Surveyor 3
NASA’s Surveyor 3 lander is the first and only human-built probe to be visited by humans on the surface of another celestial body. From 1966 to 1968, the space agency sent Surveyor 3, along with a batch of similar landers, to the Moon in advance of the Apollo missions. Five of the seven Surveyors sent to the Moon performed successful soft landings, but only Surveyor 3 was re-visited, a feat accomplished during Apollo 12. I’d very much like to see us reunited with the lander for a second time.
