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.
A sharp-eyed amateur noticed two images of Titan taken 20 months apart from nearly exactly the same perspective, and they illustrate how the shifting of Saturn's seasons has brought change to Titan's atmosphere.
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.
It's a quarterly feast day for me: the day that the Cassini mission delivers three months' worth of data to NASA's Planetary Data System. Here's a few images processed from the October 1, 2012 data release.
A beautiful panoramic view of the varied rocks of Glenelg has been transmitted from Curiosity on Mars. But before going any further, it's time to run the first Martian sand through the soil sampling system.
An amateur-processed mosaic of some intriguing-looking broken rocks along Curiosity's traverse. They were intriguing enough to photograph with the Mastcam -- but not enough to stop and check them out, as Curiosity has already rolled on.
Oppy is opening an exciting new chapter in her adventure at Cape York. Having driven down to, over and past Whim Creek, she has now explored halfway down Cape York, to a promising fin-like ridge of dark rock.
