Terraform Humans First, Then Mars?
An anonymous reader writes "Related to the future of Mars, NASA released the transcript of an expert panel which debated terraforming the red planet. Planetary scientists including NASA's Planetary Protection Officer, John Rummel, and science fiction writers (Kim Robinson, Arthur C. Clarke, and Greg Bear) chimed in. When asked if Mars should be transformed to a place where humans could walk without life support suits ("naked"), Sir Clarke responded, "Perhaps we should ask the Martians first." Can it be done quickly-- or at all? Is terraforming ethical? If humans colonize, are the colonists on a one-way trip akin to exile?" Read on for a bit more.
"A consensus seemed to be that like waking a sleeping giant, planet building seems possible if oxygen is not a requirement and some microbial life is dormant underground. But the question of making a planet suitable for plants alone seems to span tens of thousands of years. The remaining science fiction notion was terraforming humans, instead of planets, and making us survive on what is now a very alien world."
How Stuff Works: How Terraforming Mars Will Work
Hivemind harvest in progress..
Not that I don't like the idea of the space age where people from Earth will routinely travel from/to other planets, but it seems that pressing issues are piling up on Earth: poverty, foundamentalism, ignorance, ecological destruction and pollution, failing economies, oil wars, huge military spendings, terrorism, and many other issues.
If all these issues are not dealt as soon as possible, then, I believe, we must prepare ourselves (or our children) about huge wars, especially over natural resources. Many knowledgable people say that the future wars will be about water.
Please excuse my ecological save-the-world rumblings that may shatter your dreaming about a space future. I do believe that humanity's future is in the stars, but unfortunately there is another step before it that must be successfully completed...and every day that passes it seems more and more impossible...
Of course, you could argue that it's because they imagine something and then scientists see their ideas and say "Lets do that", but I think there's at least one other factor involved.
Or, you could argue that science fiction writers predict everything (cities on the moon, flying cars, hyperdrive), and SOME of it turns out to be possible.
Those writers who predict something possible are "prophetic", but it is largely a question of chance and selective memory.
However, I am a biologist - and I have the minimal ethical training required by my Institutions' NIH training grant.
Personally, I think it is ethical to terraform a planet which is not presently inhabited (by life of any kind.) Harm is, even in the most general sense, something you do to living things, so bringing life to a dead planet is harmless by definition.
Given the risk to the experimental subjects, I do not think it is ethical to "terraform" (or otherwise genetically engineer) human beings.
However, the more relevant question is not "should we do it?" because - we will. Ethical or not, sooner or later, some people will do it. This applies both to human genetic engineering and to planetary terraforming.
The pressing question, therefore, is how should those who choose to do these things (whatever you think about the ethics) go about doing it? Acknowledging that a thing should not be done at all, and then stepping back from that and considering how to minimize the negative imapct when it is inevitably done, can be a difficult feat of mental gynmastics, but in the coming centuries I think it it something peopole of conscience are absolutely going to have to do - in parallel with efforts to stop the more monstrous excesses from being perpetrated at all.
P.S. - Terraforming Mars will be fairly difficult. In a billion years or so, when the photodensity on Mars (and on Earth) has risen (because the Sun is getting bigger), Mars may look very attractive.
At that point, the big problem with Mars is the lack of a strong magnetic field, which makes it difficult to retain water vapor in the martian atmopshere. This is a problem now but it gets worse as the level of solar radiation striking Mars goes up.
This doesn't mean nothing can live on Mars - we can make micro-organisms that could live on Mars with a, frankly, fairly modest budget and present day technology. There are some things down in the Antarctic that might be able to survive as-is somewhere on Mars (although I doubt it.)
The atmosphere is also very thin, and the level of sunlight so small, that it is highly unlikely that we will be able to warm the place up enough for us to wander outside "naked" merely by changing the components of the atmosphere (which could be done with the afforementioned genetically engineered microbes).
Covering the large stretches of the planet in insulated greenhouses (built by self replicating solar powered robots) is probably the best solution if you want a vaguely earthlike environment. This can be done well in advance of the billion year timeframe, of course, and allows you to retain water vapor and a very high temperature.
The good and new comes from no quarter where it is looked for, and is always something different from what is expected.
Anything AlphaC has to say about terraforming was said better by the Mars trilogy. You have the Greens led by Hiroko who say that life will find a way and cannot be denied. You have the reds originally led (however unwillingly) by Ann who says that it is nothing less than criminal to terraform a world that you do not understand and will never understand as a result - any life which might be present on the planet will likely be destroyed and/or become indistinguishable from the life you spread upon it. You have the pure scientist (Sax) who wants to terraform Mars for his own convenience (a common theme in scientific development) and just to see if it can be done, how it can be done, et cetera. And so on, and so forth. In fact if the books have a failing it is that the characters are too transparently archetypical, but nonetheless they're books that I read eagerly, seldom stopping, and still reread periodically. The space elevator, terraforming of assorted planets, and even modification of humans for life on some of them, meeting the planets halfway. Truly amazing stuff and much more insightful and realistic than AlphaC, however good the game is - and it is.

Your english is fine.
I'd imagine a few problems with teraforming Mars..
First off is the point that you made. If we use some process to make the atmosphere more earth-like, we could encourage the growth of anything that may be lying dormant there, or we could kill it. We've only explored a very small part of the planet, and still don't have complete information about everything we've found. For example, what are those little balls that they found in the soil? Probably just rocks, I'd imagine, but maybe not. They have found traces of water (mostly mud-like). I'd imagine that we'd do something with the free-standing water, to get it to vaporize, making the atmosphere thicker, which would also likely start weather patterns and rain.
To make the atomsphere more earth like, we'd probably send some plants over, such as algae, and maybe grasses. As it grows, it may cover artifacts that could be interesting. I'll use my own back yard as an example. When I moved into this house, the yard was all dirt and rocks. We spent a week digging up rocks, but there are still some small rocks in the dirt. We then planted grass. The yard is now very lush and green, but it is hopeless to think you can see the little rocks that were there.
Imagine "teraforming" Giza (Egypt). Occasionally, archeologists find interesting rocks, like the Rosetta Stone, simply sticking out of the sand, because wind blew sand away from it. If someone encouraged grass to grow there, through aquaducts and irrigation, sand wouldn't blow away, and whatever is burried will remain burried until someone tries to build a strip mall on top of yet another unidentified tomb.
Personally, I'm all for teraforming Mars. For a long time, I've believed that for Humanity to survive, we *MUST* have colonies on more than just Earth. We have the technology to kill everything on this planet in minutes, and it takes a mistake by one person to start that chain of events. Maybe through our own greed and industrialization, we've already set the earth on a fatal spiral through pollution. There are also other events that can happen, which are on more of a sci-fi scale. What if the sun goes super nova? What if a giant asteroid crashes into the earth?
Sure, we don't have the technology now to colonize a planet light-years away. Just like a child, we need to learn to take baby steps, before we can run. Mars is becoming close enough for us to 'practice' on. It probably won't be perfect, but it will be an attempt. After several attempts, we'll do better at it.
If we never teraform Mars, if humanity debates it for the rest of eternity, we'll never learn to travel faster or further, and doom ourselves to eventually overpopulate the Earth and die.
Likewise, if we never populate Mars, our space travel technology will be very slow to grow. Necessity is the mother of invention. If we have a need to travel the distance between Earth and Mars faster, someone will invent something which can achieve this. It may not be a super-cool spacecraft. Our own science fiction has eluded to creative solutions, although technologically impossible at this time such as Wormholes, transporters, and 'Stargate' (good show).
Eventually, we will have the technology to go to distant galaxies, but we have to manage to at least get people to the next planet first. In the last 100 years, we've come a long way. The wright brothers flew their first powered airplane in 1903. Now we can fly all the way around the earth at several times the speed of sound. Wars do great things for technology. Jet and rocket powered craft were innovated during WWII. Slow progress has been made with other forms of aircraft. The cold war was great for pushing space technology, even if it was only for political reasons. America had to do better than the Russians, so we were each trying to out-do each other.
