China is preparing to launch three artificial satellites into space in 2022, the state-owned Science and Technology Daily reported. The project will be completed by 2020.

The artificial or artificial moon is a satellite carrying a huge spatial mirror that can reflect sunlight on Earth.
Verification of launch, orbit injection, deployment, illumination, tuning and control of the artificial moon will be completed by 2020, the daily said quoting Wu Chunfeng, director of the Tianfu New District Scientific Research Institute in Chengdu, Sichuan Province (southwestern China).
Lampposts, another state-run media, Xinhua said Wu.
These artificial moons will be launched in 2022, the statement said. "From here, the three huge mirrors will divide the orbital plane 360 degrees, lightening an area for 24 hours in a row," said Wu.
The light Reflected solar can cover an area of 3,600 km at 6,400 km. The intensity of the lighting should be eight times the moonlight, he said.
The moon revolves around the Earth at about 380,000 km from the Earth, while the artificial moon should be placed in an orbit less than 500 km from Earth, reported the China Daily, a government newspaper.
Worrying that the artificial moonlight will interrupt the normal day-night cycle of animals and plants, Wu said that the intensity of light and the duration of illumination could be adjusted as well as the accuracy of lighting can be controlled in tens of meters. When an artificial moon is in orbit, people can only see a bright star in the sky.
The artificial moon is particularly useful in civilian areas.
"Using the artificial moon to illuminate an area of 50 square kilometers can save 1.2 billion yuan of electrical charge," Wu said. "It can also illuminate blackout areas in the event of natural disasters such as than earthquakes. "
The United States and Russia have explored the artificial moon, hoping that it will facilitate nocturnal activities.
In the 1990s, Russia an experiment called Banner, testing the idea of using a mirror to reflect sunlight to the Earth. The mirror failed to deploy in the space and the experiment was stopped.
"China, Russia, the United States, Japan and the EU are all striving to make technological breakthroughs in the field of the use of space energy "said Wu.
