Mission Details

KH-1 1 (Discoverer 4)

The KH-1, the inaugural endeavor in the Corona program, aimed to construct an optical reconnaissance satellite. These satellites, collectively known as Discoverer, were the precursors to modern reconnaissance technology. The KH-1 payload comprised the C (Corona) single panoramic camera and a General Electric return vehicle (SRV), enabling data capture and retrieval from space. The satellite utilized the Agena-A upper stage for orbital maneuvering and control. Upon mission completion, the film return capsule employed its own retro motor for deorbiting, facilitating mid-air recovery by specialized aircraft.
