Vignettes from dozens of LPSC talks: GRAIL and LADEE at the Moon; ice and craters and conglomerates and organics and gullies on Mars; polar deposits and volatile elements on Mercury; tectonics on Enceladus; and more, until my brain was so full I could barely speak.

With a series of drives over the last week, Curiosity is now approaching her next science stop at Kimberley. The distinctive knobs of the Kimberley outcrop are visible in photos taken on sol 569.

Europa may get a mission...eventually. We give our first take on the 2015 NASA Budget request. How does Planetary Exploration fare? Which projects were cancelled? Will NASA capture an asteroid? And most importantly, what can you do about it?

The United States Geological Survey recently issued an improved version of the Viking color map of Mars. This 40-year-old data set still provides the prettiest global-scale map of the planet.

Check out this unusual crater on Mars. It's not a very big one, less than 500 meters in diameter, and yet it has two rings. Most craters on Mars this size are simple bowl shapes. What's going on here?

On Sunday, 19 October 2014, at around 18:30 UTC, comet C/2013 A1 – known widely as 'Siding Spring' after the Australian observatory where it was discovered in January 2013 – will make a close fly-by of Mars.

Today is the tenth anniversary of Opportunity's landing on Mars. Here at the New Mexico Museum of Natural History and Science, we just opened a tenth anniversary exhibit.

Opportunity arrived at the location that has been the target of all this climbing since late last (Earth) summer. We will settle in for some detailed work on the outcrop here since this appears to be something different from the impact breccias that we have been seeing along the ridge crest.

Opportunity is still exploring an outcrop high up on Murray Ridge as the winter solstice on Mars approaches. At this location the tilts are good, so Opportunity is getting excellent solar input on its solar panels.

I have a pet peeve: the words dune and ripple are often used interchangeably, although they are quite distinct from one another. So what’s the difference between aeolian dunes and ripples? And why should anybody care?

In the storied history of the Mars Exploration Rovers (MER) mission, January 2014 will likely be remembered as one of the most memorable months of all.
