China to launch artificial 'moon' into orbit to light up city
"China is to launch a fake "moon" into space that it hopes will illuminate one of
the country's biggest cities. Officials in Chengdu, a city of 14 million people in China's southwestern province of Sichuan, announced plans to place a satellite in orbit by 2020 capable of reflecting sunlight onto its streets at night, claiming it will be bright enough to entirely replace street lights. The satellite would use a reflective coating to direct light to illuminate an area on earth of up to 50 square miles, according to Wu Chunfeng, chairman of the city’s Aerospace Science and Technology Microelectronics System Research Institute."

I can't see the stars at night because of the street lights. Only the moon, maybe a bright planet. How much heat will come with the light? |

But nothing like what I could see 50 years ago. |
