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.

Nearly four decades before Curiosity, we dug into Mars for the first time. The pictures are still amazing.

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.

Last week the Curiosity mission made its first data delivery to the Planetary Data System. The bad news: none of the science camera image data is there yet. The good news: there are lots and lots of other goodies to explore.

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.

Opportunity completed the observations of the outcrop noted in the previous report and has now moved back down slope.

There was a press briefing today to announce that Curiosity has completed her last major first-time activity: powder drilled from inside a rock at John Klein successfully made its way into the CHIMRA sample handling mechanism in the turret. Sol 193, then, marks the day that Curiosity is finally ready to start the science mission.

Damien Bouic received some well-deserved recognition from the Chemcam team for his great Curiosity image processing work.

We have been seeing lots of small light-colored veins crossing through the outcrops here on Matijevic Hill, and we have tried to get a handle on the composition of these veins by doing multiple offsets with the APXS. It appears that the small veins are calcium sulfate, as best we can determine.

With its robot nose to the Martian grindstone, Opportunity completed its ninth year of working on Mars in January, making another significant science discovery in tiny white veins on Matijevic Hill as the Mars Exploration Rover (MER) mission rolled on into Year 10.

A conversation on Twitter today reminded me of this photo, which is one of my all-time favorite space images: the view from Rosetta during its Mars flyby.

They're getting closer and closer to drilling. Curiosity now seems to be positioned in the spot where they plan to be when they execute that long-awaited first drill.

Just like on Earth, clouds and storms often ripple through the Martian atmosphere. You can even check the daily weather report.
