Is there life on mars?

10 Answers
People have long speculated about the possibility of life on Mars, and meteorites have been found that have been rumoured to indicate life exists on Mars. Is there any concrete evidnece for life on Mars?

There is no concrete evidence for life on Mars, but based on the findings of the NASA "Curiosity" rover, parts of Mars have indeed been deemed habitable. Just because the environment and atmosphere there is not habitable for human life does not mean it is uninhabitable for simpler life forms. NASA is convinced enough that life may have at one time been present on Mars that in 2020 it will send up a rover which, unlike Curiosity, is specifically designed to search for what they refer to as "biosignatures" -- evidence that life did at one time exist there.

Life on Mars will clearly be vastly different from life as we know it. I suspect that organisms on par with the complexity level (aka, simplicity level) of bacteria or prions -- maybe even a very exciting fungus -- have been present there. Organisms evolve and adapt based on the environment at hand; it wouldn't surprise me at all if single-celled creatures had, at some point, existed on the "Red Planet" and were specifically adapted to the unique, harsh environment there.

The core of Mars has stopped spinning billions of years ago, so mars doesn't have a magnetosphere. Sense mars doesn't have a magnetosphere, there is not much protection from the suns radiation. It is unlikely because of this, that any life could survive on the surface of Mars. But it is possible, that if there was life their in the past, maybe it has evolved to live under ground or in the ice regions of mars. But then again, bacteria has been proven to be able to survive the harshest regions on earth, like the bottom of the ocean. So it is still possible, that life exists..:)

It seems clear that the environment on mars is not suited for life, but the whole planet there hasn't exactly been fully explored, perhaps there was once some life forms there; but we don't know yet. It is a possibility and I think that it will keep being explored, but we won't know soon, because it is a big planet, just have to wait and see, what else can we do?

In my opinion, It probably existed years, decades, centuries even milleniums ago. But now, It's all dry and dead. Only ground, mountains hill and other stuff. But I don't think there is anything living on there. If there is, the species are probably hiding underground in caverns or so, because there aren't many things that would help you survive on the surface.

I do believe that some form of life did exist on Mars at one stage, Is there life there now we just dont no.

Maybe there is some form of life there nw. Just because we cant breath the atmosphere don't mean the other form of life can't. Im guessing further study is needed to no for sure by the worlds different space agencies.

If life ever existed on Mars, I don't believe it exists there at all now. I am terribly skeptical that it ever existed on Mars. If and when we do discover life on another planet, I believe it will be outside of our solar system. It will be a planet far away, probably orbiting a star similar to the sun in our solar system.

Unless every square inch of the planet has be explored, we will never know. It would be ironic that there are millions or billions of life forms in Mars and the very small number of robots we send there keep missing communities of life.

No, there's no life on Mars as of now. Mars is uninhabitable, and too far from the sun to live there. Mars is nothing like earth where you don't need spacesuits to go outside. On Mars you need spacesuits to go outside.

I don't think so, but the robot "curiosity" of NASA, will give us the answer very soon.

No, there's no life on Mars, it's uninhabitable, so nothing would survive in that atmosphere.
