2) Replace the parachutes with inflatable balloon-parachutes ("Ballutes.") The extra buoyancy might eliminate the need for descent engines when the ERV and Habitat Lander touch down on Mars.
This could be a good idea for reducing the amount of fuel you need to bring along in order to land. Would the mass of the balloons be less than the mass of the fuel you'd need to safely land a module? Also, I wonder if it still might be better to have fuel because you can control the landing better. This might be one of those rare cases where it's better to have a more complex, but a more controllable landing system. But then again, it's hard to see a whole lot going wrong with balloons unless one of them fails to inflate. :0
I went to see Star Wars II when I wanted to blow the world up with a giant bomb, so it's possible it's actually better than I remember. I think they could have done a better job with some of the costuming though. Obi Wan looked foolish with that beard. And that whole bit with his dying mother was a bit on the melodramatic side. Even though I think Anakin had a red light sabre when he started dicing up his mother's captors. Gotta love the symbolism with those light sabres.
After the recent flaps here in the USA of a California judge declaring our Pledge of Allegiance is unconstitutional [yesterday] and today's ruling that public tax money is to be given to private religious schools as "vouchers," I'm wondering about education for children on Mars.
I don't think it's necessarily bad that parents want to send their kids to private schools, even to religious schools, with vouchers. After all those parents pay taxes to. If they feel their child will get a better education at X Catholic school and can actually educate them at less of an expense to taxpayers than would be incurred by enrolling them in a public school, it could be a positive thing.
How will Marsians ensure that ALL children are getting adequate and proper schooling? By what standards, guidelines, etc.? Would it be best to have perhaps 4 hours of "formal" education, and then perhaps 2-3 hours of hands-on education [cooking, gardening, tool making -- anything useful and productive for the settlement with an adult willing to guide and oversee the child or children]?
I think you have a pretty good teaching model. If the colony is at a severe shortage of adults who have time to teach maybe they could look into importing some teachers from Earth. It could get interesting to see what happens when those kids get to be college age and it proves impossible for their bodies to withstand Earth's gravity (assuming they were born on Mars.) Some people have banged around the idea that the first Martian colony could actually be something like a college town that trains future scientists, engineers, etc. In any case, hopefully those Martian children will have advanced educational opportunities when they get to be of age if they can't come to Earth.
Oh yeah, I've ridden the Super Man ride at Six Flags. It's my favorite ride, I love that acceleration.
1G years ago, there was no fossilized life: life on Earth existed only under the form of unicellular organisms; sexuated reproduction had just been invented; life existed only in water! Considering all the changes life has been through the last billion years, we may be too hasty when saying humanity will have to migrate when our sun explodes. The homo sapiens appeared only some 200,000 years ago and historical record dates back only to some few millenia. Even if Man doesn't exterminates himself, how long will the human race will exist? Even 1 million years is too much for one existence to grasp. Say 50 million years, all possible evolution of Mankind into its descendants taken into account. That's still 100 times less from the time it will take for the Sun to dissapear.
If we force ourselves to stay on this planet, I think it's safe to assume that humanity will die off long before the sun even becomes a danger to Earth. If we want to do our part to keep advanced intelligence alive in the universe I think its pretty much mandatory that we spread ourselves as far and wide into the cosmos as possible. I think once you have huge populations spread out into the cosmos there's a good chance that intelligence will continue to thrive for eons if not millions or billions of years. Some populations will get wiped out by natural or artificial disasters but others will be able to carry on.
Personally I have no problem with blowing up fanatical religious terrorists who want to take out their frustrations on innocent people. I guess these murderous dogs will have to learn the hardway that the USA can blow them up a lot better than they can blow us up! If people have a gripe with America maybe they should try more diplomatic routes first!
I'm wondering if the best plan would be to have the astronautical candidates spend first a few days in relative isolation, then increasing it to a week, later to a month, etc., prior to the actual flight. They're going to be spending nearly 3 years together, right? And, of course, the same should go with potential "backup candidates."
Thoughts on this?
It might be good to throw the astronauts together for a month on those Mars stations the Mars Society builds. I've often questioned the value of those stations, but they could be a good way of acclimating the astronauts to living in the hab module that will be home for three years. I imagine also that spending a month or two in such a hab module out in the middle of nowhere will give a good indication of the social dynamics of the particular crew.
The biosphere project I believe lasted a year and was self-contained. Even though the people got on each others' nerves, they seemed to have come out ok considering that they developed some problems with producing food. So hopefully it's a good indication that things can go relatively smoothly.
Someone told me today that a new Star Trek movie is in the making and that it's going to be released in December. It's going to be called Star Trek: Nemesis. I hope it doesn't turn out to be a boring flop like Star Wars II.
The window seems to open at about age ten, late third grade - early fourth grade. It seems to start closing at about age fourteen, late eighth grade. The objectives for the Mars Society Education Task Force say broadly what needs to be done.
Hello Ned. I totally agree that the time to capture the imagination is when a kid is sometime around the third or fourth grade. I've noticed from reading interviews with a lot of scientists, artists, ect that they first developed their passion for such subjects at around those times. I know I did. If you wait until high school to interest people, it's going to be way to late. And I think the education needs to be less fact based and more focused on the imaginative side and the wonderous possibilities that could result. I agree with Einstein himself that imagination is more important than knowledge. Of course you can't neglect the facts, but bare facts are boring and uninspiring, especially to a fourth grader.
haha, I bet Dayton wasn't expecting to read about some kid flying to Mars on flashlight batteries. Neither was I for that matter. I remember seeing some movie about this one kid that built a spaceship in his garage using plans out of a magazine. At the very end it showed him blasting off through the roof of the house and his parents were like "oh well."
If someone does use your concept I hope they change the name of the rocket. "Barbarian" is such an ugly sounding name for a scientific/colonial rocket. It's somewhat ironic though. I'm sure a lot of Native Americans would like to rename the Mayflower the "Barbarian."
Your post reminds me of the protestors in California, during the 2000 and early 2001 electricity crisis and corresponding "rolling blackouts"; everyone agreed that more power plants needed to be built, but nobody wanted one "in their backyard". It was rather amusing; I recall seeing protestors yelling and waving placards about not having enough electricity ::and:: these were the same goofs ranting against plans for a new power plant to be built in their county!
Reminds me of how much I'd hate to be a politician. Damned if you do and damned if you don't. Plato would probably have a field day using these kinds of examples to argue against democracy.
I read somewhere that the Russians were planning to build another hab module for the ISS that they could rent living space on. I might have been delusional when I read it though. Anyways, the ISS seems to be turning into more of a space hotel than anything else. Not that I have a problem with people paying to visit it, but as a science station I don't have the impression the ISS is even close to living up to its potential.
fear seems to be the right word because the immense possiblities really scare us out of our wits.
but like phobos said"...it can be done,it will be done"
and if that might happen ,people should evolve some strategy to ensure that we do not have to face some "super race" that enslaves the rest but a very benign form of this technology leading to fewer"natural abortions", "natural" congenitally malformed and mentally retarded children and a lot many other genetic and genetically influenced diseases.mankind it seems has again' stolen the fire' and we can use it to light our way through the future.
True. I guess we can't blind ourselves to the fact that technology that has the potential for great harm also usually has the potential for great good. It makes me think of nuclear power. I think we let our fear of its negative possibilities unduly hamper our use of its beneficial qualities.
Higher speed would also mean higher energy expenditure, which might be bad in itself.
I could stand some convincing about NERVA. But if anyone ever proposed using a nuclear Orion system for Earth launches, you would find me among the protestors chained to the launch pad.
Briefly exciting, but they won't find much of you -or the launch pad!
Well hopefully the people at the controls wouldn't press the launch button with people chained to the rocket!
Personally I don't like the idea of using nuclear pulse propulsion from the surface of the Earth either. I do like that idea of using a tether though to lift a nuclear rocket up into a safe area above Earth. With properly encapsulated nuclear explosives there'd be very little danger of nuclear material being leaked into the environment if the tether were to snap. You wouldn't have to worry about a chemical rocket exploding and potentially spreading all of those little bomblets all over the Atlantic.
Even if humans do successfully settle and/or colonize Mars, eventually our sun [Sol] will go into its Red Giant phase. It'll balloon into such a massive fireball that it'll consume Earth...and probably Mars as well. Antares, alpha Scorpii, is a Red Giant, and its circumference is larger than that of Mars' orbit around our sun. In other words, Sol is [currently] to Antares what Earth is to Sol. The sun will then either explode or implode. Any life in the solar system as we know it today will be el-extincto.
Actually, Earth could lose most of its advanced life long before the sun swallows the inner-planets in five billion years. Since the sun will be gradually increasing in brightness as it ages, it'll eventually get to the point in about a billion years where it could cause massive evaporation of the oceans and the resulting moisture trapped in the atmosphere could cause a greenhouse effect that could literally turn Earth into a planet more like Venus. Hopefully by then we'll have engines that can achieve a good percentage of the speed of light or utilize some exotic properties that are unknown to us to get out of the Solar System. With time dilation, it's possible you could visit several stars in your lifetime. Of course, once the Sun does get bright enough to turn Earth into hell, Mars will probably be a nice giant Hawaii.
We still squabble over the Planet Earth, who has the right to live where, we draw lines on maps and and insist that certain Human Beings must live within the confines and only move to another part of the Planet with permission. Earth is an Island, we have no where else to go at this time, it is our nest.
Just out of curiosity Andy Kerr, are you an anarchist (sounds like you are?) If your not and you believe in using a government to unite all of humanity, I think that could end up worse then having multiple nations. The only way you could unify the entire planet under one government, at least right now, would be to have some kind of dictatorship that would ruthelessly stamp out dissent and try to reform everyone to its way of thinking. You can argue that this is happening with "Globalist Capitalism" right now, and there's plenty of dissent against that. On the flip side, I'm not sure I'd want to live under a globalist command economy either. Such a regime would be very inimical to personal freedom. But then again maybe you were just speaking of humanity uniting in a more metaphorical, non-governmental fashion.
Even better, I think the "X-Prize" concept should be used to get people to Mars, as the government would only pay for actual results instead of incurring massive cost overruns that have nearly doomed the ISS to extinction...
I like this approach. With the gloomy scenarios you brought up with things like Social Security, this might be our only chance. I just hope cheap launch technologies become a reality sometime in the near future, technology that could be used without needing the government's budget. Of course there are countries like China that could get to Mars, but I get the feeling they're just in it for the national pride and that their space program might die out the way the U.S. one did once the glamour of spaceflight wears off.
I am not expecting this party to get a president in office by its self. No all we really need to do is show that people want Mars, and people want space exloration. Also I don't expect to convert everyone to this party, no just unify those of us who already think this way. There are a lot of us we just need to organize and motivate. This party alone will not get us in space but it can't hurt.
I think what we need is a good propaganda campaign that appeals to peoples' emotions. I know that's an evil thing to say, but hell, everybody else does it.
Robotic pets would require cost, too: The parts, upkeep, repairs, etc. I suppose a person wanting a robotic cat would like for it to have false fur, false eyeballs (where will you get those on Mars? Would have to ship them in from Earth, I suppose), and rig up a way for it to say "meow."
To be honest, I don't know which is the better ::financial:: option for settlers or colonists.
As for astronauts on missions, I do think a cat as a pet would be the best option [as I outlined in my last post in this thread].
The type of pets I'm talking about aren't rigidly programmed toys that have a very limited range of actions. I'm assuming that by time a sizable Mars colony becomes a reality we'll have the technology to compress millions of artificial nuerons with processors that could maybe do trillions of calculations per second in something the size of a cat. Such a beast would learn from its environment much the same way a real animal does and it could be programmed with a rudimentary set of "instincts" so it knows when it needs to meet bodily requirements. Such an animal would be a far cry from something you'd pick up at Toys R Us. It's possible such an artificial creature would be virtually indistinguishable from the real thing if its body could be made realistic enough. I guess it could be something of a feline Turing test.
It's true also that artificial pets would require upkeep, but I'd imagine the resources they need for power and repairs would be easier to obtain from the Martian environment.
I definately agree with that sentiment...I really don't see chimps or any other creatures being genetically "programmed" to be our "slaves." Machines are far easier to construct and maintain than living beings which would require a whole new infrastructure to keep them alive and functioning on Mars, and there would be none of the ethical issues to deal with.
I agree. I don't even like the idea of genetic programming in human populations if it's going to lead to things like "designer" babies, etc. Artificially introducing gene sequences that can be passed on from parent to child seems like a big risk. Of course there's that gray area where someone might want to cure a genetic disease they could pass on to their children by introducing genetic alterations that show up in gamete cells. Anyways, if creating smarter, more capable humans through artificial means is what we want I'd rather go the route of creating smarter, sentient A.I. and leave the human genome alone. I get the feeling though that if it can be done it will be done. In the future we might have a bunch of genetically altered human clones being enslaved by their lazy A.I. masters. Who knows.
Depends on how you define "survival of the fittest." According to the late Stephen Jay Gould, this doesn't always mean dog-eat-dog but sometimes implies that creatures can best cooperate to find an advantage against nature. Many symbiotic relationships between species are in this category, particularly in regions where nature has the upper hand and there are few species inhabiting large tracts of land (i.e., the Siberian tundra).
I especially find it odd how some people think Darwinism can be applied to societies and politics. Natural selection has nothing to do with creating a culture that seeks to reward the greediest and merciless members of its society. I think ants make a good example of a society that couldn't exist efficiently if its members were in continuous turmoil with each other. I think Hitler proved fairly effectively what kind of society we'll end up with if we go to pains to weed out those we don't think have a right to live as a kind of "forced" natural selection.
*Don't know.
What I do know is that I wouldn't volunteer to try it.
Ah C'mon, it'll be fun.
I've never been very receptive to the idea that Earthlife was carried to this planet on an extraterrestrial object. I don't discount the possibility of some rock with Martian bacteria in it being ejected into space and falling to Earth to seed life, but it just seems more reasonable to assume that Earth life started from the get-go on Earth.
*I agree. What continues to concern me the most is the impact of human sexuality on the group dynamics of the crew. There will be the potential for sexual rivalries, feelings of sexual betrayal/disloyalty, and then there is the matter of unwanted advances.
Now that's dangerous! I could easily see something like that making a mission less productive or even ruining it. Sexual harassment will definately ruin the mission if people don't feel comfortable or safe working with each other. Candidates that are prone to commit sexual harassment will definately have to be weeded out somehow. Personally I hope the mission isn't a uni-gender one. It might solve some problems but I think it would make a powerful symbolic gesture if both genders went along. I never heard the story about that astronaut trying to force himself on another crewmember, I think that's a good example of how sexual urges can become destructive on a space mission. At least we weeded out one astronaut from the candidate pool.
To get around this problem, I would propose either having married couples on the mission, so everyone's sexual needs would be satisfied, -or- just stick with a one-gender mission, male or female.
I think the married couple idea could work if the candidates aren't like some of the married people I know with their not so secret affairs. Newly weds would probably make the best choice as they're probably less likely to start eyeballing other people on the crew. They could go on a Martian honeymoon! The whole idea of marriage makes me queasy though. I just don't think people are built for that kind of monogamous relationship. A bunch of pretty words are no match for raging hormones.
It would be challenging to hammer into the social consciousness the need to go to Mars with those high price tags. We might stress the point that working to develop resources in space could help reduce the environmental strain on Earth, but such technologies would take so long to develop that the myopic public might not buy it. Got any ideas that could hook the public on spaceflight, especially Mars? I don't know if creating a party would be the most effective route. Third party political candidates don't tend to do well, at least in the USA.
