Cosmos with Cosmos Episode 9: The Lives of the Stars
In which we are star stuff
This episode highlights the other big idea in Cosmos: that we are profoundly connected with the universe around us. Our constituent parts are forged in the bellies of massive stars; we exist through their deaths.

This week's show looks back over ten years of exploration by Spirit and Opportunity. Writer A.J.S. Rayl recounts the challenges encountered early in the mission, and how an outstanding team triumphed.
There was a lot of action on Chang'e 3 over the weekend! I have lots of pictures to share, including the highest-quality one I've seen of the rover on the surface, plus video of the rover making tracks on the Moon and a 3D view of the lander.
I've got some books to recommend on astrobiology, planet Earth and its living creatures, impact cratering, and Mars rovers.
Lots of people ask questions about how the Curiosity mission, and future missions, will forge ahead to begin with looking for evidence of past life on Mars. There is nothing simple or straightforward about looking for life.
Chinese state television broadcast a display of a Chang'e 3 lander image; the Yutu rover is awake; and LADEE reports a surprising non-detection of the Chang'e 3 landing.
If there's one thing I've learned after decades of studying the first human voyages to another world, it's that there is always more to discover about Apollo. Case in point: The Apollo 8 Earthrise photo that became one of the iconic images of the 20th century.

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.
