FAQs about Analysis of the causes of electric shock in solar container communication stations

How does ionospheric space weather affect ISS charging?

The status of the ionospheric space weather, in particular solar activity/storms affects the density, in particular local density that can increase charging and currents. Motional EMF affects ISS charging because of the size of the ISS vehicle, in particular the length of the truss.

What if EV crew is exposed to ISS shock?

In the case of EV crew hazardous exposure to shock due to negative potential, the crewmember must be at a location on the ISS truss with a negative floating potential, and the EMU must make electrical contact with ISS (either directly or indirectly). As stated earlier, crew electrical contact with the EMU interior is assumed.

How do solar arrays affect the photovoltaic network?

Solar arrays are the spacecraft component that expose the largest surface to the orbit environment. Previous work has shown that effects of micrometeoroid and space debris impacts on the photovoltaic network are effectively mitigated through common measures of redundancy and discharge prevention.

What factors affect spacecraft charging in magentospheric and cis-lunar environments?
