As specified, outside the US segment is a farm with eight solar panels.

Each of them generates electricity for its own power supply channel.

According to a specialist at the Houston Mission Control Center, outside the station, the battery discharge-charging unit turned off, which he reported to astronaut Kathleen Rubins.

Power supply to one of the eight power channels in the American segment has been cut by a third. 

In the American module Unity had to turn off the smoke detectors and the computer.

High-speed communication with the Earth and one of the four gyroscopes that maintain the station's orientation in space also do not work.

Earlier, Nathan Eismont, a leading researcher at the Space Research Institute of the Russian Academy of Sciences, commented on the state of the ISS.
