Great achievements in China's Chang'e lunar probe to fill the gaps
China news agency, Beijing, July 16 (Reporter Sun Zifa) - National Defense Industry Office 16, issued outside "Chang'e One" scientific research that, through the "Chang'e One" received detection data processing, analysis and research, had made "full moon, the international advanced image map", "precision and highest resolution digital elevation model of the full moon and three-dimensional topographic map the Moon," "important element of the full moon and the local area of content distribution," " Table of microwave radiation on the full moon brightness temperature distribution, "" a unique space in recent months, high-energy particles and solar wind plasma data "such as a large number of research results.
from October 24, 2007 was successfully launched from March 1, 2009 on a successful hit controlled, China's first lunar probe satellite "Chang'e" after a period of 1 year and 4 months in orbiting satellite carrying a payload of 8 units total of raw data about 1.37TB, as of February 2010, was corrected through a variety of data products generated about 4 2.76TB. Chinese Academy of Sciences, the Chinese Lunar Exploration Moon Ouyang said chief scientist of Applied Science, through the detection data processing, analysis and research, and has achieved initial results in China to fill the gaps in the field of lunar exploration.
- the full moon, the international advanced image map. "Chang'e I" CCD stereo camera total of 508 tracks within 70 ° north and south latitude and 589 polar orbit image data, for the first time to achieve 100% coverage of the lunar surface. Production of "all the moon image map" in the geometric registration accuracy, data integrity and consistency, so color images are at the international advanced level.
- the highest accuracy and resolution digital elevation model and the full moon, three-dimensional lunar topographic map. Laser altimetry data to produce a resolution of the full moon is about 3 km digital elevation model, accuracy and resolution on the international advanced level; with three-line array Digital Photogrammetry Methods for Fully three-dimensional digital terrain map moon, covered in the data range, flat position and height accuracy, spatial resolution were better than the existing full moon, the international digital terrain products.
- an important element of the whole moon and the local area content distribution. "Chang'e I" for a total of 1103 gamma-ray spectrometer detecting the data tracks, the ground application system of the gamma-ray data processing, interpretation of the uranium, thorium, potassium and other elements of full moon Category 3 content and distribution, and interpretation out of magnesium, aluminum, silicon, iron, titanium and other elements of the regional content and distribution of data.
- Table of microwave radiation on the full moon brightness temperature distribution. "Chang'e I" for 1690, a total of microwave radiometer data track detection, covering the whole surface of the moon several times, using four frequencies of microwave radiation data, the full moon brightness temperature maps of the lunar soil characteristics, the thickness of lunar soil and lunar soil rare gases, the study has important scientific value.
- a unique space in recent months, high-energy particles and solar wind plasma data. "Chang'e One" to bring high-energy particles and solar wind ion detector to detect lunar orbit space environment, high-energy particle detector in which a total of 1846 rail access to effective detection data, the solar wind ion detector for detecting the data track in 1815. Currently, the preliminary analysis of these data Di and the comparative study of solar radiation and its rich with Earth's magnetic field He planets (the moon) the 认识 special significance, and Youwanghuode more scientific Fa Xian.
Ouyang said, "Chang'e One" scientific research and intellectual property rights in patents, standards and norms in lunar research, Scientific Research Papers, etc. also play a significant role. According to incomplete statistics, in scientific instruments and detection methods, data processing, has applied to a variety of more than 10 patents, is applying for nearly 60. (END)
