Monday was the big Curiosity day at the fall meeting of the American Geophysical Union. A morning press briefing was followed by an afternoon science session. I traveled to San Francisco briefly just to attend those two events. Here's my notes on the first science reports from the mission.
The Planetary Society has a new weekly Google+ Hangout time slot, Thursdays at noon PT / 1800 UT. This week, Casey Dreier and I talked about the Curiosity kerfuffle and NASA's future rover plans. Here's the archived recording.
Now that Casey has explained the budget implications of yesterday's 2020 rover announcement, and The Planetary Society has issued a formal statement, I thought it was time for me to talk briefly about science.
With all the hoopla surrounding the unknown results of the first analysis of a soil sample by Curiosity's Sample Analysis at Mars (SAM) instrument, I thought an explainer would be useful. What is SAM, what is it designed to measure, and what is the nature of its results? Here you go.
Water ice at Mercury's poles? That's crazy, right? The MESSENGER team has made a very good case that radar-bright material seen by the Arecibo telescope is, in fact, water ice, covered in most places by a veneer of dark organic material.
Remember the amazing photo of Saturn's north pole that I posted yesterday? Now, thanks to an amateur image processor, it moves, and the motions of the individual clouds within the belts are mesmerizing.
