Discoverer 20, also known as Corona 9014A, was an American area survey optical reconnaissance satellite which was launched in 1961. It was a KH-5 Argon satellite, based around an Agena-B. Discoverer 20 was the first KH-5 to be launched, however it failed towards the end of its mission, when its film return capsule failed to separate from the main spacecraft.
