Mariner 9 power subsystem design and flight performance

Technical Report ·
OSTI ID:7212633
The design and flight performance of the Mariner Mars 1971 power subsystem are presented. Mariner 9 was the first spacecraft to orbit another planet, and some of the power management techniques employed to support an orbital mission far from earth with marginal sunlight for its photovoltaic-battery power source are described. The performance of its nickel--cadmium battery during repetitive sun occultation phases of the mission and the results of unique tests in flight to assess the performance capability of its solar array are reported.
