19 November 1969: The Apollo 12 lunar lander, LM-6, named Intrepid by the flight crew, landed at Oceanus Procellarum, The Moon, at 06:54:35 UTC. The lunar module touched down within approximately 600 feet (183 meters) of the intended landing site, the lunar probe Surveyor 3, which had landed there 20 April 1967. The landing site is named Statio Cognitum.
Mission Commander, Charles (“Pete”) Conrad, Jr., began the first lunar EVA at 11:32:35 UTC and set foot on the surface at 11:44:22 UTC. Approximately one-half hour later, at 12:13;50 UTC, Lunar Module Pilot Alan L. Bean, Jr., also stepped out onto The Moon.
21 July 1969: After spending a total of 21 hours, 36 minutes, 21 seconds on the surface of The Moon, astronauts Neil Armstrong and Buzz Aldrin fired the rocket engine of the Lunar Module’s Ascent Stage. The liftoff was at 17:54 UTC.
Three hours and forty minutes later, the Eagle ascent stage docked with Columbia, the Command/Service Module, in lunar orbit.
10:56:15 p.m. Eastern Daylight Time, Sunday, 20 July 1969 (02:56:15, 21 July 1969 UTC): 109 hours, 24 minutes, 15 seconds after the Apollo 11/Saturn V was launched from Cape Canaveral, Florida, NASA Astronaut Neil Alden Armstrong set foot on the surface of the Moon.
“That’s one small step for a man. . . one giant leap for mankind.”
This was the most significant event in the history of mankind.
