Scientists have long theorized that Mars once had an atmosphere and surface water–but where did it go? This video showcases one of their theories about Mars’ vanished water reserves.

When you take a look at Mars, you probably wouldn’t think that it looks like a nice place to live. It’s dry, it’s dusty, and there’s practically no atmosphere. But some scientists think that Mars may have once looked like a much nicer place to live, with a thicker atmosphere, cloudy skies, and possibly even liquid water flowing over the surface. So how do you go from something like this–to something like this? NASA’s MAVEN spacecraft will give us a clearer idea of how Mars lost its atmosphere, and scientists think that several processes have had an impact.
