Keith’s note: From NASA GRC: On April 12, 2023, the NASA Glenn Research Center (GRC) — and the nation — lost a remarkable unsung hero of the NASA’s early expendable launch vehicle program. John (“Joe”) Nieberding was one of the GRC’s most accomplished and highly regarded engineer/supervisor/executive leaders. A retired division chief, he held leadership roles in Atlas/Centaur, Titan/Centaur, and Shuttle/Centaur launch vehicle programs during development, integration, and day-of-launch at the Cape.
