Lunar Surface Magnetometer

NSSDC ID: 1972-031C-03
Mission Name: Apollo 16 Lunar Module /ALSEP
Principal Investigator: Dr. Palmer Dyal


This experiment consisted of a triaxial fluxgate magnetometer and was part of a three-station network (Apollo 12,15,16) intended to yield information on the internal electromagnetic characteristics of the moon. Flippable sensors were located 75 cm above the lunar surface at the ends of three orthogonal 100-cm booms. Sensor orientation was initially determined by the astronauts' using a bubble level and a shadowgraph, and has been subsequently monitored (with an accuracy of 0.2 degrees) by gravity-level sensors. Each sensor could be operated in the ranges from minus to plus 50, 100, or 200 gammas, with a 0.1-gamma resolution. Frequency response was from 0 to 3 Hz.
