Researchers from the University of Arizona's Lunar and Planetary Laboratory are contributing to two of the three instruments selected by NASA for deployment on the lunar surface by Artemis III astronauts. These instruments will gather critical data about the lunar environment, interior, and sustainability of human presence, aiding NASA's future missions to Mars.

NASA selected these instruments due to their specific installation needs that require human deployment during moonwalks. The mission is set for a 2026 launch with final decisions on manifesting still pending. The chosen payload teams will join NASA's Artemis III science team.

Artemis III aims to return astronauts to the moon after more than five decades, focusing on exploring its south polar region. This area includes some of the moon's oldest parts and permanently shadowed regions, offering opportunities to study previously unexplored lunar materials.

Dani DellaGiustina, an assistant professor at UArizona, is part of a team developing seismometers for the Lunar Environment Monitoring Station (LEMS). These seismometers are designed to detect both deep and shallow moonquakes. "I am stoked because I have been working for years to develop seismic instruments not just for the moon," DellaGiustina said.

LEMS, led by Mehdi Benna from the University of Maryland, Baltimore County, with NASA Goddard handling construction and operations, is a compact suite aimed at long-term monitoring of ground motion in the lunar south polar region. It seeks to enhance understanding of the moon's crust and mantle structure. According to Angela Marusiak from UArizona, one goal is determining if faults on the moon are active enough to pose risks.

The instrument will also monitor meteor impacts during its operation period ranging from three months up to two years.

Professor Erik Asphaug collaborates on another instrument called Lunar Dielectric Analyzer (LDA), which investigates beneath the moon’s regolith—a meter-deep layer of airless soil—using electric field responses. "As a child of the Apollo era," Asphaug stated his excitement about being involved in this endeavor.

LDA measures porosity and volatile presence like ice within regolith near potential frost activity areas around South Pole regions using radio signal reflections technique as explained by Asphaug: “Different materials propagate radio signals at different speeds.”

Hideaki Miyamoto leads LDA development under Japan Aerospace Exploration Agency support while being affiliated with institutions such as Tokyo University & Adelaide University among others globally
