The NASA Apollo missions from 1969 to 1977 provided the first-ever seismic data from a planetary body other than the Earth. Forty years after the acquisition of these lunar seismic data, lunar scientists continue to analyze them and derive new results related to lunar geophysics. However, the users often find the data difficult to obtain and analyze because at present not all data are publicly available and archived with a convenient interface, and also because the format of the archived data is unfamiliar to many seismologists. To alleviate this difficulty, we have developed a retrieval system for the Apollo seismic data that enables the user to obtain the data and metadata necessary to use them properly. To accomplish this, we first collected most of the Apollo lunar seismic data and information required to analyze them. Then, we built a relational database consisting of the decoded lunar seismic data and an application to access the database on the World Wide Web. Using the database and application, one can search and obtain the required lunar seismic data online. This new data retrieval system will allow more people to access the existing lunar seismic data; and we anticipate that future analysis of the archived data will generate significant progress towards better understanding of the Moon and the solar system.
