The LIDAR In-Space Technology Experiment (LITE) will employ LIDAR techniques to study the atmosphere from space. The LITE instrument will be flown in the Space Shuttle Payload Bay with an earth directed orientation. The experiment thermal control incorporates both active and passive techniques. The Laser Transmitter Module (LTM) and the System Electronics will be actively cooled through the shuttle pallet coolant loop. The Receiver System and Experiment Platform will be passively controlled through the use of insulation and component surface properties. This paper explains the thermal control techniques used and the analysis results, with primary focus on the Receiver System.
