Blue, Not Red: Did Ancient Mars Look Like This? 75

astroengine writes "Using elevation data from NASA's Mars Reconnaissance Orbiter, software engineer Kevin Gill was inspired to create a virtual version of the red planet with a difference. 'I had been doing similar models of Earth and have seen attempts by others of showing life on Mars, so I figured I'd give it a go,' Gill told Discovery News. 'It was a good way to learn about the planet, be creative and improve the software I was rendering it in.' He included oceans, lakes, clouds and a biosphere — a view of a hypothetical ancient Mars that looks wonderfully like home."

    It is an interesting exercise.
    But I notice the renderings show a lot of nicely circular lakes, suggesting meteor impact craters. If Mars at any time had this amount of water and a thicker atmosphere there would likely be less craters and those that did remain would probably have different shapes due to erosion. It would suggest the meteorite impacts happened after the water evaporated and the atmosphere thinned.

Nothing happens.
