From high above. Gorgeous.
If you look closely, you'll see dozens of black, spidery-looking things in these photos. They aren't Martian arachnids (obviously), but something equally as interesting. It is now believed they are carbon dioxide geysers, the dark color coming from the darker underlying dirt and particulate matter that's being spewed into the atmosphere during the spring thaw near Mars' south pole. Scientists aren't certain this is what's happening because nothing like this is seen on any other terrestrial planet, but based on the evidence it seems to be the most likely explanation.
