  • never heard of that type of nnoon
  • You're overthinking it. It's hardly going to be large or bright enough to cause the sort of disruptions you're envisioning. It's basically going to reflect sunlight in the same way the moon does, but in a more localised location. It will of course be useless on cloudy nights. But the hope is that it will save the city millions a year on street lighting and maintenance.

      Its supposed to be 8 times brighter than the natural moon. I'm hoping everything works out well and that this is a viable way to reduce dependence on fossil fuels.
  • From the data in the article, this is fundamentally misinformed. Geostationary orbit requires altitudes of over 22000 miles. At 300 miles, the satellite's rockets would be firing constantly to keep up with gravity, not to mention that that elevation is still within the Earth's atmosphere, so there would be literally tons of force in air drag with that large of a solar reflector. And since China is not on the equator, it'd burn even more fuel to keep from drifting south. We'd be talking hundred of pounds of fuel per minute just to keep the thing in orbit as described by the article. This would be costly, even if rocket fuel is cheap, you have to keep launching refueling missions to keep the artificial moon burning. And if the nozzles ever clog of fuel line ever plugs up, you'll have a giant fake moon crashing into a Chinese city from 300 km up. Even though I'm pretty sure most of it would probably self-destruct, it'd certainly freak people out. TL;DR - it'll never work.

      So you can't answer the question or after all your rambling you forgot the questions? Hint: The question was not 'Is it possible or feasable?'

      I mean, if it isn't possible, it's assumed that it won't do any of those things: it won't be visible in China, it won't affect circadian rhythms, it won't affect nocturnal animals, and it isn't a good idea. And the the adverse effects will be the money wasted by the Chinese government taking this thing seriously.
