The dataset contains all the Passive Seismic Experiment (PSE) data from the Apollo 11, 12, 14, 15 and 16 sites, and the parts of ‘Passive Listening Mode’ data of LSPE (Lunar Surface Profiling Experiment) and LSG (Lunar Surface Gravimeter) experiment performed at Apollo 17 site. The PSE data from July 21,1969 to Feb. 29, 1976 are copies of PSE tape files on Exabyte tapes, and the PSE data from Mar. 1, 1976 to Sept. 30, 1977 are extracted from the Normal-bit-rate Work Tape files. The archived Passive Listening Mode data of LSPE are digital copies of the High-bit-rate Work Tape files, and the LSG data are extracted from the Normal-bit-rate Work Tape files from Mar. 1, 1976 to Sept. 30, 1977.

Data Coverage

A general description and the operation status of PSE, LSPE and LSG are described in “The Description of Apollo Seismic Experiments”. The characteristics of seismometers used in these experiments are described in “The Apollo Seismometer Responses”. Please see these documents.

Data Acquisition

These data are archived in original Exabyte format. The decoded data are also stored in the relational database system in ASCII format. You can obtain these data in ASCII format from the “Apollo Moonquake” application.

Original Exabyte Tape Files

You can download the raw original Exabyte-format data files (PSE Tape files and Work Tape files).

The start and the end times of the data on each file are listed in “Catalog of Lunar Seismic Data from Apollo Passive Seismic Experiment on 8-mm Video Cassette (Exabyte) Tapes (UTIG Technical Report No.118)” (Nakamura, 1992), or our “Exabyte file list”. On the Exabayte file list, filename, MD5checksum and comparison between the descriptions in Technical Report No.118 and the actual file information are listed. The red-letter words on the file list indicate parameters that are different from those given in the Technical Report.",
