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). ",
