There wasn't a dull moment for the Mars Exploration Rover mission in August as Opportunity drove up to the base of the Solander Point section Endeavour Crater's eroded rim, crossed over a geological boundary between ancient eras, maneuvered through a boulder field, scooting unscathed from a near-miss with a rock that could have ended it all, and at month's end delivered her team to what looks to be another scientific gemstone on the Red Planet.

Traveling confidently and alone, Dawn continues to make its way through the silent depths of the main asteroid belt. The interplanetary adventurer is on its long journey to the uncharted dwarf planet Ceres, by far the largest of all asteroids.

By now I hope that everyone has seen some of the spectacular images of the Saturn system (and especially Titan!) from the Cassini-Huygens mission. However, the measurements that often make my heart race are taken by instruments that reveal Titan in ways that our eyes cannot see.

New Horizons has just completed a summer of intensive activities and entered hibernation on Aug. 20. The routine parts of the activities included thorough checkouts of all our backup systems (result: they work fine!) and of all our scientific instruments (they work fine too!).

Those sneaky scientists on Curiosity managed to catch a Phobos transit of the Sun with one set of cameras, and to watch its shadow darkening the surface with another. COOL!

The world's great telescopes capture stunning photographs of stars, nebulae, and other sky phenomena. In Europe to the Stars, authors Govert Schilling and Lars Lindberg Christensen share many such photos. But the real stars of this book are the great telescopes of the European Southern Observatory.

Yesterday, the Curiosity mission released the video whose potential I got so excited about a couple of weeks ago: the view, from Curiosity, of Phobos transiting Deimos in the Martian sky. In this post, Mark Lemmon answers a bunch of my questions about why they photograph Phobos and Deimos from rovers.
