The Technological Stagnation of Human Culture
The below article is the synthesis of two articles on which I have been writing simultaneously. I put them together in order to hint at the recent historical context of the forthcoming retirement of the Space Shuttle. To begin with, I would like to make clear that when I talk about technological stagnation, will be referring myself to what I define as macroscopic engineering, or macroengineering for short. Macroengineering is not electrical engineering. Nor is it nanoscopic nor bioengineering, since the latter is based on genes. Macroengineering can be defined as classical engineering, since it exists at least since Roman times. And with a few exeptions like the Large Hadron Collider (LHC) at CERN, today it clearly is aerospace engineering which harbours the greatest developmental challenges of all branches of macroengineering. And in aerospace technology, it naturally is the transporation of people which places the highest technological demands. As a consequence, this is also the potentially most expensive of all branches of engineering. And in terms of a philosophical sidenote, machines can well be considered as the most astonishing product of terrestrial life. Together with ideology and economy, machines are one of the three major forces shaping cultural evolution. Possibly only a few of you will be aware of what kind of twentieth anniversary we have had yesterday: On the 15th of November 1988 ocurred the first and only orbital flight of the Soviet Space Shuttle Buran. The Buran was in some ways a more advanced spacecraft than the American Shuttle. It could carry 20% more cargo than the American shuttle, it´s orbital maneuvering system was much more potent and it´s only flight of two orbits was unmanned, i.e. it was fully automated. The most beautiful images of Buran which I found on the internet are at http://englishrussia.com/?p=1362 . The last photo, or third image from the bottom, of that page clearly shows that the main engines of the shuttle did not participate in the launch. The most tragical aspect about the history of Buran is the manner of how it ended. After the Buran program was stopped by Boris Yeltsin in 1992, the orbiter was mounted - horizontally, as is usual in Russia and was in the Soviet Union - on top of a fully assembled Energia rocket inside building 112 at Baikonur, so that the whole launch configuration could be seen by visitors. After the dissolution of the Soviet Union, Kasachstan became the owner of the Baikonur cosmodrome and all of its contents, including the Buran. But Kasachstan had no interest at all in the shuttle, so there was no money for the maintaineance of building 112. And on the 12th of May 2002 the roof of the building colapsed, completely crushing the shuttle below it and killing the 8 workers, which had finally arrived to work on its roof. So by then, it took no more than the weight of these 8 workers to collapse the roof. And as you can see at 45º55´41"N 63º17´52"E on Google Earth, this roof has remained unrepaired up to the present. The sad result of this incident can be seen on the page http://www.buran.fr/bourane-buran/bourane-fin.php . For me, the most depressing among these images is "hangar11-grand". The Buran project was stopped at a time when Russia was plagued by financial problems.. I have not found any information which could reveal whether it´s demise might have been due solely to the lack of capital, or also due to the lack of appreciation and the resulting will to somehow keep the project alive. At any rate, the Buran project was as costly as was to be expected: Between 14.5 and 20 billion Rubles, as estimated on page http://www.aerospaceweb.org/question...ft/q0153.shtml .. The Soviet Union saw above all a military threat in the American Space Shuttle, so the construction of Buran was primarily motivated by trying to counter that threat. With the dissolution of the Soviet Union, this primary motivation was also gone. Nonwithstanding, the demise of this exellent piece of engineering was a sign for the times to come. As the next great technological loss after Buran I would consider the Lockheed SR-71, which had its last flight on October 9th 1999. It was a military aircraft, but it was unarmed. This is significant because today - and in distinction to manned spaceflight - arms must be considered as culturally counterproductive "achievements" of our species. And even though, according to Wikipedia, the SR-71 had only 23% of the enormous range of 23,400km of the Global Hawk, it could outrun rockets (Mach 3.2+ vs. 650km/h for the Global Hawk) and flew 30% higher than the Global Hawk (25,900m). And it had stealth properties. As always, the price tag played a role in it´s demise. But in this case personal motives and a lack of attitude were causes so obvious, that I can hardly add anything to this subject here. Instead, I invite you to read what is said on the page at http://www.area51zone.com/aircraft/sr71.shtml about this issue. After that, the next great loss was surely that of the Concorde, which had one fatal accident in its 27 years of service on the 25th of July 2000, and which had its last flight on the 22nd of October 2003. Due to the sonic boom issue, the Concorde had ended up as a medium range (max. 7,250km) trans-oceanic airplane, which is sort of a contradiction in terms. It could not reach South America from London, and thus became a single route airplane between London/Paris and New York. Nevertheless, it was ludicrous that British Airways refused to let Richard Branson of Virgin Atlantic Airways buy a few planes with the argument, that only British Airways and Air France could service that plane. But the definitive knockout for the Concorde came, when for yet unknown reasons Airbus started to demand exorbitant prices for Concorde spare parts, and there are persistent rumors that this was due to a secret arrangement between Air France and Airbus (see http://en.wikipedia.org/wiki/Concorde). Even though there were times when the Concorde, just like it happens to any other passenger airplane, flew only half full, during its last months it was completely booked out, and there were plenty of people who were sad and angry about it´s demise (see http://query.nytimes.com/gst/fullpag...agewanted=all). The Concorde offered the unique educational experience of letting its passengers see the roundness of Earth and the blackness of space. What I have searched but never found, is the reason of why charter flights on the Concorde stopped after the July 2000 accident. Had Richard Branson been able to make the deal with British Airways, who knows: Pehaps there would have been Concorde flights between London and Rio de Jainero or even Buenos Aires with a refuelling stop on Santiago Island (Cape Verde archipelago), or perhaps even between Los Angeles and Sidney with a refuelling stop on Kirimati Island (Line Islands, Republic of Kiribati). These lonely and poor island republics would quite likely have been happy to have the Concorde put them on the map. But never mind - I´m just dreaming about what could have been, because somebody ought to. So should Richard Branson and his aerospace designer Burt Rutan be able to pull off their project of the suborbital passenger vehicle SpaceShip Two, they will deserve a monument simply for going against the trend of our time. Supposedly, SpaceShip Two will fly next year for the first time. But the unbelievable thing is that they say that if SpaceShip Two will be a success, then they will plan on a SpaceShip Three which would be orbital (see http://www.flightglobal.com/articles...succeeds.html). I tend to doubt this. But if it should happen, then it will be a tremendous slap in the face of NASA. Because what I would consider as the greatest technological loss since the fall of the Roman Empire is going to come soon, in 2010: The retirement of the U.S. Space Shuttle. The claim that the Shuttle is a principally flawed system, is basically the same as claiming that the external tank (ET) can only be built just the way it is, with just this length and just this foam covering it outside. This claim is daring, to say the least, and I have yet to see some argument which would prove it. As far as the Challenger accident is concerned, I think it can be blamed on the "space or bust" attitude of NASA, when it inicially tried to change it´s image into some sort of space trucking company. In distinction to the Columbia accident though (bubbles in foam), The Challenger accident did not have a single cause, but came about through a combination of causes (see http://www.aerospaceweb.org/question...s/q0122.shtml). Nonetheless, I wonder why NASA never put some electric heating collars around the seams between the solid fuel rocket booster (SRB) segments, which would fall off just before launch. Next to every idiot should be able to design a simple, cheap and failproof system for that purpose. The claim that an outer, tear resistant coating would introduce the danger of even larger pieces coming off and damaging the Shuttle´s heat shield, ignores the proposition that this coating is supposed to be tear resistent in the first hand. This would of course add weight to the Shuttle. But there is no reason to assume that a somewhat longer tank containing somewhat more propellant to compensate for the added weight would worsen the aerodynamic properties of the Shuttle´s launch configuration. Intuitively speaking, a somewhat more stretched launch configuration should rather have better aerodynamic properties than a more stubby one. And a polished coating should improve laminar airflow (less air resistance) on the outside of the tank in comparison to the rougher foam surface. And since the ET tends to deform itself slightly during flight, a more rigid outer shell might actually help here. And is the foam today employed really the only substance, which could possibly serve the function of thermally isolating the liquid hydrogen and oxygen tanks? As it turns out, during launch this foam is not loosening itself from the tank, but it is internally desintegrating, largely due to enclosed air bubbles expanding. The "solution" to this problem which NASA and Norton Thiokol have come up with, is as usual the cheapest one possible: They just spray on the foam more carefully, hoping to avoid the formation of bubbles. I´d really like to get my hands on a piece of this cursed foam, and I wouldn´t be surprised, if I could sink my fingernail into it. Now if this foam is not replaced by anything else, then the above mentioned tear resistant outer coating of the ET would need to have venting holes of the appropriate diameter and the appropriate spacing, so the air released by the foam can escape. And once one starts to contemplate the possibility of a longer ET, why not also contemplate the possibility of non-cruogenic fuels, which would have a lower specific impulse but don´t need to be isolated? Never mind, I´m just wondering because somebody should. Now, to say that the development and testing of such implements would take too much time since the Shuttle is supposed to go out of service in 2010, is nothing but saying that improving the Shuttle is impossible because NASA has decided that so it is. Rather cynical, if you ask me. Another problem is, that nowadays there exist plenty of people who believe that, regardless of its size, a manned space vehicle should be built to be 100% safe. But first of all, exploration includes but is not the same as investigation, and it *implies* putting one´s life at risk. Amundsen and Scott would agree with this. And second, there is not even a commercial airplane in which all passengers have ejection seats. Furthermore, the concept of cheap access to space (or CATS) was not only based on the cheap and quick turnover of the Shuttles between flights, but also on a hoped for synergy between the Shuttle and the International Space Station (ISS). The idea was that lab research on the ISS could develop valuable products like alloys, crystals, perfect ball bearings, etc., which could only be produced in space in order to then be sold on Earth. It was seen as a first step towards not just CATS, but towards an at least in part economically self sustained human presence in space. Or in other words, CATS or no CATS, it is principally impossible to develop an economically sustained human presence in space without a vehicle which can return freight to Earth. So if the Shuttle were too unsafe to transport people, then it would be necessary to develop an unmanned vehicle which can transport a good amount (more than a dozen tons, say) of freight from low earth orbit (LOE) back to Earth. The Soviet Buran Shuttle could in fact fly fully automatic from start to landing, and in the first missions it was planned have a Soyuz dock with the Shuttle in orbit and the crew entering and leaving it before the Shuttle returns to Earth. But this procedure would of course require the maintaineance of two rather sophisticated trans atmospheric transport systems which can both return to Earth and which would often need to cooperate for the same missions, one for freight and one for crew transport, which would supposedly be even more expensive than a Shuttle which can transport both freight and crew. Unfortunately, the microgravity on the ISS turned out to be a major obstacle for the straightforward development of plans to develop valuable space products to be sold on Earth, such that there would have been extensive research necessary to overcome these problems. But due to the failure of ESA to develop the Hermes rescue vehicle, the ISS could never be manned by more than three people, with two being the minimum for the maintaineance of the station. Considering the tremendous amounts of experiments that are mounted in the ISS, it´s poor production of scientific papers, which you can see at http://www.nasa.gov/mission_pages/st...lications.html , can only be explained by the cronical lack of personell. Now NASA will prepare the ISS for a crew of six, even though the first manned Orion capsule is not scheduled to arrive before 2016. But by then it will be far too late. What appears to have been forgotten, is that the specialty of the Shuttle is not to bring payloads into orbit, but to bring them back to earth or servive them "at the roadside" in LOE, in fact converting LOE into a roadside of sorts where you can leave, pick up and exchange anything you like within the payload capacity of the vehicle. Without the Shuttle, the Multi-Purpose Logistics Modules (MPLMs) on the ISS will basically loose their intended function, since it will not be possible any more to return them to earth, and thus there will be no more exchange of experiment racks. So once you get six people to work in the ISS, it would amount to a fourfould increase of the personell available to do productive research work - two being occupied with station maintaineace - at a time when the exchange of experiment racks will be no more possible. And anyone familiar with labwork will know, that in order to obtain a desired result you often have to tinker around modifying your lab setup. Especially if you want to obtain a new material. Due to the unavailability of research supply outlets on the ISS, there is very little margin for tinkering in orbit. This can only be done on Earth, and this is one of the reasons why without the possibility of an efficient exchange of experiment racks by means of MPLMs the ISS would soon become overstaffed, rather then understaffed as it is right now. And without the Shuttle there will be nothing which can exchange MPLMs. In summary, that hoped for synergy between the Shuttle and the ISS mentioned above never had a chance to develop, and in all likelyhood will never have a chance to develop in the future either. I am certain that there exists at least one simple explanation of why NASA has never managed to improve the ET: The ever present lack of funds. I was already becoming suspicious that something was wrong, when more and more time passed without the Challenger being replaced or new versions of the Shuttle being built. So the fleet just started to age. Supposedly seduced by the Apollo success, for a few years I also believed in that delusion of instant CATS thanks to the Space Shuttle, but I did finally recognize how naive I was then and that I had just fallen for a propaganda trick of NASA. In fact, today I feel that most of NASA´s claims are nothing but propaganda based on hot air (NASA going to Mars? What a joke! I even have doubts that they´ll make it back to the moon. Doesn´t matter if we´ve already been there or not). So now they are trying to build some sort of Apollo-on-steriods (Orion), with a launch vehicle (Ares I) partially derived from the Shuttle SRBs and apparently designed primarily for being cheap - with the consequence that as of right now it threatens to be incapable of carrying the capsule into orbit (see http://www.orlandosentinel.com/news/...0,561055.story or http://www.nasaspaceflight.com/news/constellation). Due to their relative simplicity, solid fuel rockets are much cheaper than liquid fuel rockets. Basically, they mean "more bang for the buck". And what am I to think about that idea of accelerating the Orion capsule backwards when injecting the craft into its lunar transit trajectory, so its crew gets pulled out of their seats? This sometimes makes me wonder about whether in reality the lunar option of the Constellation Program might not just be yet another promotional trick of NASA. It is ridiculous to believe that these small Orion capsules, - designed as of right now for six people and next to nothing else - which represent a radical reduction in technological complexity in comparison to the Shuttle, will somehow be able to replace it. Nonetheless, NASA keeps insisting on trying to sell dreams on a shoestring budget, among other things because "defence" spending always comes first on the government agenda. But a protesting NASA director soon will be an ex NASA director, and thus he/she is obliged to keep the mouth shut and just keep selling inspiring propaganda lies. The major question here to which I cannot find an answer, is: How can the development of the Constellation Program, which does in fact appear to be flawed already now, possibly be cheaper than the development of a new ET for the Shuttle? But besides that, I am moved by a really harrowing question: Quoting from "An Analysis of NASA´s Plans for Continuing Human Spaceflight After Retiring the Space Shuttle" published this month by Congress, it says "In 2004, President Bush announced his “Vision for U.S. Space Exploration",...” and " The President also directed NASA to develop new vehicles for human spaceflight that would allow missions to the moon, Mars, and beyond." (see http://www.cbo.gov/ftpdocs/98xx/doc9...SA_Letter.pdf). And I wonder: Did this "vision" really originate in the feeble mind of that simpleton, or did he consult with NASA specialists before trumpeting it out? Because if he didn´t, then this would explain everything: If he did not consult with NASA specialists before getting that idea, then NASA has simply fallen victim to a patriotic knee jerk reflex in the simple mind of a president - for whom national pride naturally counts far more than lofty goals for humankind - when he heard about the Chinese aiming at the Moon. If not, then the now almost forseeable failure of our species to permanently establish itself in space would turn out to be the most nefarious legacy of that quasi chimpanzee (human beings are never born, but made by education). Because at NASA, the seat for a chimpanzee better be in a test capsule, but not in the director´s office. Just like was the Apollo program, the Shenzhou program is basically motivated by national pride, even though the future docking adapter on top of the orbital module of Shenzhou will be identical to that of the Soyuz, so that Shenzhou will be able to dock to the ISS. Can a NASA director say "no", if the president comes up with a stupid idea? As far as I can see, the Constellation Program is equivalent to giving up on the vision of establishing terrestrial life beyond Earth´s atmosphere, in exchange for doubtful promises of space adventures. And there is nothing about the Constellation Program which bears direct relation with a mission to Mars. The financial restraints are for real, but so is a lack of attitude. And not so much on the side of NASA, which is just a government agency obliged by the circumstances to make false promises, but on the side of the people who vote for that government. Most people don´t have the slightest interest in that our species learns to establish itself in space. In fact, there are plenty of people who for whatever reason would be happy to see manned spaceflight be stopped altogether. And I do believe that this could really happen to us, even though I hope that I will not live to see it. It is naive to think that the spirit of the explorer ("Go where nobody has gone before..." etc.) is somehow innate to Homo Sapiens. Some cultures explore, and others don´t. One only needs to recall the enormous fleets of giant ships which the Chinese sent all the way to Africa in the early 15th century, only to stop next to all maritime travel just 50 years later. The cause seems to have been a major swing in government philosophy (Conficianism) towards isolationism in the late Ming period. I believe that a study of this episode of Chinese history could teach us a lot about what could happen to ourselves in the near future. Another illustrative example are the the aborigenes of the Canary Islands (Spanish territory off the west coast of Morocco). Among these seven islands and measured from La Gomera, Tenerife is at a distance of only 28km, while La Palma is at a distance of only 57km. All of these islands were habitated by aborigenes and are full of timber, yet none of these aborigenes ever built boats. There exist other minor contemporary signs of a cultural trend towards technological stagnation in macroengineerig, which are not as spectacular as the cases mentioned above in this article. For example, the FIA has now decided that in the future all Formula 1 cars shall race with the same motor. And Ferrari has announced, that in this case they will leave the F1 circuit (see http://www.formula1.com/news/headlin.../10/8595.html). F1 cars are already now subject to severe technological reglementation, and I applaude this decision by Ferrari. So if the FIA sticks to its decision, then I hope that Ferrari will do so as well. And they should do so with their head held up high and a parting statement like:"May the proponents of technological degeneration compete among themselves on the racetrack, Ferrari is not and will not be among them". Anyhow, piston engines get me bored, and I guess I would only watch car races if the cars were powered by turboshaft engines. I could give more examples of stagnation tendencies in macroengineering, but what would interest me is if the reader could provide me with counter examples of significant qualitative contemporary advances in macroengineering exept for arms development, like the LHC which I mentioned at the beginning of this article. What this all boils down to, is that it most likely is not the concept of a Space Shuttle, which is inherently flawed. But instead it´s our species which, as a logical consequence of evolution, is inherently flawed - and by far not only because of the technological issues discussed above. But this is not an appropriate forum for a general discussion of human cognition and postmodern attitudes. Peter Holm |
