EQUULEUS is a JAXA and University of Tokyo 6U deep-space CubeSat launched on November 16, 2022 aboard Artemis I. It demonstrated low-energy Earth-Moon transfer using water-propellant propulsion, completed a planned lunar flyby, and uses the PHOENIX ultraviolet imager to study Earths plasmasphere while supporting lunar-environment observations on its route toward the Earth-Moon L2 region.
