It is a mixture of the two.
Mars has roughly 30% the surface area of earth. All of that is dry ground. We have only found(very little) ice on mars.
not that we know of, the ice at the poles is mainly frozen Co2, or "dry ice".
Dry ice (frozen carbon dioxide)
Not that we have found, but there are ice caps made of CO2 and water. also, we have found what seem to be dry riverbeds, suggesting that mars once had liquid water and may at one time have been not so different from earth
Winter
It May be possible to live ON Mars as they have found Ice. But Probbebly not IN mars.
the mars rover Spirit found water or ice on Mars
rusted iron and u will never believe this but ICE was found on mars too.
They had found ice on mars but no sign of a liquid
Mars is cold enough for carbon dioxide to solidify at its poles. Earth is too warm for dry ice.
Ice has been found on Mars multiple times through observations made by spacecraft, such as the Mars Reconnaissance Orbiter and the Mars Phoenix Lander. The first confirmed discovery of ice on Mars was in 2002 using data collected by NASA's Odyssey orbiter. Additionally, scientists have also found glaciers, ice caps, and frost on the surface of Mars.
Yes NASA found ICE
