There are a variety of thermal control devices on DS1. They include heaters as well as devices designed to send waste heat into space. There are also insulators designed to keep heat in and out. All of these devices work together to create a delicate thermal balance for the entire spacecraft. To reduce cost and weight and power, most spacecraft are designed and built with sides intended to point toward the Sun and sides intended for shade. Instruments that must be kept warm or cold will be placed accordingly.
