Well - impactor TCM 1 went well - <0.3% error and it's on course for a nominal impact time. PI has suggested that the comet is Banana shaped and we're going to hit the end of it which looks a little triangular ohmy.gif

A rather rough and ready HRI picture on NASA TV - looks a bit like a distant startdust image.

TCM 2 is in progress - estimated to be 40ish seconds long, be around 2.2m/sec and use around 0.3kg of fuel.

Sounds like someone was concerned about microradians being too high, I assume it's a turn rate...

I assume this is the calculated pointing error for the MRI on the Impactor.

Pictures on NASA TV look amazing from the HRI! Couldnt help myself laughing, there's a great big impact crater like feature just about where the impactor will be targeting smile.gif

Figures...Nasa TV is showing images of the HRI. I see a crater!!!

Their lame Deep Impact IMage Viewer doesn't show CRAP.

More like an eggplant than a pickle..

Did I get that right? They're doing (near) real-time deconvolve?

..... >6Kg fuel remains, plenty for final targeting.

Yep. On their laptops, no less. I guess Mike's comment that it would take 2 days is a bit of a schedule stretch. Then again their quick & dirty deconvolve might not be as good as a take your time Dc.

For those with access - Sky News is carrying NTV as one of their multi-screen feeds

Final ITM (ITM 3) occurs in <3 min. As I understand it, on board autonav targeting data indicates agreement with ground track (radio) data is within <1Km....

I have to say this is considerably more exciting than I had expected. smile.gif

"Near real time" my butt. The Image Viewer is a waste of bandwidth.
