Deep Impact Squiggles...... 'secret'
i've got to take a break from this work/meeting stuff. i'm on my last day here and i've spent most of it redo-ing figures for one of the papers...... it's been fun and interesting and all that crap, but a bit exhausting. anyways, here's a few pics i grabbed from the DI website cause i spent a lot of time looking at them over the last couple days.


so this one is the time sequence from the medium-res-imager camera onboard the flyby craft. we hit obliquely (inclined 30 degrees) so that the impactor dug in a ways from the first flash point and made a really cool ejecta curtain. we spent a lot of time listening to pete talk about his cratering experiments (including shooting eggs at hundreds of mph.... talk about fun) check out his vids on the DI site here

and then the temperature map. the interesting thing about this is that the hot part is directly under the sun. i know. you're thinking, why is this interesting. the sun's hot right? i was a little surprised that they cared about this so much. but, then a little thought comes in - it TAKES A WHILE to heat things up. there's this concept of 'thermal inertia' that's important. the hottest time of day isn't noon. its about 2 or 3pm on earth cause the air takes time to heat up. the comet was actually reaching it's highest temperatures a little bit BEFORE local noon. this is extremely weird if you consider it...... there are lots of things you can do with that.

ok, enough geek stuff. i'm guessing that those who were curious about why somebody spent two grand to have me come here for three days are still hopelessly mystified.....

I'm glad you didn't try to do the 'west side' fingers in that shot =) too much stuff in the hands, huh?
So why would the comet be heating up early? How does that work?

Are you sure you hit a comet it looks like a potato. For all I know you heated a potato in the microwave and you've actually spent the last 2 years just surfing in Hawaii and not going to school.Say hi to Don Ho Go see the show at the outrigger waikiki and it's sos society of seven
