According to the Stardust website, the spacecraft has continued taking navigational camera images of Tempel 1 since last Monday's flyby. But "This will end with a Navcam calibration that will take place [today]. This will be the end of the official Tempel 1 encounter activities. Planning is under way for the decommissioning of the spacecraft."

Here's two more items from Tuesday's flyby of comet Tempel 1 by the Stardust spacecraft to add to my previous roundup of Tempel 1 data. The first represents data from a dust counting instrument, portrayed as sound, and the second is a terrific morph animation of the flyby produced by Daniel Macháček.

I've spent a day with the Stardust images from Tempel 1, and had a chat with co-investigator Jessica Sunshine, so here are a bunch of images with some preliminary scientific commentary.

It was a very happy science team at this afternoon's press briefing following the Stardust encounter with Tempel 1.

Here's a quick-and-dirty animated GIF of the 39 images of Tempel 1 that have arrived on Earth so far from Stardust. I've put a big watermark on this animation because it's not a final product.

I really didn't expect these images to look so good! I'd prepared myself for blurry images and a lot of squinting to try to match up features in pictures between Deep Impact and Stardust views of Tempel 1, but in fact the resemblance is obvious and you can clearly see that they successfully imaged the area in which Deep Impact's Impactor craft collided with the comet.

Here it is, the first image from Stardust of Tempel 1 during the close-approach phase!

Stardust is very close to the last major act of its mission: the flyby of Tempel 1, which will take place at 20:40 PST (04:40 UTC). Here's a summary of the recent and current status of the mission, and how to follow the events over the next 24 hours.

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.

"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.

Here in Von Karman auditorium at JPL, as they get ready for the press conference, they are playing "Rock Around the Clock," by Bill Haley and His Comets. Very appropriate! The press panel is mostly familiar: Andy Danztler, Rick Grammier, Shyam Bhaskaran, Mike A'Hearn, and Pete Schultz.

The Deep Impact mission seems to have produced an impact crash beyond the expectations, but not the hopes, of the science team.

I woke this morning to find a press release in my Inbox that said: "One hundred and seventy-one days into its 172-day journey to comet Tempel 1, NASA's Deep Impact spacecraft successfully released its impactor at 11:07 p.m. Saturday, Pacific Daylight Time," or 06:07 UTC.
