Cassini sends us this rather awesome image of Prometheus tugging at the thin F-ring. Far weaker than magenetism, images of gravity at work are rare and, I think, profound.

Rosetta, the ESA mission to orbit and place a lander upon a comet, is approaching its secondary target, the asteroid Steins.

Opportunity has succeeded in leaving Victoria Crater, and seems to still be going quite strong, save a few issues with her shoulder.

Finally, you may recall my fascination with (and unhappy ignorance of) orbital mechanics. The latest journal from Dawn Project System Engineer Marc Rayman serves up an entertaining and straightforward introduction to rocket science, so go read it right now.
