New Horizons is spending the summer traversing the asteroid belt. I haven't written a lot about New Horizons lately because the mission has been going so uneventfully well. But now I've got something to write about: data!!

After the political discussions of the morning, Mike Brown stood up to give the

The audience was rapt as Project Manager Jun'ichiro Kawaguchi stood up to give an introduction to the Hayabusa spacecraft and described the saga of the mission to date.

I received quite a number of emails containing suggested names for Pluto's moons -- thanks! I just sent all the suggestions to Alan Stern; here they are for everybody's enjoyment.

I just posted today's installment of Planetary Radio, in which Mat Kaplan gets an update on New Horizons from Principal Investigator Alan Stern-- check it out!

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...

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

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.

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

Since the discovery of 2003 UB313, larger than Pluto, there's been a lively debate going on in many places about what makes a planet. There's now an article in Nature talking about a proposal that would address the controversy

Today is the last day of DPS, and the first that has not had a press conference session at lunchtime, so I have a few moments here to do some catching up.

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.

Following last year's Potentially Hazardous Asteroid and a few other non-main-belt discoveries, I looked into what improvements I could make to more efficiently image the sky. The major advance involved the design of a 3-lens corrector comprising 2 stock lenses and a custom lens I made myself.

With its mission at Tempel 1 over, the Deep Impact spacecraft has altered its course in order to allow a future mission at another comet.

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.

The team has just released a really pretty high-resolution view of Tempel 1 just 67 seconds after the impact.
