re: Ice Crater flyover video
Thanks, guys......BRFelix, good points. I'd guess that at some point the entire crater was filled with ice. At some time in the past and for a certain period of time, the tilt of Mars axis may have been such that enough solar radiation was received at these latitudes to allow a large portion of the ice to melt away.
ET.......I've saved all the Mars Express perspective photos released and would like to think I'll animate all of them eventually, including the Olympus Mons series.......goddamn day job seems to get in the way of everything though! ;)
