is there life on mars?

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.

Still no life is mars,\nLet mars be the beautiful. if life comes there also then it will be earth.

Yes, at least for now, living on Mars is a dream. \n\nI sure there would be many reasons for living on Mars. To get away from it all. To answer questions which would not be possible to answer on earth. I would expect the reason would be the same as the reason for asking questions, to get answers.\n\nNo, living on Mars is not running away from Judgement day, but it would be a good investment as humans if we were concerned that some planet wide disaster might strike the Earth

According to current accepted beliefs, there is no people in Mars, although there has been fossils of single celled organism.\n\nWe should stick to this, until we found any further information about living things in Mars.

THIS IS THE CRAZY ANSWER>>>>>>>>\n\nyes, there are vehicles that are not identifed.\n\nIf you mean other life forms then yes and no. It depends on what you mean by lifeform....\n\nThere is lifeforms on Mars and Venus and Earth is constantly vistited....\n\nHeres the crazy part....That these lives exist or rather are made up of a diffrent vibration than the physical plane... in other words its like Earth life is like an ice cube and Mars and Venus Life is like the Gas form of water.\n\nUFO exist and are made of thought energy...they are seen only when they want to be seen. They are constsantly visting earth helping allievate the amount of radiation we emmit...\n\nThey can not interfer with HUman free will which is why they do not present themselves...

Yes. There has to be! In the trillions of stars and billions of planets, by virtue of the odds, there has to be. Will we be able to find life? Very doubtful.

Statistically, it is very hard to believe that we (Earthliens) are along in the universe, there must be something else out there.\nAt the same time, the odds that life would develop independently on both Earth and Mars in the same solar system is pretty slim (unless life is actually not nearly as rare as we might think).\n\nThere is of course a chance that life may have developed on Mars in the past when the conditions were more suitable, but so far, we havent found anything.  Although there is the possibility, I am leaning towards no.\n\nBut think what that would mean if we discovered life outside of Earth (especially on Mars), it would be the most important discovery...ever.  If life can develop independently on two planets in the same solar system, either we are very lucky, or it the whole universe must be crawling with life (or you could throw the God factor in if you wish).

It depends what you understand by "living".  If you mean astronauts in space suits and living quarters in enclosed structures I think yes, someday we will - given enough funds and motivation (perhaps a space race to Mars with the Chinese?!?).  \nHowever, if by 'living' you mean just the way you and I do on Earth, then that's another story.  Many believe that the martian atmosphere was once habitable - complete with vital liquid water, but a runaway greenhouse effect has plunged Mars into a cold winter in which liquid water cannot be found.  There are some who believe we can send plant like micro-organisms which will absorb CO2 and give out O2. In time this should make the Mars habitable once more. However, such a prospect is a bit far fetched, given the expenses and the fact that such a process will take centuries if not millenia to 'clean up' the martian atmosphere.  Moreover, it is more biologically probable that these micro-organisms evolve into a new kind of cell which adapts itself to its enviroment rather than change it.\nSo, until man finds a way to breathe and survive in the martian atmosphere, our stay there will be limited to space suits and living quarters.

LIFE ON MARS.\n\nIn 1877, Giovanni Schiaparelli produced the first "modern" map of Mars, on which he showed a system of what he called canali. Although canali in Italian means "channel", without the implication of being an artificial feature, the word was commonly translated into English as "canal".\n\n\nIn 1910, Percival Lowell captured the imagination of the public with his book Mars As the Abode of Life. Based on his extensive visual observations (and as we know today, an active imagination) Lowell painted a compelling portrait of a dying planet, whose inhabitants had constructed a vast irrigation system to distribute water from the polar regions to the population centers nearer the equator.\n\nDespite its appeal to the public, the astronomical community never gave serious credence to the details of Lowell's theory. The failure of many observers to confirm the existence of the canals eventually led scientists to suspect that their colleagues had been fooled into seeing the canals, by the difficulty in resolving fine detail from Earth and their own desire to believe. (This map, constructed from Viking orbiter images in the same format as Schiaparelli's -- south is up -- shows no sign of the canals, though a few features may have been interpreted as such.)\n\n\nBut the Lowell-inspired idea of an Earthlike Mars proved more durable. At the dawn of the space age, Mars was considered to have an atmosphere about a tenth the density of Earth's, water ice polar caps that waxed and waned with the seasons, and an annual "wave of darkening" that was often interpreted as growing plant life.\n\nIn the 1960s, observations from Earth and flyby spacecraft signalled the beginning of the end for Lowell's Mars. The Mariner 4, 6, and 7 missions returned images of a moonlike, heavily-cratered surface. The atmosphere was found to be almost pure carbon dioxide (CO2), only a hundredth the density of Earth's, and the polar caps proved to be almost entirely frozen CO2. The first global views of Mars, returned by the Mariner 9 orbiter in 1972, revealed that the planet was far more complex than the earlier flyby missions had shown, with huge volcanoes, an enormous canyon system, and evidence of running water at some point in the past. But the wave of darkening was shown to be the result of seasonal redistribution of windblown dust on the surface, the atmosphere's composition and density were confirmed, and most of the evidence for an Earthlike Mars was swept away.\n\nBut despite all these blows, the possibility of organisms on the surface could not yet be ruled out. For this reason, in 1976 the Viking landers carried a sophisticated instrument to look for possible life forms on the martian surface.\n\n\nTHE VIKING BIOLOGY EXPERIMENT.\n\nThe Viking biology experiment weighed 15.5 kg (34 lbs) and consisted of three subsystems: the Pyrolytic Release experiment (PR), the Labeled Release experiment (LR), and the Gas Exchange experiment (GEX).\n\nIn addition, independent of the biology experiments, Viking carried a Gas Chromatograph/Mass Spectrometer (GCMS) that could measure the composition and abundance of organic compounds in the martian soil. (It should be noted that organic is a chemical term simply meaning "carbon-containing", and does not require the presence of life, although all life on Earth does contain carbon.)\n\n\nLABELED RELEASE.\n\nThe LR experiment moistened a 0.5-cc sample of soil with 1 cc of a nutrient consisting of distilled water and organic compounds. The organic compounds had been labeled with radioactive carbon-14. After moistening, the sample would be allowed to incubate for at least 10 days, and any microorganisms would hopefully consume the nutrient and give off gases containing the carbon-14, which would then be detected. (Terrestrial organisms would give off CO2, carbon monoxide (CO), or methane (CH4).)\n\n\nGAS EXCHANGE.\n\nThe GEX experiment partially su

Almost any living organism could live in mars with all those elements. The only thing that MIGHT be not there is the atmosphere, it's too thin, but that might not harm those damn roaches! (I have too many roaches in my house)

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.

I am almost 100% certain that life DOES exist on other planets, and may be in completely unfathomable ways, that we could not begin tio understand.\n\nIt us very interesting that the prospects of life having once existed on Mars are become more likely, due to the significant discovery that water once was in abundance there.\n\nThe trouble with finding life in other solar systems is that the distances are just too great. Even radio waves take 4 years to reach the nearest star from the Sun, then you need 4 years for the reply. The majority of stars are MILLIONS of light years away. so EVEN if there are a Billion planets with intelligent life there is no way of being in contact.\n\nBUT I do hope I will find out that DEFINITE life has been proved to exist before I die.\n\nI find this a fascinating subject.

No one has ever been to Mars. And I'm assuming you want to konw if UFOs exist. Well then are not proven, and I don't believe they do. You're not gonna find any credible proof out there either, only a bunch of deranged people claiming they have seen them, and have been abducted.

There is a chance that there is life not on earth, but think about the perfect conditions for life that earth has: the perfect temperatures, the correct mixture of oxygen and other gases, and of course, water. If there were life not on earth, it would probally be 1-celled organisms, and not what we would expect.

There's evidence that bacteria exists on Mars.  Bacteria exists in some of the most extreme environments here on earth, including the hottest/coldest/most acidic/etc. places, so I imagine that microorganisms at the very least exist on other planets.

It's hardly surprising that we can see no sign of life out there.  Views of Earth taken from unmanned explorer craft like Voyager taken from within our own solar system show no signs of life either. If you can't see elephants, whales or even forests from only a few million miles away then looking at hazy dots that are planets thousands of light years away expecting to see obvious signs of life is a bit optimistic.\n\nIn addition, given the size of the Universe we can hardly claim to have looked everywhere whilst at the same time it seems inconceivable that some form of life has not evolved somewhere else.\n\nSpectroscopic analysis of stellar nebulae and other "gas clouds" in deep space has revealed the existence of basic organic compounds such as amino acids which are regarded as fundamental building blocks of all living things here on Earth. So if life itself hasn't been located elsewhere, some of the prerequisite precursors certainly have.\n\nThere are also several "fossils" found on meteorites believed to have come from Mars which may or may not prove to be the remains of living things which originated on Mars.

yes, they -or it- exists as u can see nasa found germs,bacteria,exstinct polar ice caps, and even a fossil of a "human" type face on mars! so yes the exist!
