Discoverer 37 was intended to be operated in a low Earth orbit. It had a mass of,[4] and was equipped with a panoramic camera with a focal length of, which had a maximum resolution of .[5] Images were to have been recorded onto 70mm film, and returned in a Satellite Recovery Vehicle at the end of the mission.
