Yes manned programs are more expensive, but when conducted properly they can return vast quanities of Science. Apollo and Skylab were very effective, Shuttle and ISS are a waste. I wonder if you'd say the same if Skylab had to carry the full development cost of the Saturn V and Apollo spacecraft rather than being a tag-along. It worked on the Moon between 1969-1972, detailed science was done with manned missions and no one died there. This was as much a matter of luck as design. History shows that nearly every single Apollo lunar mission had at least one, if not more, significant problems that could have lead to loss of mission if not loss of crew. There are whole classes of failures that kill robot missions dead which would take a manned crew 30 seconds to resolve and move on. Yet, putting a crew onboard introduces orders of magnitude *more* classes of failures, and not all resolvable in 30 seconds, if at all. All the technology was in place for a long term science and exploration program on the moon in 1972, we let the capability drift away, but the technology and much much more is available Sorry, the capability we had in 1972 was vastly *unsuitable* for a long term program of that sort. Maybe after another 20 flights and some serious debugging of the hardware. Maybe.

The only thing Bush added that NASA hasn't had goals for all along was the
retiring of the Space Shuttle. Big heads at NASA talked of retiring the shuttle but that can't really be done until someone higher up gives the go ahead. All the other stuff was already NASA's goals. "quibbler" wrote in message ... In article 0Y1Qb.235603$ts4.56758@pd7tw3no, says... The media and this group should stop calling the new NASA directive a 'moon plan'. It seems that the belief is that Bush is cancelling everything NASA does and moving all the money into a manned moon base. This isn't the case at all. No, that is quite the case. You're just in the early stages of denial and haven't faced budget realities. The fact is that Bush has demanded a wasteful realignment of NASA resources toward a manned mission which will be ruinously expensive. The fact is that real science is far to expensive with a manned program. Robots must lead the way. It would be more accurate to call this an 'exploration plan'. No it wouldn't you republican shill. We can explore without manned missions or a permanent moon base. Bush is destroying the real science programs because he just doesn't get it. "Exploration" is just a bull**** buzzword. You apparently weren't smart enough to figure that out, so I'm afraid I've got to break it to you bluntly. The Bush administration only wants diversionary stunts. They don't give a rat's ass about science. They are theocratic cretins who know that if we do eventually find evidence of past life on mars that it will be devatating to their religious world view. What's really happening is that NASA's focus is changing from LEO cargo flights and ISS That focus was instituted under the moronic Reagan adminstration. They demanded "space station freedom" to keep up with the Ruskies. Bush happily continued that program and even vowed to keep flying the shuttles in the aftermath of columbia. maintenance, and towards more exploration and science. Bull****. We do science and exploration with unmanned probes. Period. It would be inordinately dangerous with present technology to do any kind of detailed science with manned missions. Instead of a robot like spirit failing, our whole crew would die. People are too fragile to explore most places. Even if we sent men to mars we would probably use them to drive robots around remotely in real time. What we need to do is invest in research and develop our technology. It's obvious that our present technology is not quite up to the task of serious "exploration" as it is. Relying upon it for a manned program is crazy. It's not even clear at this point that the main focus will be a moon base - that was just the hook for the public. What a ridiculous excuse. A politician directly states something as policy and you're so in thrall to your right wing ideology that you now say, "That's not what he really meant. That's just what he was telling the plebes". If that was his idea of PR then it backfired bigtime. Most people thought that a manned return to the moon would be a hugely wasteful stunt. Now the Bushies are spinning like mad trying to back pedal and soft pedal and do damage control. NASA has distributed its Vision under the new initiative to its employees. Here's what it says: That's nice. But the idiot emperor Bush has demonstrated that he's gonna micromanage and control the program for his own political ends. These "vision" statements are never worth the paper they are printed on, especially when coming at the behest of the bush administration. (courtesy http://www.astrobiology.com/news/viewsr.html?pid=11605) Guiding Principles for Exploration a.. Pursue Compelling Questions Only that has nothing to do with manned exploration. a.. Exploration of the solar system will be guided by compelling questions of scientific and societal importance. The only compelling question the Bush admin wants answered is "Can we beat the chinese back to the moon and waste hundreds of billion in the process?" b.. Consistent with the NASA Vision and Mission, NASA exploration programs will seek profound answers LOL. Yeah, profound answers to how many astronauts we can sardine into a mars capsule and get killed in a futile bid to get them to Mars -- so they can sit around and do nothing. This so-called vision statement contains all the usual moronic drivel, just as I predicted. to questions of our origins, This from a president who claims a literal belief in the bible and the genesis account. Not likely. whether life exists beyond Earth, and how we could live on other worlds. We know what it takes to life on other worlds. We need to spend the money developing the survival technology, rather than wasting 1.5 trillion on manned stunts. a.. Across Multiple Worlds a.. NASA will make progress across a broad front of destinations. b.. Consistent with recent discoveries, NASA will focus on likely habitable environments at the planet Mars, the moons of Jupiter, and in other solar systems. Yep, whatever you say. c.. Where advantageous, NASA will also make use of destinations likethe Moon and near-Earth asteroids to test and demonstrate new exploration capabilities. a.. Employ Human and Robotic Capabilities a.. NASA will send human and robotic explorers as partners, leveraging the capabilities of each where most useful. Only they know without question that the robotic missions are superior in just about every respect. Perhaps in 1969 we didn't have the robotic technology to land on the moon, grab some rocks and return. However, we certainly have that technology today. The best role for humans is as mission controllers back on earth. Perhaps if we developed a better, more reliable, deep space communication infrastructure then we'd actually be making a prudent investment that would pay dividends on future exploratory missions. b.. Robotic explorers will visit new worlds first, to obtain scientific data, demonstrate breakthrough technologies, identify space resources, and send tantalizing imagery back to Earth. c.. Human explorers will follow to conduct in-depth research, Sorry, but any research that a human could do, "in-depth" could be done by a robot as well or better, especially if there is a human controlling it. At worst, the robot will be a litle slower and I know our hyperactive president can't stand that. Fortunately, it looks like he will be kicked out on his ass by next year and then he can do whatever hyperactive nonsense he wants. Getting back to the whole robot and human thing, we can't expect to just send one or two probes and then humans. We need to send probe after probe to look at things in depth. The money that we spend on the robotics program will have important spin offs here on earth. Not so with a great deal of manned space technology, which would primarily be useful only off-world. rest snipped -- __________________________________________________ ___ Quibbler (quibbler247atyahoo.com) "It is fashionable to wax apocalyptic about the threat to humanity posed by the AIDS virus, 'mad cow' disease, and many others, but I think a case can be made that faith is one of the world's great evils, comparable to the smallpox virus but harder to eradicate." -- Richard Dawkins |

Surveyor determined that the moon was differentiated, not primitive; orbital photography got much of the stratigraphy down; unmanned sample return (like that Soviet lander) would have gotten the oxygen isotope, volatile depletion, and europium anomaly results.

The Moon has been taboo at NASA for 30 years. Bush (and O'Keefe) lifted that taboo; in fact it has been completely reversed. Much as I hate Bush as a president, this is undeniably the best thing to happen to NASA in decades. ,------------------------------------------------------------------. | Joseph J.

President Bush seems to be calling for both. ..... It would be inordinately dangerous with present technology to do any kind of detailed science with manned missions .... The reward is that scientists could be on site, doing the research themselves.

Better to put robots down there and the scientists can stay at home where it's safe. Thing that would work? Want to tell archaeologists, geologists, and researchers in other fields who traditionally do field research that they should stay home and send robots? Oh, wouldn't they love to hear that. ....

Relying upon it for a manned program is crazy. That's like saying Columbus shouldn't have sailed until jet aircraft were available, or Lewis and Clark shouldn't have gone on their expidition until the Ineterstates had been built and off-road vehicles could be used. Our technology is more than adequate. The main unknowns are with regard to living in reduced gravity for a prolonged period and radiation protection from solar flares. .... Fortunately, it looks like he [Bush] will be kicked out on his ass by next year and then he can do whatever hyperactive nonsense he wants. Maybe he will; maybe he won't. One week ago, Dr. Dean was the front runner. I wouldn't call him that now, especially with Walter Mondale endorsing John Kerry.
