One year ago, the Energetic Particle Detector (EPD) aboard the European Space Agency’s (ESA’s) Sun observing spacecraft Solar Orbiter (SolO) was launched starting a long-awaited journey. SolO (Figure 1) will provide both in-situ and remote sensing measurements in the inner Heliosphere and EPD will contribute particularly to the latter ones. EPD consists of four sensors that share the s ...[Read More]
