Is there life on Mars?
828326
scientists believe there may be life on Mars because Mars have water in its atmosphere. It may only be a small amount, but could provide life to certain living organisms that need very little water

Depends on what type of life you mean. Human life, No. Humans only exist on earth and other space stations where technology has propelled mankind to.

No I believe there is other life out there somewhere. The universe is huge so how could we be the only planet to have life?

i think u asked this Q coz u c some movies say that there r aliens on mars.....no scientific proof  says that there r aliens on mars ...NOT on this galaxy ....Maybe there r other creatures in space...WHO knows!....i hav read many books about aliens on mars but they r stories..just stories

recently probe have been sent to mars to searhc for any signs of organisms or water supplys to suplly evidence that there was life once on mars. So far there have ben pictures sent back showing some sedimentry rocks proving that there was once water on mars, one of the probes landed in a huge crater which was believed to be a lake, since there are signs of water it mean that there must have been  life on mars. Mars wasnt a completly blue planet but there was some water on it, I believe that it was mostly made up of lakes and seas instead of oceans. Btw, the guy who asked to have the best answer, dont do that, you shouldnt demand of of people like that, its the person whos question you answered who decides on who gave him the best answer.

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.

Yes i think they exist, but they are definitely not on mars as people think,their brain is on mars. It doesn't mean that if on mars everything is suitable for a human,these aliens may have other air, food.. that humans don't that we don't know.The extent of the universe is unknown, there may be many of them or even humans that are many light years from us and they cant reach us.

1.) The chances are about 100%, plus-minus 0%. Primitive forms of life (i.e. cells) have been discovered on Mars and on some asteroids, the question is, whether there is intelligent extra-terrestrial life. And I find it hard to believe that there wouldn't be, given the infinite size of the universe and the laws of probability. \n\n2.) No, I don't believe in mermaids. Leprechauns, now that's another story...

Sounds like you already know the answer to your own question...:)  Bottom line:  there is considerable evidence that there was once at least simple life on Mars.  There is some evidence that there may be simple life there now.  There isn't conclusive evidence of either of those things...so if we want to know, we need to keep exploring!

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.

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.

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)

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.

I wouldnt say there isnt any life outsdide our solar system. there can be a very high possibility that there is inteligent life out there.

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!

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.
