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.

The latest HiRISE view of Opportunity, on Endeavour's rim

Posted by Emily Lakdawalla on 2011/09/24 10:19 CDT

In a now-routine act of obtaining detailed photographs of robots from Earth sitting on the surface of another planet, the HiRISE camera on Mars Reconnaissance Orbiter has captured a view of Opportunity sitting on the rim of Endeavour crater.

Gale's not the only Martian crater with an "enigmatic mound"

Posted by Emily Lakdawalla on 2011/08/17 07:33 CDT

Much has been made of the "enigmatic mound" within Gale crater, which will be the target of the Curiosity Mars rover's investigations. The 5,000-meter-thick section rocks in Gale's central mound will be fascinating to study, but the fact that Gale has a central mound that's taller than its rim is not at all unusual on Mars.

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.

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.
