This experiment was carried out in a part of the ALSEP (Apollo Lunar Surface Experiments Package) of Apollo 15 and 17, which started operations on July 31, 1971 and December 12, 1972, respectively. The data of all ALSEP experiments including Heat-Flow Experiments (HFE) had been obtained until September 30, 1977. Langseth et al. (1976) concluded that the lunar surface heat-flow values were 21 mW/sq m at the Apollo 15 landing site and 14 mW/sq m at the Apollo 17 by using the data until December 29, 1974. These values have been widely accepted as appropriate. We confirmed the presence of un-archived data in the acquisition process of HFE data between March 1, 1976 and September 30, 1977. We archived the HFE data (Saito et al., 2006), converted them to physically meaningful values. As a result of preliminary analysis of the data, the observed lunar surface heat flow values are corrected to be about 4 mW/sq m. It indicates that the bulk U abundance is to be 9.5 ppb which is about a half of the Earth's value, much less than previously estimated., 資料番号: AA0063505015}, pages = {57--60}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Re-analysis of Apollo lunar heat-flow value: Re-revised lunar heat-flow value}, year = {2006} }
