The water is frozen. That's the only thing they know at the moment.
Yes but only in the solid form - ice.
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.
There was water at one time on Mars.
The temperature on Mars is too cold for water to exist in liquid form on its surface.
Yes, water is present on Mars in the form of ice. There are polar ice caps on Mars that consist of water ice and observations suggest the presence of subsurface water ice as well. Additionally, liquid water may exist temporarily in some regions on the surface.
in the poles
Water cannot exist in liquid form on Mars and the outer planets because of their extremely low temperatures. Mars has a thin atmosphere that cannot trap enough heat for liquid water to exist on its surface. The outer planets, like Jupiter and Saturn, have such low temperatures that water freezes into solid ice or exists as vapor in their atmospheres.
Water on Mars exists in the form of ice at the polar ice caps and subsurface ice deposits. Some liquid water may also exist temporarily during certain seasons or in specific locations, but it quickly evaporates or freezes due to the low atmospheric pressure and temperatures on the planet.
Mars' atmospheric presure is 1/100th of earths. Beacause of this extremely low pressure, water can't exist on Mars in its liquid form because it boils instantly
There is no liquid water now on Mars. There may have been, in the past. Also, there is ice on Mars.
Testing by probes that have been sent to Mars indicate that water does exist.
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?
