Because the atmosphereic pressure is too low.
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.
Water exists on Mars in the form of ice, primarily in the polar ice caps and underground. There is also evidence of water vapor in the atmosphere and sporadic liquid water on the planet's surface in the form of brines.
in the poles
Water on Mars exists primarily in the form of ice, found in polar ice caps, underground ice deposits, and frost on the surface. There is also evidence of briny water flows or seasonal liquid water on the surface in some regions during certain times.
Currently, Mars is too cold for liquid water to exist on its surface. Dry river beds suggest that liquid water once flowed there.
Mars is a planet that is too cold for liquid water to exist on its surface. Almost the entire surface of Mars is covered in ice.
liquid water cerrently on the surface
Mainly at the poles,but also scattered throught the planet's surface
The temperature on Mars is too cold for water to exist in liquid form on its surface.
There was water at one time on Mars.
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.

Mars has no liquid surface water.
