Samos 4 was an American reconnaissance satellite which was lost in a launch failure in 1961. It was a film-return reconnaissance spacecraft, meaning that it returned images in a film capsule at the end of its mission. It was operated as part of the Samos programme. Samos 4 was the first of three Samos-E5 spacecraft to be launched; Samos-E5 satellites were based around an Agena-B, and carried a camera with a focal length of 1.67 metres (5 ft 6 in), and a resolution of 1.5 metres (4 ft 11 in).
