Magnetospheric Electrons and Protons: Low Energy

The GOES-R Space Environment In-Situ Suite (SEISS) will include magnetic energetic ion sensors for both low and high energy levels. The low energy product will give the flux of low energy electrons and protons in the Magnetosphere. The results can be used to determine the degree of spacecraft charging experienced by GOES-R. Spacecraft charging can cause arcing to occur between differentially charged surfaces on a spacecraft or to the surrounding plasma. These discharges can damage or destroy critical hardware.  Numerous satellites have experienced anomalies or failure due to this effect.

The current GOES satellites do not have a product in this energy range, but a product based on LANL satellites with similar capabilities can be found here.
