Professor Bell's topic is "Exploring Mars, the Moon, Asteroids, and Comets with Rovers and Landers," and there is no one better to talk about this subject.
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."
The Curiosity mission held a press briefing this morning for the first time since the American Geophysical Union meeting, and it was jam-packed with science. The biggest piece of news is this: it was worth it, scientifically, to go to Glenelg first, before heading to the mountain.

Watch Planetary Radio LIVE on Saturday!
Saturday's webcast is all about Curiosity on Mars
Watch the live show at 2pm Pacific on Saturday, December 15 to see Bill Nye, Emily Lakdawalla and the leaders of the Mars Science Laboratory rover mission.
Last week the GRAIL mission published their first scientific results, and what they have found will send many geophysicists back to the drawing board to explain how the Moon formed and why it looks the way it does now. To explain how, I'm going to have to back way up, and explain the basic science behind gravity data.
Monday was the big Curiosity day at the fall meeting of the American Geophysical Union. A morning press briefing was followed by an afternoon science session. I traveled to San Francisco briefly just to attend those two events. Here's my notes on the first science reports from the mission.
Water ice at Mercury's poles? That's crazy, right? The MESSENGER team has made a very good case that radar-bright material seen by the Arecibo telescope is, in fact, water ice, covered in most places by a veneer of dark organic material.
Today I stumbled upon the Lunar and Planetary Institute's Lunar Sample Atlas, and was reminded of how much I love petrographic thin sections. They can make unassuming, cruddy looking rocks beautiful.
Planetary Surface Processes provides a rigorous overview of every process that shapes the appearance of planetary surfaces, and I'll be referring to it to help me explain everything from impact cratering to isostasy.
A summary of just one talk from the Division for Planetary Sciences meeting, by Lindy Elkins-Tanton, which provided a neat explanation for how asteroids can be melted and layered on the inside yet have a primitive-looking exterior.
In the first full day of the annual meeting of the Division of Planetary Sciences of the American Astronomical Society, I listened to scientific sessions on icy worlds and on an exoplanet in a four-star system.
A Curiosity press briefing yesterday gave some of the first results from ChemCam and APXS on the rock "Jake Matijevic." It was a little too much petrology for most people; I do my best to explain.

Long-runout landslides (sturzstroms) are found across the Solar System. They have been observed primarily on Earth and Mars, but also on Venus, and Jupiter’s moons Io and Callisto. I have just published a paper about sturzstroms on Iapetus.
I'm hosting this week's Cosmoquest Science Hour, and plan to take viewers on a virtual tour of those mountains on Curiosity's horizon, and show you where Curiosity is likely to go. Join me and Fraser Cain here at 1600 PDT / 2300 UTC Wednesday.
Some notes from this morning's Curiosity press briefing: the rover will be driving to "Glenelg" to investigate the "high thermal inertia unit." I explain what that means, with psychedelic Odyssey THEMIS images of the landing site.
