UNCLASSIFIED ii SECURITY CLASSIFICATION _- The material contained herein has been transcribed into a working paper in order to facilitate review by interested MSC elements. This document, or por- - tions thereof, may be declassified subject to the following guidelines: Portions of this document will be classified CONFIDENTIAL, Group 4, to the extent that they: (1) define quantitative performance characteristics of the Apollo Spacecraft, (2) detail critical per- formance characteristics of Apollo crew systems and equipment, (3) provide technical details of sig- nificant launch vehicle malfunctions in actual flight or reveal actual launch trajectory data, (4) reveal medical data on flight crew members which can be considered privileged data, or (5) re- veal other data which can be individually determined to require classification under the authority of the Apollo Program Security Classification Guide, SCG-11, Rev. 1, 1/1/66.

After the multiplexed voice communications and mission elapsed time had been recorded on board the LM on a single track of the tape, the tape cassettes were transferred to the command module (CM) for the return to Earth. The cassettes were forwarded to NASA Manned Space- craft Center, Houston, where mission elapsed time was converted to ground elapsed time for this document. Transcription of these tapes was man- aged by J. L. Gibbons, Test Division, Apollo Spacecraft Program Office, to whom inquiries concerning this document should be referred. The transcript is divided into three columns time, speaker, and text. The time column consists of four two-digit pairs for days, hours, minutes, and seconds (e.g., 04 22 34 14). The speaker column indicates the source of a transmission; the text column contains the verbatim transcript of the communications. The time used by Mission Control Center (MCC) and indicated as ground-elapsed time (GET) in the flight plan was updated to both the spacecraft and MCC computers but was not updated to the telemetry down- link pulse-code-modulated bitstream or other time-recording devices. This GET updating was performed only to correct significant changes in flight-plan time occurring as the result of delayed lift-off, midcourse corrections, or spacecraft burn-time differences (trajectory dispersions). Therefore, the Apollo elapsed time (the true mission-elapsed time) does not always agree with flight-plan and MCC times. Users of this transcript are cautioned to apply the appropriate time-update deltas for the updated periods. Dashes in the time column indicate that the time could not be determined because of the use of the VOX mode. Speakers in the transcript are identified as follows: _. CDR Commander Eugene A. Cernan CMP Command module pilot Ronald E. Evans LMP Lunar module pilot Harrison P. (Jack) Schmitt SC Unidentifiable crewmember MS Multiple speakers CC Capsule communicator (CAP COMM) UNCLASSIFIED vi i:: _ _'_ Z':_ _ '_'_¸'_ In the text, a series of three dots (...) designates those portions of the communications that could not be transcribed because of garbling. One dash (-) indicates a speaker's pause or a self-interruption. Two dashes (- -) indicate an interruption by another speaker or a point at which a recording was abruptly terminated. A series of three asterisks (***) indicates voice clipping caused by use of the voice-actuated (VOX) mode. Words given unusual emphasis by the speaker are underlined. The Apollo 17 mission was flown December 7 to 19, 1972; liFt-off uccurred at 05:33:00.60 G.m.t. (12:33:00.60 a.m., e.s.t.) on December 7. The CM was designated America and the LMwas called Challenger. D_v 5 _ 1-1 LM ACTIVATION 0_ 10 15 15 LMP Okay, Ron, how do you - -- CC We're ready to take it. Go ahead.
