ALSEP Experiment Example: Charged Particle Lunar Environment Experiment
This experiment is identical to one deployed on the lunar surface as part of the Apollo 14 ALSEP. It was designed to measure the numbers, velocities, and the directions of electrons and protons near the surface of the Moon as well as the ways these measurements change in time. Such data are valuable in the study of solar wind, the magnetosphere of the Earth and low-energy solar cosmic rays. Analysis of the Apollo 14 data revealed important information about all of these phenomena.
