He obtained work during the summers of 1962 and 1963 at North American Rockwell, a leading aerospace company. He worked in the company’s the space division and was assigned to perform computer analysis on the orbital mechanics and launch trajectories for rockets and missiles. Some of his work involved the Titan and Saturn rockets from the National Aeronautics and Space Administration’s (NASA) Apollo space missions and well as the NOVA missile.

In 1964, Alcorn applied for a research grant from NASA to study the concept of negative ion formation. He was awarded the grant and conducted his research from 1965 to 1967. At the same time, he was enrolled in the Physics program at Howard University and received a PhD in Atomic and Molecular physics in 1967. Finally, after tremendous success and researcher, George took a moment to focus on his personal life and got married to Marie DaViller in 1969.

Alcorn signed on with Philco-Ford, a division of the Ford Motor Company. Philco-Ford produced a wide array of products, ranging from car radio to television set. It also had an aerospace division which developed satellite tracking systems for NASA’s manned space program. Alcorn served as a senior scientist for the aerospace division. He later worked as a senior physicist for Perkin Elmer, a multinational technology corporation and then as an advisory engineer for International Business Machines (IBM). His relationship with IBM proved quite valuable in 1973 when he was selected to teach as an IBM Visiting Professor in Electrical Engineering at Howard University (eventually becoming a full professor). As if his schedule was not already busy enough, he also taught Electrical Engineering at the University of the District of Columbia as a full professor.

In 1978, Alcorn left IBM and joined NASA where he invented an imaging X-ray spectrometer which used thermomigration of aluminum. X-ray spectrometry is used to provide data which can be analyzed for a number of applications, including for obtaining information about remote solar systems and other space objects. He would receive a patent for the device in 1984. As a result of the significance of this work, he was the NASA/GSFC Inventor of the Year (GSFC is an acronym for the Goddard Space Flight Center, NASA’s first space flight center established in May of 1959). In 1986 he developed an improved method of fabrication using laser drilling.

Because of his success in his endeavors, NASA placed him in an administrative/management position as the deputy project manager for advanced development of new technologies for use in the International Space Station, Freedom. In 1990 he was named the manager for advanced programs for NASA/GSFC and in 1992 became the head of the Office of Commercial Programs at GSFC, helping to find commercial uses for the new technologies developed at GSFC. Later he ran the GSFC Evolution program which oversaw the development and running of the space station. In 1994, he oversaw a space shuttle experiment which utilized a “Robot Operated Material Processing System” to conduct the manufacturing of material in the microgravity of space.
