The Lunar Experiment Support System and Handling (LESSH)

The Lunar Experiment Support System and Handling (LESSH) is contributing to NASA’s plan to deploy science instruments on the moon near a South Pole landing site beginning with the Artemis III mission.

LESSH is a science instrument package that can be deployed by astronauts and re-charged via an Artemis vehicle, enabling extended science operations. Intended to hold and safely transport scientific instruments, the hardware is meant to bridge the gap between large, long duration instruments and small, short, handheld ones. LESSH will provide astronaut-rated battery power, wireless communications, high speed data processing, and thermal management.
