Further Proof of Life on Mars

I'm for it. I mean, heck, second times a charm right?

Do you have some further evidence of life on Mars that isn't being mentioned or linked to? The discover of carbonates certainly does not prove that Mars once harbored life, merely that the early Mars was more hospitable to life than we had previously known. It definitely increases the probability that life once existed on Mars, but is far from proof.

Drop enough water astoroids on it and it would generate both heat and add to the available water. Need to create a large solar lens to give it enough solar heat to sustain it.

how about we learn to take care of things over here first.

Mars lost it's magnetic field a long time ago. We'd have no shield from radiation like on Earth. Shouldn't we concentrate on figuring out how to live on a planet where conditions are perfect for life (Earth, for instance), before we try to move to other planets hostile to life? Maintaining an ecosystem on Mars would be pretty tough. Look what happened to the biodomes. The attitude that people are separate from all other life simply would not work on Mars, if we were trying to terraform it. Let's solve the environmental problems here, then apply what we learn to making life on Mars.

i think that we should terraform mars because the human population on earth is growing and showing no signs of slowing down. at some point we will have to inhabit more than one world if we are to continue to survive. there are some problems with terraforming the planet, such as the magnetic field on mars being gone. i read that there is a team of scientists that have created a machine that is able to create a magnetic field similar to earths. if we could create enough of those machines and place them through out mars, then we could create an artificial magnetic field on mars and then we could introduce mars to a more hospitable atmosphere. to power so many large scale machines we can make solar panels in space and then beam down the energy to the planet and use it for the machines. this could be a possible plan of action if we are goingto live on an inhospitable world. its a better plan than trying to restart the core of mars and it would most likely cost a lot less.

Never keep your eggs in one basket. If science and history has taught us nothing else, it should be that our time here, with this civilization, this level of technological expertise, and indeed us as a species, is limited.

You name it, one asteroid strike, a radical shift in climate, or one of a hundred possibilities, could reduce us from our current pedestal, and do so with extreme rapidity.

It is foolishness, bordering on suicidal, to think that our currently lush and habitable world will remain that way indefinately (the last 10,000 years has been pure good-luck, both geologically and climatically), or that our capabilites of expansion will remain ever increasing (How many civilizations have fallen historically?).

While we have the chance, not only should we seek to make as many places as habitable as possible, it should be a number one priority. As long as we all exist on this one rock, the threat of mass-extinction, or cultural collapse hangs over our head daily, not as a possibility, but as an inevitablity.

By all means, we should solve our problems in our own back yard, but we live on dangerous ground, in borrowed time. Some of our children had best be sent away to ensure mankinds survival. We are all family. How many familys were wiped out by the tsunami, by earthquakes, floods, fire, or other natural disasters, removing them forever from the gene-pool? To ignore this opportunity, no matter how slight, is essentially to doom your future offspring to oblivion, sooner or later.

I think we may get a small colony going on Mars at some point but Teraforming Mars? Can't see that any time soon.

As for Mars taking population pressure off Earth? We really couldn't move any significant percentage of our population to Mars. Imagine a huge colony ship with 50,000 people leaving 5 times a day every day for Mars. That adds up to about 91 million a year. But our present Birth Rate is about 137 Million a year.

i think this is an extremely bad idea because these scientist are dealing with chemicals and substances to start new life and it could possibly create the wrong type of life that want! something dangerous! it will adjust to the condition of mars and beable to withstand every other conditions that we cant live with. we would be screwed!

our forefathers came to the new world in order to escape the oligarchy of europe. they brought the best european civilization had to offer far from corrupting influence of oligarchy and the religious wars they sponsored.

we have again reached this point in history again where the only chance for human civilization to survive is to move to the new world, but today, our planet is globalized. unfortunately, we will never learn to take care of problems here first (as is commonly said). we will live in an era of decrease, of depression, and all effects of and results of the "green economy" (less and less for all, more starvation, more people dying as the elites try to press for population reduction and resource conservation). the only cure to our problems is the frontier. mars is that frontier.

the moon is where we will get our initial supplies of H3 fuel, but the persian gulf of the solar system lies in the outer solar system, and mars is going to be the new HQ of humanity as the mid point in the export of the virtually limitless H3 reserves from the gas giants to earth.

you also have to realize that all modern technological advances are spin offs of the space program. the only way to solve our problems on earth is to leave and create a new frontier. only with the appropriate stresses will we spark the innovation necessary for innovating ideas that are completely applicable to solving problems on earth.

Second, chemicals like chlorofluorocarbons are NOT greenhouse gases. They have an effect on Earth because they damage the ozone layer allowing more solar radiation to hit the surface. I believe we still do not know if Mars has an atmospheric layer that functions as the Earth's ozone layer does, and without a proper magnetic field surrounding the planet there is nothing to prevent solar winds and CMEs from blowing lighter gases like ozone off into space.
CO2 and Methane ARE greenhouse gases and there is a fair amount of these there already... we would however need to add or release quite a bit more to have the warming effect required, after which we would need an effective method of achieving the proper balance of O2, O3, CO2, N, Ar, CH4, and various other trace gases, while maintaining an acceptable temperature and pressure. Even with all this we would still need to find a way to shield against radiation of various types from various sources because of the magnetic field issue.
Yes we can make a very small-scale model of the magnetic dynamo within the Earth, but we are not yet capable of reproducing that magnetic field around a planetoid. As for the solar panels in space and "beaming" the energy back down to the surface, this is difficult and very dangerous. It would require massive microwave or other high power energy transmission, and it would have to be very accurate and precise. The slightest misalignment has the potential to cook everything in a fairly large area near the receiver facility. It would not be pretty.
And though I like the reference to the Red Mars trilogy with the asteroids that is also not a feasible solution by its self as it would require far too much energy to change the orbits correctly, would not produce enough heat, and most of that ice would evaporate into space before it fully entered the atmosphere.
I am not arguing that we should not move out into the verse (unless we want to begin discussing the human virus), but we have reached a point presently where there are 3 times the sustainable population on Earth, we have in approximately one century destroyed our habitat, there is no conceivable means of transporting enough of the population to another planetoid even if we had a few others ready to support our form of life already, and by terraforming Mars or any other planetoid we may be wiping out life that might already exist there that we just have not discovered yet... and then we are back to the human virus.
Yes H3 is not a bad start to fixing our problems, however it is not the complete solution. We do need to further development of alternative power sources that we already have and continue to search for new ones, but that only slows the continuation of the problems. We must also find ways of reversing the effect we have had on our environment, and we need to do so before we move on and destroy another world.
We absolutely have to fix the problems we have here, now. Although I do not oppose exploration of space and the proliferation of Terran life out into the verse, colonizing other planetoids as a means of survival is not plausible solution presently or likely in any of our lifetimes or our children’s lifetimes.
