Frederick L. Scarf

Frederick Leonard Scarf (July 25, 1930 – July 17, 1988) was an American physicist known for his work in plasma wave physics and his leadership in developing space-based instruments to study the solar wind and planetary magnetospheres. After earning a PhD in physics from the Massachusetts Institute of Technology, he switched to space science in the early 1960s, working for TRW. Scarf played a central role in advocating for and designing plasma wave instruments aboard numerous NASA and international missions, including OGO-5, Pioneer Venus Orbiter, Giotto, ISEE-3, and the Voyager program spacecraft, where he served as the principal investigator for the Plasma Wave Subsystem (PWS). His innovative conversion of plasma wave data from the Voyager's PWS into audio recordings, called the "sounds of space" by journalists, gained public and scientific attention. A strong proponent of international collaboration, Scarf worked on joint projects with European, Japanese, and Soviet space programs, even during periods of official US policy restrictions. He died suddenly while visiting the Soviet Space Research Institute in Moscow. In recognition of his contributions, he was awarded with two NASA Exceptional Scientific Achievement Medals, and the American Geophysical Union established the Fred L. Scarf Award in his honor.
