Scientific paper

LEED is an integrated instrument suite to determine the state of the dusty-plasma surface environment for both basic science study and as a hazard alert. The system consists of a dust detector, E-field sensor, plasma electron & ion spectrometer, and an IDPU. While the moon is considered to be static, the lunar dust is in fact very active, capable of percolating to near 100 km altitude, to become (at times) energized, and to adhere to human explorers during EVAs. The dust can infiltrate habitats and pose a well-known hazard via human inhalation of small particles. The LEED science objectives are specifically to understand the lunar dusty near-surface environment and to further the understanding of the lunar dusty exosphere. Each of the LEED instrument components are themselves compact, lightweight, have substantial flight heritage, and thus are very suitable to be combined into a small package that can be deployed in orbit, on a rover, or directly onto the surface.
