Abstract

This paper describes the issues associated with thermal management of the Sounding of the Atmosphere using Broadband Emission Radiometer instrument, proposed by NASA LaRC and the Space Dynamics Laboratory at Utah State University. With the instrument subjected to severe mass and power constraints, the TRW miniature pulse tube cooler has been baselined to maintain the focal plane at less than 75 K over a required lifetime of two years. Cooler and electronics heat is to be rejected through the spacecraft bulkhead at 300 K to radiators at approximately 290 K. The optical cavity is to be maintained at 210 K by a separate radiator. Approaches to ensure that heat loads do not exceed cooler capacity, radiator studies, and interfacing the cooler to the sensor and spacecraft are discussed.
