Mars Exploration Rovers Update: Opportunity Begins Wrapping Science on Matijevic Hill

A.J.S. Rayl • March 06, 2013

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.

Will comet Siding Spring make a meteor shower on Mars?

Emily Lakdawalla • March 05, 2013

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.

Browse Curiosity's data in the Analyst's notebook

Emily Lakdawalla • March 05, 2013

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.

Curiosity update, sol 193: drilled stuff is in the scoop, ready for analysis

Emily Lakdawalla • February 20, 2013

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.

Field Report From Mars: Sol 3215-3219 - February 6-13, 2013

Larry Crumpler • February 13, 2013

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.

"Sand" means something different to me than it does to you, probably

Emily Lakdawalla • January 24, 2013

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."

Introducing PlanetFour

Ganna (Anya) Portyankina • January 23, 2013

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.
