China's artificial moon will be realized in 2022, and its intensity is 8 times that of the moon.

It is reported that the idea of artificial moon in Chengdu Tianfu System Science Research Association is expected to be realized in 2022. The first artificial moon in 2020 will complete the demonstration and launch of the whole system from launch, orbit, and lighting to launch. In 2022, the 3 man-made moon will be launched and launched from Sichuan. The whole system of lighting is demonstrated and verified.

Wu Chunfeng, director of the System Science Research Council of Tianfu New District, said that the "artificial moon" in China is an artificial space illuminating satellite carrying large space mirrors. It is estimated that the maximum intensity of light in the low earth orbit within 500 kilometers will be 8 times that of the moon now. According to the relevant research and development plan, in 2020, the "artificial moon" completed the overall verification work from launch, orbit, deployment, lighting to regulation and control. In 2022, the 3 "artificial moon" will launch one of the three satellite launching bases in China. "At that time, these 3 huge mirrors will be equally divided into 360 degree track plane, 3" Moon "alternate operation can achieve the same area 24 hours of continuous exposure, reflecting the sun can cover the surface of the 3600 to 6400 square kilometers range.

In response to the concerns of netizens, such as biological work and rest, Wu Chun Feng said that the intensity of artificial moon and the length of illumination can be adjusted, and the lighting accuracy can be controlled within tens of meters. Although the artificial moon is 8 times the brightness of the moon, considering the influence of atmospheric motion and other factors, the actual illuminance of the working area is roughly equal to the dusk of summer. At that time, people can feel the "artificial moon" illumination, which is about 1/5 of the illuminance of road lighting. It can achieve "where to hit" and "brightness can be adjusted" without worrying about the problem of "clock disorder".

Especially in the civilian field, the "artificial moon" makes full use of sunlight and complements the street lighting at night to save a lot of electricity consumption of infrastructure. In the winter with short sunshine duration, the artificial moon provides illumination, which can play an appropriate role in bringing dawn ahead and dusk lengthening. "With the provision of radiation to Chengdu's 50 square kilometer area as an example, the annual electricity saving expenditure is about 1 billion 200 million yuan. In the blackout area caused by natural disasters such as earthquakes, we can also use "artificial moon" space lighting to relieve panic, light rescue and convenient placement. Wu Chunfeng said.
