Starting in the mid 1960s, he helped analyze the photographs from the Ranger, Lunar Orbiter, and Surveyor lunar missions. In mapping the moon, suitable landing spots were being sought for the unmanned Surveyor 5 spacecraft (1967) and the manned Apollo landings (1969-72). Masursky headed the group that interpreted television transmissions from Martian satellite Mariner 9 (1971), producing maps to plan the landing of unmanned Viking spacecraft on Mars (1976). He analyzed data on the geological origins and evolution of the planets. He collaborated in foreign projects such as the Soviet Venus probes.
