what happen to the water , why is mars all dried up now , studies show they had water millions of years ago....gee i hope it wasnt global warming ...

Partly frozen, partly went off into space because of lesser gravity, partly underground.

Most scientist today think that if indeed there was ever any liquid water on the surface of Mars it would have been lost to space long ago. Mars does not have as powerful a magnetic field as does Earth does and is affected by solar wind to a far greater degree.
Mars is not as large as Earth, is farther from the sun obviously, and has a very thin atmospheer composed mostly of carbon dioxide.
A warm day on Mars is like a mild winter day in New England in winter. At night the temperature drops to below zero. Living on Mars would like living in Antarctica without all the ice and snow.

The greater we seek for water on different planets... the greater we detect it. seems to be water everywhere. On planets that are smaller, or nearer to the solar, there is the undertaking of dissociation: the water molecule H - O - H could be split particularly actually with the aid of extremely-violet gentle. The solar places out a super number of extremely-violet gentle, so as that water molecules finally end up being split into hydrogen and oxygen. The hydrogen (being very gentle) escapes to area. Oxygen effectively combines with different stuff (the exterior of Mars is crimson because of the fact it somewhat is oftentimes rust - the oxygen having blended with iron and different atoms). on the earth, we've an ozone layer that protects us from UV rays, and we've a magnetic field that protects us from charged debris from the photograph voltaic wind (they'd have an analogous effect). So, we've been given to maintain quite a number of our water, even as the different inner planets misplaced quite a number of it. nonetheless, we even chanced on water (underground, close to the poles) on Mercury.

Most of it got "destroyed" by solarradiation. UV rays can split water into oxygen and hydrogen. The oxygen reacted with other molecules and with the soil while the hydrogen was able to achieve escape energy and was swept into space. Same thing happened to Venus water except Mars is cold enough to retain some water as ice.

global cooling on mars :) it's colder then earth! :)
the water drained away and became underground ice :) http://science.nasa.gov/headlines/y2002/28may_marsice.htm
not to say that it is getting colder on earth, 20 years ago headlines in the paper said an ice-age is coming! global warming, means 1 degree over the next 100 years... I wouldnt mind it being a bit warmer, Im installing pink batts insulation in my house as im so cold! :)

Its still there--we know that much of the South Polar martian icecap (up to 2 miles thick) is water. And there are subsurface deposits of ice as well--which appear to be extensive all over Mars, though that hasn't been confirmed yet.

the atmosphere is too thin to hold the water. as a result, the water gets exposed to space and freezes because of the temperature which is below 0C...

mars's atmosphere disappeared, allowing the sun to have more harmful effects, allowing all the water to vanish
