North Korea sees nuclear-armed ICBMs as a way to keep the United States out of any future military campaign to conquer South Korea. They reason that wiping out thousands of people in Alaska and Hawaii will deter the U.S. from protecting South Korea. GBMI takes out North Korea's trump card.
Now there's a scary thought. I never considered the possibility of N. Korea using its nuclear arsenal as a diplomacy weapon to keep other nations from running to S. Korea's defense. Since it's obvious nations won't respect paper treaties concerning nuclear weapons programs, a missile defense shield may not be as preposterous as it sounds.
I like the idea of a Mars Society keychain. I usually shy away from things like bumperstickers, but not keychains. I think a MS keychain would go well with the NASA keychain I already have. And I agree about Adrian's logos, they're simple but highly effective. The current MS logo feels cluttered, it's trying to show too much and not everyone is hip to the idea of terraforming anyway so I think that "blue sky" portion should go. Something along the lines of those New Mars crescents would make a good logo for the Mars Society I think.
Just recently, on the cover of one of the 'big glossy' science magazines, they showed a very exciting artist's impression of a full-scale elevator with all the trimmings.
This was no thin 'ribbon'. This was a thick strong column with the ability to carry two lanes of traffic ... one going up and one coming down. This latter point is important because Arthur C. Clarke's concept (and maybe that of others too) included the neat idea that, using superconducting technology, the potential energy given up by the descending vehicle is used to power the ascending vehicle on the other side of the cable.
That way, ground-based lasers beaming energy to the ascending vehicle are no longer required. With minimal energy losses in the system, the cost per kilogram of putting mass into geostationary orbit becomes almost trivial.I love it, I tell you!! I just LOVE it!!!
Imagine that, getting into space for practically nothing!
Now I'm really pumped to see Brad get that elevator built. Once a space elevator is shown to be practical, it's only a matter of engineering to beef the concept up with the technology you mentioned. Who knows, in fifty years we might be able to lift thousands of tons into space for what it costs to put a microsatellite into orbit now, perhaps even cheaper than that. Have you read that one novel by Arthur C. Clarke that's about a guy trying to build an s.e. by any chance? I plan to get around to reading it one of these days.
By any measure, First Words was a complete success, and it's still generating good publicity; I'm being interviewed by a Japanese radio station live, on air, next week - about First Words, of course. Everyone who interviewed me expressed their belief that the competition was a wonderful idea that would interest everyone.
Wow. Are they going to translate what you say into Japanese or is it an English language station? Or maybe you already know Japanese. I took Japanese in college but I've probably already forgotten nine-tenths of it.
Mining Deimos and Phobos to build O'Neill cylinders, bernal spheres, toruses etc. may be easier than mining Earth's Moon. We might see the martians build more space cities in orbit and in the asteroid belt than will ever be built by terran civilization.
If a significantly sized Martian civilization develops I think they'd be far more likely to be spacefarers than people on Earth. Not only does their low gravity make it easier but they'd already be accustomed to living in spacecraft-like environments and there'd be a lot of economic incentives to getting out there in the asteroid belt. Personally I hope it happens. I think such a culture will aid us in our ultimate drive to the stars.
I guess this is a bit of a digression from the topic, but I just wanted to express my support for a space elevator, too!
I've noticed Phobos keeps coming back to the elevator in his posts, and I think his enthusiasm for it is very well founded.
If we can erect a half dozen of these things at intervals around the equator, all the other discussions of heavy-lift vehicles and riding to Mars in small dangerous 'tuna cans' will be moot.
The difference it will make to humanity's spacefaring capability will be enormous.I think maybe we should just drop everything else and make a concerted global push to get the first 'beanstalk' up there as soon as possible!
Yeah, you can probably count me an official space elevator nut. It would provide enormous benefits to spaceflight. Not only would it be vastly cheaper than putting payloads into orbit using old fashioned methods, it can also throw payloads on trajectories to the Moon, Mars, etc. You'd only need to take enough fuel to make minor trajectory corrections and landings. Personally, I'd have no problem with dropping practically everything and working full blast on a space elevator. I think space elevators will be way more likely to open space to the masses than heavy lift rockets.
Do we even have the capibility of building an elevator capible of lifting from the Earth's surface to geosyncrinous orbit, everthing I have read has stated that modern material science is incapible of building a strong enough teather, even from pro-elevator sources. An elevator capible of moving payload from a low to a higher altitude is quite possible, and would be a good investment.
A HLV is needed to build an elevator anyways, so we need to concentarte on step one first. A cheep HLV would change everything.
If Highlift System's concept for a space elevator is valid, the only component we're missing is a strong enough tether, a target which isn't too far off. Right now they've been able to make carbon nano-tube doped materials that have a strength over 1/4 of the that needed for a space elevator. It's only a matter of time before they get the strenght that's needed. And also the counterweight in geosync orbit would have to be about 700 tons, so you'd only need a handful of launches with existing boosters to get it up there. Brad Edwards thinks he can get the elevator up there in less than 20 years. His ideas seem solidly founded in physics with no miracle technologies needed and his resume points to him being anything other than a crackpot, so I think there's at least a fair chance he'll be able to pull it off. I certainly hope so.

OK, imagine the human race run amok, people breeding like wild, AI machines self replicating and tearing up asteroids and moons to build "space colonies," the whole solar system turned into an artificial habitat for human rabbits...doesn't sound good.
Ah cynics. Gotta love 'em. Well I better get back to mining some asteroids and breeding like a rabbit.
Actually, Phobos, I heard that musical instruments tend to degrade rather badly in a space environment.
Apparently they just break in half for no obvious reason!
Thanks for the heads up. I'll be sure to bring along enough tape and glue to keep the accordion alive and well all the way to Mars. I'd hate to see you deprived of your beloved accordion music.
I'd rather go to Mars with family, or at least with rather well known acquaintances and friends, rather than with out-right strangers or casual acquaintances...there can always be VERY unpleasant surprises with the latter. I found that out the hard way 11 years ago, and hope never to repeat that mistake.
Yeah, it'd be nice to weed out the control freaks and incessant complainers in advance. I think one of the reasons that cosmonaut brought up for families being the ideal spacefarers is that they've usually already worked out ways of solving problems when they arise and they don't get into ego battles as bad as a bunch of hotshots. The cosmonaut seemed to think that over a long enough span of time, the egos of a crew could create a situation ripe for murder.
It reminds us how dangerous rockets are, doesn't it? And puts into perspective how infrequently a Russian rocket fails these days - they're so reliable that this event comes as a shock.
Do you know when the last Russian rocket failure occured? I can't recall any in the 1990's or later, at least ones that blew up before delivering their cargo.
The news article says it is a similar type of rocket which will carry persons to the space station very soon. Yipes.
What made this rocket explode, does anyone know? Without getting super-technical, please?
Actually that rocket that blew up has a very good track record of taking people into space. It's just a freak thing that happened. I have no idea what made it blow up.
Hey, turbo!
I think Earthfirst is only kidding around ( ... I hope! ).I had trouble interpreting what he said, though. Who was it, speaking of America and Britain, who described them as two peoples divided by a common language?!!
NASA's budget is a pittance compared to the funding that's allocated to social and military programs. And anyhow, as the old argument goes, if we wait for all of our problems to be solved before we go into space, we'll never be going into space. I think its good to have an organization like NASA that mostly focuses on developing technology for peaceful uses. A lot of that "useless playing around in space" provides good technology that has applications here on Earth that doesn't involve killing people.
I think NASA is half-way serious about sending people to Mars, but I'm not sure they'll do it before we're all fossils in a museum exhibit somewhere. Like Josh (the other Josh ) mentioned, if NASA doesn't send someone to Mars maybe in a few decades a non-governmental organization could scrape together the resources for a mission if launch technologies like the s.e. become a reality (and I think such people would likely strive to establish a base on Mars rather than doing one time shots.) I guess time will tell.
*How terrible!! I didn't want to start a new thread for this, and thought it'd best fit here; some of you may have already heard this news:
Very tragic. It's bad enough when the rockets explode and no one gets hurt. I wonder if the soldiers were in any kind of bunker when the thing launched, seems like they would have been. Maybe some of the debris just flew a very long distance?
I wouldn't take anybody because they'd probably start to annoy me with their bitching about how bad it is on Mars and blame me for talking them into it. I'd rather just go with people who have some sense of what their getting themselves into. Anyhow it's interesting that Shaun and Cindy would take fellow family members. I read an interview with a cosmonaut who said that families would make better spacefarers than just throwing a bunch of random people together. I don't really remember his reasoning though. It was an old article at the National Geographic website (might still be in the archives somewhere.) Actually I take back what I said about taking nobody. I'll take Shaun, I forgot how much he likes accordian music and it's always nice to have a captive audience.
While it seams like a waste of resources for the retern of 10 kg of samples, one of the main goals of the sample return mission is to test technologies which are to be used in future human missions. Having the craft produce propellant on the surface, and rondezvous in orbit with a return vehicle are likely going to be included in an actual human mission.
Are they planning to do in-situ propellant production in the Mars sample return? I don't recall that being a part of the mission but my memory might be hazy. If they are going to do that though there's no sense in having to do orbital gymnastics to get the capsule back to Earth. It'd be easier just to have the thing produce all the fuel it needs to directly return to Earth from the surface of Mars.
Getting to Mars is a thousand times more difficult then a suborbital flight. It may be used as an encouragement for all the national space programs to get their acts together.
I don't think governments would really be encouraged much by a prize since their way of doing things is to inflate the cost about 2-3000 times what it could have been. ??? If we can get a space elevator built, I think there's a slight possibility that a non-profit organization might be able to rack up enough funds to send a few people to Mars. It just depends on how advanced our technology becomes in the next few decades if they do get an s.e. built.
Thanks for trying Phobos!
But I'm a bit concerned about you putting on your metal helmet....
PUTTING IT ON !!! .... GOOD GOD, MAN !! ... WHATEVER POSSESSED YOU TO TAKE IT OFF IN THE FIRST PLACE ?!!!
![]()
I took mine off once. And that was when I woke up face down in the dirt, just outside the perimeter fence of Area 51, with the strange red marks on my forehead and the bar-code behind my left ear .... and the headaches ... Oh God, the awful headaches ... !!!
:0
Don't blame me!!! I didn't take it off!! I just told the barber to cut around the edges of the hat where some hair had grown out, but before I could react he took the whole hat off and scanned my brain with a pair of mind-reading scissors. Is there no end to NASA's treachery? I fear that's what went wrong with the forum, they saw that we knew too much about, what was that again? What's my name! HEY WHERE AM I!!!!
It appears Shaun stumbled onto a new gremlin. There appears to be a major malfunction in the "Face on Mars, Hard evidence wanted, please" thread. I posted four messages but none of them appeared. Maybe all those NASA moles hacked into the forum to hide the truth. *puts on metal hat*
If Cindy's trick doesn't work just post another message and that should bring the hidden messages into view. Just call the page revealing post a place holder page or better yet use the opportunity to jump on your soapbox.
Once fossil fuels run out, we will have no other choice but to invest in more renewable energy resources. Some speculate that there will be a huge social catastrophe, since the world would basically stop functioning over a period of a few months. All international travel would just cease to exist. Boom. No more imports or exports. But I don't see that happening; we have a hundred years or more until oil runs out. And by that time we're going to have renewable energy, someone will definitely jump on that bandwagon, due to its guaranteed profitability.
I don't really buy into those types of doomsday scenarios either. Hydrogen supplemented by nuclear could easily take the place of fossil fuels for our energy needs and they'd be far more environmentally friendly. And in addition many countries could be totally self-sufficient in their power production using hydrogen. You wouldn't have to import it like we do oil. So that should solve a lot of political problems in itself.
They included a repair shop and machine tools, something you won't find in anyone's plans today. And they planned for flight times shorter then or equal to Mars-24's. While it unlikely you would need to do major repairs to the ship itself, carrying extra spares, or the tools to make them, or jury-rig them, on the ground should be considered. It may be more mass, but we are talking about people's lives here.
You know, come to think of it, if we do setup a network of habs on the surface that serve as a base, it might not be such a bad idea to design a special hab that would serve as a workshop that would be loaded with critical spareparts, tools, and manuals. Actually, I think it would be a little silly not to have something like that. It reminds me of when I used to work nights in a foam extrusion plant. They had a huge maintenance department that resembled a hardware store. If a machine broke down there was no question they had the parts to repair it on the fly! Having a "maintenance department" on Mars only makes sense to me. When they design the habs they should try to use the same types of parts as widely as possible so their easier to fix. Try to use the same sized screws, same sized hoses, etc. as far as possible.
However, TR isn't one of my favorite films. Though it has nothing to do with Mars, my favorite film of that sort [mind tricks, confusion and external manipulation, etc.] would have to be "Dark City." The final scene is very poignant.
Never seen Dark City. I'm gonna have to check that one out.
Anyway, he drew a cartoon, intended to be a series, called "John Carter On Mars." I'm quite sure the character's name was John Carter. I posted about this to the civ-culture mailing list last year, when I was subscribed to it.
I bet there's a lot of Japanese animation that features Mars. I can't recall any that revolved around Mars (even though I've seen a lot of space ones), but then again I used to watch them when I was taking Japanese in college, so I probably misunderstood what was going on most of the time anyway. I love the anime names. Neon Genesis Evangelion is my favorite title even though I have no idea what the hell it means. Sounds cool though.

Humans just have to change their priorities, from ?grow or die? to ?ecological plateau,? but it's extremely difficult.
Any ideas for achieving the "ecological plateau?" I hope authoritarianism isn't the only solution. Putting a heavily authoritarian power structure in place could backfire horribly. The ecocide that has been committed in China and the former Soviet Union are testaments to that. I think some of the best methods for reducing the population and keeping human dignity and democracy intact is to encourage people to have small families (demonstrating this point on TV and in movies could have a powerful affect over time) and to also update medical technology and access to it in countries with high infant mortality rates (which is one reason some countries tend to have very large families) and to give women equal rights and educational and professional opportunities. That last one I believe is the most important as countries that have both high medical technology and recognition of women's rights tend to have the least population growth. Of course we should also switch to more environmentally friendly sources of energy, etc. The last thing I want to see is some policy where we kidnap pregnant women who don't have "birthing certificates" and force them to have abortions or do mandatory sterilizations or some other use of direct force. That's akin to legalizing rape in my opinion.
You shouldn't count on a object you launched 14 years ago to be highly reliable today. In fact, it will probably have already failed. Habs will spring leaks, engines will break, life-support and other systems will all breakdown in various ways. The craft and habs used in this program will all have to undergo maintance and more than likely replacment, which should be counted for.
Very true. If we intend to use the habs for years on end it'll be necessary to make it easy to access and replace virtually everything in the hab, particularly mechanical components. I hope they don't make the habs like they did my Mazda where you practically have to pull out the whole damn motor just to replace the starter.
