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.

Several news articles appeared in Indian media today about the upcoming launch of ISRO's Mars Orbiter Mission. Five instruments have been selected, and their delivery is expected in March.

Join Emily Lakdawalla and Casey Dreier for a chat with Jim Bell, a scientist who wears many hats. He's the team lead for the Pancam color cameras on the Spirit and Opportunity rovers; he's a member of the Curiosity science team; and he's the esteemed President of the Planetary Society's Board of Directors. We'll talk about the great science being done by both Curiosity and Opportunity, and about what's in store for the future.

Join us for our weekly Google+ Hangout Thursday at noon PT / 2000 UT. This week, I'm excited to have as a guest Sarah Hörst. Sarah is a postdoc at the University of Colorado whose current line of research involves experimental work on the complex atmospheric chemistry of Titan. She is also applying to be an astronaut!

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.
