The Lunar Surface Gravimeter (LSG) was a lunar science experiment that was deployed on the surface of the Moon by the astronauts of Apollo 17 on December 12, 1972. The LSG was conceived by its principal investigator Joseph Weber.
The superconducting gravimeter achieves sensitivities of 10 –11 m·s −2 (one nanogal), approximately one trillionth (10 −12) of the Earth surface gravity. In a demonstration of the sensitivity of the superconducting gravimeter, Virtanen (2006), [ 8 ] describes how an instrument at Metsähovi, Finland, detected the gradual increase in ...
The Lunar Traverse Gravimeter was a lunar science experiment, deployed by astronauts on the lunar surface in 1972 as part of Apollo 17.The goal of the experiment was to use relative gravity measurements to infer potential attributes about the geological substrata near the Apollo 17 landing site.
Lunar Surface Gravimeter (LSG) The LSG was designed to make very accurate measurements of lunar gravity and its change over time. It was hoped the data could be used to prove the existence of gravitational waves. Lunar Surface Magnetometer (LSM) The LSM was designed to measure the Lunar magnetic field. The data could be used to determine ...
Richard was involved in the Lunar Surface Gravimeter experiment that was proposed by Joseph Weber to NASA in the early sixties to look for possible excitations of the Moon normal modes and resulting motion of its surface due to gravitational waves. As a co-investigator, Richard worked for a solution to the problem of maintaining the temperature ...

Active Seismic Experiment (ASE) was carried on Apollo 14 and Apollo 16 as part of the Apollo Lunar Surface Experiments Package (ALSEP). ASE used a thumper device and a mortar with explosive charges to explore subsurface lunar structure and elastic properties. The experiment's principal investigator was Robert Kovach of Stanford University.
Gravimeter with variant of Repsold pendulum The large increase in gravity measurement accuracy made possible by Kater's pendulum established gravimetry as a regular part of geodesy . To be useful, it was necessary to find the exact location (latitude and longitude) of the 'station' where a gravity measurement was taken, so pendulum measurements ...
