A close look at two international planetary science poster presentations from the 2013 AGU Fall Meeting featuring sediment experiments to better understand Martian geomorphology and Juno's plans for exploring Jupiter's ring system.
In a Martian first, the Curiosity science team has measured the age of a Martian rock, in two totally different ways. They presented the result at the 2013 meeting of the American Geophysical Union.
I'm returning to the deep dive into the literature that began with articles about lunar basins and then explored the geologic time scales of Earth, Moon, and Mars. Now it's time to catch up to the last decade of Mars research and learn what "phyllosian", "theiikian", and "siderikian" eras are.
Although winter took hold at Endeavour Crater in November, Opportunity pressed on, climbing up Murray Ridge and driving into a clay mineral hunting ground as the Mars Exploration Rovers mission cruised another month closer to celebrating its 10th Earth year of surface operations with myriad events throughout January 2014.
In 1971 I was being trained to work with the airbrush by the map artists at the U.S. Geological Survey's Branch of Astrogeologic Studies in Flagstaff. However, the project I ended up spending about a quarter of a man-year on was a hand-painted map globe of Mars.
An electrical problem frustrated progress on the Curiosity mission this week, but the problem is now understood and the rover back to work.
On sol 3485 Opportunity pulled up next to a large outcrop here on the rim of Endeavour crater. The outcrop appears to be impact breccias like those we saw a few sols ago lower down on the ridge. But the texture of the rocks is somewhat different.

The Jet Propulsion Laboratory announced today that the geologists on both Mars rover teams -- Opportunity and Curiosity -- have named landmarks at their field sites after the late Bruce Murray.

Having racked up several kilometers in the drive to Mount Sharp, Curiosity paused for a second science stop at an outcrop called "Cooperstown." While there, the rover performed a software upgrade and then lost a few days to a software anomaly. The rover has now resumed normal science operations.
Cosmos with Cosmos Episode 5: Blues for a Red Planet
Where Mars stubbornly refuses to be what we desire
Episode 5 focuses on Mars, the planet that has stubbornly refused to conform to the wishes of humanity for hundreds of years, from Lowell to Sagan. Grab your cosmo and join our discussion of 'Blues for a Red Planet.'
As fall began to give way to winter at Endeavour Crater, Opportunity cruised deeper into her campsite on the western side of Solander Point in October, heading for a site that may contain clay minerals and the rover's next big discovery, and the Mars Exploration Rovers mission trekked another month closer to its 10th anniversary in January 2014.
On sol 3451 Opportunity began its climb of Solander Point. This is the highest “mountain” that Opportunity has tried to climb yet.
The Martian Geologic Time Scale is a lot more complicated than the Moon's.
After a brief science stop at Darwin (formerly known as Waypoint 1), Curiosity has driven hundreds of meters toward Mount Sharp. Autumn has come to Curiosity's southern hemisphere location, bringing lower temperatures. That means more power is required to heat rover actuators, leaving less power for science along the drive.
What did I learn about Curiosity at last week's Division for Planetary Sciences meeting? There were a few talks, most of which concerned soil and atmsospheric chemistry. I can summarize their conclusions with one sentence: More data is needed.
