'Colonizing the Red Planet,' a How-To Guide

Velcroman1 writes "A manned mission to Mars would be the greatest adventure in the history of the human race. And one man knows how to make it a reality. In fact, he just wrote the book on it — literally. Joel Levine, senior research scientist with NASA's Langley Research Center and co-chair of NASA's Human Exploration of Mars Science Analysis Group, just published 'The Human Mission to Mars: Colonizing the Red Planet.' The book reads like a who's who of Mars mission science, featuring senators, astronauts, astrophysicists, geologists and more on getting to Mars, studying its atmosphere and climate, the psychological and medical effects on the crew and other details. The most interesting bit: Levine presents is a solution for funding the trip, something unprecedented for NASA: advertising. 'The suggestion is marketing to different corporations and professional sports leagues for advertising, which is something NASA never does.'"

      Doubly so for being ignorant enough to compare apples (unmanned earth orbiting satellites) with oranges (manned mars missions).

      Then that makes it all the more remarkable that my rule of thumb about launch costs being 10-20% of the cost of the mission applies to both manned and unmanned space activities. Another possibility which I think the more likely explanation here, is that the differences between the two are irrelevant for considering cost of launch. Ultimately, humans are just another cargo.

It's little wonder that the early colonization efforts were the founding corporate enterprises.

But at some point we'll want to start eating the resources out there; the metals, the minerals, the huge amount of hydrocarbons, and that's going to mean having the technological means to go get them.

Idealism is a Golden Age SF-Star Trek notion, and not one you can sustain something as complex and expensive as space travel on. At some point, whether because we figure out some way of getting into space and to other planets for cheap or because of some sort of resource scarcity here on Earth, it's going to have to pay for itself, much as the European colonies in the New World ultimately had to be able to feed and clothe themselves, to provide the core resources and technologies to keep the people breathing.

If the question posed was limited to "How do we colonize Mars?", I suppose the big brains answering could respond in a way that allowed the book to be published, but really, any settlement of Mars would involve completely encased living - burrowing into the rock or otherwise containing the settlement, with no chance (that we know of) of ever terraforming the planet into a Earthlife-sustaining environment. For the amount of effort we'd be putting into colonizing Mars, we may as well smash a bunch of smaller bodies together and *build* a planetoid orbiting the sun at a more preferable distance - at least we could shape it to make space access easier.

          So how do we benefit by dropping back down into that particular gravity well, after spending so much effort getting ourselves *into* space? As far as I am concerned, the only reason for people to go to Mars would be to transform Phobos & Deimos, and inhabit them as space stations. If we are going to be contained in a sealed environment, the smarter choice is to stay outside of a gravity well, once we've broken free of it. If there is anything of value to an orbiting Martian colony, on/in the planet, then an unpopulated surface could be plundered for their use more readily, because we wouldn't have to concern ourselves with the well-being of "permanent" residents or life. Mars, lacking natural magnetic armour, seems better suited to strip mining, than populating.

          As the OP stated, the Moon seems like a better place to start, especially as a stepping stone to the rest of the solar system (mine ships, explorers, whatever else). Martian orbit would make a fine outpost as well, especially if it was capable of resupplying ships bent on the further orbits of planetary bodies in the system.

      Actually, to build near earth orbitals large scale, we'll probably have to go to mars first. If you are talking city sized orbital environments, you need resources, lots of resources. Moving those up from the Earth's gravity well is probably not as cheap as moving them in from comets and asteroids in the solar system. For that matter, for the investment of the first thousand or so, Mars could be made habitable enough and create a thousand times more living space than those resources could in an orbital environment by themselves. From there you have a cheaper and easier place to get materials and manufacture them. A space elevator should be possible on Mars with todays technology.

      Also, in the long run, making Mars habitable would be cheaper than orbital environments. Once you get the temperature up and atmosphere established, upkeep will be nonexistant compared to that of a similar amount of orbital environments.

The scientists responsible for the worldwide end of CFC production first started pushing for the bans after learning of the global warming that causes Venus to be 700 degrees F on the surface. We could learn similarly impressive stuff by studying Mars more closely (we've been studying Earth for a long time, so a lot of the basic stuff is covered. Mars may hold new information that is easy to discover. That may help us back on earth.)

      Also, studying Mars can help us advance out space travel capabilities so we can further study even more interesting places, like Europa, Titan, etc that will require large rockets to get to.

      Almost all of our science is limited to what is going on on earth. Surely there are physical and chemical phenomena on other planets that simply don't happen here. The more we know about those things, the more we can do for ourselves here. I personally think that science is the path to world peace. The more easily we can provide for people and the higher the minimum standard of living for people becomes in the world, the happier people will be, and the more connected we will all become.

      Space exploration also gets more kids interested in science, many of which may decide to study science in college instead of liberal arts or something. The world needs more scientists, so flashy stuff like a Mars landing can go a long way towards encouraging young people to become scientists.

      On Earth, high altitudes experience more exposure from solar radiation, particularly UV (responsible for sun burns) and X-rays. Venus has the problem that it is much closer to the Sun and hence, has significantly greater exposure to this sort of radiation.

    And at about 50km altitude (about 10,000 rods), atmospheric pressure is 1atm, temperature range is 0-50deg C.

  43. Very little? by SuperKendall · · Score: 1

    the point is there is very little ice on mars

    Compared to Earth perhaps.

    But there's a huge amount there if you are talking about a colony, and probably quite a lot more to be had with some digging.

    I admire your thinking but a ground based habitat is way safer and less prone to disaster. A floating city sounds awesome until we stumble across something like a rare Venusian maelstrom in the upper atmosphere that wipes out anything floating...

    Basically, if we're going to go off and wrestle with another planet we need to start with something weaker than us, not stronger.

      well now you're just saying "bad things can happen on venus". well bad things can happen on mars too

      and since your floating cities on venus are isobaric with outside atmosphere, a rupture would result in just isostatic pressure gradient: repair at leisure. that wouldn't present an explosive situation or a hole continuing to tear itself open. although, there is the sulfuric acid, heh

      while on mars, since you'd be living in basically pressure cookers compared to the outside pressure, every little hole in your buildings would represent a growing fissure, an emergency, or even an explosive situation

      look:

      1. atmospheric pressure on venus floating colonies would be isobaric with the outside: human friendly atmospheric pressure naturally floats on venus, like helium balloons do on earth. while on mars you'd be living in pressure cookers, constantly in danger of explosive decompression

      2. gravity on venus is just about the same as on earth. gravity on mars is a joke. this has biological consequences (brittle frail bone density, etc)

      3. venus has an induced magnetosphere from its ionosphere. mars has no magnetosphere. do your colonists like cancer? well, your buildings would have to be dense rock or metal anyway because of the pressure. but don't try building any windows or ever going outside. meanwhile, you could have windows on a venusian cloud city and you aren't dealing with any radiation

      4. the venusian day is so slow, your floating city could pick a spot in permanent twilight and move at the same speed as a walking person and constantly remain at ideal temperature and lighting. meanwhile, mars is bitterly cold and you'd have to deal with the even colder martian nights: -100 to -200 F! and your colony certainly isn't mobile: it can't move from martian dust storms. but your venusian cloud city could just float away and reposition itself from any storms. although, the 24 hour martian day IS nice

      look: both venus and mars have many pluses and minuses. but presently, viewing all pluses and minuses, i view the idea of venusian cloud cities as much more attractive than any martian colonial scheme

    A near Earth orbital environment cannot be a self sustaining colony. Mars can. The project will capture the imagination of the world, well at least the imagination of those who have one.

It should be done, not because it will be easy but because it will be hard. It's time for humanity to take a lasting step into the rest of the universe. It's time for some of us to begin to make a life off this Earth.

    At what point are we scratching an itch that developed in such a different context that there is simply no rational way to justify it anymore?

    You are mistaken in your belief that there is no evolutionary advantage to colonizing beyond earth, that we have moved beyond the context of survival. A species with a single habitat, earth in this case, is more vulnerable than a species with multiple habitats. A large enough asteroid or a large enough volcanic eruption could wipe out the species. As an asteroid did for the dinosaurs and as a volcano nearly did for humanity in the past. Our species may have *barely* survived a "recent" event:

    "The Toba supereruption (Youngest Toba Tuff or simply YTT[1]) occurred between 69,000 and 77,000 years ago at Lake Toba (Sumatra, Indonesia), and it is recognized as one of the earth's largest known eruptions. The related catastrophe theory holds that this supervolcanic event plunged the planet into a 6-to-10-year volcanic winter, which resulted in the world's human population being reduced to 10,000 or even a mere 1,000 breeding pairs, creating a bottleneck in human evolution."

    Regardless of if it is a web site or traveling to Mars, if someone says something is to be funded by advertising, what they mean is they don't know how to get the money.

    It is likely that the economy overspends on advertising by a large degree. Most of it is in untracked, and Google and others succeed with relatively limited tracking - just showing someone looked at something, not tracking it back to sales at all.

    Given the unpaid externalities of advertising -- for example, not being able to find the site you are looking for in the first page of search results, and slow loading web pages crapped up with ads, etc -- we should not encourage this type of behavior, and when two equal options are available, choose the one less advertised.
