LPSC 2011: Day 3: Deep Impact at Hartley 2

Emily Lakdawalla • March 10, 2011

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.

365 Days of Astronomy Podcast: Stardust at Tempel 1

Emily Lakdawalla • February 28, 2011

Yesterday the 365 Days of Astronomy podcast aired my contribution, Stardust at Tempel 1: The First Second Trip to a Comet.

Stardust update: last image taken today

Emily Lakdawalla • February 24, 2011

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."

Sounds of Stardust, and a cool morphed Tempel 1 video

Emily Lakdawalla • February 18, 2011

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.

Some early scientific impressions of Stardust's Tempel 1 flyby

Emily Lakdawalla • February 16, 2011

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.

Highlights from today's Stardust Tempel 1 press briefing

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

Quick-and-dirty animation of Stardust Tempel 1 images through closest approach

Emily Lakdawalla • February 15, 2011

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.

High-res images of Tempel 1 from Stardust now arriving

Emily Lakdawalla • February 15, 2011

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.

First image from Stardust! ...but a delay for the close-approach ones

Emily Lakdawalla • February 15, 2011

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

Stardust flies by Tempel 1 in 5 hours, and I'll be watching!

Emily Lakdawalla • February 14, 2011

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.
