I know it’s been all Curiosity, all the time on this blog for the last couple of weeks, and that’s not likely to change much for the next couple of weeks. But I don’t want people to forget that there’s another rover exploring Mars’ ancient geology. Opportunity has been taking spectacular photos of Whim Creek and Endeavour Crater this last week.

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.

As winter began to retreat in the southern hemisphere of the Red Planet, Opportunity was commanded to finish up her science assignments in April in preparation for leaving its refuge, and the Mars Exploration Rover mission rolled through its 100th month of exploration.
