Apollo 12 Intrepid is a lander mission by NASA on Moon. Landed November 19, 1969. Landing site: Ocean of Storms.

Apollo 12’s Lunar Module Intrepid achieved the first precision landing on the Moon, touching down just 183 meters from the Surveyor 3 probe that had landed 31 months earlier. Astronauts Pete Conrad and Alan Bean conducted two moonwalks, deploying the first Apollo Lunar Surface Experiments Package (ALSEP) and retrieving parts of Surveyor 3 for study on Earth. The mission launched through thunderstorms, with the Saturn V struck by lightning twice during ascent.
