There was a press release from the Cassini mission today about a pile of papers (14 of them!) being published in the journal Icarus about Saturn's icy moons. I haven't had time to read more than the overview article yet, but I wanted to come up with a graphic for an overview of Saturn's moons, and I couldn't resist delving into the massive database of Cassini images to produce something new

One of the major results from the Cassini mission last year was the production of a mosaic of images from its RADAR instrument covering Titan's north pole. Titan's north pole has lakes upon lakes, some big, some small, but everywhere you look, there they are.

Lakes have been spotted near the south pole of Titan before, in this image by the ISS team, which was considered compelling but not conclusive at the time.

This afternoon Alan Stern posted to unmannedspaceflight.com that New Horizons has successfully completed the trajectory correction maneuver that lines the spacecraft up for its July 14, 2015 encounter with Pluto.

There's been quite a lot of Mars on this page for the last week; it's time to remind ourselves that there are other places besides Mars in the solar system.

The other day I posted a global view of Titan featuring new territory near the north pole. Now the imaging team has released a much higher resolution version of this view.

Here we bring you fifteen different Cassini views of the same world, a cratered ball of ice called Tethys.

Cassini has just begun its 44th orbit of Saturn (called Rev 43), and is starting it off with lots of views of famously two-faced Iapetus.

This image is beautiful for many reasons. It was captured by the MVIC imaging spectrometer, part of the Ralph instrument, on New Horizons, as it left the Jupiter system on March 2, 2007.

I received this report on the Tuesday afternoon special session on volcanism and tectonism on Saturn's satellites from Anne Verbiscer, an astronomer from the University of Virginia who I first met at the Division of Planetary Sciences meeting in 2005.

The Tvashtar eruption continues to amaze. All this time between Galileo and New Horizons, Io's volcanoes have probably continually produced spectacular eruptions like these.
