EQUULEUS, a JAXA 6U cubesat on Artemis 1, successfully flew by the moon and tested a water-based propulsion system that placed the spacecraft on a low-energy trajectory to the Earth–Moon L2 Lagrange point.
MMA HaWK arrays will support five small satellites launching on the first Space Launch System (SLS) launch later in 2021: NASA’s LunaH-Map, Lunar Flashlight, Near Earth Asteroid Scout (NEAScout), BioSentinel, and JAXA’s EQUULEUS.
