PROFILE: DAN DURDA:
Cave Diving on Asteroids
Robert Irion
BOULDER, COLORADO--Planetary scientist Dan Durda flies high, dives deep, and wants to be one of the first to touch the surface of an object beyond the moon. At age 36, Durda is best known for creating painstaking models that have helped reveal how collisions shape the evolution of the asteroid belt, from the largest objects to the tiniest grains of interplanetary dust. He loves plumbing the depths of water-filled caves, and he is an accomplished space artist.
