I’ve been reading Red Mars by Kim Stanley Robinson. I’m about 1/3 of the way through it and so far it gets about 3.5 out of 5 stars. I’ve always been fascinated by Mars and have fantasized about visiting it.
Anyway, reading the book got me interested in looking up some good images of Mars so I could “see” where some of the events of the book take place. While doing that I discovered Kevin Gill’s awesome work at using Mars Global Surveyor detailed topographic data to extrapolate what a “Living Mars” might look like. He picked a “sea level” height based both on what looked right from the topography, and that exposed coastlines or features he liked the best. He then rendered multiple images of it. Eventually he rendered this 3D animation of this living Mars’ rotation. VERY COOL!
