Daniel Durda (SWRI): Overview talk. The asteroid belt is a fossilized collisional system - the size distribution (particularly waves in size dist) tells us about the past. Dust production is "spikey": lots right after a big collision.
Lots of work on Chicxulub impact, where does debris land? (Back into atmosphere, heating it up, burning everything)
Used Ames gun to smash real meteorites and study dust from them.
