I can’t help but think this comes under the ‘just because we can, doesn’t mean we should’ heading.
Chinese city to replace street lights with orbiting artificial moon by 2020
Within two years, the city of Chengdu aims to swap out its ground-based street lighting with the soft glow of an artificial moon, casting light across 50 square miles of the urban landscape. […]
Reflective panels on board the machine will pick up and redirect the sun’s rays. The satellite will actually glow multiple times brighter than the moon itself, creating a dusk-like atmosphere on demand. The precise illumination can be varied in different sections of the city as well.
I’m sure it’s very technically impressive and will put Chengdu on the map, but…
A Chinese company has plans for an artificial moon to replace streetlights
Meanwhile, other groups are trying to make the world dark again. A 2016 study showed that more than 80% of the world, and 99% of people in the US and Europe, live in “light-polluted” areas, where the sky’s natural glow has been altered by artificial light from buildings and street lamps. Entire cities, like Flagstaff, Arizona and Ketchum, Idaho, are actively working to reduce light emissions at night. Both are certified “dark sky communities” by a group called the International Dark Sky Association, which offers dark sky designations to towns, parks, reserves, sanctuaries, and other places actively working towards a “more natural night sky.”
I remember first reading about dark sky initiatives when we went to the Kielder Observatory, within the Northumberland Dark Sky Park. This fake moon does seem to be a move in the wrong direction.
