Dennis Hasson received his Mechanical Engineering BES from The John Hopkins University, his Aerospace Engineering MS from Virginia Polytechnic Institute, and his Engineering Material Ph.D. from the University of Maryland. Hasson worked at NACA-NASA at Langley Research Center, as well as the Goddard Space Flight Center. Hasson's work started with experimental aerodynamic studies on advanced aircraft, such as the X-15 and Mach 3 transport. In March 1959, Hasson was assigned to the Aerodynamics Group at Langley Field. That group was responsible for the aerodynamic performance of the manned space vehicle in the earth's atmosphere. Hasson was responsible for the wind-tunnel program for the Mercury project and he and two coworkers received a patent for a manned reentry vehicle for planned lunar missions. In 1961, he became involved in advanced control thruster and power systems for deep-space probes, using advanced materials including fabricators and metallic, polymeric and ceramic materials. He is a Fellow of both ASM international and ASME Internal. He received the Meritorious Civilian Service Medal, and was Pi Tau Sigma USNA Chapter Teacher of the Year. He is currently a Professor at the US Naval Academy in the Mechanical Engineering Department.
