At the poles, and (believed to be) under the cryosphere.
No, it cant mars is too cold so you can only be in the form of ice
Water exists in its solid state in the ice caps. It is believed that liquid water exists beneath the surface. Formation of carbonates -Including globules
Many speculated about the presence of liquid water and rusted iron on the planet's surface.
There is plenty of water on Mars but only a little on the Moon (maybe in the permanently dark craters).
there are river beds which must have Bean carved by water
The intention of most of the missions to Mars was to learn more about the mineral composition of the surface. Namely, if water exists or did exists, and whether lifeforms were ever present.
Scientist believe that the planet Mars used to have flowing liquid water. Now, the water on Mars exists almost exclusively as ice.
Yes, only one planet Mars exists.
Water is abundant in space, the problem is rather that was the water exist in significant amount on any particulars planet.
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.
Scientists believe that the water on Mars exists primarily as ice, particularly in the polar ice caps and beneath the surface. There are also signs of transient liquid water in the form of briny flows, but these are less common. The detection of hydrated minerals suggests that water once flowed on the Martian surface, indicating a more dynamic water history in the past. Overall, while liquid water is scarce today, evidence supports that Mars has a significant amount of water in various states.
Mars still exists. It is about 4.6 billion years old.
