The Orion spacecraft is a deep space, crewed vehicle designed to support NASA’s Artemis exploration campaign. NASA successfully completed an uncrewed test flight of the Orion spacecraft during the 26-day Artemis I mission in November and December 2022. At numerous points during the mission, a small but measurable amount of power was generated by a solar array wing (SAW) while pointed away from the sun. This presentation discusses an analysis of in-flight telemetry data to characterize this condition. Various potential sources of reflected light were examined, with self-reflection off the spacecraft itself having the largest impact. Different array and attitude configurations were studied to characterize the array response to this spacecraft albedo.
