Discussions with Yan Jun:
"Year of the Dragon the first full moon day, the Chinese scientists to the global astronomical scholars and enthusiasts to send a gift - 7 m resolution, obtained by the Chang'e II lunar probe, 100% coverage of the full moon image maps(http://www.agile-news.com/)(Technology News http://www.agile-news.com/).
On the 6th, the National Defense Science and Industry Bureau issued a major scientific and technological achievements of China's lunar exploration program. Just how the Chang'e II received the full month's image of 'bull'? Dialogue Xinhua News Agency reporter the first time, chief scientist of the Chinese lunar exploration engineering science applications National Astronomical Observatories, Chinese Academy of Sciences, Yan Jun, researcher.
Published the highest resolution image map of the full moon
Reporter: China to obtain resolution of 7 m Figure at what level in the international arena?
Yan Jun: 7 m resolution full month map is published in the international highest resolution image map of the full moon, is another major scientific achievements made by China's lunar exploration project, indicating that the level of China's lunar exploration has a new upgrade .
Its spatial resolution, image quality, data consistency and integrity as well as mosaic accuracy is better than similar digital products of the full moon, the international leading level.
17 times to see the Apollo 11 moon ruins Figure resolution of the full month of Chang'e I
Reporter: 7 m resolution how a precision?
Yan Jun: Chang E II load the camera than the Chang'e 1 camera has been a great leap forward. Chang'e One full month's map with a resolution of 120 meters, the Chang'e II 7 m, 17 times. Popular speak, the camera can only identify the Chang'e I is greater than 360 meters pits, stones, and the Chang'e II can be identified in less than 20 meters.
We even see the full month's figure of the Apollo 11 moon landing ruins.
Can help the car a soft landing of the Moon and a manned lunar landing preferred landing area
Reporters: High-resolution full month map for the implementation of the mission to the moon what is the significance?
Yan Jun: high-resolution full month graph has a very important engineering significance. People can be based on a comprehensive, sophisticated, reliable terrain data, it provides for the lander and lunar rover soft landing in China and other countries to be implemented in the future. and manned lunar landing preferred landing area.
Future Chang'e III is expected to landing on the moon Rainbow Bay area, by reducing the satellite height and adjust the camera position, the Chang'e II also received a resolution of better than 1.3 m image, choose a flat placement Chang'e III provides more foundation the data.
The moon the most comprehensive scientific research the most basic data
Reporter: its lunar research value?
Yan Jun: high-resolution image map of the full moon is the most basic data of the lunar science.
High-resolution full month's image of the fine topography map in the front of the moon, on the back of the Antarctic and the Arctic area, showing the lunar mare, month land and all kinds of crater size, distribution, structure and characteristics to explain The temporal and spatial evolution of small bodies hit the moon, is a division of the full moon terrain partition and geomorphic units based on the relative age of each unit of study the lunar surface provides a scientific basis.
At the same time, high-resolution full-moon images graphic translated full-moon ring structure and lineament maps can be used to divide the tectonic evolution of the moon of the lunar tectonic zoning and research.
Therefore, we study the lunar material characteristics, zoning lunar geological structures, content and distribution chart of the painting on the lunar surface material composition (rocks, minerals, elements), the characteristics and causes of the analysis of lunar topography, and explore the lunar origin and evolution of The scientific value or reference.
Chang E II in good condition, may arrange for more to expand the experiment
Reporter: Chang E II, the current situation? Have any plans for the future?
Yan Jun: Currently, Chang'e II from the moon to fly to the Earth-Moon Lagrange L2 point, to carry out the space environment exploration and engineering test now in good condition, as the detector status, may arrange for more to expand the test task.
Example, the detection of charged particles in Earth's far magnetotail, the solar X-ray observation of possible outbreak of the cosmic gamma-ray burst phenomenon, and deepen the understanding of the terrestrial space environment.
Further verify that the 1.5 million km long-distance monitoring and control communications, deep space exploration, a key technology for the follow-up project to accumulate more experience (Xinhua News Agency, Beijing, February 6) - "
