No one knows for sure, but scientists think since mars doesn't have much of an atmosphere, so the suns rays were directly going into the planet, so that soaked up the water. But the water cycle doesn't work the same way as it does on mars than earth, so it didn't ever rain water, just methane and other gases.
its all red
We don't even if Mars had water, but if it did the water would've been "absorbed" into the planet like a giant sponge.
Mars Rising happened in 1997.
Monuments of Mars happened in 1991.
Caverns of Mars happened in 1981.
Mars Cars happened in 1982.
Mars Saga happened in 1988.
What happened to the water on mars h'm its simple really. A long time ago about 10000 million million years ago mars had water all over its surface in seas and oceans like earth. But one day a giant solar flare burst-ed out of the sun straight at mars. Mars had a ozone to protect but not as strong as earths. The solar flare made the ozone layer evaporate and evaporated all the water mars had ever had except for the polar ice caps. Then mars became a dirt land of nothing. Mars had water but probably never will again.
Some tresses of water on mars .So we can say that there is water on mars
That is a good question. Currently, the best explanation is that, as Mars cooled, the water froze and was eventually buried under ground by dust storms where it might still exist.
a lot happen new in mars, buddy
mars has flowing water on it
