Instrument development for lunar surface characteristics

Korea Astronomy and Space Science Institute (KASI) is developing the wide-angle Polarimetric Camera (PolCam) for Korea Pathfinder Lunar Orbiter (KPLO) and a few number of science instruments for US Commercial Lunar Payload Service (CLPS). While KPLO is scheduled to be launched on mid-2022, PolCam will provide the whole polarization map on the Moon for the first time, which implies the size distribution of lunar regolith due to the evolutionay characteristics such as the maturity and the space weathering properties. One of the Korean instrument for CLPS will measure a tiny-scaled structure of the lunar surface, attributed to low gravity and electrostatic environment. we will present an overview of the other science instruments for KPLO and CLPS, as well.
