QUOTE (elakdawalla @ Feb 15 2011, 09:00 PM)  I haven't seen anyone looking to see whether that flat tongue of material has expanded or retracted since DI saw it! I wanted to have a look at it, but the illumination doesn't help... |

QUOTE (machi @ Feb 16 2011, 01:25 AM) Byron: We have same idea! Quick and dirty attempt to find DI crater. Looks like big boulder from impactor images is gone. This item is in the center of impactor's last shot. http://deepimpact.umd.edu/gallery/ITS_PR4-PIA02129.html -------------------- |

I wonder if these results will change informed opinion on the effectiveness of attempting to use a nuclear device to divert an earth-bound comet.
The DI impactor imparted energy equivalent to around 5 tonnes of TNT, but we can't even see the resultant damage, from close range and with a pretty decent camera. |

So remember how there were supposed to be 5 images near closest approach that were queued first for transmission to Earth? Well....about that....it seems they somehow wound up being the LAST transmitted. That's the reason for the most recent delay to the press briefing. Ooops!

QUOTE (Explorer1 @ Feb 15 2011, 02:11 PM) 150 meter crater, with mound! I haven't been able to tune in to NASA-TV, but did manage to fiddle with one of the new images in Photoshop. Just as a fun exercise, I want to see if I'm even close to seeing the spot. Just so folks know, THIS ISN'T AN OFFICIAL PHOTO. Just my fiddling. Looks like a dark spot with radial stuff and material draped over an edge. Rick

Before and after comparison from the NASA website: http://www.nasa.gov/mission_pages/stardust...a/Schultz4.html
It seems to have demolished a small peak. |

That's what I figured it was too, Rick. Far more subtle then the natural craters.

I just saw the image of the crater they showed at the press conference. By George, I think I got it.

Looks to me like the area in question has changed quite substantially, but I cannot say what it's changed into. Looks more like a tiny crater with a raised rim to me, but it's hardly clear. |
