The NASA Surveyor program is a series of seven lunar landers intended to study the surface of the Moon up close from 1966 to 1968. Their findings would later prove to be critical to the eventual success of the Apollo program of landing a man on the moon before the decade of the 60s is out. Five landers successfully touched down and relayed data back to Earth, of which one of them (Surveyor 3), is the only spacecraft ever visited by humans (Apollo 12) on an extraterrestrial surface to this day.
