Abstract
On July 20, 1969, America's Eagle touched down in southwestern Mare Tranquillitatis beginning man's firsthand exploration of the moon. This document is an edited record of the conversations between astronauts Neil Armstrong and Edwin "Buzz" Aldrin, Jr., at Tranquility Base, and Bruce McCandless at Mission Control in Houston during the approximately 22 hours spent on the lunar surface. It includes additional commentary during their return to Earth. It is a condensation hopefully of all the verbal data having geological significance. All discussions and observations documenting the lunar landscape, its geologic characteristics, the rocks and soils collected, and the photographic record are retained along with supplementary remarks essential to the continuity of events during the mission. We have deleted the words of mechanical housekeeping and engineering data, attempting not to lose the personal and philosophical aspects of this intensely human experience. The sources of this verbal transcript are the complete audio tapes recorded during the mission and the Technical Air-to-Ground Voice Transcription published by NASA. The voice record is listed chronologically given in days, hours, minutes, and seconds. These are the Ground Elapsed Times (GET) after launch from Kennedy Space Center which was 9:32 a.m. EDT on July 16, 1969. Figure 1 shows the vicinity of the landing site that was described, sampled, and photographed by the Apollo 11 crewmen.
