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.
A long-awaited data set is finally public (well, long-awaited by me, at least). The Rosetta team has now published their data from the July 10, 2010 flyby of asteroid (21) Lutetia. This data set is absolutely stunning, and my friends in the amateur image processing community wasted no time in creating art out of it.
Here is a really cool view of Phobos in the foreground with gigantic (but very distant) Jupiter sitting in the background, a fortuitous alignment that the Mars Express High-Resolution Stereo Camera team took advantage of on June 1.
Whenever we explore someplace new -- a new island, a new continent, a new cave, a new world -- there's a necessary activity that explorers must perform before they can sensibly tell the world about their discoveries: name things.
Here are some of the noteworthy items from the morning's session on "Small Bodies: A Traverse from NEOs to TNOs" and the afternoon's session on "Asteroid Geophysics and Processes: Surfaces and Interiors."
Just in time for today's Deep Impact press briefing, which you can watch on NASA TV in a few minutes: I've updated my montage of all the asteroids and comets that have been visited and photographed to include Hartley 2.
I saw these pictures for the first time just 10 minutes before boarding my flight back home, and forced myself to download everything I could find as quickly as possible without pausing to actually look at them.
Rosetta's most important job over the last few months has been to observe how the position of asteroid (21) Lutetia shifts against the background of fixed (fixed, that is, as far as Rosetta can see) stars.
