I thought it was time to start a new thread on Stardust's flyby of Tempel 1, the first time a comet receives a second visit from a spacecraft one perihelion later.
There was an interesting story about this on Spaceflight now recently http://www.spaceflightnow.com/news/n1012/23stardustnext/ note that the flyby will be around 23.30 eastern time on 14 February, so thinking in GMT it will not happen on Valentine's day. Stardust should have started imaging Tempel 1 twice weekly in mid-December, but there is nothing yet on the mission site http://stardustnext.jpl.nasa.gov/index.html see also http://stardustnext.jpl.nasa.gov/mission/m...tatus10_q4.html for updates on the mission status |

Apparently, they intended to download the closest approach images first, but for some unknown reason, the images are coming in in the order they were taken.
edit: Will have press conference tomorrow to show closest approach images. edit2: Tomorrow being... in the morning -------------------- -- Hungry4info (Sirius_Alpha)

They're saying ~6hr wait to get the closest approach images. Looks like it's time for bed. (And great consolation for all the folks who couldn't stay up!)

Flicking between them shows some vagueness... Still to early to say for sure. EDIT: several more: oh this is excruciating! Looks like some vague circle. Dare I say it's the crater? Going to be no matter what now. Press conference delayed so at least I'll get some sleep. http://www.nasa.gov/images/content/516881main_n30008te01.jpg |

Hmmm tantalising, but still too early to say whether the same hemisphere's in view..

I don't know, the sharpened images Astro0 posted really suggest to me we're seeing that crater and crescent feature near the impact site, it's just that the comet is rotated slightly. If only my Photoshop at work didn't crap out on me...
If that is the case, it's also pretty obvious any resulting crater isn't huge. -------------------- |

They are proberbly asleep, or keeping them back for the news conference. It's 4:16 am at JPL.
Also the spacecraft isn't sending the pictures down in the order expected. |

The broad end of the nucleus seems to be facing Stardust in the photos. I think that this means that the plan to take a detailed photo the Deep Impact crater just before closest approach has succeeded.
On the TV coverage I saw someone pick up the comet model and point to the fat end of the nucleus. The bearded project scientist responsible for determining the rotation of the comet then vigourously nodded his head in agreement. This is encouraging. |

I tried to make crossed-eye stereogram with second and last pictures (after rotation/rescaling/sharpening processings):
