The placing of the first seismometer on the Moon by the Apollo 11 astronauts in 1969 started the field of planetary seismology. In the following years five other seismic stations were established on the Moon. The seismic network was operated continuously until all of the ALSEP stations were turned off on 1 October 1977. The Viking missions placed two three‐component seismometers on Mars in 1976.
