Abstract Ball Aerospace has been performing integration and acceptance of its flight Stirling-cycle mechanical cryocooler for the High Resolution Dynamic Limb Sounder (HIRDLS), an instrument slated to fly on the Earth Observing System Chemistry Platform. The HIRDLS cooler subsystem (CSS), developed under subcontract for the NASA Goddard Space Flight Center Earth Observing System Program, consists of a sophisticated and highly reliable, single-stage, fixed regenerator, Stirling cryocooler and its drive electronics, interfacing hardware, cryocooler support bracketry, and the cryocooler radiator. The HIRDLS CSS provides 60 K cooling to the vibration isolated detector subsystem while the cooler is supported in a heat rejecting radiator attached firmly to the instrument structure. The electronics with embedded software are mounted on another panel of the instrument structure. The engineering model was delivered in July 1999, and the flight model is scheduled for delivery in July 2000.
