Partnering with our friends from The Planetary Society, the Space Generation Advisory Council (SGAC), whose members hail from all over the globe, is bringing you an update on our activities and something you can join in on—at least if you are a student or young professional aged 18–35.
An exciting new option to enhance NASA's OSIRIS-REx asteroid mission has been proposed by Steve Chesley at JPL. The ISIS spacecraft would impact asteroid Bennu to expose its interior structure to OSIRIS-REx.
Really cool movies from Jim Richardson propose to explain how the same physics of impact cratering can produce such differently-appearing surfaces as those of the Moon, large asteroids like Eros, and teeny ones like Itokawa.
Bruce Betts, Mat Kaplan, and asteroid tracker Robert Holmes on the Planetary Society Weekly Google Hangout. Mat discussed and showed pictures from his trip to the giant ALMA observatory and we'll be joined by asteroid tracker extraordinaire, Robert Holmes.
Emily Lakdawalla's guest this week was Applied Physics Laboratory asteroid astronomer Andy Rivkin. We talked about the menagerie of rocks in the asteroid belt, how many of them travel in pairs and triples, how some of them are surprisingly wet, and how much you can learn about asteroids using Earth-based telescopes.
While writing up the cruise-phase issues of the Galileo Messenger a couple of weeks ago, I came across a fuzzy montage of images of Ida that I had not seen before. So I decided to spend some time digging into the Planetary Data System to see if there were more images to be found. I found lots and lots pictures that I'd never seen before!
A frequently-asked question last week was: if asteroid 2012 DA14 is coming so close to Earth, why hasn't anyone taken any pictures of it? Now that 2012 DA14 has whizzed past us, we do finally have some radar pictures of it, but they still may not satisfy everyone.
Mostly the Universe stays unchanged for hundreds, thousands or even millions of years. There are some cases however when some things change really rapidly. Recently I observed one of these rapidly changing, transient phenomena, as asteroid called 2012 DA14. I work for Las Cumbres Observatory and we have been trying to observe this asteroid since 5 February.
Last week at a meeting of NASA's Small Bodies Assessment Group (SBAG), Han Li of the Chinese Academy of Sciences gave a lengthy presentation on Chang'E 2. Her presentation included a new sequence of photos from the December 13 Toutatis flyby.
