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 ...
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 ...
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.
This surface is extended through the continents (such as might be approximated with very narrow hypothetical canals). According to Carl Friedrich Gauss, who first described it, it is the "mathematical figure of the Earth", a smooth but irregular surface whose shape results from the uneven distribution of mass within and on the surface of Earth.

Gravity is computed on the ellipsoid surface using the International Gravity Formula. For studies of subsurface structure, the free-air anomaly is further adjusted by a correction for the mass below the measurement point and above the reference of mean sea level or a local datum elevation. [3] This defines the Bouguer anomaly.
