Science Experiments - Lunar Surface Gravimeter

Lunar Surface Gravimeter

This experiment was part of the ALSEP package on Apollo 17 and was intended to make highly accurate measurements of how the Moon's gravity varied with time. The primary purpose of this experiment was to search for gravity waves, which are predicted by Einstein's theory of relativity. In addition, these measurements would have contributed to studies of lunar seismology and of tidal deformation of the Moon. Unfortunately, the experiment failed due to a manufacturing error.
