ZCB The Electron Losses and Fields Investigation (ELFIN) mission is a space weather mission using three scientific instruments in a 3U+ CubeSat. Each spacecraft has two Energetic Particle Detectors, one for Electrons (EPD-E) and one for Ions (EPD-I), as well as a Fluxgate Magnetometer deployed at the end of a 75cm stacer boom. These science instruments were developed by UCLA staff at the Institute for Geophysics and Planetary Physics (IGPP) and the Earth, Planetary, and Space Sciences department (EPSS).
