We have evaluated the long-term degradation level of the Charge-Coupled Devices (CCDs) by using CCD image data in the cruising phase of Hayabusa (MUSES-C: Asteroid Sample-return Spacecraft) spacecraft. Although the basic design of the X-Ray Spectrometer (XRS) will remain unchanged for the next asteroid mission Hayabusa-2, it is necessary to optimize the data processing method in consideration of the problem clarified in the former mission. For the Hayabusa-2 mission, we evaluated how the hot pixels had worsen the energy resolution in Hayabusa XRS. Then we introduced and examined a new data processing method 'address mask' to suppress the noise originated from the hot pixels that cause other noises as well.
