    The Washington Post reported Thursday, however, that two officials overseeing health and environmental conditions on the space station didn't sign off on the launch, instead signing a dissent that warned about ``the continued degradation'' of the environmental monitoring and health maintenance systems and exercise equipment vital to the astronauts' well being.

    Shouldnt these people _have_ to agree that it's safe in order for it to keep operating? They, after all, are the "officials overseeing health and environmental conditions". Who has to say 'yes' or 'no' and have it mean something?

    There is believed to be tension within NASA between safety experts who fear the ISS is becoming dangerously dilapidated and astronauts and managers who do not want to leave the outpost unmanned for fear it could become vulnerable to an accident that would make it spiral out of control.

    Space travel is generally acknowledged to be risky. The astronauts are certainly aware of this. NASA should do all they can to repair the ISS, but it makes no sense to jettison a project that cost tens of billions of dollars (not to mention millions of man-hours) simply because the risk levels have increased.

The ISS has never lived up to the research potential promised when it was sold to the taxpayers.

    *Any* complex machinery/construction/whatever is going to need maintenance over time. What I find irritating isn't so much that NASA thinks pieces need to be replaced, but the public's reaction to such news. "What?!? You want more of my money to *repair* the darn thing before it is done being built?"

    Just because it is in space things doesn't mean things won't wear out. This isn't the Star Trek Universe.

    Although, it should be interesting to see how the need for maintenance will affect the development of the spacestation. Sometimes it seems like it was projected based purely on a "best-case" scenario (ie, everything works right the first time and works right until all the work is done).

    I'd like to see how this impacts projected missions to the ISS... if they don't step up the number (of missions), will this lead to an escalating decay in productivity (ie, every flight will be just to bring repair parts for what has been built already?).

    1. Something gets designed and deployed
    2. For each time interval from initial design to infinity, some engineer is complaining that it's not safe enough and that a more expensive solution or complete redesign is necessary.
    3. For each complaint, managers, who are not technically illiterate, but not as "into it" as the engineers, need to evaluate risk based on imperfect information.
    4. Usually, system robustness and other factors dominate. the system is just fine. the engineer's complaints fade into obscurity, even though "deep down" the engineer knows he was right.
    5. But, occasionally, something goes wrong. Instantly, the managers become know-nothing literature-major innumerate MBAs. The engineer who picked the "winning" flaw gains fame.
    6. Therefore, claiming that something will go wrong with the ISS is a good way as any to win the lottery.
    7. The problem MUST be that managers are unschooled in dynamic systems theory, right? Because they don't understand complexity, probability, and risk---right?
    8. But wait, that's wrong! Today's managers ARE trained in those things - i mean, that is the very basis of being a technical manager today! what's the problem then?
    9. could it be that the engineers are trained in engineering and don't know how to effectively communicate and QUANTIFY their risk assessments? nobody at /. will agree to this, but imho, that view is easily at least half right.

    Well the ISS is more than just 3 years old, its only been in space for 3 years but parts of it where designed and built as far back as the later Regan early Bush years (that Sr. not Dubua) I know cause the guy who designed the superstructure for the solar arrays (and inccidentally enough the building to construct that superstructure since it was test fitted on earth and thus needed a huge building to support it) graduated from our tech department in 1989 and almost imediately started working on the Hubble and then manage the 3 or 4th team to design the final ISS design based on some of the stuff they had built and tested for Alpha (the superstructor is actually newer than the moduals)

    Anyway, the other thing you have to remeber is that in relation to the Russians with whom safety was a concern but not as much so as we cared about, the Mir was a deathtrap in our minds. I remeber after the remote probe incident all of the NASA officials talking about had it been us we would have crash burned the thing years ago. So in relation to the Mir ours might be in great shape, but after Columbia they dont want to take any chances.

    Personally, I suspect it will-and the ramifications to the US power structure will be tremendous. The US elites expend a lot of energy to maintain the image that the US is _the_ technological superpower. Problem is, the US government isn't run by men like Franklin and Jefferson any more(guys that got fame by being scientists/inventors)-the congress today is composed almost entirely of a bunch of lying weasels that spend much of their time begging for money from corporate oligarchs and planning their eventual "cash out".

    So can China beat the US in space? At this point, I suspect it can. The US elites are so rapicous they can't provide technical incentives to maintain the present industries in the US without liquidating resources-let alone build new space industries.

    Besides, folks like Bush/Clinton are both kept in office by a steady stream of credit from China and other far eastern countries. Sooner or later that will come to an end. The Chinese leaders strike me as much more cagey than the old Soviet elites-they won't make a really big splash until they think it is too late for the US elites to do anything about it.

    Pretty simple, I'd guess. Look up any information on MIG-25 development. Shortages of titanium led them to basically rivet the thing together out of steel plates; the air-to-air radar was powered by a bunch of massive vacuum tubes.

    Remember the story of how the US spent $5 million to develop a space pen, which would work in vacuum, under water, in massive heat, etc? (The Fisher space pen, I have one, they're pretty nifty)

    ...like the various X-Prize teams.


    If a NASA shuttle blows up, they just have a public enquiry. If an X-Prize rocket blows up, the team loses all their bragging rights. Hey, that's a lot of incentive.


    For those who've followed my previous posts on space travel, I have always contended that amateur and semi-professional ventures will ALWAYS out-pace both the commercial and Government sectors.


    This is what we're seeing. The ESA, the Russians and the Chinese are mostly into commercial space work. The ESA is only just about at the moon, and there's no evidence any of them are interested in going further. This after two decades of effort by all concerned.


    At the Government/National/International level, everything is either dead, dying or very likely to start dying in the near future. This, after over three decades of effort by all concerned.


    The X-Prize contestents have not seriously been working on any large-scale rocketry, with the exception of the Australian OzRoc team. The UK's Starchaser group looks promising, but until they started into the X-Prize, they were not doing much beyond high-altitude rocketry for photography and other basic commercial work.


    The serious amateur work has been done in the past three to four years. In that time, amateurs have gone from sending up cameras to being within a year of sending 3-man crews into space. The Chinese only managed a single man crew, in decades of work at space research.


    I really and truly believe that by 2100, the aerospace engineers working -on- Mars will be the philosophical descendents of people like Richard Stallman, Linus Torvalds and Alan Cox.


    Those working on putting pop-up ads into Mars orbit will be the commercial sector. (Apart from those putting pop-up ads into Earth orbit.)


    Those working on a white paper speculating on the number of votes the last accident cost the President or Prime Minister will be employed by the Government.


    The bottom line is this. Rocks in space aren't on the electoral register and don't have money to spend. Until someone gets there first and creates a reason for others to follow, they won't. This has always been true in exploration. Geeks Lead, Leaders Follow.

  18. NASA didn't have a choice by igny · · Score: 3, Interesting

    Besides the prime crew (M. Foale, A.Yu. Kaleri, P. Duque) there was a backup crew (W. McArthur, V.I. Tokarev, A. Kuipers) of the Soyuz TMA-3 ship. If, for any reason, NASA backed out, but Russians (and probably ESA) did not share the same concerns, they would have sent Tokarev instead of Foale. For the first time ever, the ISS team would have been %100 Russians, thanks to whistle-blowers in NASA. Then the American Public asked NASA "Ahem, did you just spend some $30bln+, and then backed out, giving the way to Russians?" And then what? Will NASA just write off ISS, and let other nations use it? Or NASA will sabotage any such use, possibly by disassembling or destroying american parts of ISS or making them uninhabitable or otherwise offlimit to visitors? I know that is ridiculous, but so are any demands to abandon the project.

    For your information. Russians can build Energias, which is a monstrous rocket booster capable to lift huge fully automated cargo vessels. In contrast to american shuttles, Buran, the russian shuttle, did not have to use engines for the lift off, all the heavylifting work was done by Energia. Buran's engines were used primarily for maneuvering on orbit and deorbiting. Its only flight has been fully automated. That would have been an ideal tool to bring pieces of ISS up there. In fact Russians proposed use of Energia/Buran for ISS construction, but NASA, of course rejected the plan. Russians did not have enough money, and NASA wanted to sponsor its own technologies, and use american labor. It cost a lot more, but helped Boeing, other NASA's contractors, and, probably, american economy in general. More was spent, but more was spent in US, not in Russia.

    Of course, despite evident capabilities of Russians, they are not able to build or to use ISS without NASA, even with cooperation with Europeans and Japanese and Chinese. Not yet anyway.
