DARPA has launched the Lunar Assay via Small Satellite Orbiter (LASSO) program, seeking proposals for a lunar orbiter to test navigation and propulsion technologies in very low orbits (as low as 10 km).

The mission aims to map the lunar surface for water ice, focusing on regions with at least 5% subsurface concentrations.

This effort could improve space situational awareness (SSA) in cislunar space and support NASA missions by identifying potential water reserves, Space News has reported.

DARPA plans to select proposals for a design study, with a goal to develop the LASSO spacecraft for a future mission to the moon.
