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.
A recently published paper proposes that much of the sedimentary rock on Mars formed during rare, brief periods of very slight wetness under melting snow.
Виталий Егоров (Vitaliy Egorov) is a Russian space enthusiast who enlisted help of fellow enthusiasts to search for -- and maybe find -- the Russian Mars 3 hardware on the Martian surface. Here he explains how he did it.
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.
As the Mars Exploration Rover (MER) mission trekked further into its tenth year of exploring the Red Planet, Opportunity spent the month of March finishing up its science investigations on Matijevic Hill.

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.
Curiosity is back to science operations, though the activities are limited in scope by the fact that conjunction is fast approaching. Here's a couple of neat images from sol 227.
A mind-boggling quantity of information is being presented at the Lunar and Planetary Science Conference. In my first report from the meeting, I try to make sense of the Curiosity and Opportunity sessions.
The news from the Curiosity mission today is this: Curiosity has found, at the site called John Klein, a rock that contains evidence for a past environment that would have been suitable for Earth-like microorganisms.
Planetary Society Hangout: March 7th, 2013 - What's Going On With Curiosity and a NASA Budget Update
Thursday at noon PST/3pm EST/20:00 UT
Thursday at noon PST/3pm EST/20:00 UT we check in with Emily Lakdawalla to bring us up to speed with Curiosity's computer problems and we check in on NASA's budget status.
As February turned to March, Opportunity was conducting some of its final science investigations on Matijevic Hill, the MER team was making preparations for the robot field geologist's trek south for the next winter, and the Mars Exploration Rovers mission was checking off another month of exploration.
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.
