Two new blogs to follow: 3D planets and image treasures
Two great new planetary science-themed blogs have just started up, and rather than repost everything they've posted so far (which is what I've really wanted to do), I'll just give a summary and point you over there to read. Having done that, though, I'm sure I still won't be able to keep myself from reposting a bunch of their stuff. They just have too many pretty pictures to share.
The first one is Dr. Schenk's 3D House of Satellites. Paul Schenk is a researcher at Houston's Lunar and Planetary Institute whose specialty (well, one of his specialties) is figuring out the topography of outer solar system moons. He derives 3D information both from stereogrammetry (looking at two pictures of the same spot from different angles, the way humans see in 3D) and from photoclinometry (analyzing the lengths of shadows to determine heights of shadow-casting points). Here's a striking view from his recent entry on Enceladus:
