Commission Says NASA Failed on Shuttle Safety 232

Posted by timothy from the spaceflight-so-far-not-perfectly-safe dept.
Tsalg writes "The final report from the Stafford-Covey Commission concludes that out of the 15 recommendations they made, the 3 toughest technically are not met. The news was not official on the return-to-flight website but has been widely commented elsewhere. Says one of the task members: "It is NASA's job -- not the task force's -- to determine whether the risks are acceptable and whether it's safe for Discovery to fly." The commission said risk remained that pieces of foam and ice could break off and hit the shuttle at lift-off. It also said the orbiter had not been sufficiently hardened and it lacked an in-flight repair system.Nasa has been aiming to launch shuttle Discovery as early as 13 July."

    and honestly, does NASA have the billions it'll take to fix the shuttles up again? Will the public even care to pay for a program that would be down another two to three years? Five years between shuttle launches?

        Private companies will almost always pursue goals that will make them money in the long run. Corporate moguls are now catching on to the fact there's a lot of rich people out there willing to spend $250K for a quick flutter into orbit.

        Space programmes with ulterior motives than profit will likely always have to be finianced by the people, through governments.
      • Define failure

        Are we talking a complete mission loss? An abort leading to reduced mission capability? What about a return to launch site abort? Technically an abort is a failed mission, but if it is dealt with, it is, to paraphrase Apollo 13 somewhat, a successful failure, because a problem is dealt with and everyone is safe.

        What problems do you think would be bad enough to consider this mission "fucked", so to speak :)

    • The shuttle missions assume that manned flight is required for research in space - in this day and age, that supposition should be questioned.

      If the US government can not regularly and reliably put and retrieve people from orbit, we need to look at the alternatives such as private missions or a return to exclusively unmanned research - both of these have tradeoffs, but the cost to the taxpayers and the beauracracy involved goes WAY down as soon as you take people out of the equation.

    If we wait until there are no risks the shuttle will never fly again. If we wait until everyone agrees with the risks, the shuttle will never fly again. We gave NASA the task to explore outter space, lets give them the ability. They understand the job at lot better than most people. The people who want to fly understand the risks. Lets let them take the risks if they think its worth it.

      yes... well 2 shuttles with crew have died so far. I mean a: yes going into outer space is risky, but 2: if they are going to go we should stop forcing them to use the technology that really isn't fit for the task. The shuttle system is a reagan remnant, like star wars and the stealth bomber and a lot of other things that were designed PURELY to scare the russians with our way overengineered tech. seriously, that was their job, they were made with the design principal "oh and put a bunch of sharp black pointy things on the front to scare the shit out of anyone who sees it" (note the soviet's tried to come up with a copy, they never really could get it to work, and it cost so freaking much they stopped trying, and they are arguably better at space than we are). The SR-71 was made in a similar vein with the only difference being it actually worked, check out combat ready ratings on B-1's sometime.

      I think we should let NASA make their own call, but we aren't, we're forcing them to play gay govt accounting games so the investment in the current shuttle program, and all its maintainance look good, and costs us over $1B a flight. Commercial sat launches go for under $50 most of the time, and are much more flexible regarding orbits. Create a new heavy-lifter, or even bring back the Saturn V, because even at $1B a shot, and counting all the cash we put in for upgrades and maint it's still way way way down the line in terms of launch vehicle capabilities. A Soyuz system is actually safer for docking with the ISS, and half the other things you need to do in space.

      The shuttle was well designed in the beginning, but all the modifications to baselines due to budget pork, politcal conprimises, and simple age have made it unfit for it's duties. You wouldn't ask jet pilots to patrol the skies in p-51 mustangs because we already had some, and north american aviation was an important constituent of the chair of the commitee for armed services, why are we sending our astronauts up in vehicles that are unable to perform their real requirements, and are also designed for size and looks over safety and functionality? Also, would you rather have 1 big ship that can be launched twice every year or 10 small ships that can be launched monthly with the same overall benefit?

        You're asking the wrong question. The proper question is: Would you rather have one ship that has a 2% risk of complete destruction, or no ship at all? This is the question we're trying to answer. Bringing up some theoretical ship that doesn't exist is interesting, but not relevant to the discussion right now.

          And Buran worked fine, and was in many ways superior to the Shuttle - it, for example, contained jet engines that allowed for a powered landing - Shuttle can't pull up for another landing attempt, Buran could. It also had no main engines - they were in the huge booster that mimic the shuttle main fuel tank. Buran also had no firecrackers (solid rocket boosters), and instead used only liquid fuels - making challenger-style boom impossible.

          Yes, it was an aerodynamical copy out of stolen blueprints - so they saved a ton of wind tunnel testing and other stuff, but the innards were all russian tech, and they make good solid space tech.

          What didn't work out was the funding. Shuttle is expensive, and so was Buran. Collapsing USSR decided to save SOME kind of space program, and picked MIR and the trusty old rockets they had already in service, and canned Buran. It only flew once, unmanned. A feat Shuttle can't do, by the way, as it can't land unmanned.

          Considering how expensive Shuttle is to operate, I'd say they made a smart financial call :)

          But there were no technological obstacles. It was only the lack of money. A real shame what they allowed to rust in the former USSR - they had the biggest booster (Energiya) and the 'better' Shuttle, but both are now pretty much gone due to lack of funds.

            The shuttle has at least proved that an unpowered landing is perfectly safe. It would be absurd to add the weight cost of engines and fuel just for a go around capability. A robust flight control system is far more efficient. Buran also had no viable electrical power generation. The vehicle was stuffed with batteries on its only flight! That is why it only ever flew a single orbit. So much for the "better" shuttle. It was a child's replica initiated by a paranoid Leonid Brezhnev. The Russians still do not use fuel cells 40 years after they were introduced on American Gemini spacecraft.

            It also had no main engines - they were in the huge booster that mimic the shuttle main fuel tank.

            ..Making Buran one of the costliest and wasteful launch systems ever conceived. Each Energia flight threw away the 4 main H2O2 engines and 4 Kerosene/O2 boosters none of which was reused. Compare this to the shuttle where the SRB motor casings and the SSME's can be used many times.

            Buran also had no firecrackers (solid rocket boosters), and instead used only liquid fuels - making challenger-style boom impossible.

            Since Challenger, the SRBs have flown 176 times with a perfect safety record. I have always questioned why solid fueled boosters are looked down apon for human space flight. The new NASA administrator is almost certain to favor a derivative of the SRB for a CEV launch capability. You often hear that liquid fueled rockets are safer because they can be shut down. As a passenger in hypersonic I would not be happy to be flying hypersonically next to a highly pressurized fuel tank and have a malfunctioning engine shut down. That was ok on the Saturn because of the series staging and spare thrust capacity. But on the shuttle with parallel staging such a booster shutdown would be deadly. Such "firecrackers" will very likely be the basis of a launch abort system as well. That alone says something about the safety and reliability of solid fuel.

            It only flew once, unmanned. A feat Shuttle can't do, by the way, as it can't land unmanned.

            Another foolish and oft repeated misconception. The only reason the shuttle doesn't fly unmanned is the polical clout of the astronaut corps. Do you think a shuttle commander has a hand on the stick at anytime from launch to landing? NASA basically gives the stick over to the pilot when the shuttle is lined up with the runway and has enough energy to reach its end. If humans were not aboard the shuttle would be happy and capable of landing and rollout as well.

              Sure. And overhauling them after each flight has turned out to cost far more than building new single-use engines. US taxpayers have been soaked for countless $Billions over 3 decades in this epic demonstration of the phrase "penny wise, pound foolish".

      When NASA engineers decide a risk really is unacceptable, NASA beurocrats have to stop and listen. I have no problems with NASA taking risks - space is a risky business. Life is a risky business. It is when politics override those engineers on the ground that I get concerned.


      Think - when are the two times the Shuttle has been dsestroyed? Challenger, when NASA bosses decided that freezing temps were fine, because they had a propoganda coup going with the school teacher, even though engineers were screming at them, left, right and center, to postpone the launch and check for damage.


      Columbia was lost - when? During NASA's other attempt at a propoganda coup, with getting an Israeli into space. Engineers wanted images of the wing, to check for damage. The intelligence agencies even offered to produce the pictures for free. But the NASA bosses - again - put the risk of bad publicity as being more important than the risk of a disaster.


      Take risks - take as many risks as you want or need, to get the space program into a functional state - but please don't take risks with other people's lives because you want your photo on the front page of a newspaper. If it works, it achieves nothing and is lousy management. If it fails, it sets everything back and is catastrophic management.


      I don't agree with the NASA bosses deciding that they should overrule the safety monitors, because the safety monitors' chief objection is that NASA bosses keep overruling things they shouldn't. It somewhat defeats the purpose of the exercise, if NASA repeats the very worst "crime" of all, in an effort to move forward.


      I do agree, though, that the shuttle won't ever be 100% safe. It is a 1960s concept, built around 1970s technology (and having spoken to people who have built components for it, not very good technology at that), and it urgently does need retiring with something better. It's a pity Congress has cancelled all the replacement Shuttle programs, through budget cuts, or we'd have one by now.


      Hey, Congress isn't the only bad boy. If Britain hadn't scrapped HOTOL, we would have had a replacement shuttle program years before the Columbia disaster, the ISS would likely have already been completed, and space technology would be easily a decade ahead of where it actually is. (We would also have commercial space travel by now, as HOTOL would have been damn good at that, as it was a design consideration.)


      I also agree that NASA has made all the changes that are going to make a substantial difference, so that any further delay would be pointless.


      There ARE a few things NASA could do to improve things, though - ice buildup is only a problem if there's enough humidity in the air for the water to form ice. It shouldn't be too hard to build what would be basically oversized hair-dryers to blast warm dry air over the top of the tank. At worst, there would be less ice, at best there would be none at all.


      How long would it take to plug a hair-dryer in at the top of the launch tower? My guess is not very, even if it is very large. Switch it off before launch, so there's no weird air currents, and you should be fine.


      This simple addition would not only cut back on ice, but should also cut back on foam risks, because the foam wouldn't be rigid and unusually heavy by being blocked up by ice.


      I'm sure NASA engineers have proposed - if not this scheme, then countless others that are similar in nature. They're not dim, even if it seems that way at times, and know perfectly well that ice is water, and therefore if there's no water, there's no ice. They also know that warm air will expand into cold air far more readily than the other way round. (Pressure * Volume / Temperature = Constant, so if you double the temperature, you double the pressure. Air flows from high pressure to low pressure, on average. The rest, as they say, is obvious. :)


      Leave space exploration to NASA and agencies and private organizations like it. Yes. Definitely. But PLEASE, will NASA and the others PLEASE leave the technical decisions to the technical experts and NOT to the P.R. crew? Doctors of spin are not necessarily doctors of physics or aeronautics.

    Nasa still has an exemplary record. Only 2 crashes in 20 years. I have no idea how many missions that is, but it's not a few. If you want the people we send up to be safe, give NASA some money, and stop whining about how unsafe it is.

    What NASA needs most is a good dose of competition. It worked wonders for Detroit. Ford, GM, and Chrysler produced shoddy vehicles for nearly a decade until Toyota, Nissan, and Honda drove the American companies to the verge of bankruptcy. Then, they transformed themselves into competitive powerhouses that producing outstanding products. The quality of American autos now approaches that of Japanese autos. (American cars continue to lose marketshare to Japanese cars due to poor ergonomics and ride feel, not due to quality.)

    So, who or what could serve as competitors to American companies bidding on NASA-funded projects? The answer is Japanese companies that build Japan's rockets and satellites. In the future, NASA should open up future missions to competitive bidding among both Japanese companies and American companies. NASA maintains a hands-off approach. Future missions will be mostly private ventures run by private companies but subsidized by government funding.

    The mostly-private approach also involves one additional element: lawsuits. If future space mishaps occur, the company running the space mission or building hardware for the mission will be subject to lawsuits by the families of the victims.

    Private companies will bear the responsibility for the success of the mission. NASA acts only as the funder. Competition and lawsuits can do wonders in producing a reliable product. Just look at American automobiles with their high quality and vast arsenal of safety features: air bags, crumple zones, etc.

    Well, the first thing that strikes me is that the panel head (RIchard Covey) himself (were he younger and still in the flight program) wouldn't hesitate to fly on the revamped shuttle. So NASA fails the appointed checklist of improvements, but doesn't fail a former astronaut's 'gut instinct' test.

Also, well-written and heartbreaking.)

    EXECUTIVE SUMMARY

    It has been 29 months since Columbia was lost over East Texas in February 2003. Seven months after the accident, the Columbia Accident Investigation Board (CAIB) released the first volume of its final report, citing a variety of technical, managerial, and cultural issues within NASA and the Space Shuttle Program. To their credit, NASA offered few excuses, embraced the report, and set about correcting the deficiencies noted by the accident board. Of the 29 recommendations issued by the CAIB, 15 were deemed critical enough that the accident board believed they should be implemented prior to returning the Space Shuttle fleet to flight. Some of these recommendations were relatively easy, most were straightforward, a few bordered on the impossible, and others have been largely overcome by events, especially with the decision by the President to retire the Space Shuttle by 2010.

    The Return to Flight Task Group (RTF TG) was chartered by the NASA Administrator in July 2003 to provide an independent assessment of the implementation of the 15 CAIB return-toflight recommendations. An important observation must be stated up-front: neither the CAIB nor the RTF TG believes that all risk can be eliminated from Space Shuttle operations; nor do we believe that the Space Shuttle is inherently unsafe. What the CAIB and RTF TG do believe, however, is that NASA and the American public need to understand the risks associated with space travel, and make every reasonable effort to minimize such risk.

    Since the release of the CAIB report, NASA and the Space Shuttle Program have expended enormous effort and resources toward correcting the causes of the accident and preparing to fly again. Relative to the 15 specific recommendations that the CAIB indicated should be implemented prior to returning to flight, NASA has met or exceeded most of them - the Task Group believes that NASA has fully met the intent of the CAIB for 12 of these recommendations. The remaining three recommendations were so challenging that NASA could not completely comply with the intent of the CAIB, but conducted extensive study, analyses, hardware modifications, design certifications and made substantive progress. However, the inability to fully comply with all of the CAIB recommendations should not imply that the Space Shuttle is unsafe.

  • I suppose all the engineers walk around the building wearing helmets and kneepads.
  • Doesn't this whole thing seem like a waste? The shuttles will be permanently grounded in 2010 because its flight certification will expire, and it is generally agreed that it would be ridiculously expensive to get it re-certified. We're half-way through 2005, so they have 4.5 years left of flying. It seems like they have a tough time getting more than a few flights a year out of them. So, being optimistic, they might get another fifteen flights out of these shuttles. They have so far lost aprox. one in
