Power Supply

Power Supply was provided by 9480 silicon solar cells, which occupied almost the entire outer surface of the satellite cylinder. This gave it an output of around 60 W. In order to increase the longevity of the solar cells, they were constructed to last longer than the initial lifetime of the mission. A backup battery was also installed to allow for the satellite to operate, while in the Earth's shadow.
