Mars Exploration Rovers Update: Opportunity Emerges from Solar Conjunction to Wrap-Up Work on Matijevic Hill
Sols 3266 - 3295

Posted by A.J.S. Rayl on 2013/05/02 03:15 CDT | 1 comments

As the Mars Exploration Rover (MER) team waited out solar conjunction, Opportunity spent most of April atop the western rim of Endeavour Crater, conducting a chemical analysis of an ancient waterborne vein on Matijevic Hill. It was by the book until the last week of the month when the robot field geologist suffered an electronic "hiccup" known as a warm re-boot, and went into auto mode, a kind of safe mode when something doesn't go right.

Blast from the Past: Spirit's tracks at the "End of the Rainbow"

Posted by Emily Lakdawalla on 2013/04/09 09:05 CDT | 3 comments

Doug Ellison shared this lovely panorama via Twitter over the weekend. It's from the Mars Exploration Rover Spirit, taken back in 2004. The drunken path in the foreground is a visual record of just how exciting it was for Spirit to have finally made it to the Columbia Hills, and to rocks that were not fragments of basalt.

Field Report From Mars: Sols 3237-3262 - March 4–29, 2013

Posted by Larry Crumpler on 2013/03/29 11:27 CDT

Flash memory or computer problems oddly occurred on both Curiosity and Opportunity around Feb 27. One possibility is that a large solar flare resulted in radiation at Mars sufficient to temporarily corrupt the memory on both rovers.

Will comet Siding Spring make a meteor shower on Mars?

Posted by Emily Lakdawalla on 2013/03/05 04:34 CST | 6 comments

JPL's Solar System Dynamics group shows that there is still a possibility that C/2013 A1 (Siding Spring) could hit Mars. But the uncertainty in its position at that time is large -- the closest approach could happen an hour earlier, or an hour later -- so we're a long way from knowing yet whether it will or (more likely) won't impact.
