LADEE determined the composition of the lunar atmosphere and
investigate the processes that control its distribution and variability,
including sources, sinks, and surface interactions. LADEE also addressed
the longstanding mystery of whether dust is present in the lunar exosphere,
and reveal the processes that contribute to its sources and variability.
