Abstract
The advanced spaceborne thermal emission and reflection radiometer (ASTER) is an instrument for the mission which was selected by NASA to fly on the EOS-AM1 platform in 1998. The mission instrument consists of a visible and near-infrared radiometer (VNIR), a shortwave infrared radiometer (SWIR) and a thermal infrared radiometer (TIR). Two cryocoolers are included to cool the infrared detectors for SWIR and TIR. The mission life of the EOS-AM1 platform is 5 years, and accordingly, an operation life longer than 5 years is required for ASTER cryocoolers. The design goal of the ASTER cryocooler is the realization of a long operation life of 50,000 hours. A split-Stirling cycle cryocooler with clearance seals and a linear electric motor concept is employed for this purpose, and its development program is now being put into practice as independent subsystems. In response to this program, the cryocooler working group was established, and the cryocooler performance was investigated.
