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.

An attempt to bump left and get a small bright vein into the instrument deployment device (IDD) work volume failed to get the target in the work plane.
Near-Earth asteroid 4179 Toutatis will be passing within 7 million kilometers of Earth on December 12. Both radio telescopes and the Chang'E 2 spacecraft will be acquiring images.
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.
The Planetary Society has a new weekly Google+ Hangout time slot, Thursdays at noon PT / 1800 UT. This week, Casey Dreier and I talked about the Curiosity kerfuffle and NASA's future rover plans. Here's the archived recording.
Now that Casey has explained the budget implications of yesterday's 2020 rover announcement, and The Planetary Society has issued a formal statement, I thought it was time for me to talk briefly about science.
I'm in San Francisco, reporting from the American Geophysical Union meeting. This morning, there was a much-anticipated press briefing featuring the latest results from Curiosity.

Here at station 14 we have decided to do a detailed investigation of an outcrop that is well exposed and lies within an area where there is orbital remote-sensing evidence for clay minerals. These particular rocks are interesting in that they contain a lot of thin veins and alteration zones along joints (cracks) in the outcrops.
