NASA Admin Says Shuttle and ISS are Mistakes 642

Teancum writes "NASA Administrator Michael Griffin was recently interviewed by the USA Today Editorial Board regarding the current direction of the U.S. Space Program, and in the interview he suggested that the past three decades have been a huge mistake and a waste of resources. As a total cost for both programs that has exceeded $250 Billion, you have to wonder what other useful things could have been developed using the same resources. Griffin quoted in the interview regarding if the shuttle had been a mistake "My opinion is that it was... It was a design which was extremely aggressive and just barely possible." Regarding the ISS: "Had the decision been mine, we would not have built the space station we're building in the orbit we're building it in.""

    Not that I want to defend, or indeed offer any opinion, on any particular war (it's OT for a discussion of the space program), but war drives our knowledge of science and engineering (and new technologies) as well as, or possibly better than, the space program.

    Think DARPA-derived Internet, and GPS.

    Yes, Freedom was supposed to be in a different orbit that the Russians cannot reach, but it would have been disasterous after the Columbia accident, as either the Shuttle fleet would have had to have been flown with a known (and now highly public) flaw or grounded and the station abandoned for the interim period. Could NASA have gotten away with flying Shuttles after Columbia?

    When people state that a arguably successful endeavor was "was extremely aggressive and just barely possible", I have to wonder exactly what is behind the statement. The shuttle has been successful on a number of fronts, too many to list here. Yes, exploration is a dangerous business--an not just space exploration. You can always look back in history for dangerous expeditions and high casualty rates. Test pilots, famous historical exploration, modern-day exploration (in space, underwater, and caves), unnamed and unrecorded Viking, Chinese, Phoenician, Portuguese, and Polynesian explorers, etc. I am sure you can find many harrowing tales of death and suffering in the name of exploration [kidinfo.com]. I am sure there are a number of tales of failed Colonial settlements [wikipedia.org] which ended tragically. It makes me wonder if we have lost our tolerance for casualties in the name of science and/or exploration. If it wasn't for seemingly foolhardy or impossible endeavors, would we have really learned anything of value?

    This is not meant to be a troll. I love the space program and everything about it. But I do have a serious question to make sure I'm not overlooking something.

    At this stage of the game, what is it that we can do on Mars with a manned mission that we cannot accomplish better, cheaper, and safer, with a robotic mission?

    I really don't see a point in a manned mission to Mars until we've been on the Moon long enough to have a permanent station of some kind there.

    As much as I loved Apollo, I'm not sure I see that it really accomplished anything with manned missions that a robotic mission couldn't have done. Especially since if I'm not mistaken only one or two real 'scientists' went on any of those missions.

    The problem isn't overinflated budgets, it's poor management of those budgets. People who design soemthing turn around and say "hey look, we need more money to keep going, this is going to be more expensive"; make them quantify why it will be more expensive, come up with a list of alternatives, and make these people work for the money they're getting.

    If Scaled Composite was handed a check for 250 Billion they'd wet themselves, hire a ton of new engineers, and start on their way to becoming NASA. But forcing them to work with a small budget makes each and every bolt a considered cost, and a lot more streamlined.

    Personally, I'm of the opinion that Scaled Composites can do better than NASA, but it will take some self control when it comes to spending, designing and testing. But I would be greatly disappointed if they were handed a huge check for a quarter trillion dollars.

    Thanks for pointing this out. I was doing some research on NASA knowledge management a while ago, and I came across a quote to the effect that "The Shuttle was built to supply the ISS, and the ISS was built to give the shuttle someplace to go", which I think fits in pretty well with what you mention. The only thing I'd disagree about is why Bush is talking up the Moon/Mars again - I think it has little to do with China, it's just that he knows it sounds good and inspiring, but all the real problems and expenses will be safely pushed onto his successors.

    Freedom was foreseen as primarily a US venture for launch and support, as already indicated. Ascent from French Guiana was possible (they were our friends, right?) without too much trouble in a 28.5 deg inclined orbit, but it took a fair bit of delta-V to get from Baikanor to 28.5 deg. Of course, that wasn't our problem as the Soviets were on the other side.

    OK, international politics aside.

    One of the real problems we saw was the US Congress, and yes, NASA management.Space Station Freedom was often a dumping ground for "retired in place" senior engineering management waiting for that magic day when they could sit at home and impede their wives instead of coming to the office and impeding engineers. That's not to say we didn't have decent, enthusiastic, qualified management but they were outnumbered... or simply out-numbed... by the incompetents.

    A lot was preordained, despite engineering advances. "Don't try to convince me, my mind is made up." I could go on at length about the decision to scrap the 100 khz power distribution system on Freedom in favor of the DC system. I was around when the "test" destroyed some computer hardware at MSFC that was used as justification, despite the fact that the test was protested by competent engineers with a knowledge of VAX power supply design. Were there problems with the high frequency AC distribution? Some, but not insurmountable.

    SSF was also a training ground for kids right out of college. Get them in, turn 'em loose with little guidance, slap 'em around a bit until they started doing good design, then move them to Shuttle.

    We had a lot of design by Aerospace Conglomerate, too. Let's get that design that Lockheed wants, because it'll make them easier to deal with at contract time. Let's use THIS design that MD wants, even if it's not what NASA wants/requires, because we think their design is going to make them do something else for us on another project.

    Still, and all, most of the conglomerate designs I saw, worked with, and helped shape (and, yes, I worked for a contractor company, too, but I was doing specs and requirements, as well as working with the prototyping) would have been acceptable, even if somewhat limiting in their own ways.

    The BIG problem, however, was Congress. Every three years or so, we'd get a "stop what you're doing, reassess the design, and then start over" command from the Hill. I've gotta say, we wasted a LOT of money on those exercises, and we wasted a LOT of time.

    There are improvements borne of waiting time and engineering advances in ISS that would not have been, and may never have reached SSF or Alpha, but we could well have bent metal and flown hardware by 1990 if Congress had stuck to original budgets and timelines and stayed the hell out of the way. I flew prototype hardware in 1992 that was the first piece of Space Station hardware to fly, be proven and certified for on-orbit Space Station operation. I could have flown it 3 years earlier save the Challenger accident.

    Final thought. We developed or promoted a lot of stuff that's now common place in the world. Speaking from the perspective of medical hardware development (I also did a bit for the medical facility in terms of GNCC and COMMS) there's a lot of stuff I see in hospitals, doctors' offices, dentists' offices and ambulances that makes me smile and think, "I worked with the prototype of that...", or, in a couple of cases, "I wrote the SBIR paperwork that made that happen".

    So, yes, NASA's efforts HAVE improved life ont he planet. Really.

    Well, it depends on whether they know what they want to spend it on.

    The first prerequisite of any successful engineering project is to have a worthy goal that is clearly identifiable and governs everything else. In this sense, Scaled Comoposite's acheivement has a lot in common with Apollo, and the Shuttle and ISS have a lot in common with each other. The Spaceship One effort and the Apollo program were both narrowly focused on one thing -- sending one or more humans to a specific place and returning them safely. All the engineering done on them was focused on achieving that goal. The Shuttle and ISS programs, while they support many worthy scientific an technical goals, are primarily driven by pleasing enough constituencies to continue their operation. These are political goals, which means many types of missions under many types of conditions.

    If you had to put the Shuttle's purpose on a bumper sticker, it would be "Cheap Access to Space". Except "Access to Space" is vague. Obviously, we mean "Manned Access to Space", but even stipulating that, different missions under different scenarios require different performance characteristics. The shuttle has all kinds of capabilities that it uses on very or none of its missions; yet all the things needed for those capabilities are shot up to space and landed on every single mission. I'm thinking primarily the wings here, but its large payload capacity and its capacity to launch satellites into polar orbit count here too. It follows that the Shuttle design is likely never to be the cheapest way of doing any mission. But, without the ability to perform a wide array of missions, NASA would never have got the backing of the Air Force, which wasn't really all that interested in the Shuttle.

    You can't design any system to do everything; and the more the system does the more complex costly and unreliable it's bound to be.

    Specific goals such as "get two men higher than 100km and return them to the surface safely" are inherently more efficent to pursue than broad, vague goals such as "build an orbital launch capability" or "cheap access to space". And, this has other consequences. Scaled's accomplishment, while signficant in its own right, gets them practically zero percent of the way to orbit. They just built an air launched rocket plane like the X-15. About the only thing they're almost immediately ready to do is create a suborbital space tourist business. If the mission was "get two men higher than 100km and return them to the surface safely primarily with components that will be part of a future orbital capacity," they'd have spent a lot more money, taken longer, and may not have been as safe.

    NASA used to be the shining example of a good Federal agency. They lost that status after Challenger and instead of regaining it they sank even further with Columbia. The unmanned programs are still doing well. The unmanned propopents say we get a better return on our investment with robots. From a scientific point of view, the answer is yes, but from a public perspective, the answer is no. Without manned space travel we have no visions of space as a frontier. The lure of the frontier is deeply embedded in the American psyche. We look to the people, the astronauts, who enter it. NASA needs to do a better job with it's manned program. The return on investment with a manned space program isn't the same as those of an unmanned one. We need both.

    Basic materials research into high strength cable is one thing, but the Indian Rope Trick notion isn't going to "fly". For example, it's not just the wind and rain from tropical storms you have to worry about, but the lightning.

    Only if you go all the way to ground level. A LOT of different designs have been thrown around over the years; I recall a recent Analog SF story using a high altitude dirgible platform. While it was done in the story to avoid a legal jurisdictional SNAFU, it could be done at a high enough altitude (above 50000' ?) to put the cable entirely above the weather.

    There's another detail... the economics of space transport dictate that whoever is first to build a working space elevator will effectively own space. Natural monopolies occur when there is a high entry cost, and reduced costs thereafter. In almost every design, the main cost element (aside from R&D) is not the exotic materials, but lifting them to orbit-- $100 to $1000 per kilo multiplied by beanstalk cable weight per meter multiplied by a whole lot of meters. A space elevator (capital amortization aside) cuts the costs of space access on a per-pound lifted basis by at least two and perhaps three orders of magnitude. This means once you have one beanstalk, your capital cost for putting up another is vastly reduced.

    Launching that amount of fuel to the ISS is prohibitively expensive.

    Partially due to the orbit that ISS is curently in. Catch-22s are great, arn't they? (Though, really, the major problem is the station is so large it takes a huge amount of fuel to move it anyway, intertia being what it is, and the high speeds involved in orbital velocities would mean you would have to move it a bunch.)

    I just want to point out that a working space elevator solves basically every problem of human civilization. Quickie example: energy. With a space elevator, you power your whole planet with nuclear energy. "but, but what about all that terrible waste???" No problem, you put the waste in beer-keg size container and lift it above geo-sync. Release it such that it impacts the moon at a crater that we've designated as a dumping ground. Absolute worse-case senario, the elevator breaks during one of the waste lifts. No problem. There isn't enough material in any one lift to kill anyone.

    Thus, a space elevator makes going 100% nuclear a viable option. Everybody has all the electricity they can use. Far less CO2 gets pumped into the atmosphere. You don't have to worry about storing the nuclear waste.

    Efficiency is the advantage. One of the new advances that has helped to miniaturize "wall-wart" type AC power supplies is they use a "chopper" transistor to chop the 60 Hz AC into a much higher frequency. That higher frequency AC can be run through a much smaller transformer to get the required voltage out of it, with less waste heat generated.

    NASA's funding has always been low.. Just because they have spent 250$ Billion up to this point does not mean it was a large waste of money. It took them several decades to rack up a tab like that. How long did it take the newest Bush Administration? Couple years? The only reason people (republicans) complain about it, is because they would rather of had that money for either war, oil exploration, or their pocketbook. If NASA had even 25% the funding of the American Military, we would already been living on, and exploring the surface of Mars.

    Back in 1993, I had just come through a period of being one of the most visible opponents of NASA's big programs and determined that political activism was a losing battle for technologists. That's when I wrote the following, "modest proposal" defense of big science programs [google.com] and which Griffin now admits were a big mistake:

    Subject: Who I am and why I support Big Science

    There have been some questions about who I am and what my positions are. Here are the relevant details for sci.space readers:

    As chairman of the Coalition for Science and Commerce [geocities.com], I have, over the last 5 or so years, been the principle activist promoting the Launch Services Purchase Act of 1990 and the launch voucher provision of the 1992 NASA authorization.

    To preempt some noise:

    Allen Sherzer has yet to apologize to me for his repeated slanders in this forum 2 years ago, declaring that my contributions to the passage of the LSPA were insignificant compared to those of Glenn Reynolds [slashdot.org], then chairman of the legislative committee of the National Space Society. However, during congressional hearings on space commercialization, the LSPA's sponsor, Congressman Packard, gave me a personal introduction (the only panelist out of over 10 to receive such an introduction) and my organization credit for passage of the LSPA. Congressman Packard did so with Glenn Reynolds sitting next to me on the same panel -- and he did not mention Glenn Reynolds or the NSS. This is in the Congressional Record and on video tape. Allen Sherzer's words are in the sci.space archives of late spring to early summer 1991. I encourage those with access to the sci.space archives to retrieve them and see exactly what Allen Sherzer said and the manner in which he said it.

    I've been involved in several other, as yet unsuccessful, legislative efforts to reform NASA, DoE (primarily fusion [geocities.com]), NSF and DARPA. In so doing I've come across gross inefficiencies in technology development -- inefficiencies that some small high technology startups were ready to fill with technical advances of great economic and social import. The government agencies I just mentioned see these high technology startups, not as vital partners, but as deadly political threats to the credibility of those, within the agencies, that picked incorrect technical directions. These government-funded individuals drive funding away from those who would bring us critically needed technical advances -- rather than working with and help them.

    The dollars we spend on NASA, DoE, DARPA and NSF to promote technology are actually used to suppress this country's technology in a frighteningly effective manner. But when one looks at the political incentives of these institutions, one wonders how anyone could believe it to be otherwise.

    My first and most tragic experience in this area was George Koopman's statement to me, made in person just before his untimely death, that NASA had been relentlessly driving his suppliers and investors away from doing business with his company, AMROC. NASA appeared to reverse its behavior in a tokenistic manner just prior to Koopman's death. The first test of an AMROC booster, shortly thereafter, failed and AMROC was forced into capitulation with established aerospace firms. This pattern of hostile behavior from NASA, combined with the means, motive and opportunity, leave room for reasonable suspicions of murder against individuals within or funded by NASA.

    The work they are doing right now in space is almost entirely peace-oriented, even if the science could easily be turned to make weapons.

    I'm not trying to troll here, but what kind of experiments are being done in space and how do they benefit us? Since the start of the space program, how have we benefitted aside from getting dried ice cream and Tang? It's nice to learn more about the environment we live in, but I can't think of anything offhand that has come out of space exploration other than learning about our surroundings, getting pretty pictures, or development of better materials that were driven by the desire to get into space.

    I'm sure there are many valuable things that we have learned as a result of being in space, but most people just don't know about them. Most average non-techies probably do not understand exactly why we're going into space so much - I'm even a nerd and I don't understand. Perhaps the public needs to be enlightened, and they'll be able to appreciate the space program.

    It's all tradeoffs. Linear supplies are also much lighter, at that frequency you can make the transformers very small. Filtering is easier because the ripple is high frequency.

    The tradeoff is that the transmission lines become more difficult. At 60hz you can run the power on nearly any old wire and it'll be fine. At 100khz the skin effect is stronger so fat wires to carry lots of amps don't work. You need special litz wires that have individually insulated strands.

    Interference isn't much of an issue, at 100khz the wavelength is 9,835 feet long. You won't get anything even near 1/4 wavelength long that could radiate a significant amount of power. For the same reason transmission line impedance isn't much of a thing to worry about.

    The original purpose of the Shuttle Fleet was not only small lifts and minor exploration. As everybody knows the shuttles carry a hughe main tank, which is dropped after burn out.

    The original plan was: take the main tank into orbit, move them into parking orbits, use them later for space stations and interplanetary vehicles.

    This was first reduced to: drop them on a parachute for refuling and reuse. And later it was reduced to: just drop them.

    If NASA did not had stepped back from the original path we now had about 111 empty main fuel tanks in orbit around earth. If you use 6 main tanks to produce one ISS like space station the shuttle starts would translate to 5 space stations with together 30 fuel tanks used. There would still be 80 fuel tanks left for building manned Lunar vehicles or a lunar orbiting station, or 2 Earth/Lunar L4/L5 stations, probably several manned Mars vehicles and unmanned Mars supplies vehicles.

    Landing some on the moon for having a starting base for a manned Lunar base would also be an option. Selling them to other nations with a space program, but not the resources to place "containers" in orbit would have been an option also.

    The Shuttle path was completely right, but it got stripped down more and more until only the shuttles itself where left. The reason behind that mainly are political, the cold war was over, no need anymore to to show presence or impress the enemy or to fund the "military industrial complex". In fact budget cuts where needed to use the resources elsewhere (but they did not get used wisely anyway, look at the education system e.g.).

    And now, we hear a NASA politician/bureaucrat making big words .... that stinks like politics again for me.

    Essentially the whole manned space program, in its current incarnation, is technical corporate welfare. Most (not all, but most) research could be conducted by robotic craft for cheaper. However, it is "manned spaceflight" that sells to the public (with the exception of a few high-profile robotic craft, such as the MERs), and allows space programs to get the money that they need for real science**.

    The question is, however: would it be better that money be thrown at shuttle/ISS, or some other manned program, and if so, what? If you think the cost overruns on a space station in LEO are high, wait till you see the cost overruns on a Mars mission. Did you like Apollo? In modern dollars, it cost an average of $13.5b/yr (NASA's current entire annual budget is $16.2b/yr). The space shuttle currently gets about $750m/yr spent on it, half of that is general and applied research (i.e., some applies only to the shuttle, some applies to rocketry in general), the other half operations, and even if you assume that the shuttle is *twice* as expensive to operate as other launch vehicles (an overestimate), you're looking at a surcharge to the public of under $200m-$600m/yr (depending on how much of the research money you count). Shuttle development, spread over its expected lifespan, totals about $1b/yr (also in modern dollars). As for ISS, it's about $3b/yr over its expected lifespan, although we don't pay that entire tab; also note that about half of the research that goes on in ISS is privately funded.

    Think a Mars mission will come this cheap when all is said and done? Not the slightest chance. It'll overrun worse than ISS. ISS overruns are largely due to things that we thought would be easy turning out to be much more difficult. Well, there is *far* more potential for that on a Mars mission, where you can't just pop up a resupply vehicle.

    If one cares about getting real science and technological advancements done, they should give the public what they want for as cheaply as possible. I think the CEV may be a good step in that; the Moon/Mars mission isn't, really, although it does make a nice inspiring thing to tell your grandchildren about. ;)

    For anyone curious about where NASA plans to spend their money, this [cbo.gov] page has some interesting charts.

    ** - There are important things that are developed by the manned programs, to be sure - in fact, these often tend to have the most direct impacts here on earth (simple, portable medical equipment; water treatment; etc). Also, technologies that do eventually allow a long-term human presence in space at affordable prices will take a lot of pratice to get right - look at how difficult it's been to make a long-term usable water electrolysis system that works in space, for example (and "refining" processes don't get much easier than water electrolysis - just wait until we try all of the steps needed to produce, say, aluminum offworld). In general, however, as far as gathering knowledge goes, robotic craft are far, far more cost efficient.

Suggest you just sit there and wait till life gets easier.
