Chendu in China is planning to launch an ‘artificial moon’ that will light up the skies as far as 50 miles around. 中国成都计划发射一颗“人造月亮”，它将照亮周边50英里的天空。 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. 这颗所谓的照明卫星将于2020年部署于成都西南部的上空。据称它的亮度是真正月亮的8倍，可以为整个地区提供“黄昏般的微光”。 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. 官方几乎没有公布关于这个项目的细节，但表示该理念的灵感来自一位法国艺术家，这位艺术家曾想象过为地球戴上一条镜子做成的项链。 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. 这颗卫星于2020年发射，它将作为月亮的补给，使成都的夜空更加明亮，而且可能会替代传统的路灯。 The artificial moon can be controlled to light up an area between 10 and 80 kilometers wide (6 to 50 miles). 这颗人造月亮的照明范围可以控制在10~80公里（6~50英里）。 |
