If the two polar ice caps on Mars' surface were to be melted, it would release enough water to cover the entire planet with approximately 11 meters of water.
There is ice beneath the surface of Mara and at its polar caps. The atmosphere contains small amounts of oxygen.
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
The robots sent to Mars have found Water Ice in large quantities on the surface of Mars.
Large quantities of water ice close to the surface
Mars is to cold to have water. Plus its atmosphere is to thin. Yes, but Mars does seem to have water ice at its poles. Also there is probably water under the surface, again in the form of ice.

Some do. Earth is the only planet known to have liquid water. Mars has ice at its poles and beneath its surface in some places.

Yes, there has been enormous quantities of ice discovered just under the surface of Mars as of 2002.
Venus: Not much at all. Mars : Quite a bit in the form of ice, near the poles. Also probably some under the surface.

There is no liquid water on Mars. Ice is present at the polar ice caps and in some places below the surface sediment.
the surface on jupiter is that it has no surface at all
No. For two reasons: # The temperature on the Martian surface is less than 0 Celsius and thus any water (to form a swamp) would be in the form of ice and therefore solid. # The atmospheric pressure on Mars is so low that water can not exist at the surface. If you place a lump of ice on Mars and heated it, it would go straight form solid Ice to water vapor. Thus this again means that there can be no water on the surface of mars with which to form a wet swamp. However, having said this please understand that there is H2O on Mars in the form of ICE and water vapor - we do not know how much H2O there is at the moment and we believe that there was quite allot of liquid water on Mars' surface in the ancient past.
Mars and Earth.

There are a few planets which have ice. Earth has ice. Mars is believed to contain ice far underneath its surface. Pluto which is no longer classified as a planet has a surface which is completely frozen.
