The CE-1 satellite was successfully launched on October 24, 2007, and was guided to crash-land on the Moon on March 1, 2009. The FPGA of the CCD stereo camera operated more than 1 year without faults, exceeding the expected life span by about 4 months. The first lunar image from CE-1 was obtained on November 20 and November 21, 2007, and was released on November 26, 2007 (Figure 14). A three-dimensional image was acquired by processing at the same time and released on November 26, 2007 (Figure 15). The raw data obtained by the CCD stereo camera included 508 orbit images between the latitudes of 70°N and 70°S and 589 polar orbit images. Many scientific results have been obtained by analyzing these data [26], especially the ¿global lunar image from the first Chinese lunar exploration mission¿ in [27]. The results of the onboard flight validate that the FPGA design of the CCD stereo camera is reasonable and reliable and has achieved the mission requirements.
