Stunningly beautiful photo of Dione and Saturn with rings. Such a sensation of depth and grandeur. Thanks, Cassini/JPL/NASA. [animation] [planetary photojournal entry] [B/W mirror from kokogiak] [now you play fun Flash spaceship game].

Cassini Flies by Tethys and Hyperion, and the photos so far have been awesome and weird. I especially want to point out this fascinating view, which, if you look at it closely, reveals what appears to be a string of small impact craters, in a straight line over older terrain. What kind of meteor impact could have produced such an excellent formation of craters? Hyperion photos are coming. (Kokogiak's got backup in case the JRUNS strike.)

Two Moons Passing in the Night. Mars rover Spirit took these sequential photos of Martian moons Phobos and Deimos passing overhead in the night sky. Those rovers are still going strong!

Rocks Among the Rings. The Planetary Society's Emily Lakdawalla has compiled some of the loveliest imagery of Saturn's ring-and-moon system from Cassini. More on Saturn from the Planetary Society here. Also see the Cassini at Saturn photoset, from our very own kokogiak, and watch for updates on the latest Enceladus flyby.

"Standard orbit, aye, sir." Following a nail-biting ring-plane crossing and 96-minute engine burn, Cassini has arrived, and is now in orbit around Saturn, 84 light-minutes away, sending in the first closeup pictures of the planet's rings. Also see the Planetary Society's details on the Orbit Insertion, Spaceflight Now's mission updates in weblog-like format, and raw images from the spacecraft as they come. Kudos, JPL! (Aside: the press has yet to tire of Lord of the Rings references.)

NASA and the Mars Bunny. I first heard about it from our own kokogiak. Then the conspiracy theorists: "They're destroying the evidence!" But now NASA has come out to tell us, "It's probably just airbag material."

Far, far away. Today, Voyager 1 will reach 90 AU from the sun, around which distance it is expected to cross the "termination shock," finally crossing into the fuzzy boundary between the heliosphere and true interstellar space. (Yes, it's taken that long to get there.) Some even think that the termination shock has already been reached, but then re-expanded past the spacecraft. Tears need not be shed yet for these distant explorers: both Voyagers have juice till about 2020, and the mission remains very much alive. (No word, however, on a possible return to the Creator.)
