Astronauts, Robots to Save Hubble 213

Posted by michael from the tag-team dept.
BungoMan85 writes "Astronauts who serviced the Hubble Space Telescope, among others, feel that NASA's administrator Sean O'Keefe shouldn't be too quick to abandon the now 14 year old space telescope because of safety concerns arising from the Columbia disaster." And an anonymous reader writes "At the insistance of congress, NASA is looking for a way to save the Hubble. "It's the most unpopular decision I could have made," Sean O'Keefe said of his decision to cancel the shuttle mission planned to fix Hubble. He has authorized his engineers to pursue the possiblity of a robotic rescue mission. This could be a great opportunity for private industry contractors."

      Sure there are astronauts that would do this, and test pilots and jet jocks galore. Fortunately it's not their decision to make. An older and wiser head has looked at the risk (much larger then previously thought) consider the consequences if it went to hell (loss of yet another shuttle, loss of five to seven MORE astronauts, NASA being gutted after Congress and the public scream in outrage about "Why did you ever do such a thing after the Columbia boards recommendations???") and all the various other fall out, and decided the game ain't worth the candle. Look nobody wants to see Hubble fail, and NASA isn't talking about splashing it down tomorrow. It's got a few good years left. The problem is that the upgrades would only keep it going for five to seven years longer then otherwise and it simply isn't worth risking the human lives and cost to the program. The stars and galaxies and all will be there in a dozen years, why not use this sudden outpouring of concern for this myopic bird, to build a better scope and launch it? Why so much sudden attachment to a scope that everybody and I mean EVERYBODY jumped all over as a bat-blind hair-brained piece of junk when it was launched? I mean it's nice to be loved and all, but let's get some perspective. The truth is that it would be much more fun to design and build a better scope and do even better research. I'm not talking James T. Webb here, I mean a new visible light to UV scope, with better resolution and more thought into the science we would like to do, now that we know what kind of science we can do. And build one that doesn't require the Shuttle, because Shuttle is gone once ISS is finished.
      We have three shuttles left out of five (which means that we can only do 3/5 of the mission flights we had planned to do every year), we have much more hardware for ISS, which is even more expensive then the repair and replacement parts for Hubble, sitting around in Florida. We have numerous international treaty commitments to our partners, many of whom are supposed to be paid with flight time on ISS for their contributions, which have to be honored. And after the Columbia boards recommendations any NASA administrator that decided to still go ahead with shuttle mission, at those orbital parameters, would be putting himself out on a very long limb, far, far above the ground, and inviting old man Murphy to come along with a saw. Commonsense says "Sorry, but this is a bridge to far." Understand that the game is changed. We got burned once, thought we had learned our mistakes, fixed the obvious problems we saw and went back to flying it. Now we've been burned again, and a LOT of the reasons sound hauntingly familiar. Well fool me once, shame on you, fool me twice, shame on me. NASA manned flight has suddenly gotten VERY, VERY RISK ADVERSE. The idea that "Oh well we fixed these problems, now it's all better" suddenly sounds like a lot of Pollyannaish nonsense. NASA will do what it must with the shuttles, but it will hold its collective breath every time it launches one from now on. Safety is no longer our watchword; it's the ONLY damn thing I hear about nowadays. Congress might vote to override O'Keefe, if they do then on their heads be it. If they do then they better get ready to collectively resign if anything goes wrong, and they better have the letters to the families written in advance, just in case, cause that's what Shawn O'Keefe would have to do if he had made the decision and it went pants, as the Brits say. Those who are so quick to judge aren't the people that will have to explain it to the president, congress, the families, and the general public, until they are, they can darn well be a lot less dogmatic about this. And that's my view for whatever it's worth.

      • An older and wiser head has looked at the risk (much larger then previously thought)

        No, that's not right. The risk of failure after the wiser heads of CAIB investigated the Shuttle fleet was the same as the assessed risk before the accident. Nothing has changed about our knowledge of the risks involved in a shuttle mission before and after the accident. Only the willingness to face the risks has changed, and that abruptly.

      • Astronauts have been dying in accidents since the 60s. One shuttle blew up in 1986, before Hubble was put up. You think the mission to put Hubble in orbit was risk-free? The repair missions? Of course not. And it was known then that they were risky. Nothing has changed except the identification of a new flaw in a field where errors can mean instant death.

      According to current plans, there will be several years between the Hubble being decommissioned and a new space telescope taking its place, and that's assuming everything goes according to Bush's plan. There's no alternate instrument that can do what the Hubble does during that time, so a large subsection of astronomy as a whole would be crippled.

It's like throwing away an old Civic just because you might buy a BMW -- no reason you can't keep both cars in your garage, and there are just some things that a Civic makes sense for.

          This is why your analogy is bad. The point is that it is not a small investment. NASA would have to violate the recommendations of the CAIB report for safety, actually create known unsafe conditions, and risk the entire shuttle (and ISS) program just to keep the Hubble alive. This is most definitely not a small investment.

            There is a matter regarding developing a robot to service the Hubble. Part of the party line on the manned space program is the limitation of robots. While the Hubble optics error was a dark moment for NASA, the Hubble repair mission with a lot of complex, long space walks was a "jewel in the crown" of the manned space program, and if they can get a robot to do the repair, it would kind of puncture that concept.

        Also, the Hubble's replacement, the James Webb Space Telescope [nasa.gov] isn't quite a replacement for Hubble. It won't be launched until 2012, does not see in quite the same region of the spectrum and will be sitting at L2, well out of the range for servicing.

        One of the things that has made the Hubble truely unique is the ability to be serviced. Each service mission has improved the telescope's capabilities tremendously. The Webb, for all its grandure, once it is up, it is up. No serviceing mission to bolt on a new camera, no trips to fix the optics. What we get day 1 is what we get day 100 and day 1000.

        In the meantime, we will have at least six years without an optical range space telescope. That's six years of supernovae, six years of gamma ray bursts, six years of star formation, six years of light echos and six years of deep field astronomy that simply WILL NOT HAPPEN.

      No, we should not just let it go, especially not when we've already spent $200 million on the instruments that are supposed to be installed in the next mission. HST is quite possibly the greatest scientific instrument anyone's ever built. You don't just throw it away unless you really have to.

      Or is this really about hating Bush's attempt to bring a man to Mars, and undermining it anyway possible just because he's Bush?

      Look, no one believes that Bush is serious about a manned mission to Mars, least of all the man himself. His proposed reshuffling of the NASA budget to pay for it is sub-laughable.

      I can't see why people are suddenly spendthrift when a Republican president wants to do something, but we can spend billions on welfare and hike taxes up to strangulating levels without anyone complaining under a Democrat.

      Please, get serious. What are these "strangulating" tax levels you are talking about, and under whose administration did they occur? If you look at this page [taxpolicycenter.org], you'll see that tax rates have not appreciably changed since 1980. In fact, that same chart will show you that most people's taxes were actually lower in 2000, when the Man You Love To Hate left office, compared to 1992, when he took office.

      Maybe people seem spendthrift because the Bush administration is mangling our budget with explosive spending programs coupled with irresponsible tax breaks for the rich. This results in (suprise, suprise) huge deficits which our children's children will be paying for. This isn't "just party politics"; fiscal conservatives are crying foul about Bush Economics as well.

        I don't want to sound rude, but why must we take this to politics... this is a civilian space agency, and we should treat it as such (and not some government pet project as most administrations have used it: Kennedy for the space race, Bush for gaining a stab of popularity and spicing up discussions everywhere).

        Politics aside, we've made an investment. 15 years of a working Hubble telescope. That time runs out next year and we're still a solid 6 years behind on a solid replacement (which, is still questionable, since everything I read tells me it is planned to be like the Spitzer telescope and take pictures in Infrared). We also made the investment on 200 Million USD on upgrades to Hubble. 200 Million dollars is a lot of money to put towards something that can probably never be used with any other piece of equipment except Hubble, and not put it to use.

        And I don't buy this Bullshit O'Queef is selling us about the worries of the shuttles. They're operable as is already, and what happened on Columbia was a freak accident that nobody thought to try to explain until it was too late. Maybe the money that could be going to building these "robots" could instead be used to build a wing crawler, to crawl out and service the underbelly of the Shuttle in case of such a disaster.

          This is actually a logical falacy. I learned about this in a decision theory class I was in for a while at Cornell University. Previous investments should not directly affect economic decisions like this, only the current situation. That is, just because we spent lots of $$$ to make Plan A work does not mean we should continue with Plan A even if Plan B does the same thing for less additional money.

          Imagine that you buy a truck for $10000. You then end up putting several more thousand dollars into it for repairs (like we did with the hubble). You even got a nice big turbocharger to put on it for when it's fixed next... however you get a bill saying it'll cost $4000 to fix the truck. And it's getting old. And lets say truck technology has advanced so much that for $4000 you can get a nice brand new truck that's even better. Rational decision-making dictates you would purchase the new truck - despite how much money you put into it in the past.

          I'm not suggesting that we currently have an alternative to Hubble that does the same thing for a better price, however previous investments SHOULD NOT dictate our policies, only the current scientific/economic facts.

            It's more like you have that $4000 bill to fix the truck, and while you can buy a new truck for $4000, you can't take delivery for a few years.

So, you can either pay the guy $50 to install the part and drive your awesome tricked-out truck for 4 years, or you can refuse, and walk for 4 years.

Most people do not know anything about the Hubble other than it's a Good Thing. What a shame it would be to destroy it! So, by announcing plans to toss the Hubble in the garbage, NASA effectively primed the public to be willing to spend more dollars on space-related stuff.

      but shouldn't we just let it go ?

      If you are asking that question honestly, then its obvious to the scientists among us that you have little or no appreciation for the information that this great instrument has brought us, and will continue to bring us for quite some time if its maintained. That instrument has single-handedly multiplied our knowledge of the universe we live in by a factor of at least 100, and refined some of our +- 50% guesses down to +- 5%, simply by being beyond the reach of the limitations in optical bandwidth that our planets atmosphere places on all the ground based scopes. Its done things that all the active optical stuff we've put on mountains so high that they are run by remote control still couldn't do.

      The "next generation" telescope everyone is drooling over is designed to do an entirely different job, and is in no way capable of overlapping what the Hubble can do in the visible and near infrared spectrum. And it will be like the Hubble in terms of delays, so I don't see it going up in my remaining lifetime since I'm 69 now. Yes, it will also do good science when it goes up, but it cannot do what the Hubble is doing in the wavelength range between visible light and near infrared, say an octave either way from yellow/green as our eyes see color. IIRC its designed to work in the far infrared and into the microwave, where its resolution at best will be 1/10th that of the Hubble. But it will see thru dust clouds the Hubble can't too. We won't know what the region around Sag A really looks like until it does go up, Sag A IIRC, is supposedly very near if not the black hole this galaxy spins around.

      As far as a manned mission to mars is concerned, thats where I feel that the remoteness and generally inhospitable conditions which combine to make it a one way trip preclude using anything but prisoners already sentenced to death for such a mission.

      Considering the intelligence level of someone dumb enough to have gotten themselves in such a predicament in the first place, I'm not too sure that we would gain much in the way of scientific knowledge by following that distastefull to many path.

      I look at it as political posturing, an attempt at giving NASA a "reason de terre", as opposed to fireing that whole bunch and starting all over again. Thats something we should have done when the first one blew up. This new shuttle loss just confirms that the old boy network that covers their ass MOST of the time by sheer luck alone, is still in place.

      Human nature being what it is, I'm not even 75% sure that a total housecleaning would even fix it now. But I think a wholesale fireing, and maybe even a highly public manslaughter prosecution of the decision maker who passed on the loose foam problem might have a sobering effect on all the pie in the sky folks NASA seems to have collected down thru the decades. Nobody learned anything about common sense safety after the fire in Houston (and the test admin who ordered that test should have been prosecuted for murder) nor from Apollo 13 when there was a clear indication of a problem with the tank heaters thermostat before they launched, the only thing actually fixed was the booster seals after the late 80's blowup, and this time the loose foam was known, and had been known for at least the last 20 launches, possibly for much more time than that. But nobody has stepped forward to actually admit that doing the launch was a bad idea, "after all, it hasn't been a problem before now, why should this time be any different?"

      IMO that attitude will not change until someone actually does some hard time. The agency needs the same accountability as you and I would get in a prosecution for no less than manslaughter in 3 of these 4 "accidents".

      For (probably) 3 times the cost of the repair mission, a telescope of (probably) 100 times the quality of hubble could be deployed.

      Do you have *any* basis for a claim like this, other than "your gut feeling"?

      14 years is a long time, around 10 iterations of the "performance doubling every 12-18 months" if you're talking about computer technology. But optical technology has been stable for quite some time. Or, do also claim to have binoculars 512x-1024x better than your dad's?

      Remember, Hubble is not a computer - it's a telescope. And, since image processing is done on the ground, advances in computer technology are likely largely irrelevant to the Hubble.
      • Only thing I can think that might be different between the time when Hubble was launched and now is the technology used in the collection of the image itself. We can make much more sensitive CCD's (or CMOS's, which NASA would probably prefer...) for cheaper now, allowing for a much higher resolution picture to be taken.. BUT: since we're already building another telescope, there's no reason at all to throw money at upgrading this piece of hardware, since it would undoubtedly require quite invasive work.

Other posters have pointed out that the servicing mission is to install more modern technology on the telescope -- EXACTLY WHAT YOU WANT! And for image quality (spatial resolution, which is what Hubble does best) 100 times that of Hubble, you'd need a 250 meter telescope in space, which we probably can't do this CENTURY unless we spent the entire GDP. We have a better telescope planned right now (the James Webb Telescope budgeted at yes, about 3 times the repair mission cost), for probably 2012, which is better, but not 100 times better, and won't work in the ultraviolet AT ALL. I'm an astronomer who uses Hubble, and I bust my ass working on proposals to use the thing because I have science to do that I can only do with Hubble, not for sentimental reasons.

      I'm really hoping the decision to not save Hubble was really a brilliant diversionary tatic to get more money for NASA. If NASA had originally committed to servicing Hubble, then they probably would have had to cut somewhere else, where probably very few people would have cared. But if they decide to scrap it, and everyone (including Congress, with all the money) rallies to save it, then NASA gets to keep the other projects and Hubble.

      The other possibility is that they just decided to dump it and didn't think people would react like this. I guess it depends on whether O'Keefe is really smart or really stupid.

    I honestly don't understand this American concern for human life in such insular situations. Instead of asking for volunteers to rescue the Hubble, NASA has to spend some inordinate amount of money to reduce the risk factor by an impressive tally of 0.01%. There is no shortage of people who would be willing to risk their lives for the advancement of scientific discovery and human knowledge as a whole, yet apparently their passion to actually do something is nothing but vestigial barbaric brovado. Deaths that transpire under mundane circumstances (car accidents, drug-addiction deaths, gang shootings) are shrugged off as just a "fact of life," whereas sacrifices made for the selfless pursuit of nobility are deemed unnecessary and wasteful. Its absurd. There are people in the world who would end their lives forty years before their time in return for the chance to look out into the inky void and see a lone blue-green planet from a vantage point that few others have even dreamed of scaling, yet they are held back because of the terrible national tragedy that might occur if a nameless, faceless human were to die contently in one location rather than despairingly in another.

      No, it's not really that possible or easy. It would take a lot of energy to change orbits that radically. Things don't go around the Earth at the same height (and I'm not talking a few hundred feet, either) the same direction (angle), and for that matter, the same speed. Hell, some orbits are highly eliptical and some are circular. To match an orbit with an object you pretty much have to launch into that orbit. Slight corrections can be made in-flight, like moving up close to it, but this also pushes you to a higher altitude due to your increased speed. Likewise, if you slow down, you tend to fall as well. The Hubble is quite a ways out there IIRC, now imagine the ISS being on the other side of the planet when the crew needs to get there, and you quickly see how this becomes pretty impossible.
