Lunar IceCube is a NASA nanosatellite orbiter mission that was intended to prospect, locate, and estimate amount and composition of water ice deposits on the Moon for future exploitation. It was launched as a secondary payload mission on Artemis 1, the first flight of the Space Launch System (SLS), on 16 November 2022. As of February 2023 it is unknown whether NASA team has contact with satellite or not.

Lunar water is water that is present on the Moon. Diffuse water molecules in low concentrations can persist at the Moon's sunlit surface, as discovered by the SOFIA observatory in 2020. Gradually, water vapor is decomposed by sunlight, leaving hydrogen and oxygen lost to outer space. Scientists have found water ice in the cold, permanently shadowed craters at the Moon's poles. Water molecules are also present in the extremely thin lunar atmosphere.
