FOREWORD
The Apol lo Lunar Surface Experiment Package Archi ve Tape
Description Document is intended for us e in conjunction with
the Apollo Scient i fic Experiment s Handbook, NASA TM X-58l 3l
dated August 1974. These documents will aid Principal Investi
gat or s (PI 's) , other than those ori ginally assigned, in their
retrieval of experiment data from archived digital ALSEP
tapes: The Apollo Sci ent i f i c Experiments Dat a Handbook pre
sents a brief description of each of the Apol l o scientific
experiments together with the operational history, the data
contents and formats, and the avai~ability of digitally proc
essed tapes provided by the PI 's . The Apollo Lunar Surface
Experiment Package Archi ve Tape Descr i ption Document provides
the information needed to develop sof tware for retrieving
di gital exper iment data from any of the five Apol l o Lunar
Sur face Exper iment Package (ALSEP) 24-hour, time-edited save
tapes . These tapes are gene rated at JSC and subsequently
archived at the Nat ional Records Center, Suitland, .Maryland.
