On Sun, 22 May 2005 03:12:33 GMT, in a place far, far away, lclough
made the phosphor on my monitor glow in such a way as to indicate that: Surrrrrrrrre. Just as "a really cogent and powerful reason" was required to spend *hundreds of billions* on the newest Iraq War. Of course there was in fact no cogent reason to go to Iraq. Why do you think they had to lie? There are more weapons of mass destruction in your local 7-11 than apparently there were in Iraq. Ahhh, someone else unfamiliar with the meaning of the word "lie." And the one about Iraq being behind 9-11 -- how many Americans still believe that? Why should they, or why should they ever have, since no one ever told them it was? The strawmen continue, though. |

Touche. Thank you for the correction, I was wrong to dismiss it out of hand. Certainly antimatter, or atleast fusion, is going to be necessary if we are ever to send out any intersteller probes in some century hence. Well, it depends on how quickly you want to get there. We've already sent out two interstellar probes, both called Voyager. They're just going to take a heck of a long time to get to another star system. I think however in the context of exploring interplanetary space, reaction drives powered by solar energy are realistic hopes given enough funding, and the basic physics of the first step of getting into space is the same as a bottle rocket, and likely to be for some time. Exploring interplanetary space is not all that expensive if you do what I proposed - start a long term project to place sensor satelites in orbit around all objects of interest in the solar system, followed by landers if the satelites find something worthwhile, followed by a retrieval missions if the thing found is worth it, followed by humans if there's a good reason for it. More flexible, more versatle, better equipped robots is the way to go for exploring the solar system - IMHO. Mr. a...@ has a theme that compares the human exploration of Mars to Lewis and Clark. The difference amounts to a half trillion dollars and three years in the volume of a rest room. Something is to be said for seeing it real, but I think the space suit would diminish this. There is something to be said for armchair astronauts who support machine explorers with their taxes. There are obviously men of means who are willing to pay millions for a space adventure, but mars is beyond anything but the combined wealth of nations, and I don't think the drive to explore will open their wallets that wide. A manned mission to mars isn't short of the human drive to explore, it's short of the cash. It's more than that - it's also that we're just as happy to see digital footage of a place and save a ton of money as to actually go there. If the recent Mars landers had run into a herd of Martian animals loping along, that'd be a different thing. But we're already exploring Mars, virtually, and haven't run into anything worth sending people there for. |

Well, it depends on how quickly you want to get there. We've already sent out two interstellar probes, both called Voyager. They're just going to take a heck of a long time to get to another star system. Touche. Even at a million mph it would take about 650 years to reach alpha centauri. A lot has been made of the Voyager's exit of our solar system, including the plaque, unfortunatly it won't be able to tell us what it finds. Correction, it would take just shy of 3000 years to reach the nearest star. It raises an interesting question of how to handle the situation if a civilization is found on a planet. Perhaps the craft could make an assessment of how advanced the inhabitants are. If it appears that they do not yet have telecopes, it could drop into low orbit and reflect the rays of the sun (star) back out into space to hide itself, sort of like hiding in the shadow. As it determines that larger telescopes are being built it elevates its orbit untill when the civilization reaches the 20th century stage it hides itself near an asteroid or commet. Now imagine the reverse, a robot craft that has been observing earth for say 3000 years. Our own explorers come across it and it must destroy itself to prevent technological contamination, but before it does it shares with us the extensive historical archives of the great battles, the seven wonders of the world while under construction, earthquakes and volcanos etc. If it had a telescope ten meters in diameter it would be able to make out detail down to about two inches from 300 miles up. Who knows? I think however in the context of exploring interplanetary space, reaction drives powered by solar energy are realistic hopes given enough funding, and the basic physics of the first step of getting into space is the same as a bottle rocket, and likely to be for some time.

More flexible, more versatle, better equipped robots is the way to go for exploring the solar system - IMHO. A very practical proposal, we could start with a couple of very capable rovers on the moon, the HD video could be broadcast live in case you don't have anything better to do at 2am. It might even come accross a few interesting rocks that viewers could bid for and place a down payment for some future recovery mission. A ring explorer that is actually right in the ring, robot 'bouncers' that explore the surface of asteroids, landers for europa, ganymede and callisto, all for a fraction of the cost of a manned mission to mars.

If the recent Mars landers had run into a herd of Martian animals loping along, that'd be a different thing. But we're already exploring Mars, virtually, and haven't run into anything worth sending people there for. I think the human element of exploration is exaggerated. Mastering large scale solar collection, mass drivers, recycling and sustainable life support ought to be the aims of a human presense in space but it should be kept close to low orbit for safty and supply. Your suggestion would not only generate interest in the wonders of the solar system, which would generate votes in congress, but it could even wet the public appatite for artifacts which could become a source of revinue. BTW, a four inch telescope would be able to resolve cars at 300 miles. Letting viewers operate the camera for several dollars a minute and selling advertising might make viewing earth a favorite pastime and a self supporting venture. Thanks for your post, it's good to see some common sense brought to the arguments of this thread. |

On Tue, 24 May 2005 03:17:00 -0000, in a place far, far away, Jim
Logajan made the phosphor on my monitor glow in such a way as to indicate that: Haven't seen any recent polls on that. But in March 2003, polls showed ~45% of Amricans believed Hussein was personally involved.[1] Why should they, They shouldn't have, of course. Joe 6-pack would have just as easily and more readily believed the terrorists were Palestinians, if authorities had claimed that was the case. [2] or why should they ever have, since no one ever told them it was? "In his prime-time press conference last week, which focused almost solely on Iraq, President Bush mentioned Sept. 11 eight times. He referred to Saddam Hussein many more times than that, often in the same breath with Sept. 11. Because it was all involved in the war against Islamic and Arab fascism. Bush never pinned blame for the attacks directly on the Iraqi president. Exactly. Still, the overall effect was to reinforce an impression that persists among much of the American public: that the Iraqi dictator did play a direct role in the attacks. A New York Times/CBS poll this week shows that 45 percent of Americans believe Mr. Hussein was "personally involved" in Sept. 11, about the same figure as a month ago. Many people believe the sun goes around the earth. Do you blame Bush for that, too? |

ups.com... I'm not so sure about that. I can see some monarchies exploring motivated solely by the monarch's (and others') curiosity. More for glory of the empire than personal curiousity, but that might be splitting hairs. The point is that monarchs can command an expedition to be sent, and explorations to be made, but they cannot successfully command large numbers of people to engage in widescale colonization. Therefore, when people make arguments to the effect that Mars will become the second home of humanity because me and some of my friends are intensely curious about what's there, it's not a very strong or realistic argument. And there have been colonization efforts motivated at least *partly* by the urge to explore for curiousity's sake. Name a successful colonization program in which the urge to explore was at all noteworthy in relation to people pursuing economic opportunities. Money has not been the only motivator--there have been other strong motivations, with curiosity among these. If you're only arguing that people colonize for a mix of reasons, and curiosity can be listed among them, I wouldn't disagree with that. I would only argue that the component which we might call "the indomitable urge to explore" is a small one in comparison to people just seeking better lives (read: economic opportunities) for themselves and their families. My point is that taxpayers routinely finance ventures that bring them no immediate profit (or no likely profit *ever*). But I don't think any succesful colonization efforts have ever been tax-funded. Most 3rd-worlders are not starving, and in my experience, one need not be some middle-class white male westerner to be fascinated by other worlds. I certainly understand that, which is why I said a _starving_ 3rd Worlder (discussing a specific subset of the set). I wasn't trying to make any point about ethnicity or even culture, but about economic situation. For that matter (even though the poorest in America are a far cry from the poorest in the world at large), I've observed that poor Americans don't see much point in space exploration either, and frequently decry is as a waste of government funds. If you're exploring the Amazon and find that your food pack has rotted out, you can't exactly drop by the nearest 7/11. But people *have* explored the Amazon -- at the risk of life and limb. I wasn't arguing that no one is willing to risk hardship or even death to explore. I was arguing that somebody mostly concerned with where their next meal is coming from doesn't demonstrate much interest in space exploration for the simple reason that they are too distracted with concerns about where their next meal is coming from. -- Regards, Mike Combs ---------------------------------------------------------------------- Member of the National Non-sequitur Society.

oups.com... lclough wrote: Historically, there are only three engines that drive exploration. False, and laughably so. The human motivations involved can hardly be reduced to three. Perhaps not reduced to 3, but it remains that these are the _big_ 3. Any other consideration isn't even a close trailer. Do you think the Apollo missions were motivated *solely* by nationalism, to the exclusion of the sense of wonder, exploration, fascination with the unknown, etc.? If so, you are completely out of touch with reality. The Apollo missions were motivated *largely* by nationalism, and if you can't see that, then you're out of touch with political realities. Did you even wonder why the purse-strings snapped shut so quickly? It can't be because we completed lunar exploration and thus sated our exploritory urge, because we didn't even get started, properly. The support dried up because most of the support was simply to beat the Russians to the moon, which was acomplished with Apollo 11. Everything past that was just institutional momentum. If the drive to explore was anything close to even a small yet significant part of the mix, Apollo wouldn't have ended with 17. Religious reasons come in third, and supply a handy cloak to cover the naked ambition of the first two motives. We want to convert the heathens to Christianity, or teach the natives about Islam. Again, this hardly excludes other motivations. We aren't arguing that any of this excludes other motivations. We're arguing that these are the _major_ motivations, and that the urge to explore is down on the list of minor motivations. Obviously false. You really shouldn't say something so silly, because it damages your credibility. If people weren't fascinated with the unknown, you'd see *far* less support for the space program. We are seeing far less support for the space program. Far less support than what's need to get any kind of colonization going. Why do you think they even showed the moon landing on television? People were fascinated with our unchartered, faraway moon being explored for the first time. Yes, but how quickly did that interest wane? By 13 (only 2 flights beyond the first), TV networks were reluctant to preempt "I Dream of Jeanie". Are you really dense enough to believe that fascination doesn't enter the picture? We're not trying to argue that it doesn't enter the picture. We're trying to get you to see that, rhetoric aside, it's a very small part of the picture. Now, as it happens, I agree with you that humans have a natural instinct to see what's over the next hill. It's an instinct which had survival value for our ancestors, and will once again for our descendents. We're just pointing out that in the broad scheme of large-scale colonization efforts mounted by entire nations, it's a relatively small part of the mix of motivations. -- Regards, Mike Combs ---------------------------------------------------------------------- Member of the National Non-sequitur Society.

FWIW, I don't have an "indomitable urge to explore" but I do have an indomitable urge to see large numbers of people (including me) living off the planet, or having the opportunity to do so. But I do think that exploration is highly overrated as a motivator. Very few people are that interested in it, per se. |
