A CubeSat mission dedicated to monitor lunar horizon glow

抄録

Lunar horizon glow (LHG) has been seen as an excessive brightness to be monitored in order to estimate the abundance of the exospheric dust grains near the lunar terminator. Monitoring the LHG could reveal critical information on the dust particles near surface and at low altitudes that is extremely critical for the safety of human and robotic explorers. In this study, a CubeSat mission called Horyu-VI is proposed with a multispectral camera as a payload to detect the light scattering above the lunar horizon. It is planned as a 6U CubeSat mission with a 100 km circular orbit, and the secondary mission is considered as monitoring the space weather. During the main mission, the light-scattering events are planned to be captured with multispectral images in various wavelengths such as UV, visible and NIR. As a result, the observations will help to improve our understanding of dust population near the lunar terminator.
