Deep Impact - by all accounts, a spectacular success, though tempered slightly by the exuberance of the outburst - reminded me of one of my favorite Siggraph entrants, from their 2001 bash, Horses on Mars.

A query towards artistic sorts: when you play on oekaki boards, do you use a tablet, or a trackpad? I'd like to see some results using just the latter, by way of encouragement.

Heh. Could be fun.. a Kevin & Kell RPG's due out shortly, from Double Exposure. And from the vaults of Spectrum games of old, Head over Heels, now freely available for OS X, Linux, Windows, and BeOS. As absolutely not mentioned by enteirah or eliki. ^_^

Interesting. Cartoon Network's announced their acquisition of Neon Genesis Evangelion. I'd recommend it highly, except it's likely to have the same, original English dub - and it's.. not one of the better ones. :-P

The iTMS is approaching 500,000,000 tracks sold - so, they're giving an iPod mini & fifty tracks to the buyer of every 100,000th, with the milestone purchaser getting "ten iPods of their choice to share with family and friends, an iTunes gift card for 10,000 songs and an all-expenses paid trip for four to see Coldplay on their world tour". You can also enter at no cost, by "sending an e-mail to Apple at itunes500@apple.com via the iTunes 'Tell a Friend' feature". It's open to "a legal resident of one of the 50 United States, including Washington, D.C., Austria, Belgium, Canada (excluding the Province of Quebec), Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland or the United Kingdom".

savak might enjoy this tale of one man, and his face, apparently an irresistible target for bats, as noted by kurtmrufa.

Witness the tragic fate of Polly Petalpants.

And winner of sending the 5000th message to my current inbox (which includes all the LJ notifications too) goes to loganberrybunny. No iPods, I'm afraid.. closest I can offer is the modem from a rev.A iBook. ^_^;
 
 
 
 
 
 
"And because the ejected plume casts a very clear shadow on the comet’s nucleus in optical images, it should be possible to determine the size of the plume's base - and that should correspond exactly to the size of the crater."

I was thinking the same thing. There's very clearly defined edges to the shadow in 3 consecutive frames before things fan out. Also, you can actually see the base of the shadow growing noticeably between the first frame where you see the shadow and the next frame. Too bad we will not see what things look like after things settle.
See, if they'd been thinking, they'd have had the probe equipped with a fifty foot pole behind it, with millimetric gradations for accurate measurements once it'd "landed". :) (I wonder how deep inside it wound up? Did the flyby craft have any radar?)

I wonder if they might want to try any secondary observations? Probably not, but checking up, it seems Tempel 1 has an orbital period of about 5.5 years.. by which time they might have finally extracted the last juice out of the current bones. :)
Maybe they should have simultaneously sent a second probe to orbit instead of crash? Ah well, next time. I am sure they will get more funding and popular support to crash more things, because that's so cool. ;-)

One thing I was thinking is that Tempel 1 already had a crater approximately where the impactor seemed to be heading. And by coincidence it seemed to be almost as wide as the shadow - so we may have bullseyed the existing crater rather than creating a new one. That would explain why the plume of ejecta was bigger than expected because the crust, if any, would have been somewhat thinner there and we got to the creamy centre a lot more easily than we thought. :-)
