A Mars Reconnaissance Orbiter HiRISE image taken on February 10 shows Curiosity having just made deep, dark tracks across the Dingo Gap dune.
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.

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?

There have been tons and tons of HiRISE images of the Curiosity landing region, and it has taken quite a lot of work for me to find, locate, and catalogue them. This post is a summary of what I've found.
This is Mars is a stunning book that treats the HiRISE camera on Mars Reconnaissance Orbiter as an art photographer, exploring the variety of shapes and patterns created by wind, water, impacts, and gravity on the Martian surface.
Earth's polar vortex has been in the American news all week. But we're not the only planet that has one; basically every world that has an atmosphere has a polar vortex. Here are lots of pretty pictures and animations of polar vortices.
With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa 2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.
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.
The Martian Geologic Time Scale is a lot more complicated than the Moon's.
Yesterday, the much-anticipated comet ISON made its closest pass by Mars. Mars Reconnaissance Orbiter's HiRISE camera is the first to achieve a positive detection of the somewhat-fainter-than-expected comet in its photos.

Space blogger Daniel Fischer provides a preview of the exciting interplanetary observing campaign that has recently begun to study comet C/2012 S1 (ISON) from vantage points across the solar system.
