Here's a lovely new view of Dione, one of the lovely mid-sized icy moons of Saturn, assembled by Daniel Macháček.
I try to be measured in my praise for spacecraft images. Not every photo can be the greatest space image ever. But this enormous mosaic showing the flattened globe of Saturn floating within the complete disk of its rings must surely be counted among the great images of the Cassini mission.
The Chang'E 2 mission flyby of Toutatis succeeded in acquiring images. Oh my goodness, did they succeed. These, in combination with the incredible radar images still being acquired from Goldstone and innumerable optical observations, make Toutatis one of the best-studied asteroids in the solar system.
A sharp-eyed amateur noticed two images of Titan taken 20 months apart from nearly exactly the same perspective, and they illustrate how the shifting of Saturn's seasons has brought change to Titan's atmosphere.

Back in 1979 the twin Voyager 1 and 2 spacecraft flew by Jupiter. Some of their images were processed into color images and mosaics that have appeared countless times in books, magazines, on TV and on the Internet. Many of these images and mosaics are spectacular but they were processed more than 30 years ago using computers that are extremely primitive by today's standards. It's possible to get better results by processing the original, raw images from the Voyagers using modern computers and software.

I noticed today that I hadn't seen any amateur-processed versions of Voyager's departing shots of Uranus, so I decided to give it a try.
Cassini obtained its first high-resolution images of Methone on May 20, 2012. Methone is one of the smallest regular moons of Saturn, having a diameter of only about 3 kilometers. It was the first moon that Cassini discovered, very early in Cassini's mission at Saturn, in 2004.
I enthused about these Helene images the first time they came down from Cassini, and then forgot about them, and then was thrilled anew a couple of weeks ago when Daniel Macháček posted his version, processed from data published by the Cassini imaging team on April 1.

Cassini flew past both Enceladus and Tethys on April 14. Here's a cool animation of its approach to Enceladus' plumes, and a pretty global picture of Tethys.

Maybe it's my own peculiar variant of pareidolia, but every time I see a new image of Vesta I'm reminded of some different other lumpy body in the solar system. In the image released just now by the Dawn team, taken from 10,500 kilometers away, I'm seeing Hyperion.

I've got some lovely pictures from Saturn to show you! Every three months, the Cassini mission dumps gigabytes worth of precious Saturn data into the Planetary Data System, and the latest gift came on April 1. This particular pile of data, which was taken between April 1 and June 30, 2010, contains a lot of really terrific moon observations.

There is a huge storm that's spreading across so much of Saturn that it's been readily visible even from Earth-based telescopes. Over the past couple of days a couple of new images of Saturn have appeared that show just how enormous the storm is today.

The Mars Express High-Resolution Stereo Camera (HRSC) team has just released several images from the most recent series of Phobos flybys to the Mars Express blog.
