Lunar eclipse induces disturbance in the lunar exosphere

Abstract

Given the renewed scientific interest in lunar exploration missions, complete understanding of lunar near surface environment and its exosphere under different conditions is of paramount importance. Lunar exosphere has been extensively studied by ground based observations [18,19,20,21,22,23] and hypothesized by different models[1,2,3,4,5,6,7,8,9,10,11,12,13]. In present work, we have discussed overlooked possible sources behind changes in the lunar exosphere when the Moon passes through the penumbra and umbra of the Earth during a lunar eclipse. The dusty turbulent environment due to planetary shadow is not only confined to lunar studies and exploration, but it can also be extended to all terrestrial airless bodies in the universe with a dusty surface e.g. some planets, planetary satellites, asteroids etc.
