Raver32 writes "Mars will be transformed into a shirt-sleeve, habitable world for humanity before century's end, made livable by thawing out the coldish climes of the red planet and altering its now carbon dioxide-rich atmosphere.
How best to carry out a fast-paced, decade by decade planetary face lift of Mars — a technique called "terraforming" — has been outlined by Lowell Wood, a noted physicist and recent retiree of the Lawrence Livermore National Laboratory and a long-time Visiting Fellow of the Hoover Institution.
Lowell presented his eye-opening Mars manifesto at Flight School, held here June 20-22 at the Aspen Institute, laying out a scientific plan to "experiment on a planet we're not living on.""

I mean, what value could learning about extraterrestrial life have, when it's at the closest planet for several light years likely to have some similar to ours? We'll study the next one, even though that means interstellar travel.
We've proven how carefully we protect environments when we don't understand them, right here on Earth, right?

Terraforming... (Score:5, Interesting)
I do think that the time span is a bit idealistic, and doesn't account for the Law of Unintended Consequences, but the idea is sound.

The problem is you need to raise the temperature of the atmosphere in order for most anything to grow, because there's no precipitation. The cycle can't begin until you've done that first step.
I haven't RTFA, but there was a show on Discovery Channel a while back where one of the guys who had designed a series of Mars missions for Lockheed/NASA back in the 80's (and he's still fighting for them) had proposed actually building a bunch of factories on Mars whose sole output would be greenhouse gases. Their entire purpose would be to just pump billions of tons of what we'd call pollutants on Earth into the Martian atmosphere. Supposedly you could raise the planet's temperature by 10 degrees over 100 years using this method, which would be enough to start releasing the water trapped in the ground as ice into the atmosphere, creating clouds and precipitation for plants. Then you could start planting forests, which would thrive in the CO2-rich Martian atmosphere and would begin to create the oxygen we need to breathe.
Humans could live on Mars as the terraforming process was ongoing, but they would need to be in enclosed colonies until the process was complete. Eventually, though, they'd be able to venture out into an Earth-like world.
I'm curious to see how the author of this article thinks the process could be sped up - the Discovery show said it would take thousands of years given current technology before the air would be both warm enough to live in and breathable for humans.

"Will"? (Score:5, Insightful)
Mars doesn't have a carbon dioxide-rich atmosphere. Mars doesn't have an anything-rich atmosphere. Yes, what atmosphere Mars has is mostly CO2, but what atmosphere Mars has is actually a pretty decent approximation of vacuum; the thickest parts of it are barely 1% of typical atmospheric pressure on earth.
The whole article doesn't actually include any specifics, it's just handwaving of the "and then a miracle occurs" sort:
Right. We'll get right on that. We only have 93 years to go, according to this article.

What does that mean? Mars doesn't have enough gravity to hold enough gas at its current temperature. If we warm it up, that problem increases. You can't just wish that problem away. Mars doesn't need heat or oxygen to be Earth-like. Mars needs mass.

Regardless, anyone who goes through the expense of terraforming Mars, even a government, is going to want some assurance that the rest of humanity won't leech off their work.

i'm sorry, but in reailty, the balance between individual rights and corporate provenance isn't so difficult or immobile. there is no massive conflicts, and the hudson bay company still exists today: what was once the corporate master of much of north america is now simply a department store [hbc.com]. but of course, you read most science fiction, or talk to a paranoid schizophrenic, or even consult certain lowest common denominator youth subcultures, and you get the impression that corporations are these unstoppable sociopathic vampires out to turn you into an unthinking slave. hardly. reality is just not that interesting, sorry

By the time we use up Earth, Mars will be ready for wholesale migration, and by the time Mars is used up, Venus will be done simmering. By that time we will be assembling new planets from scratch with asteroids, Mercury, Pluto, Sedna, and whatever other junk we can find.

We'd have to find a way to get its dead core molten and spinning again. Otherwise solar radiation will just flay off any atmosphere we try to put there.
Maybe we could live on Mars in domes or sealed caves but I doubt we'll ever be walking about in the open on its surface.
Robots Will Colonize Mars (Score:5, Interesting)
In fact, the more optimistic transhumanists would tend to assume that people alive today may see a time when they can upload or upgrade into an advanced robotic form themselves -- so it wouldn't even necessarily be our remote sort-of-descendants who colonize Mars, it could be us, suitably transformed.
Conventional wisdom is that Mars will be explored by robots, then colonized by humans. I turn that idea on it's head. Humans will explore Mars -- today's robotic probes are too crude and limited, so that a single manned expedition could do scientific work that would take decades, maybe centuries, with robots. The other side of that coin is that 50-100 years from now humans will become obsolete for space travel and colonization. The people who actually live on Mars and build a society there will be synthetic people, not homo sapiens.
