Chinese city Chengdu as part of an effort to replace street lights is planning to launch its own fake moon.It will stay in orbit and complement the light of the real one at night with super-high illumination. For the purpose of illumination the fake moon will be a satellite designed.It will take to the skies like a normal satellite and provide eight times more brightness than the real moon.The artificial moon's illuminationwill cover an area spanning 10 to 80 kilometers, but precise lightning could be controlled within tens of meters. This man made moon would use solar-panel like wings and a reflective coating to redirect sunlight and focus it onto the city. It will be visible in the night sky to people in China and other parts of the world. At a recent mass innovation and entrepreneurship event in the city, the details of the fake moon were revealed by Wu Chunfeng, the Chairman of Chengdu Aerospace Science and Technology Microelectronics System Research Institute Co (Casc), Wu. The work on the fake moon has been on for years, but now, the technology has matured enough for a launch in 2020.The idea of a man-made moon comes from a French artist who imagined a necklace of mirrors above Earth, reflecting sunlight on to the streets of Paris.Though bright light could easily affect human body clocks and confuse nocturnal and day-dwelling animals, but the man-made moon being developed will only produce a dusk-like glow, creating no such problems.
