NASA/Jet Propulsion Laboratory, Pasadena.- Mars, a collection of Viking Lander surface views, 32 vintage gelatin silver prints, of which twenty are 12.8 x 28cm (5 x 11 in.), five 19 x 24cm (7 ½ x 9 ½ in.) and seven 12.8 x 13cm (5 x 5 ¼ in.), all with frequency, algorithm and histogram calibration data panels, image sizes vary, versos blank as issued, 1977-1980 (32)

⁂ A rare group of early prints from the unrivalled photographic and computer resources of the Image Processing Laboratory at JPL. Sent from the twin panoramic cameras mounted on each of the two Viking Landers to the terrestrial tracking stations of the Deep Space Network, images were decoded by the Telemetry Processor Program and hard-copy prints produced by the real time first-order processing program known as Fovlip. These examples, with provenance to a former JPL staff member, were intended for internal scientific analysis and include some of the first detailed views of the Martian surface.
