As Cassini celebrates 10 years at Saturn, we're beginning to see its long-term observations of Saturnian moons bear fruit. A surprising new result: While Prometheus exerts control over the F ring and Atlas, Pandora -- long thought to be a shepherd of the F ring -- does not.

The last couple of weeks have seen Curiosity return to the business of making steady headway toward Murray Buttes and, beyond them, Mount Sharp. Eight of the last 14 sols have seen drives ranging in length from 30 to 104 meters, racking up a total of more than half a kilometer. They are now occasionally working a shortened planning timeline that allows them to squeeze more drive sols into Curiosity's schedule.

A few people think that when it comes to the Moon, because we’ve “been there, and done that,” there is nothing new left to discover. But that viewpoint could not be farther from the truth!

Today I received an email notification of new public releases of some image data sets. I always love seeing new public space image data, but this notification was bittersweet: it included the first public release of the very last image data returned to Earth by Deep Impact, of a distant comet ISON.

Mars Express and Mars Reconnaissance Orbiter are keeping their eyes in the sky on Curiosity. There's a nice newly public color image of all of Gale Crater from HiRISE, and two new HiRISE images within the Curiosity landing site.

Have you ever wished you could enjoy the astronauts' view of Earth from the Space Station? Now, you can. Just go to the live feed from the High Definition Earth Viewing (HDEV) experiment, crank it up to its highest resolution, let it take over your monitor, and watch Earth spin by.

Curiosity took a new self-portrait on sol 613. This post contains a tip for would-be Curiosity image processors on how to make their Curiosity mosaics better: removing the smearing effect of bright objects in MAHLI photos.

The Cassini mission has already returned an array of images of other solar system members from Saturn orbit: Earth (and the Moon), Venus, Mars, and Jupiter. It’s time to add another world to that list!

LADEE ended its mission as planned with a crash into the lunar surface on April 17. Just days prior, it turned its star tracker camera toward the lunar horizon and captured a striking series of images of the lunar sunrise and zodiacal light.
