The Saturn system is always in motion, always changing. Saturn itself is a gas giant, with swirling storms, and like the other gas giants it has a host of moons flying around, perturbing each other's motions. And then there's the rings.

Every time I think Cassini has captured the coolest image of Enceladus ever, it does better.

Cassini flew within 436 kilometers of Enceladus' surface today. Although it's Cassini's 11th targeted flyby of Enceladus, these close buzzes are never routine.

Every time Cassini gets reasonably close to one of the moons of Saturn, whether the close approach is a targeted one or just an opportunistic encounter, its planners usually take advantage of the proximity to take a bunch of photos.

A good start to my day today: The New York Times' Lens Blog featured the "Martian Moment in Time" photo that Opportunity took last week in a really nice writeup. I'm so grateful, and still a little surprised, that the folks on the Mars Exploration Rover mission took this idea and ran with it!

Wow, this is a cool paper. Here's the gist: the Cassini RADAR team has spotted some river channels on Titan that shine so brightly in radar images, there must be something special going on to explain that brightness.
A lot of readers have expressed interest in the origin of Saturn's north polar hexagon. The hexagon is a long-lived pattern in the clouds surrounding Saturn's north pole, which has been observed since the Voyagers passed by in 1980 and 1981.

Here's a new lovely color composition of Titan and Dione captured by Cassini. This one was taken on April 20, 2010; a set of 15 raw images taken of the two moons just showed up on the Cassini raw images website.

The Cassini Saturn orbiter just completed its second very close flyby of Saturn's mid-sized iceball moon Dione, and the images from that encounter have been streaming onto the Cassini raw images website this morning.
