A recent news report suggests that China has an ambitious plan:
to send three artificial moons into space in the next four years
that would be
bright enough to replace the streetlights in the south-western city of Chengdu by 2020
The source of the report is "state media People's Daily" (but also the state-run Xinhua media agency) and quotes are attributed to "Wu Chunfeng, chairman of Chengdu Aerospace Science and Technology Microelectronics System Research Institute Corporation".
This sounds like a hoax or legend to me.
Attempts to Google that company just lead to variants of this report, although the vaguaries of translations mean this doesn't mean the company doesn't exist on the web.
Putting aside whether the plans are technically feasible and/or funded, is there are private or public effort to launch satellites that illuminate cities in China?
