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.

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.

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

Professor Bell's topic is "Exploring Mars, the Moon, Asteroids, and Comets with Rovers and Landers," and there is no one better to talk about this subject.

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.
Bobak "Mohawk Guy" Ferdowsi of JPL will join First Lady Michelle Obama as a guest at today's State of the Union address.
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.
Curiosity is inching her way through her first use of the drill on a Martian rock. She paused in the proceedings to capture a second Martian "selfie."
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.
I had one of those "A-ha" moments last week where I suddenly realized that I had run afoul of a common problem in science communication: when the words I'm using mean something different to me than they do to almost everyone I'm talking to. The confusing word of the week: "sand."
The Mars I study is really active; the surface constantly changes. We have collected a lot of image data about changing seasonal features near the south pole. There is so much that we can't analyze all of it on our own. We need your help, through a new Zooniverse project named PlanetFour.
