Remote detection of widespread indigenous water in lunar pyroclastic deposits
Milliken, Ralph E.; Li, Shuai
Laboratory analyses of lunar samples provide a direct means to identify indigenous volatiles and have been used to argue for the presence of Earth-like water content in the lunar interior. Some volatile elements, however, have been interpreted as evidence for a bulk lunar mantle that is dry. Here we demonstrate that, for a number of lunar pyroclas…
Snow precipitation on Mars driven by cloud-induced night-time convection
Montmessin, Franck; Hinson, David P.; Forget, François +4 more
Although it contains less water vapour than Earth's atmosphere, the Martian atmosphere hosts clouds. These clouds, composed of water-ice particles, influence the global transport of water vapour and the seasonal variations of ice deposits. However, the influence of water-ice clouds on local weather is unclear: it is thought that Martian clouds are…
