Blue, Not Red: Did Ancient Mars Look Like This? Is that Earth? Nope! That’s Mars… well, it might’ve been Mars a couple of billion years ago when it had a thick atmosphere and oceans (yes, oceans). Although the inclusion of a Martian biosphere (the green bits) is a little, well, fanciful, software engineer Kevin Gill used real elevation data from NASA’s Mars Reconnaissance Obiter (MRO) to render the planet and then added water and an atmosphere (and a touch of green for some hypothetical Martian vegetation). 

"I am a software engineer by trade and certainly not a planetary scientist, so most of my assumptions were based on simply comparing the Mars terrain to similar features here on Earth (e.g. elevation, proximity to bodies of water, physical features, geographical position, etc) and then using the corresponding textures from the Blue Marble images," Gill told Discovery News.

To be honest Kevin, we think you did an awesome job.
