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).
