“…In direct charging, there is no cathodic spot able to create this dense plasma. These results are very similar to those obtained by [4] where no secondary arc was triggered and same current shapes were recorded. V bias is set to the minimum value corresponding to the ESD triggering threshold.…”

Space environment exposure may create cracks on solar panel backside wires. Considering the wiring design of solar array backside, environmental constraints applied on each wire are identical. Thus, the probability of two adjacent wires to have cracks facing each other is very high. This configuration presents a risk of secondary arc occurrence which can lead to a destructive process as arc-tracking. In order to determine in which conditions electrostatic discharges (ESD) can lead to an arc, we have carried out an experimental study on solar panel backside-like samples. We have tested different types of wires presenting artificial mechanical cracks or space simulation aging cracks, set on a solar panel backside coupon. The wires are connected to a secondary arc test setup including a solar array simulator (SAS) set to different current values. As both direct and inverted potential gradient (IPG) charging are theoretically possible on geostationary orbit (GEO) and low earth orbit (LEO), we have carried out, in the JONAS vacuum chamber (ONERA facility), both charging types. Direct charging was achieved with an electron gun and IPG with a plasma source. Results are presented for the two types of charging, different types of wire, and different SAS current values. They show that, in direct charging conditions, ESD propagates along the wires but the plasma density is too weak to provoke an arc. In IPG situation, ESDs are able to trigger different arc types: nonsustain arc (NSA), temporary sustain arc (TSA) and permanent sustain arc (PSA), depending on SAS current values.

“…Other important strategies are to ensure that any potential problems such as floating conductors and dielectrics have either appropriate bleed paths to reduce charge build up or filters to minimize the size and passage of any resultant ESD pulses. Finally, lab testing is sometimes carried out to investigate the susceptibility of hardware to ESD, and the impact should occur [ Likar et al ., ; Wright et al ., ; Hoang et al ., ; Wong et al ., , Likar et al ., ].…”

This paper describes space weather impacts to the satellite infrastructure as perceived by satellite industry stakeholders. The information was gathered through in‐person and remote meetings with both satellite operators and manufacturers. The paper describes current impacts, industry processes for managing and mitigating impacts, costs, and industry needs and requirements. Lastly, we suggest potential improvements and solutions to problem areas based on our observation of the industry processes including (1) improved tools for quick anomaly attribution, (2) training, and (3) coordinated information sharing.
