Abstracts This document is an edited record of the conversations between the Apollo 16 astra- nauts and mission control pertaining to the geology of the landing site. It contains all discussions and observations documenting the lunar landscape, its geologic characteristics, the rocks and soils collected, and the lunar surface photographic record along with supplementary remarks essential to the continuity of events during the mission. This transcript is derived from audio tapes and the NASA Technical Air-to-Ground Voice Transcription and includes time of transcription and, photograph and sample numbers. The report also includes a glossary, landing site map, and sample table. 17. Key Words and Document Analysis. 17a.

The Apol lo 16 crew spent 20 .2 hours in surface exp lorat ion and traversed approx imate ly 27 km on the lunar rov ing vehicle. This document is an ed·i ted recor{l of the conversat i ons between astronauts John W. Young and Char les M. Duke on the lunar surface and EVA capcom Anthony W. Eng l and at Mission Contro l in Houston during the descent, l�nd ing, and 71 hour� of lunar stay time. It al�o contafns �and ing site· observations by command modu le pi lot Thomas K. Mattingly as wei I as remarks by al I three astronauts during the transearth phase of the mission. It Is a condensation hopefu lly· of al I the verba l data having geologic significance. All discuss ions and observat ions documenting the lunar landscape, its geologic characteristics, the rocks and so i Is co l lected, and the photographic record are reta ined along with the supp l ementary remarks essential to the cont inuity of events during the mission. We · have de I eted the words of mechan i ca I housekeep ing and eng ineering data wh i I e attempt ing not to I ose the persona l and philosoph ical aspects of the exp loration. The sources of th is voi ce transcript are the comp lete aud io and video tapes recorded during the EVAs and the Technical Air-to-Ground Voice Transcription prepared by NASA. The voice record is listed chrono logical ly with each individua l comment preceded by the day, hour, minute and second in Apol lo Elapsed Time <AETl when the statement was made. Apol lo Elapsed Time is the true mission-e l apsed time after I Htoff from Cape Kennedy at 12:54 p.m. E.S.T. on Apri I 16, 1972. Figure I shows the landing site area that was described, samp led and photographed by the Apol lo 16 crewmen. · ACKNOWLEDGMENTS The assi stance of Apol lo 16.astronaut John W.
