Planetary Society Advent Calendar for December 20: 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.
Cassini VIMS sees the long-awaited glint off a Titan lake
The Cassini mission announced today the first observation of a specular reflection off of a lake on Titan. A specular reflection is a mirror-like flash, and you only get one when you have a mirror-like surface -- very, very smooth.
Planetary Society Advent Calendar for December 16: Mimas
Mimas is the anti-Enceladus.
Planetary Society Advent Calendar for December 12: Saturn
Cassini's amazing cameras have set a new standard for the quality, sharpness, resolution, beautiful color, and all-around spectacularness of images returned from the outer solar system.
Awesome Mars Express view of Phobos and Deimos together
My inbox was exploding this morning with messages about a tremendously cool animation released this morning by ESA's Mars Express team. It shows Phobos crossing Deimos, in what's known as a
Planetary Society Advent Calendar for December 9: Atlas
Here's another weird-looking one, though it's less weird from this particular, polar point of view than it is when viewed from the side.
Planetary Society Advent Calendar for December 5: Epimetheus
Epimetheus is one of the many small moons of Saturn that are referred to by the Cassini mission team as
Planetary Society Advent Calendar for December 1: Dione
I've always loved advent calendars and the way they both managed and heightened my anticipation of the gift-opening frenzy of Christmas morning.
Saturn's aurora, even better than before
The Cassini imaging team have posted their own processed and captioned version of the Saturn's aurora movie that I posted a preview of about six weeks ago, and it was worth the wait.
Two more awesome pictures from the Enceladus flyby
I'm getting to be a broken record here, but I can't stop looking at these photos from the Enceladus flyby.
Prepare for your jaw to hit the floor when you see these pictures of Enceladus
Wow, just wow. I didn't know what to expect from the second flyby of Saturn's geyser moon Enceladus in November, which happened yesterday.
Another great Enceladus shot
Here's a 4-frame mosaic of Enceladus images -- just another everyday spectacularly alien landscape.
Opportunity's poking at Marquette Island; Cassini's catching dancing moons
Since tomorrow's class is going to be on playing with raw images from the rovers and Cassini, I've been playing with recent raw images from the rovers and Cassini! I just thought I'd share a couple of the fun items I've been working with.
Four moons and a ring
Thanks to Mike Malaska for the tip on this one. The image is part of an animation that ends with Rhea transiting Saturn.

Another marvelous image from Cassini's Nov 2 Enceladus flyby
This image goodie was produced from the raw images from Cassini's close encounter with Saturn's geyser moon Enceladus yesterday by Gordan Ugarkovic.
Cassini's Enceladus encounter, with bonus Tethys
Raw images from Cassini's close pass by Enceladus today started appearing on the JPL raw images website, and some less-compressed versions of a few of them showed up on the CICLOPS website.
Fun Friday photo: Titan and Rhea
Cassini recently captured a series of images documenting Rhea passing behind Titan.
What "phase angle" means
As is probably obvious by now, I love playing with spacecraft image data. I am always looking for excuses to dive into space image archives to unearth images of stuff in space that haven't really been seen by very many people before.
