Timing problem with the Lunar Module impact data as recorded by the LSPE and corrected near-surface structure at the Apollo 17 landing site

摘要

It has recently been discovered that the Apollo 17 Lunar Module (LM) impact data from the Lunar Seismic Profiling Experiment (LSPE) had a serious timing problem. Correcting this problem changes the lunar near-surface seismic velocity structure significantly from the structural models reported in the earlier publications, extending a low-velocity (Vp～1 km/s) layer down to a 3 km depth or deeper.
