Dan Dumbacher, deputy director of the Exploration Launch Projects Office at NASA’s Marshall Space Flight Center in Huntsville, Ala., helps manage and lead overall development and integration of the Ares I and Ares V launch vehicle systems.

NASA’s Ares I is the launch vehicle that will transport the Orion crew exploration vehicle to space. Ares V will serve as NASA’s primary vessel for delivering resources to space — from large-scale hardware and materials to establish a permanent moon base, to food and fresh water needed to extend a human presence beyond Earth orbit.
