Third Martian Anniversary for Mars Climate Sounder

Posted by David Kass on 2012/05/16 11:35 CDT | 2 comments

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.

Dusty girl

Posted by Emily Lakdawalla on 2012/01/23 05:32 CST

It's near winter solstice in her southern location on Mars, so the angled Sun is not providing as much power as it would in a different season.
