Abstract

An existing operational low-earth-orbit radiative cooler is being upgraded for use on the Mars Observer polar-orbiting mission, using the Landsat Thematic Mapper cooler as a basis for upgrading. Significant improvements were achieved in the design of the thermal performance and vibration endurance, and in the mass minimization design. The cooler provides about 18 mW of useful refrigeration power in Mars orbit at its equilibrium operating temperature. The detector operating temperature for the worst-case orbital environment is about 73 K.
