For most of April, while Mars scuttled behind the Sun as seen from Earth, both Mars rovers were pretty inactive. Now that conjunction has ended, both are doing what rovers should be doing: roving and exploring. As of sol 3312 Opportunity had moved more than 300 meters southward toward Solander Point, while on her sol 279 Curiosity drilled at a second site, Cumberland.
Last month, I formally entered a new phase of my career: I signed my first book contract. I'll be writing a book about the Curiosity mission through its prime mission, for Springer-Praxis.
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.
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.
