The Mysterious Moving Rocks of Mars
How did the boulders in the picture above end up in clumps and arcs instead of randomly distributed across the surface? That’s the focus of the paper “Possible Mechanism of Boulder Clustering on Mars” by Travis Orloff, Mikhail Kreslavsky, and Eric Asphaug that is currently In Press in the journal Icarus.

Where does Earth get its heat?
The other day I got a message asking about where the earth gets its heat. It brings up a number of misconceptions that I thought would be worth spending a post discussing, so here goes: Many people assume the earth to be millions if not billions of years old. Lava is molten, but the earth being only 8,000 miles in diameter has no internal heat source. It is almost like …

Using a very strong light to study rock number four
To jump on the bandwagon, here is my research, described using only the 1000 most common English words. It would have been nice if “Mars” and “Laser” and “Robot” were available:

The two-faced crust of Mars
I am always a sucker for research that uses very simple observations to come to profound conclusions, and that is definitely the case with “The dual nature of the martian crust: Young lavas and old clastic materials” by Josh Bandfield, Chris Edwards, David Montgomery, and Brittany Brand.

AGU 2012: Days 1 and 2 Highlights
Greetings! It’s been a busy first two days of AGU, and it’s impossible to convey it all, but here are a few highlights: Monday morning was my poster presentation, so that prevented me from seeing very many talks. I did stop by the Mars talks long enough to hear ChemCam team member Darby Dyar give a talk summarizing the many challenges involved in getting quantitative numbers out of LIBS data, …

AGU 2012
Greetings from San Francisco! I have to say, flying here from Flagstaff is a lot nicer than flying from Ithaca. And the scenery from the first leg of the trip is hard to beat: The view out my hotel room window here in San Francisco is somewhat less scenic. It overlooks the loading dock of a Bloomingdale’s. BUT I’m not here for scenery. I’m here for the AGU “fall” meeting, …

Thanksgiving With the Kranzes
I post this pretty much every year, but it’s too good not to share. If you’re feeling ambitious, Gizmodo also has some… “interesting” ways to cook a turkey from NASA engineers. I personally like the sounding rocket method.

MSL Instrument Papers Available!
Just in time for the thanksgiving holiday, Space Science Reviews has released its special issue containing all the instrument papers for MSL, along with papers describing the mission’s overall goals, the landing site selection process, and the studies of the atmosphere that helped NASA stick the landing. So this year while you wait for the turkey to cook, take a look at some of these papers and learn about the awesome laboratory that is exploring Mars and give thanks that we live at a time when such things are possible. I’m sure your family won’t mind once you tell them what interesting stuff you’re reading… 🙂
