David Seal explains the complications for Cassini coming from Titan's atmosphere and Solar Cycle.

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

Despite still being more than six years and just over 18 Astronomical Units from the Pluto system, the project team for New Horizons is conducting the second and final portion of our Pluto Encounter Preliminary Design Review (EPDR) tomorrow and the next day.

Today, I'm kicking the week off with a look at the unusually intense confluence of far flung planetary exploration that's just around the corner, starting the middle of next year.

It seems like no time since we selected Cassini's extended mission tour of the Saturn system, in early 2007. Now we're flying that tour, which extends Cassini's original four years in Saturn orbit for another 27 months, until September 2010. So now we're looking into the future- far into the future.

Here is every single image of the last two moons discovered prior to the Voyager 2 encounter, Titania and Umbriel.

I got an urge to dive in to the Voyager image archives and see what exactly we have here on Earth to base our understanding of the Uranian moons on.

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.

It's time to check in on what's going on with our trusty robots around the solar system.

Here's what's happening on active planetary missions this week.

I thought it would be fun to start the week by taking stock of what's going on with all the active planetary missions out there.

As New Horizons continues its journey (it's now approaching the orbital distance of Saturn, though it's very far from that planet in space), the mission is taking advantage of the recent experience with the Jupiter flyby to plan out the science operations for the Pluto-Charon encounter.

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.
