A conversation on Twitter today reminded me of this photo, which is one of my all-time favorite space images: the view from Rosetta during its Mars flyby.

Time for my quarterly foray into the Cassini archival science data! The very first image I downloaded from the January 1, 2013 data release presented an interesting challenge to my image processing skill. I'll show you the pretty picture of Enceladus and then explain how I processed it.

The Planetary Society remains committed to a balanced program of solar system exploration, with Mars, outer planets, and small missions all playing an important part.

They're getting closer and closer to drilling. Curiosity now seems to be positioned in the spot where they plan to be when they execute that long-awaited first drill.

Just like on Earth, clouds and storms often ripple through the Martian atmosphere. You can even check the daily weather report.

Recently, several of the Kuiper Belt Objects our team has discovered while searching for New Horizons post-Pluto flyby candidates have been submitted to the Minor Planet Center and their orbital information is now in the public domain.

The Mars I study is really active; the surface constantly changes. We have collected a lot of image data about changing seasonal features near the south pole. There is so much that we can't analyze all of it on our own. We need your help, through a new Zooniverse project named PlanetFour.

What is the highest resolution global Jupiter mosaic that includes a satellite transit that can be assembled from Voyager images? Satellite transits are especially beautiful when the resolution is high enough for some details to be visible on the satellites so I decided to check this. And I was remarkably lucky.

My solar system chauvinism is well-established, but I am as much a sucker for beautiful astrophotos as the rest of you. Once in a while I get a media advisory from the European Southern Observatory about a new pretty picture posted on their website, and then I inevitably lose an hour following links to one stunner after another.

Last week at a meeting of NASA's Small Bodies Assessment Group (SBAG), Han Li of the Chinese Academy of Sciences gave a lengthy presentation on Chang'E 2. Her presentation included a new sequence of photos from the December 13 Toutatis flyby.

Mars Reconnaissance Orbiter captured a new view of Curiosity on Mars on January 2 (sol 145). Curiosity was in the same location as the one from which it shot the sol 137 panorama I posted earlier. You can see the rover's tracks leading all the way back to the landing site!

The Curiosity mission held a press briefing this morning for the first time since the American Geophysical Union meeting, and it was jam-packed with science. The biggest piece of news is this: it was worth it, scientifically, to go to Glenelg first, before heading to the mountain.

The 2020 Rover will achieve its cost-savings by using $200 million of existing hardware left over from the Curiosity mission, said the Director of the Planetary Science division within NASA.
