Recently, space image processing enthusiast Thomas Appéré noticed that Curiosity had taken five photos of exactly the same spot on the rim of Gale crater, identical but for being taken at different times of day. That spot was due north of the rover, so the rising and lowering Sun illuminates the rounded hummocks of the crater rim differently from early morning to early afternoon.
January 24 was the 30th anniversary of the Voyager flyby of Uranus. Uranian moons have been on my mind ever since New Horizons sent us close-up images of Charon. On the occasion of the anniversary, Ted Stryk produced latest-and-greatest versions of the Voyager views of these worlds.
Finally! It has been a long wait, but so worth it: the Rosetta OSIRIS science camera team has delivered the first pile of data from the rendezvous with comet 67P to ESA's Planetary Science Archive. I have spent a good chunk of the last three days playing with the data, and it's spectacular.
