KH-5 2 [USAF]
KH-5 (Keyhole 5, codenamed Argon) was the area survey component of the Corona program.
The Argon camera (also called Corona-A), a single frame camera, was integrated with standard Corona hardware like the return vehicle (SRV). The ground resolution of KH-5 was ca. 140 m. The SRV and the camera remained fixed to the Agena-B stage, which provided three axis control and propulsion during the mission. The SRV was deorbited using its own small solid rocket motor.
Only missions #5 and #7 produced usable images, the others failed due to various reasons (#3, 4 launch failures, #1, 2 on orbit failures, #6 failed on recovery)
Later KH-5 missions were based on the Agena-D stage.
Some satellites carried secondary payloads mounted on the satellite:
