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...

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.
The Planetary Society and the Search for Extrasolar Planets

Almost since it was founded in 1980, The Planetary Society has been there for the search for other worlds.
A way-cool Cassini picture: rings, Titan, Dione, Prometheus
Posted by Emily Lakdawalla on 2005/10/19 07:12 CDT
I just noticed this picture on the Cassini raw images website. I love these "many worlds" pictures.
Animation from Cassini's approach to Dione

The images from Cassini's Dione encounter yesterday have started coming back, and there is a really cool set of 16 pictures of Dione and Rhea.
A new Cassini data release to the Planetary Data System
Posted by Emily Lakdawalla on 2005/10/06 09:29 CDT
Yesterday, this quarter's release of Cassini data showed up at the Planetary Data System (PDS). The PDS is the public repository for all of NASA's data.
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.

I've finally worked my way through all of the Hyperion images that were returned from the last flyby. It's a wonderful data set.
Another day, another natural disaster on Earth seen from space...

...but this one is much closer to home than Katrina and Rita were.
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.
A couple of pretty Cassini photos from this week
Posted by Emily Lakdawalla on 2005/08/20 09:06 CDT
First, here's a nice shot of Epimetheus, which was taken about a month ago.

Checking the Cassini raw images website, I found quite a few more images of Hyperion this morning. It looks like Cassini had a leisurely flyby of the little moon from roughly 700,000 kilometers' distance.

I was browsing the MESSENGER website just now, and found a neat photo. It's a picture of MESSENGER as seen from Earth when it flew by yesterday.

A couple cool raw Cassini pics -- and a break in the data
Posted by Emily Lakdawalla on 2005/07/19 04:56 CDT
I monitor the Cassini website to keep my eye out for cool pictures, and it's usually relatively easy to figure out what the spacecraft is looking at (rings, moon, Saturn, whatever). Sometimes, though, the images can be very confusing.
Deep Impact Data Surprises Scientists
Posted by A.J.S. Rayl on 2005/07/12 11:00 CDT
When Deep Impact crashed into the nucleus of Tempel 1 at 23,000 miles per hour on July 4, it sent a huge, bright cloud of stuff upward and outward from the comet, providing a spectacular image that is already assured a place in the space history books, and may well be seared into the brains of all those who watched the event.
Another gorgeous Deep Impact image

The team has just released a really pretty high-resolution view of Tempel 1 just 67 seconds after the impact.
News: Deep Impact Delivers the Science; Years of Work Ahead for Science Team
Posted by Emily Lakdawalla on 2005/07/04 02:21 CDT
"Our cratering experiment went very very well," reported impact scientist Peter Schultz in what may have been the understatement of the weekend. A first look at early science results from the mission suggest that while some events unfolded according to scientists' predictions, Tempel 1 provided many enticing surprises as well.
