The first sunlight reflecting space mirror has been cleared for launch
摘要
美国联邦通信委员会已批准加州初创公司Reflect Orbital发射首颗空间反射镜原型卫星Eärendil-1。该卫星配备59英尺反射面，旨在夜间将阳光反射至地球特定区域。尽管存在对光学天文学影响的担忧，卫星计划于今年晚些时候进入低地球轨道。若成功，该公司将部署更大规模的卫星星座。
Reflect Orbital has been given the green light to launch its first space mirror that aims to redirect sunlight down to Earth at night. The US Federal Communications Commission (FCC) has authorized the California-based startup to build and operate a single prototype satellite in low-Earth orbit later this year, despite concerns over how the technology could impact optical astronomy.
The satellite, named Eärendil-1 in reference to a Tolkien character, will attempt to redirect sunlight to specific areas on Earth after dark using a 59-foot (18-meter) reflective surface. If successful, Reflect Orbital plans to launch and operate a constellation …
