Space Shuttle Radiator Panel Actuator Assembly, still sealed, measuring approximately 9.5 x 5.5 x 3.5, bearing a parts tag reading, "Actuator Radiator Panel, Drive, Buyer Control No. MC287–0037–0002…Contract No. NAS 9-14000, Mfg. P/N 15820-2, Serial No. UT103." The unit has two connectors, “J1” and “J2,” and the bottom features two parts labels for the pair of 400-volt motors. Unit is stamped "Eng. Test" and bears multiple 1979 and 1980 date stamps. In fine condition. The radiator actuators were utilized to deploy radiator panels for waste heat rejection into space, primarily from the forward Space Shuttle Payload Bay Doors. Six motor-driven latches secured the radiators until the spacecraft achieved orbit; the actuator was energized to deploy the radiator and subsequently to re-secure each panel prior to Space Shuttle de-orbiting and reentry operations.
