Named in honor of David F. Bender, whose analytical techniques and innovations are widely used to evaluate potential space missions to minor planets. A pioneer in the generation of trajectories for both flyby and rendezvous missions, and now a septuagenarian, he is still actively involved in related work at the Jet Propulsion Laboratory, where he has long been a member of the Advance Project Group in the Mission Design Section.
