According to the National People’s Daily, the artificial moon – which is basically a glowing satellite – will launch in 2020.



The Chinese city of Chengdu wants to exchange street lighting with an “artificial moon”.

According to the People’s Daily, the artificial moon &#821

1; which is basically a glowing satellite – will be launched in 2020, with the permission of Chengdu Aerospace Science and Technology Microelectronics System Research Institute.

The artificial moon will be eight times lighter than the real moon, People’s Daily says, and will light a range between 10 and 80 kilometers in diameter, although the range can be controlled within a few dozen meters.

The moon paves the city at an altitude of 500 kilometers and will be one of three artificial moons sent to space in the next four years. According to ABC, the moon can save about 1.2 billion yuan (240 million dollars) in electricity costs each year. And unlike conventional streetlights, it can also be used to light up areas that have no power or have suffered natural disasters such as earthquakes.

The idea came from a French artist who suggested that a “necklace of mirrors over the earth … can reflect the sunshine through Paris streets all year round,” People’s Daily said.

This is not the first reflective satellite as Russian scientists tried it in 1993; a second time in 1999, “preemptive concerns gave light pollution that disturbed nightly animals and astronomical observation.” The Guardian reports.

Kang Weimin, chief for the Optics School, the Aerospace School, Harbin Institute of Technology, tells People Daily that “the satellite light resembles a twilight-like glow, so it should not affect animal routines.”
