The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.
Scale comparisons of the solar system's major moons

A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.

I'm absolutely floored when I stop to think that our beautiful blue ocean is only one of perhaps a half dozen or more oceans on other worlds in our solar system, and only one of probably millions (or more) oceans on other Earth-like planets in our galaxy. Oceans abound!
Planetary Society Weekly Hangout: Reports from the Lunar and Planetary Science Conference

On Thursday at noon PDT / 1900 UTC I'll report on some of my favorite findings from LPSC, and answer your questions about the latest planetary science.
LPSC 2013: License to Chill (or, the solar system's icy moons)
Posted by Emily Lakdawalla on 2013/03/27 11:52 CDT
Reports from the March 19 session at the Lunar and Planetary Science Conference covering eight icy moons in the outer solar system: Ganymede, Europa, Dione, Rhea, Mimas, Tethys, Enceladus, and Miranda.
Enceladus: A problem of contrast

Time for my quarterly foray into the Cassini archival science data! The very first image I downloaded from the January 1, 2013 data release presented an interesting challenge to my image processing skill. I'll show you the pretty picture of Enceladus and then explain how I processed it.
Happy Cassini PDS Release Day!

It's a quarterly feast day for me: the day that the Cassini mission delivers three months' worth of data to NASA's Planetary Data System. Here's a few images processed from the October 1, 2012 data release.
Pretty pictures from Cassini's recent Dione flyby

Cassini performed its last of three close encounters with Enceladus for 2012 two days ago, and followed the flyby with some spectacular images of Dione.

Cassini flew past both Enceladus and Tethys on April 14. Here's a cool animation of its approach to Enceladus' plumes, and a pretty global picture of Tethys.
Pretty picture: Enceladus, in lovely color

Here's an awesome picture to start off the week. The data came from Cassini's flyby of Enceladus on January 31, 2011; it was part of Cassini's January 2012 data release.�
More radar images of icy moons from Cassini: Iapetus, Enceladus, and Rhea

When I posted about the really cool Cassini SAR images of Enceladus a few weeks ago, I initially wrote that this was the first-ever SAR image of an icy moon other than Titan. Several people (some readers and two members of the Cassini science team!) corrected that statement: Cassini has performed SAR imaging of other icy moons (including Enceladus) before.
First-ever high-resolution Synthetic Aperture Radar image of Enceladus

On the November 6, 2011 flyby of Enceladus -- the third such flyby in just a few weeks -- the Cassini mission elected to take a SAR swath instead of using the optical instruments for once. So here it is: the first-ever SAR swath on Enceladus. In fact, the only other places we've ever done SAR imaging are Earth, the Moon, Venus, Iapetus, and Titan.

Pretty picture: five moons for Cassini

Explaining how to combine the red, green and blue images from a recent Cassini image session containing five of Saturn's moons: Janus, Pandora, Enceladus, Mimas and Rhea.
Lots of great stuff in the latest Cassini data release

I've got some lovely pictures from Saturn to show you! Every three months, the Cassini mission dumps gigabytes worth of precious Saturn data into the Planetary Data System, and the latest gift came on April 1. This particular pile of data, which was taken between April 1 and June 30, 2010, contains a lot of really terrific moon observations.
The curse of living on a geologically active planet

As the disaster of the magnitude 8.9 Sendai quake of Friday, March 11, at 05:46:23 UTC continues to unfold in Japan, I have been unable to tear my attention away.

An amateur named Bernhard Braun ("nirgal" on unmannedspaceflight) has been posting the results from a new piece of software he's developed that generates 3-D models of landscapes from single photos.
Two more awesome pictures from the Enceladus flyby
