The Lunar Environment Monitoring Station for Artemis 3 (LEMS-A3) is a compact, autonomous, and self-sustaining seismometer suite designed to carry out continuous (day and night), long-term (two years longevity goal), monitoring of the lunar seismic environment at the South Polar region. LEMS-A3 is a self-powered, self-managed, and self-communicating flight system that has all attributes of a standalone science mission. Once deployed on the surface and activated by the Artemis 3 crew, it requires no support from the Human Landing System or the Artemis 3 crew to operate.
