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.

Nighttime Water Ice Clouds Predicted by Models are Confirmed by MCS Observations

Posted by Jim Shirley on 2011/10/25 12:00 CDT

A daily cycle of cloud formation in the Martian tropics during northern summer is driven largely by solar radiation and the associated solar thermal tide. Models predict a striking pattern of cloud formation above the high altitude volcanoes of the Tharsis region. At mid-day, the atmosphere is typically free of clouds due to elevated temperatures. Beginning in the early evening hours, atmospheric cooling at altitudes above 20 kilometers begins to foster water ice cloud formation. During the night, the altitude of cloud formation descends closer to the surface.

What's up in the solar system in April 2011

Posted by Emily Lakdawalla on 2011/03/31 03:59 CDT

April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.

What's up in the solar system in March 2011

Posted by Emily Lakdawalla on 2011/02/28 02:43 CST

I don't think there's any question what the big event of this month will be: MESSENGER is finally, finally entering orbit at Mercury on March 18 at 00:45 UTC (March 17 at 16:45 for me).

Scientific clarification: "inverted topography" is more general than "esker-like features"

Posted by Emily Lakdawalla on 2011/01/14 10:50 CST

In the past couple of months I've received several emails from scientists offering clarifications, corrections, or alternative points of view to previous posts, which is awesome and something that I enthusiastically encourage. Here's one of them.
