Chinese city plans to launch 'artificial moon' to replace streetlights

China is planning to launch its own "artificial moon" by 2020 to replace streetlamps and lower electricity costs in urban areas, state media reported on Friday. It could replace some streetlights in Chengdu, which will help conserve energy, but it won't light up the entire night sky.

In addition to Tian Fu New Area Science Society, other universities and institutes, including the Harbin Institute of Technology and China Aerospace Science and Industry Corp, are involved in developing Chengdu's illumination satellites.

According to him, this satellite would produce at least eight times more light than the real moon. The moon would be a satellite with a special coating that would reflect the light of the Sun onto Chengdu during the night.

The world's first artificial moon could be launched by 2020, China Daily reports.

Wu said the light intensity and illumination time can be adjusted and the accuracy of illumination can be controlled within scores of meters.


Chinese City Wants to Replace Streetlights With 'Artificial Moon'

In January, an artificial star was launched into space by American firm Rocket Lab, but the reflective mini-satellite received criticism for its contribution to light pollution, Time reported.

Chinese scientists have embarked on a very ambitious project, whose aim is to revolutionize street lighting, and will forever change the night sky over China.

He indicated that the artificial moon has been undergoing testing for several years now to ensure that they met all requirements.

The southwestern Chinese city of Chengdu intends to launch a fake moon into space in that researchers expect would orbit about 500 kilometres above the earth. If the project is deemed to be successful, China plans to send two more of its artificial moon units in the course of the next four years. On Earth, its presence would appear as a "dusk-like glow" that could light an area with a diameter of close to 50 miles. At present, the only way to create a geosynchronous orbit is to put your satellite above the equator and have it match the rotation of the Earth. In the 1990s, Russian Federation experimented with using an orbital mirror to reflect sunlight on some of its sun-deprived northern cities, according to the New York Times.
