Abstract:

Methods used for predicting space vehicle structural and equipment temperatures on orbit are presented. The energy balance between the vehicle, deep space, the sun, and the earth is applied to determine dynamic temperature histories for vehicle equipment. Data received from vehicles on orbit are compared to predictions. Certain anomalies are investigated and their causes determined. Application of flight results to vehicle design and prediction methods is described.
