A baby Moon and aging Venus crescents are positioned close in the sky today, and lots of people are taking beautiful photos.
Planetary Radio: NEOWISE PI Amy Mainzer
NEOWISE has reawakened to discover more asteroids and comets. The mission leader thanks the amateur astronomers who follow up.

Now more than halfway through its journey from protoplanet Vesta to dwarf planet Ceres, Dawn is continuing to use its advanced ion propulsion system to reshape its orbit around the sun. Now that the ship is closer to the uncharted shores ahead than the lands it unveiled astern, we will begin looking at the plans for exploring another alien world.
With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa 2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.

2013 is drawing to a close, providing a nice opportunity to reflect on the outgoing year and look back at some of the highlights that we have experienced. Here are my top-20 OSIRIS-REx moments of this past year.
As promised, Lunar Reconnaissance Orbiter's sharp eyes spotted the Chang'e 3 lander and Yutu rover on the lunar surface on December 25. The hardware shows up as a few bright pixels throwing long, dark shadows, clearly visible in a before-and-after comparison.
NASA’s New Planetary Mission Woes
Budget cuts slow down the rate of new missions
NASA’s planetary science program depends on regular missions to solar system bodies to gather data. A combination of budget cuts and previous commitments to develop missions currently in the pipeline means that development of follow on missions may slow to a crawl. Van Kane looks at the current situation and NASA’s plans and then look at options the agency may consider if budgets remain tight into the next decade.

When Spirit and Opportunity landed in 2004, I was with the science team in charge of a group of high-school students called the Red Rover Goes to Mars Student Astronauts. We're coming up on the 10th anniversary of the landings -- what have those "kids" grown up into?

The International Astronomical Union has chosen the names Aegis and Gorgoneion for the two moons of the asteroid (93) Minerva. We decided to crowd-source the names, catching the attention of the public. Over the following year, I received a lot of emails with suggestions
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.
