NASA’s statistical history lists six landings, twelve moonwalkers and 382 kilograms of returned rock and soil. [1]
Apollo 12 landed about 180 meters from Surveyor 3, which had sat there since 1967. Conrad and Bean cut off its camera and other parts and brought them home. [2][3] LRO later photographed both landers side by side. [4]
The last three missions carried the electric Lunar Roving Vehicle and stayed three days. On Apollo 15 David Scott dropped a hammer and a feather on live TV; they hit the ground together, as Galileo predicted for a vacuum. [5][6][7] Apollo 16 drilled more than two meters into the surface. [8]
