LPSC 2011: Day 3: Deep Impact at Hartley 2

Posted by Emily Lakdawalla on 2011/03/10 01:17 CST

Wednesday's sessions at the Lunar and Planetary Science Conference (LPSC) on the Deep Impact flyby of Hartley 2 were one of two that I was most looking forward to, the other being this morning's talks on Hayabusa's samples from Itokawa, about which I don't yet have any notes. I am again grateful to Franck Marchis and Andy Rivkin for sending me their notes on Hartley 2.

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."

High-res images of Tempel 1 from Stardust now arriving

Posted by Emily Lakdawalla on 2011/02/15 10:09 CST

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.

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.
