The CubeSat to study Solar Particles (CuSP) is a 6U cubesat mission designed to study radiation from the star, solar winds, and solar events. CuSP carries three scientific instruments to study this space wather. The Suprathermal Ion Spectrograph (SIS) detects low-energy solar energetic particles at 3-70 keV/q; the Miniaturized Electron and pRoton Telescope (MERIT) counts high-energy solar particles at 2-150 MeV/q; and the Vector Helium Magnetometer (VHM) monitors the strength and direction of magnetic fields.

CuSP launched as a secondary payload on the Artemis 1 mission on 16 November 2022. It was deployed successfully, but contact was lost after about 1 hour.
