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.

Regular readers of this blog will find the content of today's 365 Days of Astronomy Podcast familiar, because it's an update on what the solar system exploration spacecraft are up to, based on my monthly "what's up" updates.

This is both a Lunar and Planetary Science Conference (LPSC) update and a public service announcement. Ted Stryk has been working for years to locate the original Pioneer 10 and 11 image data from the Jupiter and Saturn encounters.

This week is the end for Kodachrome film. It's a casualty of the digital revolution.

Time to open the twentieth door in the advent calendar. Where in the solar system is this diffuse blob and stripy sea?

Today the 365 Days of Astronomy podcast aired my contribution, What's in a Science Meeting?, about what scientists do at big meetings like the Division of Planetary Sciences.

The Cassini Raw Images Website always offers rewards to the browser. This evening I found the raw images necessary to create this color composite, showing the hazy orange moon Titan, the mid-sized icy moon Dione, and the tiny rock Prometheus all at the same time.

Last week I posted a stack of Voyager Mission Status Bulletins, which were once the main resource for space enthusiasts to follow the dramatic events and photos of an in-flight space mission.

In response to Emily's entry about finally getting her hands on a subscription to the planetary science journal Icarus, I thought I would report on an article from the most recent issue: Geology of the Selk crater region on Titan from Cassini VIMS observations, by Jason Soderblom and 11 other scientists.

There's a new "planetary gromorphology image of the month" posted at the International Association of Geomorphologists' Planetary Geomorphology Working Group page, and it's a cool post about the shapes of the river networks on Titan.

Every time I think Cassini has captured the coolest image of Enceladus ever, it does better.

Wow, this is a cool paper. Here's the gist: the Cassini RADAR team has spotted some river channels on Titan that shine so brightly in radar images, there must be something special going on to explain that brightness.

Here's a new lovely color composition of Titan and Dione captured by Cassini. This one was taken on April 20, 2010; a set of 15 raw images taken of the two moons just showed up on the Cassini raw images website.
