Stories, updates, insights, and original analysis from The Planetary Society.
Google Maps released several new map products that allow you to see the locations of named features on many solar system planets and non-planets, spinning them around in space with your mouse.
The Division of Planetary Science (DPS) Meeting saw many exciting scientific discussions spanning the range of processes on different planetary bodies, as well as their replication in the laboratory and in models.
Now that Cassini has returned to Saturn's equatorial plane, it has lots of opportunities to observe Saturn's moons. For about a week, Cassini has been taking regular sets of images of Iapetus, which I've assembled into an animation.
In pictures of the planets, the stars aren't usually visible. But when they do appear, they're spectacular.
A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.
Long-runout landslides (sturzstroms) are found across the Solar System. They have been observed primarily on Earth and Mars, but also on Venus, and Jupiter’s moons Io and Callisto. I have just published a paper about sturzstroms on Iapetus.
A new paper in the Journal of Geophysical Research - Planets by Dombard, Cheng, McKinnon, and KayI claims to explain how Iapetus' equatorial ridge formed. Cool!
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.
I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.
Today and tomorrow I'm attending the New Horizons Workshop on Icy Surface Processes. The first day was all about the composition of the surface and atmosphere of Pluto, Charon, Triton, and other distant places.
Here are Ted Stryk's notes from the sessions he attended in the afternoon of Thursday, March 10, at the 42nd Lunar and Planetary Science Conference.
Time to open the sixth door in the advent calendar. Where in the solar system are these snowy slopes?
A couple of weeks ago Paul Schenk posted a few really cool videos to his personal blog. Paul's subspecialty is the topography of icy moons, and he's been doing a lot of work on the moons of Saturn lately.
I've spent a pleasurable hour or so browsing over the latest release of images from Cassini to the Planetary Data System.
I visited the Cassini raw images site today and was pleased to see another couple of sets of images have been captured on Iapetus.
Iapetus! I'm always interested in Cassini images, but five years ago this month I was refreshing the Cassini raw images website several times a day, eagerly anticipating the mission's first good encounter with Iapetus.
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.
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
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.
Iapetus is one of the many fascinating bodies in the Saturn system.
