Doug Kaupa enjoyed a twenty-year Air Force career flying world-wide missions in various KC-135 platforms and as a test pilot. His last duty highlighted teaching at the Air Force Academy from 2012-2015. He relished teaching and watching when students understood and gained confidence in space topics covering orbital mechanics, spacecraft design, remote sensing, rocket propulsion and general engineering. He is currently working as a space analysis and exercise planner at US STRATCOM. On the side, he continues to teach as adjunct instructor covering algebra, physics, and engineering in classroom and on-line. The best approach to gain more students interest in space and engineering is to engage them in demos -- from angular momentum to lunar phasing -- where the student are conducting the demos, gaining confidence, and asking more science questions!
