dc.description.abstract This ATM summarizes the results of the BxA study conducted to investigate the ALSEP Flight 1 PSE Thermal Anomaly. The purpose of the study was to (1) correlate the Flight 1 PSE sensor lunar performance results, (2) determine the most probable cause of the temperature related anomalies, (3) recommend possible thermal modifications to the Flight 4 PSE (Apollo 14) and subsequent units, (4) resolve thermal problems encountered in the implementation of the modifications, (5) provide thermal performance predictions for Apollo 14 and (6) supply recornrncndations for future efforts to improve the experirnent's performance and capability as a scientific research instrument.
