Will the power issues on the ISS affect the ARISS station?
Greetings all,
The ISS appears to still be up on data. Is there any chance the power issues will cause them to turn off the ARISS radio?
Regards Todd KE0CMD
It looks like they have everything still on full power.
*On Friday afternoon (11:55 am Houston Time), power channel 1B experienced an electrical event that telemetry points to a fault in the power channel’s Sequential Shunt Unit [SSU]. An SSU is responsible for regulating the power voltage levels generated by the solar arrays before it is passed to systems downstream,” NASA’s Dan Hout told SpaceFlight Insider. “A seamless power transfer was performed to recover loads from channel 1B to channel 1A. Currently operating on seven of eight power channels, no impact to station systems or operations. Crew was never in any danger.*

And knowing the redundancy likely built into manned spacecraft systems like the ISS, they could probably run the entire station on as few as three channels.
