This description of asteroid 2867 Steins is based upon an article published in the January 8, 2010 issue of Science by H. Uwe Keller and numerous coauthors and on a related press release.

Triple asteroid 1994 CC rotation animation

From the "just plain cool" department. I love animations of planetary images and I love radar images of asteroids -- so this animation is doubly cool.
Big News for Hayabusa: It wasn't hovering, it landed!!
Posted by Emily Lakdawalla on 2005/11/23 07:21 CST
Remember how Hayabusa was virtually still for 30 minutes? JAXA is now saying that Hayabusa actually touched down -- and more than that, they may even have a sample.

Hayabusa reached an altitude of about 560 meters above Hayabusa at 17:30 UTC. And at 18:00 UTC they are at 500 meters. This is still farther above the asteroid than the asteroid is big...there is still a long way to go before Hayabusa touches down...
Getting ready for Hayabusa's touchdown

In a further update on Hayabusa's status, we have been contacted by Kazuya Yoshida of the Space Robotics Laboratory at Tohuku University. Yoshida reports that the touchdown is now planned to take place "in early morning of November 20 (Sunday) JST", which would make it late Saturday evening UTC, or Saturday midday here in California.
Another Hayabusa update: small delay

There has been a delay of just about a day in JAXA's plans for landing Hayabusa on Itokawa.

These photos pretty much speak for themselves. They are amazing. Hayabusa saw its own shadow on Itokawa, and took a photo of the released target marker.
A piece of a new picture from Hayabusa
Posted by Emily Lakdawalla on 2005/10/04 06:21 CDT
The Hayabusa mission has proven to be a bit of a tease -- they were releasing lots of images to the public as they approached asteroid Itokawa, but once they arrived, the image releases shut down entirely. There is finally a little postage stamp of an image captured by Hayabusa at "home position," only 7 kilometers from the asteroid, compared here to a picture taken from "gate position," 20 kilometers away.
An animation of Itokawa from Hayabusa

This lovely animation of Itokawa represents 20 individual images taken between 18:10 on September 5 and 00:30 on September 6, from a distance of less than 700 kilometers away.

This morning, asteroid 4179 Toutatis was so close to Earth that simultaneous observations from two telescopes in the same country could show parallax that is obvious even to the least experienced observer. The two telescopes belong to The European Southern Observatory and are located at La Silla and Paranal in Chile
