Is there Life on Mars?

I think the question of whether there is life on Mars is still open, answered. The conditions on the planet are incredibly hostile, so the chances we'll find life there are quite small, but not zero.

The fact is, we're only just now beginning to discover how life on earth has somehow survived incredibly hostile conditions as well. Scientists in California have just recently found bacteria, and algae, still alive after being sealed for 34,000 years in salt crystals.

In South Africa, another type of bacteria has been found happily living two miles deep in the earth, in colonies which apparently take energy from the decay of radioactive rock, rather than sunlight. Scientists estimate these microbes have been isolated for several million years from earth's surface.

Mars did have an atmosphere, and water at one time, and conditions which could have supported life on or near the surface. It's not at all impossible that as the Martian atmosphere was slowly lost to space, life forms didn't find safe haven, or adapt, to survive beneath the surface.

I believe yes! I don't mean people and cities, but "life" Methane geysers have been apparently recorded coming from the surface of Mars.Methane is important because something like 90% of all earth methane came from biological sources of one type or another.There are most likely in my mind ..bacteria of one type or another previously unseen trapped in the polar ice on Mars. Just like we can find , and have found here on Earth. Also I feel it is important to point out that "life" may not be initially recognizable to us when we see it, as we may be expecting to see Earth type lifeforms when in fact they could be well.. anything..

The question is still open ended. Life on Earth somewhat proves that life forms will adapt to changing conditions when the change is gradual. We have found life forms here that have adapted to survive in an environment that we previously thought impossible. For instance, algae (?) that lives in temperatures at, or above, the boiling point of water and in water with a pH levels that life as we knew it, couldn't survive in. Mars' environment didn't change overnight. Although any complex life forms may have died out, simpler life forms may have adapted to the current conditions on Mars. We just haven't found them yet.

Possibly in the past. Mars is a dead planet from what I can see through science. A weak carbon dioxide atmosphere really would not support much unless it was some sort of microbe.. that is of course assuming that life there is water based.

Too many people just assume life is water based, I bet there's an alien out there somewhere who drinks a cup of sulpher when he's thirsty..

I'm willing to bet that life exists, or more likely, used to exist on Mars in some fashion. Probably not any complex organisms, but possibly some simple microbes at least. Just look at some of the hostile conditions on Earth where life exists.

Maybe, scientist believe that water was once flow in the past. Water is the main ingredient of life, so if ever life will be found on Mars it would be a fossil to say the least. At least it exist in the past.

They haven't confirmed that there is life on mars, but in my honest opinion, I don't think they know anything about the subject.

They are sending new rovers up this year, with lasers to try to break through the ice, The rover should arrive late in 2012

I don't know if there's really life on mars, but Life on Mars made two really good television shows.

No, but I did see some sailors fighting in the dance hall...
