Lunar Ice Cube is a CubeSat mission to study the distribution of water and organic volatiles on the Moon from lunar orbit. The spacecraft is scheduled to be a ride-on mission on the Artemis 1 launch, currently planned for 2022. The primary scientific objectives of the mission are to: enable broadband spectral determination of composition and distribution of volatiles in regolith on the Moon and analogous bodies as a function of time of day, latitude, regolith age, and composition; provide geological context by way of spectral determination of major minerals, and enable understanding of current dynamics of volatile sources, sinks, and processes, with implications for evolutionary origin of volatiles.
