Heres a couple of the main contributing factors; Only dealing with the surface of Mars!and no referance to its polar region!
The atmosphere on mars is to thin to sustain liqiud water and is continuously bombarded by cosmic rays such as UV rays and inturn has sterlized the surface of the Planet.
the loss of its atmosphere has been stripped away by solar storms; bombardment of metorite impacts plus volcanic expolsion from Mars itself in its tutbulent past. The Martian atmosphere lacks an ozone layer for protection.
Example H2O, liquid water is the prime ingredients for life as we know it. and as liquid water isn't present on Mars - at the surface anyway this can be elimanated, and if any found its way to the surface it would dissacociate (spelt this wrong ).
H2O: where the hydrogen would be lost to space - most of it anyway because of its light weight and most of the oxygen is oxidised into the soil - hence its redness more complicated than this, but gives the basics anyway.
So far, scientists, who are still hoping, are turning up empty handed on the "life on Mars" subject. There is currently no evidence of life on Mars.
yes
Life as we know it would likely not exist on Mars due to its thin atmosphere, lack of liquid water, and intense radiation. However, if Mars had a thicker atmosphere, more stable climate, and liquid water on its surface, there would be a greater potential for life to exist.
ahmm.... yEah ! there is... but for now.., , , for me ! . there's no more life in Mars... Life would not exist there anymore !! MELOVESYOU !! TEACHER KIRA ! .....
well...... we can't say yes but also not, if NASA ever launch a manned mission to mars might simple plants can be seeded and might be the start of life on mars and if the NASA did not launch a manned mission to mars might be not but human civilization can survive on mars so if earth ends mars should be seeded with life because it contain all condition for life to exist and in these day one more way of life on mars NASA spacecraft can can increase green house effect on mars so with these if it rain on mars than anyway there can bacteria exist and other life forms
can life exist on mars
Life has never been proven to exist on Mars.
It is becoming more and more likely that life will exist on mars. This is because mars has many quality's that the earth has. It is possible, that in a a few million years (although this is not by any means definite) that life will fully exist on mars.
The temperature on Mars is too cold for water to exist in liquid form on its surface.
There is no reason why a form of life doesn't exist on Mars. If life can exist in the very hot thermal vents deep in the earth's oceans, then why life in some form can't exist on another planet in some form?
No life is known to exist there. It is too cold, too dry, and there is very little atmosphere.
So far, scientists, who are still hoping, are turning up empty handed on the "life on Mars" subject. There is currently no evidence of life on Mars.
Since life as we know it requires water, scienctists hypothesize that Mars may have once had the conditions needed for life to exist.
No, as of yet there is no evidence of any life existing on Mars but they are still looking.

Because Mars is the closest planet to Earth
