Lunar Environment Monitoring Station (LEMS)
ETD Role: The LEMS project team at Goddard has built an engineering unit of the station to demonstrate its autonomous self-sustaining operation in the lunar surface conditions. The LEMS unit was subjected to vibration tests to simulate the mechanical stresses of launch and Moon landing. During testing the LEMS prototype was subjected to the ultra-high vacuum and harsh thermal conditions that mimic the surface of the Moon to demonstrate that the station can sustain itself and operate unassisted for long durations.
The Lunar Environment Monitoring Station (LEMS) is one of the first three payloads to be a part of Artemis III, NASA’s mission that will send astronauts to explore the region near the lunar South Pole. Artemis III, currently planned to launch in 2026, will be the first time humans will return to the Moon’s surface since the historic Apollo program in 1969-1972.
The Lunar Environment Monitoring Station (LEMS) is a compact, autonomous seismometer suite designed to carry out continuous, long-term monitoring of the seismic environment, namely ground motion from moonquakes to meteorite impacts in the lunar south polar region. The instrument will characterize the regional structure of the Moon’s crust and mantle, which will add valuable information to lunar formation and evolution models.
LEMS can operate autonomously and sustainably for years at the Moon to collect geophysical measurements continuously during lunar days and nights. LEMS is intended to operate on the lunar surface from three months up to two years and may become a key station in a future global lunar geophysical network…
