is there any life in mars?

So far there is no firm evidence of any life on Mars. Most of the results are meticulous speculations.

1.  On Mars, yes.  It's only microscopic life though.  Sedna, I have no clue.\n\n2.  Go here.  It'll provide a great answer to your question.  http://www.pbs.org/wgbh/nova/sciencenow/3210/01.html

It's completely beyond our current science and technology to replicate the environment of Mars with such precision that we could be confident that we'd have the exact same (or even similar) conditions for life as exist on Mars.\n\nIn addition, how would we replicate Mars' environment when we know so little about it?  You'd need to send thousands of probes to Mars to get enough information to even *begin* such an experiment ... and by the time you'd finish that, you could've already run a full set of experiments on Mars testing directly for the past or present existence of native life forms.\n\nA planet's biosphere is an incredibly complicated thing.  It's something that scientists seem to only now be learning about our own biosphere, unfortunately a bit too late.

Humans will probably live on Mars at some point, though it would probably be only temporary.  Now let's look at the problems.\nThe biggest problem would be making Mars a suitable environment for human life.  Terraforming the planet to give it a similar atmosphere as Earth would take thousands of years, if not longer.  The other option would be to build colonies.  And even then there's the question of what to do about gravity.  Because the gravity on Mars is less than that of Earth humans would have a difficult time maintaining muscle mass and bone density.  So, some sort of solution would need to be found.\nNext, let's face it, Mars is terribly far away and has little to offer, except maybe some frozen water.  And being so far away from Earth would probably be very problematic.  It is much more likely that in the future, if humans are to live in space, they'll live in self-sustained space colonies orbiting the Earth.

Yes, I fully believe there is life on other planets.  What it took to create life on Earth was not favored to happen.  The odds that Earth would hold any life at all are too small to comprehend.  But we do not know how large the universe is.  We do know that there are trillions of planets, trillions of galaxies, trillions of stars.  The odds that there is not a speck of life on any of those planets is also extremely small.\n\nI must admit that I have seen a UFO, which occurred last year.  I was driving my friends home from a party and I happen to look in the sky to see a bright white diamond-shaped object.  There were four individual diamond lights that made up the overall shape.  I was astounded, and I knew it was not anything that the United States had admitted to having.  I could name every military jet, helicopter, blimp, and passanger aircraft that I see, but I could not for the life of me figure out what it was.  I immediately turned around and drove to follow it.  Within five-ten seconds, the craft had flown so fast that the lights had disappeared (I watched it the entire time).  I'm not saying it was extra-terrestrial, but it was a UFO.  I live in Cleveland, by the way.

Over the years we've sent quite a few probes - both orbiters and landers - to Mars.  So far we have seen zero signs of intelligent life, and nothing definitive about simple life, either.\n\nWhat we have seen that excites us is signs of water.  And from what we know about biochemistry, it may be pretty easy for simple life forms to develop in the presence of water.  Some of the probes that have landed on Mars have looked for organic compounds - the building blocks of life.  So far they haven't found anything like that - but that doesn't mean they're not there!\n\nI think the best way to investigate if there's life on Mars would be to send humans there to to really good tests.  Hopefully that will happen in the next 15 or 20 years.

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.

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).

having life only exist on earth is like picking up a single grain of sand and saying that that grain was the most perfect grain in the entire world...it would be impossible to know this unless every other grain was examined, and the fact the new grains are constantly being made.  there are over 200 billion galaxies in the visible universe and a couple hundred billion more out there, all containing stars and planets that maybe able to sustain life.  and by "life" that also takes into account of any micro-organisms like bacteria and viruses and any other forms of life that might exist.  So to say that there is no life on other planets would be incorrect to assume, it's just a matter of time in trying to find it, whether it exists in our solar system is still debatable as micro-organisms can live in harsher conditions that larger organisms arent able to

Of course I think life exists!  Infact, I beleive there is life in the solar system.  How do we know if there isnt life floating in the clouds of a gas giant, or icy crystal like things on pluito?  We havent searched hard enough for these yet!  Duh!\n\nLife outside of the solar system might be a little hard, considering that there are only "hold jupiturs," and "frozen earths."  Both are to hot or cold to support life, and they are massive and have insane gravity.  However certain single celled organisms, say bacteria or such, might reside on the planet.  I always thought that might be.\n\nIn addition, Europa, a moon of Jupitur, has ice flows on it that scientists think liquid water might reside under!  It might be interesting to see what could live there.  From the means of life there, I came up with a skating green creature who could move around on the ice, absorb the moisutre of the water, and undergo photosynthesis to obtain energy.  \n\nEnjoy!\n\nNote: I do beleive in aliens, but dont beleive in UFOs.  Considering how many hot jupiturs there are, I dont think we will even see any life as smart as we were as cavemen until alot later in time...

The only clues to life on Mars are that it once had water, and there may be water beneath the surface in which some kind of primitive life might have survived from Mars watery period.  \n\nSome water ice also forms at the poles, and may harbor some primitive lifeforms that respond to the seasons.  But no probe has been there to do the study.\n\nThere is still a lot of debate regarding the Mars meteorites and whether they actually contain microbes.  Firstly, they may not be fossilised microbes at all, and secondly you have to show clearly that the meteorites have not been infected by Earth microbes. \n\nSo, nobody to date can say with any certaintly that life exists anywhere else but on Earth.\n\nFood for thought.

are you living in Mars??

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

there hasn't been any found yet.... but... the possibility of life on other planets is very  high....  :)

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.

if theres not i would be extreme surprised.  the universe is so huge that it would be ridiculos to assume or think there isnt.  even though we have only explored probably less then 1% of the universe we have still found planets that we think would be able to suport human life (remember not all life would have to be carbon based like us either) so even if there isnt a planet that we could live on some other type of creature might think its paradise.  the answer to your question is yes there is most likely life other then ours out there somewhere. although it would depend on what you mean by "life" if you mean intelligent life i still think yes there probably is although they have found fossils of bacteria on mars so technically that means there was at one point there was life in our solar system other then earth.
