original title: Chengdu "artificial moon" launched in 2020! Achieve 24-hour lighting

it is reported that recently, Chengdu Aerospace Science and industry Microelectronics System Research Institute Co., Ltd. disclosed that the "artificial moon" project conceived by the company is under demonstration, and the first "artificial moon" will be launched in 2020. This "man-made moon" will provide continuous night lighting for Chengdu at night, which is expected to completely replace street lights and save 1.2 billion yuan in annual electricity expenditure

according to the disclosure of Chengdu Aerospace Science and industry Microelectronics System Research Institute Co., Ltd., the first "man-made moon" will be launched in 2020. In order to achieve 24-hour lighting, it is expected to complete the launch of three "man-made moons" in 2022, equally divided into 360 ° orbital planes and operated alternately

the so-called "artificial moon" is an artificial lighting satellite with a large space mirror. It is reported that the "artificial moon" can use sunlight to provide illumination for the city, and its maximum illumination intensity can reach 8 times of the moonlight. The "artificial moon" is expected to be deployed in a low earth orbit within 500 kilometers

in fact, the idea of "artificial moon" has a long history. It has appeared in science fiction for a long time. Russia was the first to implement this idea. As Russia is located in the high latitude region, the illumination time is relatively short, which means that the electricity expenditure is much higher than that in other regions. Therefore, in 1999, they tried the "artificial moon" and tried to use a special reflector to reflect sunlight from space to shine on the ground. However, in the end, due to the failure of the space mirror expansion, the plan was stranded

according to wuchunfeng, director of Chengdu Tianfu New Area System Science Research Association, the reason for Russia's failure lies in the large-scale space reflector. At present, our core technology and engineering basic materials have a high degree of maturity, and we have the development conditions to carry out the system demonstration and verification stage

for people, every kind of experimental machine now has its own structural characteristics. It is not a good thing to have a city with excellent performance all night. Too much light at night will increase the professional dispersion probability of human suffering from obesity, depression, sleep disorders and other diseases. The alternation of day and night is an objective natural law. Lighting cannot be increased indefinitely because human activities need light. In addition, at night on rainy days, the "artificial moon" is far from being able to pass through the thick clouds to provide enough light. In other words, the "artificial moon" depends on the light of the sky in the final analysis

renxiaodong, director of the star Working Committee of China Biodiversity Conservation and green development foundation, believes that "the artificial moon" may bring serious light pollution, and the project needs to be cautious. "
