Featured Speaker: Mehdi Benna, Planetary Scientist with NASA at GSFC will be talking about the Lunar Environment Monitoring Station (LEMS), one of the first three payloads to be a part of Artemis III 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.
