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

Figures...Nasa TV is showing images of the HRI. I see a crater!!!
Their lame Deep Impact IMage Viewer doesn't show CRAP.

Did I get that right? They're doing (near) real-time deconvolve?
..... >6Kg fuel remains, plenty for final targeting.
hendric
Jul 4 2005, 05:28 AM
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.

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.

Consdering they're compensating for a really low albedo, "bright" is a pretty relative term.

screengrabs from NASA TV
some initial interpretations: the circular features appear to be positive relief features, maybe low mesas. Combined with the scarps nearby, perhaps (and I know this was suggested for Wild 2) that cometary material is ejected from the scarps, eroding them back.
Compared to the simulation animation shown often in the last few days, the impact ejecta is mostly traveling laterally away from the impact site. the animation showed ejecta going straight back. Alex Dessler, who watched the event with me, thought he noticed the formation of several rays during the impact

What time GMT is the press conference on?
I don't trust my time conversion after I got up an hour earlier that I needed this morning.
It's gonna be a looooong day. Totally worth it though.

Edit: Ahh, never mind, it's "momentarily" apparently....
