combined, have done to date could have been done easily in a day by one human scientist with a buggy. Possibly even on foot.

Now consider what the rovers have not been able to do, such as going on steep slopes or overly sandy surfaces for fear of getting stuck - things a human could have just walked right over to.

Now consider the things that are just unthinkable for rovers to explore, like really complex canyon-laced terrain. You just can't send rovers there at all.

What is to be gained? A deeper understanding of geology and the forces that shape planets - perhaps offering new insights into our own planet. Possibly of course other lifeforms if they probe deep enough. And all the variety of technology that makes working on Mars practical, like improved propulsion systems, life support systems, etc.

But basically it would be a fantastic boost for the human spirit. Look at how riveted so many people have been to Rover progress, and the Titan mission. Lots of people know about these things and it excites them. It could help to really raise a new generation of engineering minded youth, whereas right now I'd warrant a lot of good potential scientists end up as MBA's or lawyers right now. After all, what is compelling or cool abotu going into science?

If you want a planet full of lawyers, by all means lets shut down manned space flight and just sue each other for IP infringements every time we make a sandwich. But frankly I hope for a more inspired future.

I know it may sound crazy to you, but I would quite happily take a trip to Mars knowing I would only live a day and there was no hope of return. And I think there are a lot of other people like that. Let people with the will to explore go forth and inspire others in turn.

Re:This makes utterly no sense.

[cgenman]

Remember, the apollo missions were taking 10% of GDP for the 10 years or so it was active. I doubt this mission will get that kind of funding.

Plus you're talking about a space agency that goes trolling on eBay for parts to older systems. If they're going to do a moon mission, they're going to have to modernize. Which means re-making a lot of what they had done with a lot of different technology providers.
