Abstract
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a high-resolution optical sensor system that can observe in a wide region from the visible and near-infrared, the short wavelength infrared to the thermal infrared with 14 spectral bands on board of NASA’s Terra spacecraft for Earth Observing System (EOS) “A mission to planet earth." ASTER achieved 5 years mission success on orbit operation normally which is the specified target after launched on December, 1999. And after through 10 years continuous orbit operation, ASTER has still operating the long life observation of extra success to be 15 years in total on December, 2014. As for ASTER instrument that is composed of 3 radiometers; the Visible and Near Infrared Radiometer (VNIR) with 3 bands, the Short Wavelength Infrared Radiometer (SWIR) with 6 bands, the Thermal Infrared Radiometer (TIR) with 5 bands, overall ASTER long life data taken by 15 years onboard operation has been reviewed from the point of view of the health and safety check by Telemetry (TLM) data trend, the function and performance evaluation by observation data trend, the onboard calibration and verification by periodic Calibration(CAL) data trend. As a result, the radiometric degradation of VNIR and TIR and the temperature rise of SWIR detector were identified as significant challenges. The countermeasure plan towards the end of mission was clarified and also the novel lessons learned was verified.
