Overview
During the Apollo 11 mission in July 1969, Bales worked in NASA’s Mission Control Center in Houston, Texas, where he monitored the guidance, navigation, and control systems of the Lunar Module “Eagle.” His real‑time analyses and decisions contributed to the successful descent and landing on the Moon. After the Apollo program, Bales continued a career at NASA, serving in various managerial positions, including roles related to the Space Shuttle program and later as a senior executive within the agency.
