China Releases First Image of Moon from Chang'e 1 (Forwarded)
China National Space Administration
Beijing, China November 26, 2007 China Releases First Image of Moon from Chang'e 1 China National Space Administration (CNSA) officially releases the first image of the lunar surface that the Chang'e 1 satellite transmitted. This marks a complete success for the first Chinese moon exploration project. The first lunar image is obtained by the CCD stereo camera on the Chang'e 1 satellite. The CCD camera uses a linear array in the pushbroom mode to obtain the image, from an approximately 200 km orbit. Each orbit covers the lunar surface 60 km wide. The image resolution is 120 m. The first lunar image is a composition of images from 19 orbits, spanning 57 - 83 deg E longitude and 54 - 70 deg S latitude. The image covers an area approximately 280 km wide and 460 km long. The 60-km swath to the center right of the mosaic is the image that the CCD camera obtained from the first orbit. As the first domestically researched and developed lunar exploration probe, Chang'e 1 satellite was successfully launched on October 24 from the Xichang Satellite Launch Center using a Changzheng 3A (Long March 3A) rocket. Through eight orbital maneuvers the satellite formally entered the operational orbit on November 7. After adjusting and testing the on-board equipment, the satellite was maneuvered to an attitude of facing the Moon on November 18. On November 20 it began transmission of exploration data, which was processed into the first lunar image and a 3-D image. CNSA officials said that Chang'e 1 would continue to transmit all kinds of exploration data in the next year. After the data is processed, it will be given to scientists to study.
