Can Earth bacteria survive in Mars?

That`s what their trying to find studing life in Atacama desert, Chile, driest place on earth. \nProbably the answer will be yes, because of mutation capabilities of bacteria.

I doubt that Earth is the only planet in the whole Universe that can sustain life.  There will probably be some other planets out there somewhere with some sort of life on it.  Whether it's intelligent life or not is another question!\n\nThere may very well have been life on Mars, or on other planets in our solar system at one point,  but we have yet to find it, or any evidence.

First off for terraforming Mars you need to create an atmosphere.. then can you begin to "build" life on Mars..even with water you need an atmosphere..But also as stated earlier..Mars' magnetic field is not there..therefore nothing is stopping all the deadly radiations and other cosmic energies from bombarding the planet.

No, but some theories must confirm it now. The best theory is that there are water on Mars long ago. That may prov that there is life on mars. The problem is, it's not proven yet, and other theories are here.\n\nBut remember, every life in a planet starts with water, so maybe, bacteria evolved into sea animals because of water, then to reptiles, to animals, monkeys, and so on.

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.

Yes and it is on Mars! No, this isn't a joke, it's true there's bacteria there. That's life. But if you meant intelligent life, that's another story. I'm guessing there is, but it's very possible that these beings don't know of our existence or possibly know of us but would rather avoid us. Either way, is within the realm of possibility.

No.  A human will give birth to a human that is set to live nicely on earth.  It doesn't matter where the baby is born and raised, it will still need the atmosphere to contain certain gasses, and be within livable pressure and temperature.  Mars is lacking in all of these.  If it would kill the parent, it would kill the child.

Well, maybe if some anaerobic bacteria or some spores contaminated one of the Mars probes as it travelled through the earth atmosphere on its way to space and then Mars.\n\nIt is kind of a tricky problem to sterilize something here on a very non-sterile planet and send it through our atmosphere to somewhere else with not one single form of life on it.\n\nIf any life did survive the journey to Mars, and was compatible with the martian environment, it might have gotten a toehold and be The Life on Mars, now.

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 think it would only be possible if there was also lots of water on the planet as well as good solar radiation being close to a star and carbon dioxide. Also it would be helpful if there was nitrogen in the soil since plants absorb nutrients from the soil. There would also need to be rainfall on the planet, but if there wasn't irrigation and watering by caretakers could be sufficient.\n\nAnd what about terraforming? Mars has an atmosphere and I beieve carbon dioxide. Could plants grow on Mars? We'd have to transport millions of gallons of water in our ships and keep the water from sinking deep into the planet. Why would we want to do that? It could cost a trillion dollars. The moon has no atmosphere I'm not sure it could be terraformed. Just a thought.

Yes, but not in the way you might think. I don't think we'll have any of the general population living there at all. (not in 100 yrs anyway). But, I'll bet that a small team of scientists will be living on mars at that time to study and experiment how living on another planet my be accomplished.

Not yet. Organic molecules, considered as precursors to basic life forms, have been found throughout the Universe (mostly in comets, interstellar gas and dust). Experiments show that some bacteria and archaea can survive the severity of outer space. So it's quite possible that we find living organisms in the future, most probably on other planets.

E.\nBecause bacteria can obtain nutrition chemically, they can live in conditions that no-one thought possible, for example in volcanic vents at the bottom of the ocean.

>>> 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.

None that we know of. On earth, there is the right mixture of oxygen, nitrogen, carbon, and other gases that is conductive to our breathing. Mars has different gas mixture which makes our lungs unable to work properly.

Humans do not dominate anything. Bacteria are way more successful than us at surviving, reproducing, colonizing and transforming every tiny corner of Earth's surface, air and water. The Earth contain more bacteria than all other organisms combined. They also fill ourselves: did you know that our bodies host more than 200 species of bacteria and that we couldn't even survive without them?

Extremely possible. To illustrate my answer, I'll refer to the space shuttle Columbia. As we all know it was a disaster, but when scientists examined the debris from space shuttle, they found that bacteria that had been aboard the space shuttle (maybe taken for research purposes) had still survived!! \n\nIf bacteria can survive under such extreme conditions, its entirely possible, that some bacteria could be lodged in a meteorite that could have struck Earth millions of years ago. Also its possible that the same meteorites could have caused bacteria from Earth to travel into space on the dislodged debris from impact. This earth bacteria could possibly do the same thing by evolving into life on a different planet. So its possible that we might meet aliens someday that look very similar to us :)
