350 kg track inclination: ~64? Orbital period: ~ 127 The Chang 'e project in Chang Min is a lunar exploration project in China.
It just went online at 6 o'clock today! Image reference:. Yimg/I/icon/ 16/3 Chang 'e project was the first moon landing project initiated in China, and was officially launched on March 1 2003. First, launch a satellite around the moon, then launch an unmanned detection device to detect the soft landing of the moon, and finally send robots to the moon to set up observation points and take samples back to Earth. The whole plan will last for 20 years. The project trilogy Chang 'e project can be divided into three parts: lunar exploration, landing on the moon and stationing in the moon. It can also be divided into three parts, namely, winding, setting and returning. Its main purposes are "obtaining three-dimensional images of the lunar surface", "analyzing the distribution characteristics of useful elements and material types on the lunar surface", "detecting lunar soil characteristics" and "detecting the space environment of the earth and the moon". [Editor] Landing on the moon refers to manned landing on the moon, with the purpose of conducting various experiments to prepare for the future "landing on the moon" project. [Editor] To enter the moon, it is necessary to establish a lunar base for astronauts to stay on the moon for a long time. [Editor's note] The mission plan is to launch the first lunar exploration satellite Chang 'e-1 at 6: 05pm on October 24th, 2007/KLOC-0. 20 12 (expected)-launch the lunar soft landing device, and carry the "lunar rover" for the first lunar soft landing and automatic patrol survey. 20 17 (expected)-launch the lunar soft landing device, automatically sample the lunar samples for the first time and return them to the earth safely, and analyze the samples on the earth [editor] refer to the external link of China Aerospace shenzhou spaceship [editor] to explore the moon-China Net Chang 'e Project is a small work related to aviation, aerospace or aerospace.

Chang 'e is the first lunar exploration program in China. The rocket was launched at 1 phase (1016: 05 on October 24th). The rocket carries a lunar exploration satellite, which will give the lunar racket 1 3D photos, and the rest should have 3-5 stages.

In order to achieve the highest accuracy of astrometry, China researchers proposed to build an observatory on the moon, and make its accuracy reach the world's leading "micro-angular second level" (that is, one millionth of a second). Yesterday, the 248th Symposium of the International Astronomical Society was held in Shanghai Observatory. Nearly 200 experts from 23 countries and regions discussed "micro-angle second-order astrometry". Academician Ye Shuhua, director of the front desk of Shanghai Observatory, told the reporter that Chinese researchers are studying how to build astronomical observation points on the surface of the moon in the second phase of Chang 'e, laying the foundation for the future lunar observatory. According to reports, due to atmospheric interference, the observation accuracy of ground observatories will be affected, and high-precision observatories can only reach the "milli-angular second level" in general. The so-called milliangular second is an angular unit, representing one thousandth of a second, and one second is equal to 360 degrees. Millimeter-second order means that this telescope will produce an error of one thousandth of a second when observing celestial bodies. Although this is a small error, astronomers are not satisfied. So, they put the telescope on the satellite, and it became a space telescope after launch, thus avoiding the interference of the atmosphere and marching to the "micro-angle second level". Academician Ye Shuhua said that although the space telescope has high precision, its life span is short, usually only a few years, and it will shake and have a "visual blind spot". In order to overcome these shortcomings, researchers put forward the idea of establishing an observatory on the moon. In the second phase of the Chang 'e lunar exploration program, that is, the soft landing stage of the moon, astronomical observation experiments will be conducted, which will be the "outpost" for China astronauts to establish a lunar observatory in the future. If there is a lunar observatory, it is equivalent to setting up a permanent space telescope, and researchers can observe all kinds of celestial bodies as long as they control it remotely on the earth. It is reported that researchers from Shanghai Observatory have cooperated with experts from the European Space Agency to improve the accuracy of astrometry, and consider building a thermostatic chamber to solve the problems such as the large temperature difference between day and night on the moon, thus making the Lunar Observatory a reality as soon as possible.
