Definition
Andrew J. Stofan was an American aerospace engineer and senior NASA official recognized for his contributions to liquid rocket propulsion and the development of high‑performance rocket engines.
Overview
Stofan’s career spanned the transition from the National Advisory Committee for Aeronautics (NACA) to the National Aeronautics and Space Administration (NASA). He joined NACA in the 1950s, where he specialized in rocket propulsion research. After the formation of NASA, Stofan played a pivotal role in the development of the RL10 engine, a pioneering liquid‑hydrogen/liquid‑oxygen rocket engine used in upper‑stage applications for the Atlas, Saturn, and Delta launch families.
In the 1970s, Stofan held senior management positions at NASA’s Lewis Research Center (now the Glenn Research Center), eventually serving as its director. Under his leadership, the center advanced research in propulsion, power generation, and materials science, supporting programs such as the Space Shuttle Main Engine (SSME) and later the Space Launch System (SLS).
Stofan retired from NASA in the late 1980s after a career that earned him multiple honors, including the NASA Exceptional Service Medal and recognition from professional societies such as the American Institute of Aeronautics and Astronautics (AIAA).
Etymology/Origin
The surname “Stofan” is of Eastern European origin, likely derived from Slavic languages. The given name “Andrew” is the English form of the Greek name Andreas, meaning “manly” or “brave.” The middle initial “J.” stands for “James,” a common English middle name.
