Abstract

Utah State University/Space Dynamics Laboratory, teaming with NASA Langley, has built, tested, integrated, and launched the SABER instrument. This instrument is orbiting the Earth on board the TIMED satellite, which resides in a 600 km circular orbit. SABER utilizes a pulse tube cryocooler to cool the focal plane assembly to 75K and passive radiators to cool the remaining components of the instrument. This paper will document the thermal design and modeling of the SABER instrument and compare the modeling results with acceptance testing and on orbit performance data. Preliminary on orbit data indicates that SABER is performing as modeled and is meeting all science objectives.
