For anyone who won't be outside looking through their telescopes, and is interested in following the live coverage of the impact online (and playing with the raw images as they come down!) feel free to join us in irc:
#space on irc.freenode.net With so many cameras pointed at Tempel 1 tonight (many having promised prompt release of images), it should turn out to be a very active and exciting night! |

Thanks Phil! Also very useful (to me) gleaning the press conference at JPL.

My guess is that the CCD imager is read in 4 different parts, one after the other. So the background levels will not be same, as some parts are exposed longer than others.
This is a guess, but I'm shure that with calibration the images will be fine. -------------------- _______________________

Idiot that I am (no agreements, please), I forgot to take into account the main craft's deflection maneuver. When DI took that publicly released photo of its Impactor, it was more like 240 km away -- not 1.2 km away. That means that, just to show the shape of the Impactor, the released photo must have been taken with the HRI. Maybe they HAVE found a satisfactory way to deconvolve its photos. (They said at this morning's press conference that it would take "between 6 hours and 2 days" to deconvolve the HRI photos of the comet itself for public release.)

In this image the tag at bottom says "VISMRI" which would indicate to me that it was taken in the visible by the medium res imager..... |

You may be right. If so, however, then -- at 240 km range -- MRI's resolution should be only about 2.4 meters, which means that the Impactor should fill only 1 pixel in it.

UGH!! !! Is anyone else trying to watch streaming NASATV? As usual duing these times it is virtually useless. Spending 90% of the time buffering and 10% of the time in choppy garbled video. Why don't they at least try to experiment with distributed P2P streaming video?! And I have digial cable but do they carry NASATV? noOOooo. but I do have about 300 channels of ginsu knife hawking home shopping channels. Sigh. Oh well.

Well
http://www.napacomfort.com/mars/nasa_feed.html I'm using an AMES real player feed. it's a slow frame rate, but the actual quality of the video is good, and the sound is excellent - no stutters as of yet. The WMP feed from nasa.gov stutters all the time - very annoying. Doug |

I'm using the windows media stream from the NASA TV Landing page.
It's perfect, sound and pictures. -------------------- Turn the middle side topwise....TOPWISE!!

does the Deep Impact site have live HRI updates? I can't seem to see anything different...

Nope - HRI stuff is being kept back so they can process it
