Robert Jedicke has been fascinated by collisions of one form or another for most of his careers.  From studying the results of slamming sub-atomic particles together at Fermi National Accelerator Laboratory in the suburbs of Chicago, IL, to colliding on the football field in college at the University of Western Ontario, Canada, and during a brief tryout in the professional Canadian Football League with the B.C. Lions, to ensuring that Earth does not suffer an impact by a large asteroid like the one that killed the dinosaurs 65 million years ago.  He is now an astronomer at the University of Hawaii’s Institute for Astronomy where his current work involves looking for mini-moons of the Earth and determining how much water might be mined from asteroids to support space exploration.  He has discovered two comets and an asteroid is named after his family.
