Masters Theses
Near-Earth asteroids (NEAs) are not expected to have H2O [water] ice on their surfaces because a) most accreted dry and therefore never contained H2O, and b) their relatively high surface temperatures should drive rapid H2O ice sublimation. However, OH/H2O has been detected on other anhydrous inner solar system objects, including the Moon and Vesta. Possible sources for OH/H2O in the inner Solar System might include production via solar wind interactions, carbonaceous chondrite or cometary impact delivery, or native OH/H2O molecules bound to phyllosilicates. As these processes are active …
