The optical properties, chemical composition, and structure of materials on the surfaces of airless bodies in the Solar System, such as the Moon and asteroids, are altered by cosmic-ray irradiation, including solar wind and galactic cosmic rays, as well as by micrometeorite bombardment. These processes are collectively known as space weathering, which is why the differences exist between telescopic observations of asteroids and meteorites in reflectance and spectral properties. The regolith of the surface experienced shattering, abrasion, and compression for a long-lived history of the bodies. Sometimes, dust particles lofted by impact or electrostatic force cover the surface on top of the regolith. The situation gets more complicated once volatiles, such as water, are involved. These complex processes are impossible to reproduce or simulate on Earth comprehensively, even with the samples from the Moon and asteroids. A new approach, such as polarimetry using PolCam, onboarded Danuri, and GrainCams for NASA CLPS, the Commercial Lunar Payload Service program, will contribute to understanding the regolith's surface structure and properties. In this opportunity, I will also introduce the scientitic motivations of LUSEM, LSMAG, and LVRAD instruments for NASA CLPS and discuss future lunar exploration plan updates.
