[PPS08-02] New Results from Restored Apollo Magnetic Field Records
Keywords:Moon, Apollo magnetic field experiments, plasma waves at the Moon, magnetic sounding of lunar interior, solar wind interaction with the Moon
A recent effort has restored all the Apollo magnetic field records from the archaic data format originally archived. The restored LSM data have revealed many narrowband ion cyclotron waves in the Earth’s magnetotail that were not investigated during Apollo years. The restored data also allow re-analyses for the Moon-solar wind interaction and magnetic sounding of the lunar interior. We find that the observed transfer function responses in both tangential and radial components on the lunar surface are consistent with theoretical expectations at least for frequencies greater than 10-4 Hz. The comparison between SBM and LSM data indicates that, when the Moon is in the solar wind, the surface magnetic field is slightly enhanced on the sunward side. This paper summarizes the recent findings from the restored Apollo magnetic field data and discusses the unexplored topics for future magnetic field measurements on the lunar surface.
