中国2020年要发射“人造月亮”?这是认真的嘛
Chendu in China is planning to launch an ‘artificial moon’ that will light up the skies as far as 50 miles around. The so-called illumination satellite set to deploy over the southwestern city of Chengdu in 2020 is touted to be eight times as bright as the real moon, to cast a ‘dusk-like glow’ over the region. Officials have released few details on the project, but say the idea pulls inspiration from a French artist who envisioned a necklace of mirrors hanging over Earth. It will complement the moon to make Chengu’s night skies brighter when it launches in 2020, potentially serving as a replacement to conventional streetlights. The artificial moon can be controlled to light up an area between 10 and 80 kilometers wide (6 to 50 miles). While it might sound implausible , the experts say the technology has been in the works for years and has now ‘matured’ toward readiness. Whether the plan will ultimately come to fruition, however, remains to be seen. Chengdu’s artificial moon has already been met with criticism from skeptics and concerned citizens who argue that the light will have adverse effects on animals and astronomical observation. But it is said that the light will amount only to a ‘dusk-like glow.’ |
