This top-secret March 17, 1959 report examines how the United States could protect the secrecy of Project CORONA, the classified program developing satellites to photograph and gather intelligence over the Soviet Union and other areas. Officials were considering extending CORONA flights into 1960 and questioned whether the program’s true reconnaissance mission could remain concealed. Publicly, the related DISCOVERER satellite series was described as a research and development program involving satellite technology, payload recovery, environmental studies, and other scientific and military experiments.

The report warns that technical experts might correctly conclude that a classified reconnaissance program existed, making a convincing cover story essential. Rather than completely denying connections between DISCOVERER and reconnaissance development, officials proposed acknowledging its contribution to the publicly known SENTRY reconnaissance satellite program while continuing to conceal CORONA’s operational mission. The document recommends avoiding announcements about the number or schedule of future DISCOVERER flights and emphasizes preventing unauthorized disclosures. Officials express cautious optimism that CORONA could remain secret into 1960 but recommend periodically reassessing whether its cover remained effective. The report illustrates the extraordinary secrecy surrounding America’s earliest satellite reconnaissance efforts and the government’s attempts to disguise intelligence operations within publicly announced space programs.
