Can mars be colonizedby humans?

This is a brilliant thought. Please read the book "The Case for Mars" by Dr Robert Zubrin, PhD. for a nuts and bolts down to earth scientific discussion of what it would take to put men on Mars, and ultimately to turn Mars into an Earthlike planet. It is available on amazon.com and in many local bookstores. I highly recommend it.

yes, indeed we can . The recent explorers made the discovery of water in ice form can be a good source of supply of organic  chemistry survivng there. While the scientists are reseacrhing  on the survival conditins of us on Mars are aroud 60 pecent if all the conditions are satisfied. In short answer, yes we can not only set foot on mars but also find a way of living on it.

Mars could, since there is carbon there and it's got its own protective layer the only thing left is water.... there is some evidence that mars has got water in it so we could take that risk\n\nanyway if the time comes then we'll probarbly have some way of sombining the hydrogen to the oxygen- making water!

Colonize in the full sense of the world, as in living there for an indefinite period of time, never, at least in those places. Not Mars or the Moon. People will live there for some periods in their life, though, but not "colonize". Too resource-consuming. Moon: 2035. Mars: 2060. Others in our solar system: 2100. Outside of solar system: 2300.\nThat of course if there's no nuclear holocaust.

It's not so much the Martian life that might have been there, but rather, the Earthly life that we could send there in the event of, oh say, an anticipated global-killer meteor hit here until everything cooled down and Earthly re-seeding could begin. Aside from that, we humans, we explore.

Looking at your question I would say that there are a number of ways to colonise the solar system.\n\n1.) The first step is to get a reliable transport method that would get humans and materials off the earth and into space - preferably into earth orbit. It would also have to work the other way.\nThe space shuttle is an engineering disaster - it's ridiculous that the heat resistant tiles have to be applied by hand. The chinese are using oak as an ablative sheild  \nPossible replacements for the space shuttle are: \na.) A dual launch system like Space Ship one. Where a carrier plane carries the space pod into the upper atmosphere and launches it there. The space pod will then head for space.\nThe technology exists for the atmospheric ram jet the pod rocket engines need to be advanced to get to orbital height.\nb.) A ground based laser array burning the chemical fuel on a space pod.  Technology still required laser development and fuel development.\nc.) A magnetic rail track accelerating a space pod and launching it from a high mountain - feasible with current technology. Or shooting pods from a giant cannon - the idea was first mooted in Jules Verne's the first men to the moon - very feasible.\nd.) The ideal would be a beanstalk between the earth's surface and a geo-stationary asteroid. Though materials with the necesary tensile strength have been found, they are fractions of a millimeter long, the technology needs to be developed to create 36 000 kilometer long strands. \n\nThese earth to space craft (except for the beanstalk) would have to be aerodynamic to get through the atmosphere. They may have wings or fins.\n\n2.) The space station to tranship cargo and people between space and the earth. The technology is available. The best design would probably be a donut ring or a cylinder that could be spun to create gravity. To work better than the existing space station, better solar cells need to be developed and ecological engineering would be a must, otherwise all air and water would have to be imported.\n\n3.) From the space station to the planet and asteroids and back space ships will be required. We have the technology to build rocket motors such as used on Voyager and Discovery. For cargo deliveries it might be more economical to build solar sails that would use sunlight to power the craft. Solar sails require  development of polymer sheeting. These craft would be creatures of space - they don't have to be aerodynamic. These craft could land on airless asteroids and if their rockets are powerful enough they could land and take off from airless planets and moons.  On the moon is a large supply of Helium 3 which is the perfect fusion fuel - for more efficient craft the development of helium 3 motors and power sources would be required.  \n\n\n4.) Moon and Planetry landers and launchers. These would be craft carried by the spaceships to their destinations. The design would depend on whether their target has an atmosphere and what kind of fuel is available. We have the technology to build this type of craft. Once a colony is established on a planet, it would need some kind of launching system to efficiently lift stuff out of the planet's gravity well.  The earth launchers are a possibility.\n\nMining of Cruithane would not be hard using current technology. Explosives (even nuclear bombs) could be used to break up the asteroid. Solar mirrors can be built, to refine the ore on site or melt the asteroid. If rocket motors are attached to the chunks of nickel iron - the material can be moved to where it is required. If the ore is required on earth at this stage the only delivery method is to attach parachutes to it and drop it - which could be a bit disasterous.     \n\nI don't think the frozen planets, like Sedna, Pluto & Neptune are colonisable. Their surfaces are deep frozen gases. Even a small bit of heat may cause disasterous sublimation. The tundra pipeline technology is an attempt to build a structure

Anything's possible. It has been theorized that humans were the slaves of an alien race and left to populate the earth. Plenty use Egyptian mythology to base their answer, and actually do so quite effectively. So sure, why not?

Sorry, but there is no evidence of life on Mars.  But, scientists have very strong beliefs that it may exist on Mars and other planets.  The type of life that may exist would be microscopic.

Yes man will get to mars and probably all the other planets, but no I don't think we will ever live on another planet!

>>> Once the earth is over populated..\n\nThe Earth is never going to be overpopulated. The population is already stabilising and will begin to decline with your lifetime.\n\n>>>>>Are there evidences which can proove that\n>>>> humans can live on mars?\n\nNot a chance ATM. People can only barely live in Antarctica, and that is a place with fairly breathable atmosphere, mild temperatures and resupply possible for 6 months of every year. But life in Antarctica is still a struggle.\n\nMars makes Antarctica look like the Bahamas. Even the warmer parts of Mars are colder in mid-summer than an Antarctic winter. The atmosphere is unbreathable and we couldn't afford to re-supply more than once every three or four years. The absolute best we could hope for a few years for an exploration/research team to stay there.\n\n\n>>>>Research shws that theres life signal on mars..\n\nNo, it doesn't. Some very hopeful people and some people chasing funding have tried to spin it that way. There is absolutely no evidence that Mars has ever had life.\n\n>>>>if there is life on mars then human also \n>>> possible to live on mars.\n\nNo, it doesn't work that way. There is life at the bottom of the ocean too, and life in the interior mountains of Antarctica, and life 5 miles below the ground in solid rock. Humans can not possibly live in any of those places.\n\nThe simple presence of life does not mean that humans can survive in a location.

We are able to today.  Potential cost has been estimated at less than $30 billion...\n\nHey, I have an idea!  Bill Gates can pay for the mission, and then claim Mars all for himself, kinda like the European monarchs did with the Americas!

We, meaning you? Or "We" meaning humans?\n\nUnfortunately, you'll be dead by the time we establish a human presence.  Humans can travel to Mars, but "living" there can mean many things: If you define "living" there as simply showing up and staying for a day, then 2030 is a good estimate.  "Living" meaning "Colonizing" is well into the NEXT century!

I'd like to a base on the moon, where we can launch our craft to explore Mars.\n\nBut I do not think it will happen in my lifetime.

Maybe we should start a little closer to home...if we can conquer the moon...then maybe we can move on to others like mars and yes there is extraterrestrial life..but I have doubts they are there on Mars..We certainly are not the only Intelligence in the universe..but then ...Humans on a daily basis make it very obvious that we are far from intelligent.

Mars being very hot now is not a suitable condition for humans and plants, as we know it, to live.\nBut now that Water in the form of Ice has been confirmed, it is a possibility for us to live there, provided that the ice has to be vapourised to create water clouds, and subseqently the clouds should give out rain, and when this chain starts, the creation of oxygen could be obtained by growing plants which emit oxygen. \nWHEW. That my friend is a hectic task ahead (and probably not feasible also). So may be, just may be, that some where about at 200 years down it could be a dream come true.\n\nBesides, we would only be intruding the rules of the Nature by doing so.

Wasn't that the Mars landing?  Looking for life out there.
