No Formal Risk Analysis of Hubble Rescue by NASA 186

Somegeek writes " SpaceDaily.com is running a story that NASA never performed a formal risk analysis of a shuttle mission to rescue the Hubble Space Telescope before they decided to cancel the mission on grounds of risk. The story quotes Fred Gregory, the current acting NASA administrator, as stating that previous NASA administrator Sean O'Keefe made the decision "based on what he perceived was the risk". This perceived risk is in performing a manned shuttle mission that is out of range of using the International Space Station as an emergency refuge. The Hubble's current batteries and gyroscopes will probably fail in a few years, leaving the dead telescope to crash back to earth around year 2020."

        I don't think it's fair to put all this on him. A lot of this comes directly from the CAIB report [www.caib.us]. Recommendation R6.4-1 states:
        "For missions to the International Space Station, develop a practicable capability to inspect and effect emergency repairs to the widest possible range of damage to the Thermal Protection System, including both tile and Reinforced Carbon-Carbon, taking advantage of the additional capabilities available when near to or docked at the International Space Station.

        For non-Station missions, develop a comprehensive autonomous (independent of Station) inspection and repair capability to cover the widest possible range of damage scenarios."

        Now they've just spent 2 years and hundreds of millions just developing the capabilities for inspecting and repairing based on the ISS option. The autonomous option is many years and probably billions of dollars away, and they only have a few years to repair Hubble before it goes down. Add to this that they're not supposed to be schedule-driven anymore by Recommendation R6.2-1:

        "Adopt and maintain a Shuttle flight schedule that is consistent with available resources. Although schedule deadlines are an important management tool, those deadlines must be regularly evaluated to ensure that any additional risk incurred to meet the schedule is recognized, understood, and acceptable."

        So NASA's in a tight spot here. Don't be schedule driven yet develop all of these capabilities that take years and huge budgets to develop but do it in time to save Hubble. And then they're retiring the shuttle fleet a few years later anyway so all of this effort and cost for the "non-ISS" flights is really just for Hubble. I'm not saying O'Keefe made the right decision, but I hardly think he deserves the trashing he's been getting on this decision, which isn't even final yet. It seems like a very sound decision given the circumstances, but we'll see how the political will finally responds.

If the goal of continuing Hubble's mission (which is a very complex and dynamic issue to define in the first place) does not outweight the risks, then that's fine. But have the data to back it up.

      I don't know if this is what you are trying to say-- I can't quite tell. So please don't take this as an attack.

      But just because public space development is good does not mean that NASA is bad, or that bad things happening to NASA are good.

      I see a lot of people on slashdot, seemingly mostly libertarians, who seem to be cheering anything bad that happens to NASA on the theory this is somehow a victory for private space development. It isn't. This is not a zero sum game. NASA's loss is not private space development's gain. A gain for private space development is a gain for humanity's involvement in space; a loss for public space development is a loss for humanity's involvement in space, but nothing else.

      The things NASA does in space don't supplant what private enterprise would be doing, they supplement it. NASA's goals in space are-- or should be-- to do the things that benefit humanity but which no clear profit model exists from. Meanwhile the advancements NASA creates in space can-- or should be-- models for private enterprise. NASA could and should do more to explicitly encourage private space development and explicitly see themselves as to some extent partners with private space enterprise (I don't know who owns the technology NASA uses in space, I assume the aerospace contractors who built everything do, but I think that technology should be publicly documented and the patents available to the public for use by private operators, since after all the public paid for it) but even as it is private space development can and will benefit from NASA and its presence, and vice versa. Private space development and NASA aren't enemies, this isn't football.

      Meanwhile even in the areas where the actions of NASA and private space operators overlap, private space operators simply aren't ready to replace NASA even if they should. Private space development shows great promise but it is truly at an infant stage.

      Aside from the above, I'm not disagreeing with what you're saying; you may well be right about salvaging or reclaiming Hubble. looks like Hubble will be entering the atmosphere sometime between 2010 and 2032. [wikipedia.org] They're not there now, but it seems likely private space enterprise may get to the point where they can rescue it before it is lost forever even if NASA isn't interested...

        Most libertarians I know don't think NASA is somehow inherently bad -- there are far worse examples of federal money being wastefully expended. As for myself, I really like a lot of the things NASA has done, especially with the Mars Rovers and Cassini.

        The problem many libertarians have with NASA is that they've completely destroyed the spaceflight market, so it isn't like anything remotely resembling a thriving free market. When NASA needs to get a person into space, they don't do it by simply buying a ticket from a rocket launch company which offers the best combination of reliability, quality, and cost. Such a solution would be highly favored by libertarians, as it would operate within the market and would help ensure a steady decrease in launch costs and an increase in reliability.

        Rather, what NASA does is give a cost-plus contract to one of the aerospace giants (Boeing, Lockheed, etc.) to develop a launch vehicle. With a cost-plus contract the aerospace giant has absolutely no incentive to decrease launch costs or exercise any sort of fiscal restraint; it's actually quite the opposite, as the more money the contractor uses up the more money pads their pockets. The fact that the launch market has been so distorted by contracts like this prevents private spaceflight companies from effectively competing and keeps launch costs absurdly high.

        The only reason a private space market is starting to emerge nowadays is because NASA has pretty much no interest or influence on the suborbital tourism market. This will allow market forces to actually come into effect.

        Personally, what I'd like to see is for NASA to stop with cost-plus contracts and act as more of a customer within the market. Things like the Centennial Challenges [nasa.gov] are great, where companies are paid a flat amount based on results, rather than however much they say they need to develop a solution.

          Since NASA launches account for less than 10% of all launches - that's an astonishing accomplishment. (Most space launches are commercial launches, commsats and the like.) The DoD (Which is also non-NASA) accounts for another 8% or so.
          When NASA needs to get a person into space, they don't do it by simply buying a ticket from a rocket launch company which offers the best combination of reliability, quality, and cost.
          If such a rocket launch company existed, NASA would undoubtedly buy a ticket from them. But no such company exists. (Many have tried to get into business, but they've invariably found it to be very expensive - and with little return. NASA doesn't fly often enough to make it viable, and there is no destination for non-NASA flights.)
          Rather, what NASA does is give a cost-plus contract to one of the aerospace giants (Boeing, Lockheed, etc.) to develop a launch vehicle. With a cost-plus contract the aerospace giant has absolutely no incentive to decrease launch costs or exercise any sort of fiscal restraint;
          ROTFL. The last launch vehicle NASA paid to develop was the Space Shuttle.

          The Atlas and Delta that are the prime candidates to launch the CEV? Developed by commercial enterprises, for commercial enterprises, with their own money. The problem however is that launch rates aren't really price sensitive. Boeing or Lockmart could spend millions cutting launch costs by 25%, and only get a 5-10% (if any) increase in launch rates. That's a net loss for them. And commercial enterprises don't generally lose money on that scale on purpose.

          The fact that the launch market has been so distorted by contracts like this prevents private spaceflight companies from effectively competing and keeps launch costs absurdly high.
          Boeing, Lockmart, and others (all private companies) have been competing in a free and open market for thirty years. It looks to many as if it's not effective competition as they don't understand how a limited demand, price insensitive market works - it's not like hamburgers or cars.
          Personally, what I'd like to see is for NASA to stop with cost-plus contracts and act as more of a customer within the market.
          You mean the way they've bought the majority of their launches (I.E. expendables) for thirty years? You mean the way they are planning to for the CEV?

          All I can conclude is Libertarians don't understand economics.

      though, what would be more intresting would be if they could fix it with an unmanned probe or contract it out to russians.

    Got to make you wonder just how safe the shuttles are when the primary risk isn't repairing the Hubble telescope but being on a shuttle in the first place. Two blow up and now they hesitate to take them up unless it's in an orbit that crosses with the space station. After the Challenger I said I'd go up the next day on one because I trusted NASA. Now I'm not so sure. Sad because they used to have one of the best safety records in history given the massive risks involved in any space mission.

Unfortunately I'm afraid of who his replacement will be, especially since his replacement seems to be coming in as part of a program to cut out what little science is left in NASA's programs in order to dump all the budget to a vague "let's go to mars!" plan that seems about as well-conceived and likely to turn out as planned as any of those five unsuccessful shuttle replacement programs NASA blew its budget on at the end of the 90s.

    # Why doesn't it look like a mirror? This mirror was never used, so it never received a reflective coating. The mirror in the Hubble was coated with a thin layer of aluminum and also overcoated with magnesium fluoride, so it could better reflect ultraviolet light.
    # What is it made of? The mirror is made of Corning ultra-low expansion glass. The front and back surfaces are fused to a lattice core and to the inner and outer bands, creating a sturdy but lightweight structure.

      You obviously have no clue what you are talking about, there are many wavelengths that can't be covered from the ground and that are not properly covered by and other space telescope, specially in the UV.

      Hubble has some other great advantages over any ground telescope: a much darker background, and possibility of _much_ longer observation times, for certain things this is not important, but for other tasks this is _fundamental_.

      When you request some time at Hubble you already have to explain _why_ that task can't be done in any other way, so Hubble is already being used only for things that can't practically be done with anything else.

      And JWST wont help with this, because as anyone with a clue knows, it's designed to _complement_ Hubble, not to replace it, and their capabilities do not overlap.

      Currently there are not even plans to build anything that could replace what Hubble provides.

      And for those that say that Hubble is old, thanks to the previous Shuttle missions to it, many of it's instruments have been replaced with much better and improved versions keeping it at the front of the state of the art.

It's the process of doing it that seems more important than the "End Result".

    The CAIB did a fairly large number of risk asessments for returning the Shuttle to flight. That covered just basic flight and the risks involved. The numbers for Hubble would be essentially those numbers.

    I rather suspect that the risk analyis for Hubble would be something along the lines of "For non-strategic flights on Shuttle, we have to have a 99.5% chance of success". Since the baseline Shuttle analysis for the risks on return-to-flight are already outside that boundry, then it makes zero sense to spend money digging deeper.

    Loose consensus at sci.space.tech is that O'Keefe's decision has virtually nothing to do with safety and everything to do with the extremely tight schedule necessary to complete ISS (International Space Station).

    O'Keefe stated that he would abide by the Columbia Accident Investigation Board (CAIB) report. My understanding is that board did not insist that the Shuttle be able to seek refuge at ISS.

    It's interesting that the article speaks of "risk" but doesn't explicitly use the term " safety risk" which is assumed. Indeed, the risks of any extra Shuttle flights go beyond the safety of the crew. Consider that the Shutle's only mission is ISS assembly after which the fleet will be retired -- and rightfully so. If a Shuttle were even to be reparably damaged with no injuries to the crew, the ISS program would be seriously threatened.

I, for one, will continue to be interested in the heavens. As was said in my favorite commercial: "We've always watched the stars. If you look at the sky you can see the beginning of time."

    Basically, there are two sides to this story. First of all, any kind of talk about risks is complete bullshit. The risks are no greater than in all previous Shuttle missions, and flying within docking distance of ISS is not a magical solution that somehow makes the risks becaom significantly smaller. It's just that NASA became so politicized, that they routinely use purely political tricks, and this talk of risk is exactly that. They are just repeating their routine after the Challenger accident: back then it turned out that the Shuttle's lack of emergency escape system proved to be a bad idea. So, their solution was to invent a bogus, unuseable escape system to make everybody shut up. The only thing this system is good for, is torturing the crue very creatively for PR purposes. And now they came up with the "if it breaks, we'll dock at ISS" solution. A complete garbage. On the other hand, NASA is right in one thing: Hubble IS NOT WORTH REVIVING YET AGAIN. It's better to let it die gracefully and replace it with a new and better telescope. A Shuttle mision to repair Hubble is, at this point, a complete waste of resources and a tremendous hinderence to the NGST program. In short - NASA became a purely political organization, one that is incapable of telling people the hard truth, and consistenyly choosing to replace it with sweet lies. And this certainly didn't happen just yesterday. :(
  • I remember reading an earlier story here about the estimated cost to send humans to mars in the 70-90 billion dollar range. Bush during re-election pledged about a 3 billion dollar increase and a new long term mission.

    Obviously funding to fix hubble had to be cut to pay for the shoe string budgeted mars exploration.

    The safety hazard is really a coverup.

    I'd like to take this opportunity to remind everyone about the Hubble Origins Probe, a proposal to replace Hubble with a cheaper and better (and, dare I say, faster) craft:

    An international team led by Johns Hopkins University astronomers have proposed an alternative [spaceref.com] to sending a robotic or manned repair mission to the ailing Hubble Space Telescope [wikipedia.org]. Their proposal is to build a new Hubble Origins Probe [jhu.edu], reusing the Hubble design but using lighter and more cost-effective technologies. The probe would include instruments currently waiting to be installed on Hubble, as well as a Japanese-built imager which 'will allow scientists to map the heavens more than 20 times faster than even a refurbished Hubble Space Telescope could.' It would take an estimated 65 months and $1 billion to build and launch, approximately the same cost as a robotic service mission.

    Here's the official web site, with slideshows and posters explaining the planned scientific instruments:

    http://www.pha.jhu.edu/hop/ [jhu.edu]

    In my opinion the original Hubble is mostly valuable for sentimental/historical reasons. From a pure cost/benefit analysis, replacing it seems the best solution in pretty much every possible way.

    The political fallout from a disaster during a Hubble repair mission is something NASA can't absorb. No risk analysis can act as a buffer between NASA and a disillusioned public and a Congress full of people looking for reasons to gut NASA.

    O'Keefe's decision was a political decision made for political reasons. Choosing not to fly the Shuttle's most dangerous mission was the right decision in the aftermath of Columbia. Not a popular decision, but the right decision.

    Risk analysis is an engineering tool, but leading NASA is not an engineering task.
    • The Shuttle's most dangerous mission was Centaur, which would have put a fully fueled liquied booster in the payload bay - at a few tons over the rated capacity of the launch vehicle. It was cancelled in the wake of the Challenger accident, and I heard none of the engineers wishing it hadn't been...
      "...not an engineering task".
      Actually, we refer to some forms of management as "electropolitical engineering".

    But a friend of mine (and a robotics engineer) made a good point: Hubble sure kicks ass, but we've got bigger and better technology now. Maybe we can spend all the "Hubble Rescue" money on something even more impressive, which would yield even better imagery than our good ol' HST.

    NASA officials have stated publicly the agency's decision to cancel further servicing to Hubble was made on safety issues alone, not cost.
    I hope so, I don't want to think that it's too expensive to save lives...the article rewords this same position 7 times in a row as if there's something wrong with this position.
    As Gregory told Congress, "Administrator O'Keefe made a very conscious, deliberate and well-informed decision that the shuttle would not service the Hubble."

    ... "NASA historian Steven Dick ... revealed that, in fact, no formal risk analysis had been completed."
    This doesn't say anyone claimed there was a formal document generated. One can be well-informed without lots of formal paperwork.
    The decision was made (by O'Keefe) based on what he perceived was the risk."
    Sometimes it's just a no-brainer. Why strain over it?
    For example, according to ... anonymous, one company actually proposed using an updated version of the module that was built in the 1990s to allow the shuttle to dock with Russian Mir space station...so the crews could be transferred from one spacecraft to the other in a shirt-sleeve environment...
    Docking between human life support systems is irrelevant. Hubble is not a human-bearing spacecraft, and has no "inside" to dock to, no airlock. The piece of equipment mentioned here is as useless to fixing Hubble as it would be to fixing the engine of your lawnmower.
    O'Keefe testified before the National Academy of Sciences in June 2004, he made no mention of this docking module option, telling academy panel members that the only method available for crew rescue was a spacewalk
    Since there's no "inside" of Hubble, the repairs have to be made from the outside of Hubble, like your car has to be repaired from the *outside* of the engine, this was and will always be true. So a spacewalk is the only way. Kinda like getting wet is the only way to swim.
    Nor has NASA ever apparently considered the idea of using one of the several available supply modules to supplement the provisions of an orbiting shuttle...such a module could be used as a supply depot for a damaged shuttle - a form of safe haven ..."
    A "supply depot" is not a "safe haven" - it's a spare parts cabinet. A "safe haven" would be a second working space craft that could replicate all the functions of the first, otherwise, if something goes wrong, you have two sets of problems: the limits of the disabled vehicle, and the limits of the "safe haven". If they both can't do the same thing at any point, you're dead. Redundancy for safety must be planned in total in advance, or it's useless.
    ...thereby extending its time in orbit ...
    Having a safe haven does not lengthen the time the orbiter can stay in orbit - same as the "supply depot" situation. The redundancy is not there to be relied on for primary mission objectives, but to bail you out if needed.
    Two such supply modules...are under development ...
    Now we know why they weren't considered. They don't exist yet.
    As Rep. Mark Udall, D-Colo., noted during those same science committee hearings, "If we're unwilling to take the risks to go to Hubble, then what does that say about (our willingness to mount) a moon and eventual Mars mission?
    It says that we recognize that the shuttle's old and busted technology left over from the 1970's and if we're gonna do something bold, we gotta do it with new hotness. I could go on, but I think I've made my points....
    • I could debate each of your points individually, but that would take more time than you appear to have put into understanding the story.

      On your comments about no need for formal risk assessment;

      Basically, I don't believe that having a scientific risk assessment done would be all that foolish when deciding between various possibly multi-billion dollar options. It is becoming more and more clear that O'Keefe made the wrong judgement; of the groups that have since looked at the issue, now including the Nati
      • I was thinking the story was about the title: "Backing a bad HUBBLE decision". shuttle-to-shuttle docking has no impact on Hubble repair mission, because Hubble isn't a space shuttle.
        Since no one has ever done a "rescue mission" of one manned space craft using another manned space craft (with the possible exception of a few of the trips up to Mir), designing everything needed to make it work, and to make sure it would work under most plausible failure modes would take far longer than Hubble can wait.

    This was clearly a judgment call, not due to a formal analysis. NASA doesn't want to repair the Hubble, for various political and technical reasons.

    And why should they do a formal analysis? The whole point of making Hubble human-serviceable was probably to serve as another ustification for the shuttle program. The rational, low-risk decision would have been to start planning on sending up an entire replacement telescope years ago, for less money and less risk than the service missions.

    So, why start now with formal cost/risk/benefit analyses? No manned mission would survive that kind of analysis at this point: at this point, it's pretty much always cheaper and less risky to achieve whatever scientific or technological objective we have with unmanned missions.

    This doesn't surprise me at all. What surprises me is that people continue to remain oblivious to the obvious and in denial of the damning. O'Keefe's decisions do not represent NASA, they represent the Bush administration. People seem to assume that because he was a NASA administrator then his decisions reflect those of NASA, well NO, he's a politician who joined the Bush administration on its very first day and whose niche is spinning budgets wherever he was dispatched to serve their political objectives. Does it surprise me that he made a decision without a formal study of the technical and scientific issues? No more so than the policies of the Bush administration on climate change that continue to ignore and defy all scientific and technical consensus, or for that matter, on embryonic stem cell research, the economy, or other issues. This is an administration that's driven by dogma and electoral politics. This is an administration whose core electorates and campaigners include evengelical creationists who continue to believe that God created man and woman 6000 years ago and that creation as told in Genesis ought to be reintroduced to science curriculae and taught to school children. This is an administration headed by a president who asserted that "On the issue of evolution, the verdict is still out on how God created the Earth", which is an even more explicit assertion than the creationist campaigners' own "evolution is a theory, not a fact" stickers that they want on schools' science books. Anyone who cares enough about science to study its history and how its epistemological method came to be what it is today will be clear in knolwedge and mind that for many centuries from Copernicus through Kepler and Galileo and to Haley and Newton the the history of science was none other than the history of astronomy; the history of the struggle between the scientists who directly observed the heavens with their eyes and telescopes and the clergy who derived their authority from the scriptures that they claimed came from those very same heavens. Telescopes were the defning instrument of science that eventually led to societal secularism through Descartes and Bacon and Hubble is simply a fancy version of Galileo's own instrument that continues to inform us on how we came to exist by eyeing the birth of the universe that's evident in its distant depths and giving further credence to secular teachings, and many of Hubble's findings have found their way into university and school curriculae already. Anyone who believes that money for the Hubble servicing mission can not be found by an administration that provides tens and tens of billions in "faith-based initiatives" that amount to nothing more than handouts to their core campaigners and that deliberaly runs a budget deficit of hundreds and billions that will lead to nothing less than the cold-blooded collapse of the humanist institutions of social security and welfare programs is out of his mind. This is kleptocratic administration that seeks to reverse centuries of humanist progress and return us to our "original foundation" of being under the mercy of a criminal clergy and under the dominion of a militant marcantile. I suspect what I have written above may invite the diatribe of a kukluxitious clan whose ideas of political conduct derives from their tribalist tradition in spectator sports and who approach reasoned debates with the mentality of a dogfight, but I couldn't care less about responding to them, for it is all futile to reason with dogs, and they'll eventually get what they deserve in their trashtastic future from a political elite who couldn't care less about them beyond the expolitation of their mass stupidities.
  • I don't understand, is it just incompetence or is there a global anti-space conspiracy... Russian government and the space agency did exactly the same with Mir. No transparency, few solid arguments, no impartial studies. Just an arbitrary final decision - "Dump it into the ocean". A useful tool destroyed for no apparent reason at all.
