The EPS accurately measures the number of particles over a broad energy range, including protons, electrons, and alpha particles. The magnetometer sensors can operate independently and simultaneously to measure the magnitude and direction of the Earth's geomagnetic field, detect variations in the magnetic field near the spacecraft, provide alerts of solar wind shocks or sudden impulses that impact the magnetosphere, and assess the level of geomagnetic activity. The second magnetometer sensor serves as a backup. The XRS is an x-ray telescope that observes and measures solar x-ray emissions in two ranges: one from 0.05 to 0.3 nanometers (nm) and the second from 0.1 to 0.8 nm. In real-time, it measures the intensity and duration of solar flares
