I do not think that Mars has any known water at all.
There is very little water on Mars, but some can be found frozen at its North Pole.
There is plenty of water on Mars but only a little on the Moon (maybe in the permanently dark craters).
Earth by far. Mars has very little water and it is only in the form of ice and trace amounts of water vapor. Never in liquid state because Mars does not have enough atmospheric pressure to allow water to be a liquid.
Mars has evidence of minerals that could indicate the presence of past water, but its surface is not muddy like Earth's. The soil on Mars is more like fine grains of sand or dust rather than rich, organic mud.
Neither Venus nor Mars have appreciable amounts of water. Venus is shrouded in dense, poisonous clouds at very high temperatures; Mars has very little atmosphere.
Some tresses of water on mars .So we can say that there is water on mars
The Mars Pathfinder mission provided evidence of past water on Mars through the presence of rounded rocks and sediment deposits on the surface. The rocks were believed to have been shaped by water, implying the presence of liquid water in Mars' past.
mars has flowing water on it
Mars unlike earth is to cold has a little bit of water and oxygen. it cant support human life- but there may be other creatures out there there on planet Mars that it can support . but if humans were there, we would die.
Not presently. There is no permanent liquid water, little atmosphere, and not protection from solar radiation.
Mars has no liquid surface water.
There was water at one time on Mars.
