GOES-R is scheduled to launch soon and put in geostationary orbit over North America for high bandwidth continuous monitoring of Earth, with only 120 minutes per year interruptions caused by stationkeeping. It will simultaneously monitor the sun with several instruments and of course it's solar panel. The GOES-R Website describes the satellite in detail throughout many pages and links, and two images are shown below.
I assume that over the course of each day, the shaft that supports the solar pannels and sun-pointing insturments rotates 360 degrees relative to the body of the spacecraft. How do all of the wires for power from the pannels and signal and control connections for the sun-pointing instruments not get twisted up and break after a few days of continuous rotation?
Watch the video below to get a perspecive of the size.
