How bad will the light pollution be when 42,000 of SpaceX’s Starlink satellites are in operation?

Elon Musk has promised that the albedo, or reflectivity, of each Starlink satellite will have zero per cent impact on

astronomy.

We should not have to experience the light pollution of 42,000 Starlink satellites; it should be stopped before then. The satellites are visible with the naked eye under many circumstances, so the experience would be out of a sciencefiction dystopia; skies would be crawling with hundreds of these satellites at a time like so many white maggots. From a light-pollution perspective, the impacts of Starlink will fall into a few categories. First, the Starlink array interferes with astronomical observation and will degrade the research abilities of both professional and amateur astronomers alike. Secondly, it will degrade the experience of wilderness areas that are supposed to be protected from human interference, including impacts to aesthetics, under US law. A night-sky view with hundreds of visible satellites is fundamentally incompatible with the experience of the backcountry, outback, wilderness or the wide-open ocean. Thirdly, we
