'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.'"

      If you're genuinely curious about some of the reasons, I highly suggest reading Carl Sagan's Pale Blue Dot. He goes over many reasons why we should keep exploring.

      Off the top of my head, there's the extinction argument - one big asteroid impact and we could all be wiped out if we're only on one planet. There's also science. For example, we never knew about global warming until we studied Venus (he discusses that in another book, I think). 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.

      There is no one impressive reason to go to Mars, but many very compelling ones. Though the extinction risk is a big one. If we don't go to Mars, and then get hit with a major asteroid, we'll sure wish we had.

  22. We Martians ... by ignavus · · Score: 2

    We Martians would like to remind you of that famous Earthling work "The War of the Worlds".

    We could not succeed in our invasion and settlement of Earth because of your Earth's microbes and diseases.

    We don't look forward to our new Earthling Overlords, and remind you that we have our own microbes and diseases.

    That's a nice looking planet you have. Pity if anything were to happen to it...

    Really? Are you so sure? Sounds nice, but also sounds like a recipe for all kinds of bone and muscle problems.
