Last week, planetary astronomers Anne Verbiscer, Michael Skrutskie, and Doug Hamilton published a paper in Nature succinctly titled

Unmannedspaceflight.com member Astro0 was fiddling around with an interesting-looking sequence of Cassini images when he discovered their purpose -- they were gathered in order to see if Cassini could catch aurorae flaring into being near Saturn's north pole. Cassini sure did!

Today's science press release out of the Division of Planetary Sciences meeting concerns changes in lakes near Titan's south pole observed during Cassini's mission. In brief, repeat Cassini RADAR observations of the same spots during different Titan flybys turned up places where there appeared to be dark lakes in earlier images and dry lakes in later images.

The Cassini spacecraft made its 59th flyby of Titan, Saturn's largest moon, on Friday, July 24, and in the last few hours we have received images from the RADAR instrument in SAR (Synthetic Aperture Radar) mode.

Each Titan flyby is not a fork in the road, but rather a Los Angeles style cloverleaf in terms of the dizzying number of possible destinations. So how did our current and future plans for the path of the Cassini spacecraft come to be? That's the question Dave Seal put to me since that's my job -- I am a tour designer.

Saturn is rapidly approaching equinox, where the Sun passes through the ring plane (south-to-north, i.e. the northern vernal equinox), and its ring system (i.e. its great now-gloomy poorly-lit circles of large blocks of water ice) is starting to show some really interesting behavior.

David Seal muses on his time as the mission planner for Cassini, and the history behind its name, and astronomy in Rome.

A very pretty picture of a moon among stars. Happy 2009, everyone!

This time around DPS features three separate oral sessions on Titan, indicating just how much attention that moon is getting from the scientific community right now. From the first session, on Titan's lower atmosphere, I'm just covering the two talks on Titan's lakes.

One of my favorite amateur image magicians, Gordan Ugarkovic continues to play around with the amazing data recently released by the Cassini mission, covering the Iapetus encounter of last September. Here's a lovely mosaic he just put together of the Voyager Mountains.

I thought that today's image release from the Cassini imaging team was exceptionally pretty.

I spent a large portion of the day at the Lunar and Planetary Institute's library and presented my own poster during the poster sessions, so my coverage of Thursday's sessions is limited.

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.

Antares dims and brightens as it passes behind the rings as seen from Cassini in this animation.

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.
