Yesterday at the American Geophysical Union meeting, the Curiosity science team announced the discovery of a mineral never before found on Mars. The finding was the result of a fortuitous series of events, but as long as Curiosity's instruments continue to function well, it's the kind of discovery that Curiosity should now be able to repeat.
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.
ESA announced today a new website at which the OSIRIS team will now be releasing images on a regular basis -- at least one per week -- and they will be recent. Even better news, all OSIRIS data taken through September 16, 2014 has been handed to ESA and its release is expected next week.
JAXA had a press briefing today to confirm the successful arrival of Akatsuki into Venus orbit. It's been a long time coming: today's announcement came twelve years to the day after Japan had to abandon efforts to put Nozomi into Mars orbit. They released lovely images and discussed future plans.
This is it: Akatsuki's final chance at Venus orbit insertion. The rocket firing should begin on December 7 at 08:51 Japan time (December 6 23:51 UT / 15:51 PST) and last for 20 minutes. It will take two days for JAXA to determine whether the orbit has been changed enough for Akatsuki to stay at Venus.
I just love photos of Earth from planetary missions -- especially if they manage to get Earth and Moon in the same shot, as Hayabusa2 did on November 26.

The third entry in my series of blog posts about Favorite Astro Plots contains one of the biggest discoveries from the Apollo program -- as well as one of the biggest questions in planetary science. The chart was nominated by planetary scientist Barbara Cohen. It has to do with the ages of surfaces on the Moon.
Continuing an annual tradition, Emily Lakdawalla reviews children's books about space -- what's out there, how we explore, and why. Many of the books on this list aren't just for kids!

A panel of outside experts reviewed the design of the Mars 2020 rover's color cameras, and approved the progress of Mastcam-Z. It still exists only as an idea in the cloud, but it's one significant step closer to being sent to Mars.
If you were to download the entire catalog of photos taken at Saturn to date by Cassini and then animate them like a flipbook, how long would it take to watch them all pass by? The Wall Street Journal's Visual Correspondent Jon Keegan has your answer: nearly four hours.
