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.

Notes from Titan talks at the 2012 Lunar and Planetary Science Conference (LPSC)

Posted by Emily Lakdawalla on 2012/03/20 02:16 CDT

One of the topics I found most exciting yesterday was a series of talks on Titan's climate. Bob West showed how Titan's detached haze has shifted with time. Zibi Turtle presented about how Titan's weather has changed with these seasonal changes. Jason Barnes followed up Zibi's talk -- which was based on Cassini camera images -- with a study of the same regions using data from Cassini's imaging spectrometer, trying to figure out what was going on with that brightening. Ralph Lorenz talked about rainfall rates on Titan. Jeff Moore asked: what if Titan hasn't always had a thick atmosphere?
