NASA unmanned space probes launched during the late 1960s and throughout the 1970s produced a variety of 4x5 inch computer-generated negatives from radio-telemetric data of the solar system. In 1986, the curators of 25 Years of Space Photography: Jet Propulsion Laboratory, California Institute of Technology, an exhibition and catalogue from 1985-1986, gave five negatives to a senior project leader at NASA. Subsequently, Blackpoint Editions used these original negatives, scanned as 2400 dpi files, to make the carbon pigment prints donated to the Briscoe Center.
