- China is planning to launch its own 'artificial moon' by 2020 to replace streetlamps and lower electricity costs in urban areas.
- For this China has developed “illumination satellites” that will shine in tandem with the real moon, but are eight times brighter
- By reflecting light from the sun, the satellites could replace streetlamps in urban areas, which can illuminate an area of 50 sq. km.
Background
- China is not the first country to try beaming sunlight back to Earth.
- In the 1990s, Russian scientists reportedly used giant mirrors to reflect light from space in an experimental project called Znamya or Banner.
