Introducing PlanetFour
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.
How GRAIL will meet its end
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.

It is always thrilling to see relics of human exploration out there on other worlds.

Lovely crater turns up in MoonZoo; 2 million images classified, lots more Moon left
Here's a very pretty picture to start off the week: a really gorgeous fresh crater on the lunar farside. There's nothing particularly unusual about this crater; it's just recent and fresh so there's a mesmerizing amount of detail in the feathery patterns of the ejecta that fans outward from it.

What's up in the solar system in April 2011
April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.
