Anticipating the close flyby of asteroid 2005 YU55 yesterday, the Jet Propulsion Laboratory invited media to tour Goldstone, one of three facilities that make up NASA's Deep Space Network. I've always wanted to see these massive radio dishes up close, so I jumped at the chance!
Unless you've been living under a rock you've probably heard that there is a relatively large (400-meter) asteroid passing closer to Earth than the orbit of the Moon today -- in just a few minutes, as a matter of fact.
With little fanfare, the Dawn mission continues releasing a new picture from Vesta every day. This one is definitely my favorite among their recent releases, a closeup on one of Vesta's strange streaky bright craters.
It's been a very full day at the DPS-EPSC 2011 joint meeting. My day was less full than it might have been, because I overslept and missed most of the morning's session. I really needed the rest though so I think it was probably for the best!
Today they turned on the scientific fire hose at the Division of Planetary Sciences / European Planetary Science Congress meeting happening here in Nantes, France. My brain already feels full and I still have four more days!
Every day's image release from the Dawn spacecraft shows something on Vesta that is weird and cool and difficult to explain. The images come out with very little information describing what is going on to make those weird landscapes.
NASA funds regular meetings of scientists who work on different parts of the solar system to provide scientific input into NASA's future plans. These "analysis groups" are known by their acronyms, all of which sound kind of horrible, but none has quite as terrible-sounding an acronym as "SBAG," usually pronouced "ess-bag," the Small Bodies Assessment Group.
I had to wait until the kids were in bed and the husband fed last night before I finally had time to sit down and really look at the Dawn images of Vesta. And I still hardly knew where to begin. This brand new world is just so different than others I've seen.
Now that Dawn's close enough to Vesta, we're seeing absolutely spectacular detail and tremendous diversity across Vesta's surface. As usual it'll probably take me a while to bring together all the new information, so as a stopgap I'm going to post an awesome image and a rotation movie.
After covering 2.8 billion kilometers (1.7 billion miles) on its own, after traveling for nearly four years through the lonely emptiness of interplanetary space, after being bound by the gravity only of the sun, Dawn is finally in orbit around Vesta.
Yet another sharp-eyed reader (I love my readers!) pointed out to me that the German-language release on the MPS website about the latest Vesta image from Dawn included what looked like a tiny thumbnail of a color view.
