  1. more coverage on Armstrong, Cernan Testify Against Obama Space Plan · · Score: 0, Flamebait

    Will Obama's "Commercial" Human Space Program Need a Bail-out Bigger than GM?

    May 13, 2010 (LPAC)—As the Congress is forced to try to rally itself to make decisions on the future of human spaceflight, Apollo 17 Commander Gene Cernan told members of the Senate Committee on Commerce Tuesday afternoon, that NASA, itself, has little confidence that the crazy plan to have private companies ferrying American astronauts to low Earth orbit, will succeed.

    Cernan and Apollo 11 Commander Neil Armstrong, who also testified, were briefed, for two hours last week, by NASA Administrator Charles Bolden on the Administration's "plan" to kill NASA's Constellation program. Cernan said that Bolden expressed his concern that the private companies "might have to be subsidized" by NASA until they succeed. According to Cernan's account, which he said was based on notes he took during the conversation, Bolden said it "may be a bail-out like GM or Chrysler — it may be the largest bail-out of all time," when the companies run into difficulties and out of money.

    Cernan said that, based on his own experience, the program for private enterprises to safely launch astronauts into space within five years, and more cheaply than NASA can do, will, in fact take a decade, and cost two to three times as much as they predict." He told the Committee that there will be "unplanned delays, costing unallocated billions of dollars." He cited a study by the Aerospace Corporation, which projected that it would cost $10-12 billion, not the $6 billion the White House is allocating, to develop, test, and fly a new crew vehicle. And these costs do not include the necessary infrastructure, Cernan explained, including simulators to train the crew, changes needed to Mission Control in Houston, or the ships and command for sea-based rescue required for the returning craft.

    His recommendation: stretch out and add to the Shuttle flights, to close the gap "on the front end," and "knock three, four, five years" off developing Orion, to close the gap from the "back end." Neil Armstrong added that he saw no reason not to continue to fly the Shuttle, and that since the design for Constellation was optimized for safety, the Constellation vehicles should be completed. Neither astronaut saw any value in Obama's offer to develop an "Orion lite" version, that would be taken to the station unmanned and just used for emergency escape. The Russians already provide that very well, with the Soyuz, they both pointed out.

    Leaving aside embarrassingly idiotic queries from chairman Rockefeller (D-WV), and lies and obfuscation by greenie "science" advisor John Holdren, there was no defense of, but much skepticism concerning, wrecking the nation's manned exploration program.

    from astar: It is fun that Holdren appears in the climategate emails urging on Jones that everyone must be "true believers" in global warming. No one wants to say any more that Jones is an attractive sort. But it is interesting to think he might have once been in fact, as opposed to perception, respectable. And then you think about what happened and you consider what politicians (oops, respectable scientists) like Holdren might have done to his environment in the past. And now you get to see something similar going on with respect to NASA maybe. And even some of the same players.

    shelf life is a good point

    If you want to consider software that is immeadiately vital, you would look first at software that was directly embedded in the physical production process. Just looking at current popular concerns that match this, consider electrical utilities and freight transportation.

    If you are looking at electrical utilities, you see 50 year old software, which is pretty good for a shelf life.

    On the other hand, in a sensible society, you produce a lot of machine tools, and you make lots of continuous improvements. So the shelf life of the controlling software is real short. And putting a government critical path component in gives me lots of warm fuzzies (NOT).

    So I guess you could play programmer licensing games and so on. So we might know more than we did about programming than 50 years ago, but if you eliminate all the current fads, what do we really know and how often do we really apply it? So what body of knowledge do you base compentcy (spell) for licensing upon?

    acm sometimes has occasion to make official statements on licensing issues. For some reason texas get this in their head every once in a while.

    I suppose I should mention that proveability approaches get a little further along over time. I recall that somebody recently managed to prove a microkernel. At the present time, I suppose we could talk about some sort of proven components to use when possible, maybe government generated. But last I looked you almost had to have special languages.

    Impossible is a funny word. The classical electron is impossible (how could you possibly explain that dense a charge), but people did not make a big deal about it.

    So here a few uncited rememberances

    Some people saw some ball lighting go into a barrel of water and boil it all, completely as I recall. This gives a number for energy and it is much too high for a simple explanation.

    So the problem is there is too much electrical charge in too little volume. Sound familiar?

    I thought it was all cleared up decades ago with some sort of dynamic vortex theory.

    Personal story: from a reliable adult when i was in high school. A lightning storm. A big hit on a tree near some utility lines near the adults home. At a coincident time, claim of some ball lightning showing up on the kitchen counter, perhaps associated with telephone wiring and equipment. It moved down the counter and disappeared in the wall. A charred area was pointed out. So I suppose this was almost 50 years ago. The adult is gone. I assume the char spot is gone. So maybe you have hundreds of years of such reports. And we have thousands of years of religious oriented reports of miracles. It is fun to try sorting out the difference. Probably, it is silly to assign some uniform true/false value to all the reports in either example.

    I will take a shot at it.

    First of all, there is the interesting question of quantification. I have seen some predictions that start with the CO2 stuff and come up with a lag time of what, 600 years. science does not have to be quantified by any means, but none of your points are very interesting without some verified numbers. overwhelming natural processes is a bit interesting, but it is not that anyone can really claim that natural processes should dominate. Now I do like the acidification of the ocean claim.

    but being a bit nasty, I might make a nice physical claim that increased insolation would allow me to predict a nicely corresponding global temperature increase. but, since insolation seems to have increased 25% over the past, very long, period without an obvious death of the biosphere, maybe i am missing something somewhere. Now it seems the awg computer models change whatever it is that think of as their physical basis rather often, if i feel emperical, I guess I would say the models are going to continue changing their code significantly. but plug in long term isolation and tell me what the awg models say. my, such settled science.

    so i am probably narrow. I really think of an interesting model as a set of partial differential equations. nice physical basis. and i have not done that stuff for a long time. but i sometimes see comments on slashdot from people who sound like they might really know something about reliable modeling of physical processes and they did not seem very impressed with the awg types.

    on models, I recently saw something about a problem with duplicating the cosmic background radiation models. I do not recall any claims of hiding the basis of the models or hiding the data and i bet it is all very physical, but you go from having a signal to not having a signal. computer models are maybe only maybe 60-70 years old. sort of science, and sort of math, but probably not science in the way Jones wants to think. You can phrase an aspect of the problem in an interesting way: did a computer model ever yield a new fundamental principle of the universe?

    this area is called administrative law. It is supposed to be simple, informal, and navigateable without a lawyer :-)

    the reason it is constitutional is that while you have go into the admin court system, when you exhaust your remedies, you get to go to the usual courts in the other branch of government.

    as far as rules, agencies can make all sorts of binding rules, persumedly from within their enabling language. and all the admin judges will take them as gospel. but once you leave the admin system, the other judges will feel quite free to slap the agency around.

    Actually, having rules is a positive. I have seen programs repeatedly try to run without any rules! for the admin review judge, a question becomes "do i shut this program down". Interesting considerations at that point.
