Apollo 12, the second manned mission to the surface of the moon, is launched from Cape Canaveral, Florida, with astronauts Charles Conrad, Jr.; Richard F. Gordon, Jr.; and Alan L. Bean aboard. President Richard Nixon viewed the liftoff from Pad A at Cape Canaveral. He was the first president to attend the liftoff of a manned space flight.
Thirty-six seconds after takeoff, lightning struck the ascending Saturn 5 launch rocket, which tripped the circuit breakers in the command module and caused a power failure. Fortunately, the launching rocket continued up normally, and within a few minutes power was restored in the spacecraft.
On November 19, the landing module Intrepid made a precision landing on the northwest rim of the moon's Ocean of Storms. About five hours later, astronauts Conrad and Bean became the third and fourth humans to walk on the surface of the moon. During the next 32 hours, the two astronauts made two lunar walks, where they collected lunar samples and investigated the Surveyor 3 spacecraft, an unmanned U.S. probe that soft-landed on the moon in 1967. On November 24, Apollo 12 successfully returned to Earth, splashing down only three miles from one of its retrieval ships, the USS Hornet.
