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.

Today I largely spent in the MESSENGER sessions. They have a lot of data to talk about.
