The advanced spaceborne thermal emission and reflection radiometer (ASTER) was developed by the MInistry of Economy, Trade and Industry (METI) for installation in the EOS-AM1 spacecraft. The ASTER consists of a visible and near-infrared radiometer (VNIR), a short-wave infrared radiometer (SWIR) and a thermal infrared radiometer (TIR). Two cryocoolers are required to cool the infrared detectors for the SWIR and TIR subsystems. Two cryocoolers have been operating in orbit for over 22000 hours. The temperature of each detector was stabilized in the allowable temperature range. Long-term data have been acquired on the cooling performance and power consumption under normal operation for each cryocooler, the following are described; outline of ground test results and performance of the ASTER cryocooler in orbit for over 22000 hours.
