Curiosity is a rover again at last! She was parked at the dune named Rocknest for 40 sols, from sol 60 through 99. On sol 100, she drove right on top of the dune, obliterating her five scoop marks. Then on sol 102 she took a good long, 35-meter drive so that she's now right on the edge of the

After a false start earlier this year, the first chunk of Dawn Framing Camera data from Vesta has finally made it to the Planetary Data System. As a first step to understanding the data set, I've built some index pages to these cool images.

This is a very large (19000 pixels square) mosaic of the fjords and glaciers of southern Greenland. I had been interested for a long time in experimenting with the processing of Earth satellite imagery just to get a comparison to the other planets.

After spending much of October driving around and taking pictures on Matijevic Hill, Opportunity hunkered down for Halloween and spent the holiday quietly, staying out of mischief's way and the Mars Exploration Rovers (MER) mission roved another month closer to its ninth anniversary of working on the surface of the Red Planet.

I'm directing a question at professional and amateur space scientists and educators: could I make slide sets that would help you educate the public about what's going on in planetary exploration?

Today I stumbled upon the Lunar and Planetary Institute's Lunar Sample Atlas, and was reminded of how much I love petrographic thin sections. They can make unassuming, cruddy looking rocks beautiful.

Curiosity has already spent more than three weeks at Rocknest, working through the very slow process of commissioning the sample handling systems. While parked, she's taken a couple of amazing photo mosaics.
