Apollo 12

Apollo 12 was NASA's second crewed lunar landing mission, flown by Pete Conrad, Richard Gordon, and Alan Bean from November 14 to 24, 1969. Lightning strikes during ascent disrupted spacecraft electrical indications, but the crew and controllers restored operations and verified that the mission could continue. Gordon remained in lunar orbit aboard Yankee Clipper while Conrad and Bean landed Intrepid in the Ocean of Storms. The precision landing placed them within walking distance of Surveyor 3, the robotic spacecraft that had arrived in 1967. During two surface excursions, they collected geological samples, deployed an Apollo Lunar Surface Experiments Package, and removed Surveyor components for study of prolonged exposure to the lunar environment. A damaged television camera limited live surface coverage but did not end the scientific programme. The astronauts rejoined Gordon and returned safely to the Pacific. Apollo 12 demonstrated targeted landing and more extensive fieldwork, advancing from Apollo 11's first landing toward repeated scientific exploration.
