Is there life on Mars?

"NOVA" online has a wide range of material on the topic. Read Twitter feeds from Phoenix, the rovers and the Mars Science Lab; see incredible images of the surface of Mars; explore the anatomy of a rover; and find out what it was like to film alongside one.
For more on the Mars missions, check out this NASA website.
So, where do you stand: Do you think there is life on Mars? Cast your vote in our online poll and let us know what you think. Comments from skeptics most welcome.
If you miss tonight's "NOVA," you can watch the full episode (and others) online at pbs.org/wgbh/nova/.

I do believe that there is life on Mars although microscopic now. I do believe that at one time, or in the future through
colonization or evolution there may be again.

There is "not" the type of life that could suport human colonization. I think colonization of Mars is impractical and not cost effective. Man needs an "earth like" planet
to colonize. I am positive that there is such a planet.

It is good to know, for certain, that there is water on Mars and that conditions could exist to support life. The Phoenix mission is the first to verify that information. Most scientists know that our Sun will someday grow and make life on earth untenable. We, as the human race, will have to colonize and terra-form Mars if we are to survive as a species. Mars is the next logical stepping stone towards, what may become, a colonization of our solar system and, perhaps, beyond. Thank you Phoenix...

Why is the discussion about "life" on Mars (or anywhere really) always water-based human form? Are we humans so naive (or stupid, actually pompous) to really believe life can only exist in our "form"?

Robert is right, colonization of Mars is not cost effective in the forseeable future. Colonization should be through Space Stations built from materials on the asteroids, Jovan moons and our moon. The stations could be large enough to spin for gravity and be multifuntional. Mankind needs to master space itself, not just another planet.

Now that we know there is water on Mars, should we send a tera-forming experiment? Designs exist for science stations that could stage an inflatable biosphere where on site experiments can be made to generate oxygen and create an atmosphere. Problem is it would have to be set up near water, which seems to be concentrated at the poles where, there is less light, hence less power and a harsher climate.
It would cost upwards of $2B dollars to do it right, a small (Micro-sat) short term test could be done for as little as $400-$600M or maybe less.
Do you think we should send an experiment of this type to Mars??

There is no life on Mars. There won't be life on Mars. And we should not send people to Mars.

If there is any life on Mars it came from Earth. Either we accidently brought it or microbes in the upper atmosphere were blown to Mars by the solar wind. I do not believe it originated on its own. I would like to see us explore Mars and establish a colony if that's possible.

if there were life on mars man would have already found a way to exploit it and if possible make money from it. the liberals would be clammering to extend social services and to pass some kind of amnesty for (it), (them), just in case something or someone found its way through our impenetrable border security. we may want to consider looking for life real hard though, because it could mean another source of tax revenue. GOD help the creatures of distant planets if earthlings ever get to them.
