... And then it quickly and horrifyingly turns out Mars still has a remnant of a biosphere, and of course all living 'survivor' bacteria and maybe insects and some hardy rodents, descendants from Earthly immigrants, are survivors simply because they're so good at killing eachother for the scant leftover biomass. Survival of the most vicious and insidious...

Yummie Earthlings, with biological defences adapted to a much more gentle planet are then a snack of choice for these survivors.

Explorers on Mars all of a sudden realise they're living on a battlefield from your worst nightmare: the whole planet is a biological weapon, you have to sterilize everything you use, but these buggers are hardy...

Cue flesh eating bacteria, gangrene on steroids, cockroaches that eat through rock and are themselves carriers of a plethora of virulent, poisonous hosts etc...  :twisted:

You wake up and see a dimple on you cheek and panic clenches your throat like a vise... Did the guys that sterilized artefact X do a thourough enough job?

Are the seals withstanding the onslaught of the harsh environment outside?

... Is Michael a Russian mole turned suicidal saboteur?

Is this paranoia normal? What's that smell?

Who the heck is Michael? What is this blather?

I suppose you believe humans are the only beings in the Universe. Why can't you folks talk about aliens with a straight face? I know there are UFO nuts who think aliens are dwarfish white humanoids with fat heads that fly around in spinning frizbee space ships, but I'm not one of those. I'm merely suggesting that we talk about something that could of happened but didn't.

If you land on an alien planet, you are not going to encounter animals that specialize in eating humans. I'm really not interested in reproducing pulp science fiction. Pulp Science Fiction often considered a planet Mars with all those things you suggest, but that is all garbage. What I was considering was taking only one premise, the question of what if Mars had complex life on it? All those green fat-headed martians with antenni is just crap, but alien civilizations are not, they can happen and are not outside the realm of possibility. I don't think Mars could have had a thick atmosphere with complex life on it without intelligent intervention of some kind, so the question really is one of terraforming.

Not bad, and assuming the Aliens didn't interfere with Earth too much and all other things being equal, history proceeds apace, except the early astrononers making different sketches in their notebooks, not appreciating their significance. Sir Edmond Halley never discovers his comet. Lots of speculation about the not-so-Red Planet. Edgar Rice Burrows writes a different story. Probes are sent to Venus, and then Mars. Humanhind makes its first steps on the Moon, but the shuttle doesn't get built. There is no Mars society as such is not needed. Immediately after Apollo a new space race begins between the USA and the USSR. The canals on Mars and the Boreal Ocean, and Hellas Sea are unmistakable signs of intelligence, radio contact is attempted but no response is received. No one wastes time building shuttles. Instead Saturn Rockets are utilized to lift components of an interplanetary spaceship into Orbit. The Russians meanwhile try to perfect their heavy lift launcher and rebuild the launch pad that their disasterous moon rocket exploded on. It seems that civilization on Mars is taken to be older than that on Earth, whatever is there is bound to be valuable in the competition between the superpowers so the race is on.

Why is it that people push "Battlestar Galactica" missions anyway? Someone even wrote a whole book on a "Battlestar Galactica" mission. ever read Destination Mars by Alain Dupas?

If someone is not interested in manned Mars exploration, why would he waste his time writing a book about it? Do they think big expensive missions will actually be funded, and that they can skim some money off of these lucrative government contracts? Seems some people look for more inexpensive ways to go to Mars while others look for more expensive ways to get to Mars in hopes of not going. Do they realize, the more expensive they make something look, the less likely it is going to happen? I think sending a chimp to Mars might lay to rest any qualms about the safety of sending humans there.

And what's with these scientists that don't want to send people into space? NASA's budget is a very small part of government expenditures. If public interest is space waxes and wanes, then so too will NASA's budget accordingly. People who want to probe the planets but never go there, I call "Do not touch" astronomers, they are very interested in astronomical objects, but they don't want too much public enthusiasm. If people actually go to these places, then space science will have more to do with everyday peoples lives, but the "do not touch" astronomers want to keep Space Science as an esoteric branch of physics that only they understand or are interested in.

#4379 Re: Terraformation » The Martian Chronicals » 2006-08-19 07:57:59

Hmmmm...  Aaaaaaah... No. lol

Detailed mapping operations have showed that the most recent hydro-geological (for want of a better word) features are really old. So if there was liquid water in volumes on mars, it was eons ago.

there are a gazillion of craters in the 'riverbeds' etc, they don't get there in a hundred years, but in aaaages of cosmic bombardment.

Planets don't change their 'faces' in terms of decades, it takes thousands, millions of years (geological timeframes)

I'm talking about a hypothetical alternate history here that nevertheless adheres to the laws of physics. If history was different, detailed mapping operations would have showed something different from what they historically did show, that is what I'm talking about. I'm not saying this is true. If I was going to write about terraforming Mars, it would be easier to talk about in a what if situation as if it already happened in a work of fiction. Having human characters ten centuries in the future having recognizable names and cultural references would be quite a stretch. It would be easier to imagine contemporary astronauts exploring a Terraformed Mars, that to discuss the adventures of "Blip" and "Bleep" in the fantastic world of 3006 AD, where nanotechnology does everything for them, and terraformed Mars is an emenently civilized place lacking entirely the elements of danger and excitement that make for good reading. With a Martian World that is already terraformed by the time human probes first explore it, you have an element of mystery.

#4380 Re: Terraformation » The Martian Chronicals » 2006-08-18 22:37:07

Warm Mars with the Sun, Cook the Earth!

As Venus is the Earth once was.

As the Earth is, MARS once was.

(the earth, being shrouded in total cloud cover, had some protection)

(3billionyearsisalongtime)  8)

The greenhouse effect would have to be greater on Mars than it is on Earth for both planets to be habitable. If Mars has a 1-bar atmosphere or greater, you'd have to stack it up higher under Martian gravity than you would on Earth, all that extra air mass would have a greater greenhouse effect than it would on Earth, that would amke such a hypothetical Mars warmer than would an Earth-sized World at Martian distance. Harry Turtledove once wrote a novel about a hypothetical substitute for Mars in the form of a planet that was slightly larger than Earth, he described an icy world covered with glaciers or a planetary Antartica of sorts. A terraformed Mars would be warmer than this.

In terms of a Novel, how can you explain how Mars might have been already Terraformed when Earth astronomers first looked at it? You can be creative in this answer.

One possibility is that it was terraformed by aliens from another star system, either for themselves or for some other inscrutible reason. Perhaps the aliens originate on a Mars-sized satellite of a gas giant, and the tidal forces were sufficient to keep the geology of this moon active and the atmosphere thick. Now as the aliens traveled the stars, they found that such arrangements were uncommon, and the planets most suitable for life were Earth-sized and therefore unsuitable for them as they were used to lesser gravity. The visited Earth and found an intelligent race living their during the stone age, but the planet was not suitable because the gravity was too high for them. Mars had the right gravity, but it was dead, so the aliens used their considerable resources and technology to terraform Mars and they settled the planet. After a while their civilization grew decandent, they no longer maintained their technology as they once did, and Mars began to die, in a heroic last ditch effort they dug canals prior to their own descent into savagery. If you want an Edgar Rice Burrows type of Mars, you could say they brought over some humans from Earth to be their pets or something like that. Of course they need to feed their pets, so they brought some other Earth life and plants so they could raise them on Mars and feed their pet humans with. Well something went wrong with the alien's global society, they descended into savagery, while the humans on Mars evolved a little and grew more intelligent and civilized as Mars dried out.

So what do you think, is this alternate history scientifically plausible?

#4381 Re: Human missions » Send a Chimp » 2006-08-18 22:17:23

NASA doesn't want to lose a human in space, so it designs hypercautious human space missions that cost alot, but what if we were to sent Chimpanzees in a Mars Direct Hab and land it on Mars. We could land the Hab just like we could land any other probe on Mars. The chimps would have to do little but breath, eat, and survive for the duration of the mission, and they would stay in the hab. I don't know of any way of encouraging them to get in a spacesuit when their are no humans around to encourage them. Eventually the Chimps are likely to die when their food and oxygen run out, but we can find out if they survive the journey to Mars in a Mars direct mission and see how much that costs. If the Chimps can make it, so would humans most likely. and instead of putting in excessive fail safes, we can just be reasonably cautious and balance safety considerations with lowering costs. if it fails then a chimp dies, still thats not as bad as when an astronaut dies.

#4383 Re: Terraformation » Rapid Terraforming... - ...the most ambitious ideas? » 2006-08-17 16:47:42

Don't be so hasty with this entire domes-thing. We first need to find a good enough material to build them with. Is there any ?!
See:
Human missions » Mars radiation a serious risk to astronauts.

What if the dome was a plant with a transparent membrane? The dome plant has its photosynthesizing surface on the floor beneath the dome material. The best sort of live support systems are the low maintenance ones, if you need an army of life support maintenance workers to keep it running, it isn't worth it.

I think any terraforming effort is going to rely heavily on robotics and self-maintaining systems in any case.

#4384 Re: Martian Chronicles » Do you know what book this is? » 2006-08-17 13:45:38

Has anyone ever attempted a counterfactual Martian Chronicals. I mean start with the Mars we know and then make the minimum changes to its environment so that the planet supports intelligent life and has canals on it. Suppose it were possible to breath the atmosphere and survive without a space suit? If we attempted to make astronomical Mars consistant with this fact, what would it look like? Would it still be the red planet name after the God of War or would it look different? Would it need an ocean or would canals suffice?

#4385 Re: Terraformation » The Martian Chronicals » 2006-08-17 13:39:51

Suppose the Mars of Ray Bradbury existed in an alternate history. What if the Martian Canals did exist and the atmosphere of the planet was breathable for humans and the climate was tolerable if somewhat harsh at times? But the mass and gravity of the planet remains the same. What would have had to have happened in the past to have made Mars this way? Just as an exercise in counterfactual speculation.

First question is what would Mars have to look like from a distance to have a breathable atmosphere and liquid water with sufficent greenhouse gases to keep the planet surface warm enought for liquid water to exist? Would Percival Lowell see what he imagined he saw, or would he see a bit more?

#4386 Re: Human missions » The First to Mars - Who will it be? » 2006-08-17 13:21:53

Private industry alone will not win space.

Most of these space conventions are made up of a lot of groups selling and nobody buying.

Alt.space incest, I call it.

You get a few venture capitalists who forget the lesson of spacelift is TVA, not MSN. Spacelift is blue-collar thrust, not white collar computing. Venture types will put money in low infrastructure internet start ups that need only a good programmer. But the paltry funds that would cause such a venture to lift off is worthless when trying to build real spacecraft.

So space start ups get small sums in fits and starts--use them for fine glossy ads--which they just pass around to each other or the rare investor, who glances at them before placing them in the circular file..13.

Remember, the mark of a 'good businessman' is his ability to (while eating that steak dinner you just bought him) look you dead in the eye and say--

"No."

And off he goes to invest his money in EXXON.

And--to be perfectly fair...wouldn't you?

The motivation behind all business interests is power, if they get a chance to start a political government on Mars, they may just reach into their deep pockets to do it. Money is just a form of power, and it is the power they are after, if getting a chance to start a government on Mars and become the planet's leader suits their fancy, they may just dig into their deep pockets to accomplish it. So long as "everbody owns Mars" nobody's going to want to spend the money to send people there, however if you can conquer a planet and make it your own, that is a different story. So long as Mars remains the common property of all humankind rather than just the people who live there, there is going to be little incentive to colonize the place except for enthusiast groups like the Mars Society. I'm willing to risk not getting there first, I happen to think the chances of my country getting their first are very good, but if someone else like China does it, I can accept that. If the constitution is too repressive, Mars is not going to be successful and no one is going to go there. If property rights aren't protected, no one is going to invest there. I think there is no environmental problem of developing Mars like their is with Antartica, Mars is pretty barren and no one has thus far proven otherwise. You can strip mine it, or terraform it, and no one is going to seriously object. I think Mars has a good chance in becoming a second home for humanity, the massive manipulation of the planet's environment would be unthinkable to do deliberately to Earth.

#4387 Re: Human missions » The First to Mars - Who will it be? » 2006-08-17 13:08:50

Tom Kalbfus,

Does this mean, that If private enterprise gets their first they could design the constitution for Mars ? everytime people think that government will do it the economies are business driven not government driven they wait for there handout through charges and taxes.

Why not? if the prize is the whole planet, then this may start a whole new space race and free up alot of private capital as well. You must remember that the US Government gets the money it has to spend on human space missions from private enterprise through taxation. Ordinarily a human space mission may seem like a throwaway for most private investors as their is no return. however some rich person might fancy himself as the founder of a new nation, so he might underwrite a colonization mission with his own funds, and leave a lasting legacy for is progeny. Generally the success of a Martian government depends on how open and inclusive it is. I'm willing to bet that if you increase the importance of a human Mars mission alot more people are going to attempt it. If its just flags and footprints and then good bye, then only governments may attempt this for bragging rights and propaganda. I believe the people whol colonize Mars first deserve a chief say in what sort of government it has, it would be a good idea if it was amendable so that it may continue to meet the needs of the current Martian population, but the initial Constitution should be decided by those who first colonize the planet whoever they may be. I think if properly motivated, their is a good chance the US may get their first, but who knows, other countries may think they have a good chance too as well as private corporations, why not? There is nothing that says private corporations can't start their own country. I do prefer one government for all of Mars rather than another planet with borders, competing ideologies and wars. Let the contest be decided by who gets there and establishes the first permanent human colony. The people who live on Mars, however they get there should always have the final say. Just because their sponsors give them a Constitution doesn't mean necessarily that the individuals they send their will automatically adopt it. I don't think the UN with all the Nations in the World should decide on this matter, I don't think they deserve too. Those that actually put up the money and colonize the planet should have a greater say, because without them nothing happens. The ability to get to Mars is a mark of sucess, and an indication that their system of government and the way they run their society is working. I think the capitalist democracies have a big leg up in the Mars race if sufficiently motivated.

#4388 Re: Human missions » The First to Mars - Who will it be? » 2006-08-16 12:49:56

I said NASA. I think that the current administration has very little stomach for globalism, plus for valid reasons or not many of people view the pre-Columbia ISS delays on the Russians.

I agree with this stance, I think that our exploration of the next new world should be an American (the British can come too) affair. Ideally I would like to see private industry step up to the plate, but I don't think that is in the cards at this juncture. I also think a good motivator for a continuing program is if we dumped the space treaty so that the driving ethos of the Mars program would not be 'we came in peace for all mankind' but 'We claim this next new world for the United States'. I know I'm sure I will be flame for being a jingoist or what-have-you, but every new frontier has been conquer by national expansion because that's what offers incentive, resources, territory, prestige. Plus, the Chinese haven’t signed the space treaty, and in the long run I really, really don't want to see Mars under the banner of the PRC. (Or the UN for that matter)

I have a simple proposal. Why not have a Martian Constitutional Convention? Those who can get to Mars get to participate, have a minimum number to make quarum such as 7 or 9 people and require that they stay for 1 Martian Year and then have the Convention, if they can maintain their presence on Mars, the Constitution remains in effect. If those people are 7 or 9 Americans, then naturally by selecting who gets to go, the US would influence what sort of constitution is adoped for a Martian government. Legally the Planet would count as a seperate nation, but practically it would depend heavily on whoever finances the expeditions to Mars and pays for the projects there. No native Martians can do that by themselves, they'll need sponsors from Earth such as NASA, the ESA or whom ever. You can skip the whole "Who owns Mars" issue by establishing Mars as an independent country from the get go, and then have that government allow countries on Earth to pay for various missions on Mars. Who gets sent to Mars determines what kind of society exists there, no jingoism involved. If some nation can't afford to send people to Mars, it has no business saying how that planet should be governed. We don't need a grand compromise among all the nations of Earth, that would create nothing but a UNish nightmare of nongovernment and lawlessness.

#4389 Re: Human missions » CEV is Bullshi... » 2006-08-16 12:27:37

May I be the first to say how bullsh*t this new CEV craft is.  First off, we shouldn't make a jack-of-all-trades spacecraft, it's just bad principle. Space, as a term of destination, remember, is a huge generalisation. If space is anagolous to the ocean then it would be sufficient to describe the CEV as a boat. It is simply an airtight vessel capable of transporting stuff from one destination to another. Which does nothing at all to describe its capabilities, other than it's capable of being a boat. Is it a short range passenger ferry, a small dinghy, or a disposable life raft, or perhaps a house-boat? The CEV's purpose needs to be set in concrete before we start thinking about the design and funding and such. And what of this nonsense about accelerating the design schedule? Why must NASA insist on a 24/7 human presence in space? Why? Can we even afford it anyhow? I mean look at the year 2013: The CEV will be absorbing maximum funding (operational vehicle or not), the ISS will still be occupied with a full-time crew, all the while the Moon program will be demanding huge sums of money. We simply can't afford all three pursuits. We have to drop atleast one, preferably two. The ISS should go ASAP, so why can't we kill it in 2010, with the shuttle? That way we wouldn't need to accelerate CEV development, which we couldn't afford anyway, and we can put full effort into the Moon-Mars program.

We already have the ISS to hold us back, we don't need the CEV to justify the ISS when it is complete; It'll be just another shuttle. Pointless mutual justification. Kill them both and concentrate on a dedicated 'Moon vehicle', not CEV.

How do you make a dedicated Moon Vehicle? Even the Apollo Capsule wasn't a dedicated Moon Vehicle, as it docked with Skylab and the Soyuz Capsule in 1975.

#4390 Re: Terraformation » Terrform Venus » 2006-08-16 12:02:00

No excess CO2 on Venus. The same amount we have here on Earth`s crust and fluo-spheres. Just the carbon is in non-proper form on Venus. To expell the CO2 off-planet is pure waste of resources. Venus needs H, to sequester the carbon into rocks, carbohydrates, etc... This H, may come from the planetary mantle or from the Outer System or from the Sun... Imagine "atomic laser" solar -powered, harvesting H from the solar atmosphere and precisely dumping it into the Venusian atmosphere. the "atomic lasers" spit with velocities of 10-100 km/s - hence the receiver on/around Venus also would work as powerfull powerplant for the other necessary works of global environmental conditioning... Like a MHD converter...

I disagree here.  Venus has LOTS of excess CO2, and while a good portion of it could be absorbed into a biosphere or otherwise contained in the planet, the vast majority of the rest of it must simply be disposed of some how.  Venus is of similar size and mass as the Earth, yet has a CO2 atmosphere 90 times as thick (9.3MPa).  Removing the vast majority of this gas in some fashion is a primary step in making Venus liveable.

As for the removal of CO2 being wastefull, I disagree.  Especialy if we are taking it out of the atmosphere via solar-hydrogen.  If we realy needed vast amounts of carbon that much (and I don't see why we should), we could simply capture carbon from the sun via a similar process.  The sun has trace amounts of carbon in it, which is way more carbon in it then we would ever need.  Certianly blasting it off (via a enourmous impact), frying it off (via mirrors as I propose), or freezing it (with a huge shade) and tossing it off (via mass drivers I suppose), would all be far more expedient as well.

What is the easiest way to get rid of the carbon dioxide energy wise?
1) Is it easier to scoop it up out of the atmosphere and send it hurtling into space at escape velocity?
2) how about disassociating the CO2 into C and O2? C is a solid, and the O2 we combine with hyudrogen to make water.
3) Compress the CO2 and store it underground on Venus.

#4391 Re: Martian Politics and Economy » Martian Society and Government » 2006-08-16 10:53:51

No two things in this world are ever equal, that goes for people as well. The sort of government decided for Mars will be determined by the founders of the Martian society. I think the most we have to agree to here is to decide on how the Martian Constitutional Convention is to be convened by the first settlers on Mars and on what is the minimum number of people on Mars required to hold a Constitional convention and decide on what form of government it is to have.

If I was one of the founders, I would want a system where each citizen gets on vote in choosing the government. Elected representatives should be required to run for reelection in a contested election if they are to retain their posts. The voting should be as inclusive as possible among the people living on Mars. Naturally the Nations participating will have an indirect influence on this process by choosing who to send to Mars. If the United States gets their first with colonists, then naturally I expect the government to resemble the structures of the United States, as it is in the US national interest to export its own form of government. Naturally if the colonists are to form a government there, they have to stay there. If the colonists settle, decide on a constitution and then vacate the planet leaving it unpopulated, then the work is undone and the process must begin over again from scratch. If the US or some other country really wants to set up a government there, it must be prepared to maintain a permanent settlement on Mars. I figure just be fair to other competing countries, the colonists must stay on Mars for the duration of one launch window to the next, if another set of colonists arrive, they can then participate in the constituional convention.

I found Kim Stanley Robinson's third book a little difficult to swallow, it was too preachy and political for me, sort of putting "Capitalism on Trial" so to speak based on its fictional representatives in the form of Transnats in the book waging war on each other. I would avoid socialism and too much regulation on economic activity if at all possible. Freedom should be maximised, and economic decision making should be up to individuals rather than governments. The less regulation and red tape the better. I think property rights should be sacrosanct. If Kim Stanley Robinson's book, all the investors on Earth got screwed. If the investors feel they won't get a return on their investment, private capital won't be forthcoming. Would I be willing to invest in Mars if I felt the Martian Government was going to eschew all debts and nationalize all private property, leaving me with nothing? No, I don't think so. My advice is to beware of Third World Government practises such as exproppriating private property or forcing "sales" to a restricted number and kind of buyers or to the government. All settlers on Mars should be guaranteed a return trip to Earth if it turns out that they can't support themselves economically on Mars, that means the price of a ticket should include the price of a return trip. Martian society in its infancy shouldn't be burdened with too many welfare obligations, all citizens should contribute, at least among the initial colonizers. Criminals should likewise be deported to Earth, so as the spare the Martian government the burden of maintaining a Penal system.

#4392 Re: Human missions » Ares and Ares » 2006-08-16 10:20:13

NASA's proposed Ares rocket bears some resemblence to Zubrin's Mars Direct Ares Vehicle proposed in his book the Case for Mars. Just how suitable would NASA's Ares Rocket be in launching a Mars Direct Mission, and also what are the differences between the two vehicles?

#4393 Re: Martian Politics and Economy » What Type Of Government Should Mars Have?? - Mars Government » 2006-08-16 10:08:55

The Mars government should rightly be decided by those people that live there. By carefully selecting who to send to Mars, the colonization sponsor will therefore decide on that government. This is sort of an electoral system, each colonist is an "elector" sent by the mission sponsor to Mars. Each elector will probably be sent with a draft of the proposed Martian constitution and then a constitutional convention will be convened on Mars where each of the Martian colonists will decide on what sort of government to govern themselves with and each of the following colonists will then have to abide by the constitution set up by the founders, that seems like a logical way to proceed. If at any time the population of Mars drops to zero, then the constitution agreed upon becomes null and void, and the next set of Martian colonists then become the new founders and they then decide upon their own Martian constitution which all later colonists must legally abide by.

What do you think? Is that a logical and consistant plan or what? Those that can't make it to Mars should have no say in how its governed, that is strictly up to the people that live there. Now what's the minimum amount of people on Mars required to have a quarum? May I suggest a number like 7 or 9?
