Alien Seas is ostensibly a book about "oceans in space," but it delivers so much more. The slender volume contains essays by many active planetary scientists who also happen to be excellent writers, each one of them playing a different riff on the idea of oceans in different environments in the solar system.

Curiosity activities over sols 465 to 487 included monitoring the condition of the wheels; a flight software upgrade; and dumping the Cumberland drill sample. Curiosity put approximately 200 meters on the odometer during this period.

Major revelations about our solar system at last week's AGU conference came from near and far. Emily Lakdawalla and Casey Dreier share a few, while Bill Nye salutes China's Chang'e 3 lunar lander and rover.
Today there was a lengthy press briefing by several members of the Chang'e 3 science team. A complete transcript was posted in Chinese. I have run it through two machine translators and found it to be quite informative, not just about the mission but also about attitudes about Chinese space exploration and foreign cooperation. I also have a cool fan-produced video to share.
Cosmos with Cosmos Episode 8: Journeys Through Space and Time
Are we imprisoned in both?
Sagan makes us confront the limitations of our mortality given the immensities of space and time presented to us by the cosmos.
Juno's Earth flyby represented the first opportunity for many of the science instruments to be used on a planetary target. There were terrific photos of Earth and the Moon, plus a cool project to see if Juno could detect intelligent life on Earth.
It's time to reassess Europa exploration, past, present and future. The Destination Europa! session at AGU, inspired by the eponymous website and movement, didn't take exactly that message as its theme, but it's what I got from the presentations. What an ELECTRIFYING meeting this has been for Europa exploration!
Fresh off of Chinese state television are lovely pictures taken by Chang'e 3 lander and rover of each other!
Here it is! Animated gifs, composed of screen grabs from Chinese state television, of the Yutu rover rolling on to the lunar surface. This was a replay, but it was no less thrilling for that; the actual rollout happened at 20:40 UT (12:40 PT). Six wheels on soil! Woohoo!
Transmitting images all the way down, China's Chang'e 3 lander successfully arrived on the lunar surface at 13:11:18 -- half an hour before the scheduled landing time. Rover deploy is set for a few hours later.
Op-Ed: The new space race: It's not just the U.S. and Russia anymore
There are now many space programs, both national and private. And that's good for science.
I once argued that the concept of a space race represented old thinking. The modern way forward in space would be through international cooperation and coordination. Today, I think my insistence that the space race was over was naive. There are now many space races.
According to numerous Chinese news reports, Chang'e 3's landing on the Moon is now scheduled to begin at 21:40 Beijing time on December 14, which is 13:40 UT or 05:40 PT. That's about two hours earlier than previously stated.

A close look at two international planetary science poster presentations from the 2013 AGU Fall Meeting featuring sediment experiments to better understand Martian geomorphology and Juno's plans for exploring Jupiter's ring system.

A cute video from the OSIRIS-REx mission in the style of "AsapSCIENCE" uses a whiteboard and stop-motion animation to separate asteroid fact from fiction.
In which I finally get around to writing about a paper published last August: Enceladus' plumes sometimes spout more and sometimes spout less, depending on where Enceladus is in its orbit. This discovery was enabled by Cassini's longevity at Saturn, and we'll be able to follow up on it, as long as Cassini is allowed to complete its mission.
