  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.
