have been watching the live stream from Lockheed Martin Space Systems, and has been good.

the craft has taken over 70 images of the comet, but will be a few hours before we can see them, by the looks.

Hey Liz;

Are you taking bets on whether we'll be able to see the impactor site ?

I'm looking forward to this .. exciting.
:)

If the impact crater is visible it'll be very interesting to see if it's now a source of jets. I could imagine it to be so, with fresh underground material recently exposed - but also equally fascinating if it isn't.

1st image has arrived :thumbsup:
Apparently they are not coming in the order they expected, so closest approach image is still 6 hours away...

So here are the images (http://stardustnext.jpl.nasa.gov/multimedia/tempel1_images.html) ..

(I can't spot the impactors site .. )

Haven't seen any briefings yet …

Cheers

(Fyi) ..
I've summarised some of the detailed snippets from the press conference in Science Forum post here (http://www.iceinspace.com.au/forum/showthread.php?p=688226#post688226) .
The press conference video is here (http://www.ustream.tv/recorded/12717282).

They've isolated the impactor site - 150 m across with a central mound;

- lots of erosion/sublimation observed from images;
- spacecraft took about 12 hits of about 1mm sized impacts as well as another 5,000 hits of smaller size;
- impact zone concluded to have been 'weak, fragile and self-healing';
- 27:07 minute mark shows the comparison image between the initial impact and the recent 2011 image. (They haven't published it on the web, just yet);
- smooth surface flows observed, caused by volatile sub-surface gas eruptions with surface material flowing downhill (due to comet's own gravity);
- the original ejecta material "was all ice" - Schultz (at the 29:00 min mark).

Cheers

Thankfully the mission appears to have gone more smoothly than their press conference! :lol:

For those who have not yet watched the video and as Craig kindly itemizes in
his summary, the Deep Impact crater image comparison is eventually shown at the 26:50 second mark.

Nice to hear Kelly Beatty's friendly voice with a phone-in question from Sky &
Telescope. The Aussie contingent who made it to TSP in 2007 got to
meet him.

It is remarkable how little 78MB seems by today's standards but hopefully that
hard-won data will prove fruitful for investigators for many years to come.
Great stuff. :thumbsup:

Gee they're quick ! …

Wikipedia has before and after shots (http://en.wikipedia.org/wiki/Stardust_(spacecraft)#Encounter_wit h_Tempel_1) of the impactor site …

Faster than a speeding bullet !!
:lol::)

Ohhh yes they are!!!!



Tis a bit Fuzzy but one can see .....well sorry but I thought the black hole to the upper left of the arrows would look more like an impact center to me....:P
Just curious Craig.... were they aiming at that point?(the impact epicenter)
Waiting for the Hi Res shots....

…That's weird … the link Bartman included in quotes in his post seems to not have the impact shots but my original post #12 does have them !!

I think Bart must've edited my link !

Here are the before and after images (http://en.wikipedia.org/wiki/Stardust_(spacecraft)#Encounter_wit h_Tempel_1).

PS: The impactor had a 30 degree trajectory and they explained the black spot as scooped up debris (I recall?).

Heya Craig....
No I didn't edit ure post....:screwy:
Simply cut and paste...the multi quote thingy......

I WOULD NOT DO THAT!

Can You explain what I might have done wrong?
