My notes on a two-part presentation by collaborators Jim Richardson and David Minton about the sizes of things in the Kuiper belt, a story they told by looking at Saturn's moons. How does that work? What connects Saturn's moons to the Kuiper belt is craters.

Today was (is) the last day of the Division of Planetary Sciences / European Planetary Science Congress meeting in Nantes, France.

It's already the last day of the DPS/EPSC meeting in Nantes, France, and I've fallen seriously behind on writing up my notes. I thought I'd get some less pleasant notes out of the way before I returned to science.

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

During the afternoon poster session at the Division of Planetary Sciences / European Planetary Science Congress meeting, I had a long talk with Ludmila Zasova (IKI) about Russia's Venera-D mission to Venus.

It's been a very full day at the DPS-EPSC 2011 joint meeting. My day was less full than it might have been, because I overslept and missed most of the morning's session. I really needed the rest though so I think it was probably for the best!

I arrived in Nantes just in time to see two major figures in the Planetary Society win big awards.

Today they turned on the scientific fire hose at the Division of Planetary Sciences / European Planetary Science Congress meeting happening here in Nantes, France. My brain already feels full and I still have four more days!

Jeff Moore's presentation was cool because of the discussion it stimulated. He considered what exogenic processes might be operating on Pluto's surface. What's an exogenic process? It's something that modifies the shape of the surface from the outside, and doesn't require the body to be geologically active inside.

The second day of the New Horizons Workshop on Icy Surface Processes was about geology and geophysics. This long post just covers the first talk of that day.

Today and tomorrow I'm attending the New Horizons Workshop on Icy Surface Processes. The first day was all about the composition of the surface and atmosphere of Pluto, Charon, Triton, and other distant places.

In this, my second blog on Origins 2011 in Montpellier, France, a conference dedicated to the interdisciplinary research on the origins of life, I aim to provide my impression of the second half of the conference.

The program and abstracts for the next big space meeting have now been posted, and there's a lot of great stuff to look forward to.

The Origins 2011 conference, which took place last week in Montpellier, France, was dedicated to the origins of life and its occurrence in the universe. At this meeting, scientists from very different disciplines came together to share their ideas.

About a week ago, I attended the meeting of an organization I am excited about: the Alliance for Earth Observation. The conference was remarkable.

Some recent high-resolution images from the Lunar Reconnaissance Orbiter Camera (LROC) have revealed large blocks on the lunar surface that show evidence of layers. The layered blocks were seen near the crater Aristarchus, which is a bright crater in the northeast quadrant of the nearside Moon.

Saturn's moon Hyperion has a bizarre sponge-like appearance that is in dramatic contrast to other heavily cratered bodies in the solar system.

Here are Ted Stryk's notes from the sessions he attended in the afternoon of Thursday, March 10, at the 42nd Lunar and Planetary Science Conference.

I'd been despairing of finding a good source for a writeup of the presentations in the Hayabusa session at last week's Lunar and Planetary Science Conference, but am happy to report that I've finally found an excellent one.
