May 16, 2012 is the third martian anniversary of the start of Mars Climate Sounder (MCS) observations from Mars Reconnaissance Orbiter. MCS started measuring the atmosphere of Mars three Mars years ago, on September 24, 2006. We can now compare the weather and behavior of the atmosphere in three different years, and find the temperature differences to be surprisingly large.

False color Landsat 5 image used by Max Rocca, supported by The Planetary Society, to discover the Rio Vichada Impact Structure, which, though still awaiting final confirmation, appears to be the largest impact structure in South America with an outer ring at 50 km and an inner ring at 30 km diameter. Note the course of the Rio Vichada river in the image which flows around the highly circular structure in the center.
