In February 1958, when he was head of the cosmic ray group of the University of Maryland's physics department, he received a special commendation from President Eisenhower for "outstanding achievements in the development of satellites for scientific purposes." In April 1958, he was appointed as a consultant to the House Select Committee on Astronautics and Space Exploration, which was preparing to hold hearings on President Eisenhower's proposal for a new agency to handle space research, and a month later received the Ohio State University's Distinguished Alumnus Award. He became a full professor at Maryland in 1959, and was chosen that year by the United States Junior Chamber of Commerce as one of the country's ten outstanding young men.
