Abstract
This Paper will discuss the design of a triple redundant cryogenically cooled and isolated Focal Plane Assembly (FPA) for the Compact Remote Imaging Spectrometer for Mars (CRISM) instrument. The FPA is required to operate in the temperature range of 90 - 100K. The CRISM FPA isolation system was constructed from a ceramic fiber composite. The FPA was cooled by one of three cryocoolers individually connected to one of three diode heat pipes that were all connected to the FPA. The total heat load imposed by the isolation system was about 250 milliwatts at operating temperature. CRISM is expected to launch in August of 2005.
