Nothing reflects the romance of deep space exploration more than the evocative names of places on the planets and moons.

They look so similar they can be hard to tell apart, but each hides its own mysteries.

China's lunar lander and rover are undergoing some of their last major tests and so are nearly ready for launch.

No mission to Europa, diminished funding for outer planets missions, a small bump to small spacecraft missions, and an increase for asteroid detection are part of the White House's proposal for NASA in 2014.

Dispatches from five different worlds--all sent by robotic spacecraft on the same day.

Why spend effort and scarce resources on space exploration when we have so many problems here at home? Turns out, there are some pretty good reasons.

We welcomed Sarah Noble to our weekly Google+ Hangout. Sarah is a lunar geologist and a civil servant working in the Research & Analysis program at NASA Headquarters, and has recently been named Program Scientist for the LADEE lunar mission.

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.

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.

All of the information I could track down on China's planned Chang'e 3 lunar lander and rover, including videos and a brand-new artist's concept of the rover rolling across the Moon.

2013 is going to be a busy year in space exploration. Two missions launch to the Moon (LADEE and Chang'E 3), and another two to Mars (MAVEN and India's mission). Curiosity should drive to the Mountain, and Opportunity to the next site on Endeavour's rim. Cassini will be seeing rings and Titan. Others should continue routine operations, except maybe MESSENGER, whose fate after March is not yet decided.

My collage of all the asteroids and comets visited by spacecraft is probably the single most popular image I have ever posted on this blog. I've now updated it to be in color and to include Toutatis.

The Chang'E 2 mission flyby of Toutatis succeeded in acquiring images. Oh my goodness, did they succeed. These, in combination with the incredible radar images still being acquired from Goldstone and innumerable optical observations, make Toutatis one of the best-studied asteroids in the solar system.

The twin GRAIL spacecraft are nearly out of fuel, and are being directed to a controlled impact near the north pole on the near side of the Moon on December 17. Before the end, though, they did some cool things, including flying within 2000 meters of mountaintops, and catching video of Lunar Reconnaissance Orbiter in flight.

Near-Earth asteroid 4179 Toutatis will be passing within 7 million kilometers of Earth on December 12. Both radio telescopes and the Chang'E 2 spacecraft will be acquiring images.

An update on China's second lunar orbiter, Chang'e 2, which is now heading for asteroid Toutatis.

Welcome to the monthly roundup of our solar system's envoy of electronic explorers! All eyes are on Curiosity as it approaches Mars this weekend. Who will lend support at the Red Planet?

I have a couple of updates on my post from yesterday: confirmation that Chang'E 2 is indeed gone from L2, and more specifics on encounter dates with Toutatis.
