Lunar Orbiter 1 engineers and camera system, 1960s. The main payload of each Lunar Orbiter was the camera, designed to take photographs of the Moon. The payload structure was built around a pressurized shell holding Eastman Kodak's dual-imaging photographic system, which used a camera with wide-angle and telephoto lenses that could simultaneously take two kinds of pictures on the same film. The project engineers shown here are (left to right): Joseph 'Joe' Carl Mooreman (c.1942-1996), Israel Taback (1920-2008), G. Calvin 'Cal' Broome (c.1939-1993), and Lunar Orbiter project manager Clifford 'Cliff' H. Nelson (1914-2004). There were five Lunar Orbiter spacecraft, launched by NASA from August 1966 to August 1967. Photographed on 21 June 1967 at NASA's Langley Research Center.
