We have new pictures from planet one.

Just four months ago I posted about a paper recently published by Leslie Young and coauthors that described three possible scenarios for Pluto's atmosphere. Yesterday, Cathy Olkin, Leslie Young, and coauthors posted a preprint on arXiv that says that only one of those scenarios can be true. And it's a surprising one. The title of their paper says it all:

Starting at 7:30pm PDT/10:30pm EDT, we will webcast a special event around the launch of NASA's next lunar spacecraft. Watch our special coverage with lunar scientists and live video from the launch site, as well as NASA TV footage of the launch itself.

The Advanced Stirling Radioisotope Generator (ASRG) is no longer an option for powering a potential Europa mission. The ASRG uses Plutonium-238 to generate electricity, but is far more efficient than past RTGs.

From sols 373 to 383 (August 23 to September 3, 2013), Curiosity traveled about 250 meters toward Mount Sharp over five drives, trying out her new AutoNav capability.

What have the recent discoveries of thousands of exoplanets told us about how we got here, and whether we are alone? In Destiny or Chance Revisited, Stuart Ross Taylor attempts to answer those two questions.

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.

Bruce Murray was an early advocate for the inclusion of cameras on planetary spacecraft. As a tribute to him, I thought I'd take a look at a few of the images from the early Mariner missions to Mars.

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!

Beautiful maps of a mysterious place.
