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

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 Doug |

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.. -------------------- Space Enthusiast Richard Hendricks

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.

holy...I thought the tv camera defocused, but those were actual HRI raw images deconvolved real-time!?! Those raw images looked like crap...

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

Last TCM calculations suggest again, 2ish m/sec

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. |

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