Looking ahead to spacecraft activities in 2013

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.

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.

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.

Regular readers of this blog will find the content of today's 365 Days of Astronomy Podcast familiar, because it's an update on what the solar system exploration spacecraft are up to, based on my monthly "what's up" updates.
Chang'E 2 update: primary mission successful

For months I've had no information about China's Chang'e 2 lunar orbiter for my monthly "What's Up" updates, and that's finally changed.
What's up in the solar system in March 2011
Posted by Emily Lakdawalla on 2011/02/28 02:43 CST
I don't think there's any question what the big event of this month will be: MESSENGER is finally, finally entering orbit at Mercury on March 18 at 00:45 UTC (March 17 at 16:45 for me).
