New Horizons' Jupiter encounter is officially underway!

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.

Hayabusa has been riding an incredible wave of luck lately, resulting in the dramatic success of the sample grab last week. But it looks as though Hayabusa's luck may be running 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...

If I understand the various sources(and my somewhat vague memory) correctly, it now appears that Earth has rotated far enough to take the Deep Space Network station at Goldstone, through which Hayabusa has been transmitting, out of line with Hayabusa.

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.

Tak Iyori from The Planetary Society of Japan has sent us a couple of updates on the status of Hayabusa and the mission's plans for landing 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

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.

Hayabusa (formerly known as MUSES-C) is getting very, very close to its target asteroid Itokawa, and should be arriving soon!

I had very much hoped to be able to post an update about the Deep Impact mission this week, but it looks like my various sources are keeping very very quiet (or maybe they are just tired of me pestering them :)

We haven't forgotten about Deep Impact, but there's still no word on the crater size.

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.

There was a stage set up on the steps of the administration building, and the quad in front of it was filled with JPLers of all ages and descriptions. Rick Grammier and Don Yeomans introduced the band -- five guys, all members of the band since 1953 or earlier, still rockin' and rollin'.

So yesterday, after covering the Deep Impact press conference at JPL and recording for Planetary Radio, my husband and I drove to his parents' house for an Independence Day barbeque. When I explained the nature of the Deep Impact mission my mother-in-law exclaimed,
