This article seems to suggest that it partly evaporated into space:
http://news.yahoo.com/s/space/20070613/sc_space/mysterysolvedmarshadlargeoceans
Why?
Why doesn't it happen here on earth?
Wouldn't gravity on Mars keep the moisture on the planet if it is even able to maintain a thin atmosphere?
The idea of turning to ice, migrating, being covered by a crust is all logical, but to me, evaporation is not.
Please help me understand this.

It's TICK TICK TICK Butterfly. You're so Brittish.

Hi, Mars does not have a atmosphere that is like ours. Also their position in our solar system means that they are farther from the sun. There for it is a ice planet. They suggested at the end of the article that there may still be something deep, deep underneath the surface of mars. For the most part yes it evaporated, but I think its mostly from their atmosphere. See our atmosphere contains oxygen, nitrogen, and about 1% of varis gases. It has a better capability of keeping moisture in, also the water cycle helps to keep water here on Earth, Mars because of it's freezeing tempatures could not do this and so it just evaporated.

technological know-how fiction at its maximum suitable is analyzing issues that are consistent with the guidelines of physics as all of us understand them, and projecting issues that could conceivably take place. Greg undergo's Mars sequence examined the opportunity of terraforming Mars. In those books, they further an ecosystem over many years utilizing bioengineered existence varieties. i think of it extremely is a plausible issue. we would have the biotechnology as we communicate to offer bacteria able to doing something like that, yet they additionally could be waiting to proceed to exist and thrive in the Martian ecosystem. i'm uncertain what that would take, yet i might think of the type of factor is under 50 years far off from threat.

I didnt read the article but it is possible since Mars really doesn't (and from what i know hasn't) had a substantial atmosphere partially because the gravity there is much smaller than on earth. btw the title of that article is very misleading...it has not been proven that there was water on Mars just one heck of a lot of evidence for it.

The reason is the lack of a magnetic field. If ours goes away, so will our oceans. It would be basically, in layman's terms, blown away by the solar wind.
