Explanation: What's causing seasonal dark spots (http://themis.asu.edu/images/subpage/news/polar_2) on Mars? Every spring, strange dark spots (http://antwrp.gsfc.nasa.gov/apod/ap040831.html) appear near the Martian poles, and then vanish a few months later. These spots typically span 50 meters across and appear fan (http://en.wikipedia.org/wiki/Fan_%28implement%29) shaped. Recent observations made with THEMIS (http://themis.asu.edu/about) instrument onboard NASA's Mars Odyssey (http://mars.jpl.nasa.gov/odyssey/mission/), currently orbiting Mars (http://antwrp.gsfc.nasa.gov/apod/ap060730.html)
