China is reportedly planning to launch a so-called artificial moon over one of their provinces so as to help with urban illumination at night. It would orbit 500Km above our planet, it would reflect sunlight across an area of 10km to 80km and would be eight times brighter than the real Moon with the ability to control that intensity as well.
It's hoped the light source will replace streetlamps and lower exorbitant electricity costs in the country's rural areas.
Furthermore, the satellites will be expensive and challenging to assemble in orbit and is unlikely to last for longer than ten years, he added. Should this happen, the artificial moons could take turns reflecting sunlight, or could even illuminate the Earth all at once if necessary.
The angles of these wings can then be adjusted to allow the light to focus on a precise location, Asia Times reported.
According to state media People's Daily, China's fake moon will light up the streets of Chengdua at night with "a dusk-like glow" across an area anywhere between 10km to 80km wide - and it should be bright enough to replace streetlights.
Several powerful earthquakes strike off the shore of Canada
A series of three aftershocks measured between magnitude-4.3 and magnitude-4.9 followed the initial three earthquakes as well. The second stronger quake occurred 122 miles southwest of the same town more than half an hour later, at 11:16 pm.
Scientists planned to harness light from mirrors in orbit to brighten up cities in Siberia, again as an alternative to electric street lamps. If the first one is successful, there are plans to launch three more by 2022.
Wu Chunfeng, chairman of the city's Aerospace Science and Technology Microelectronics System Research Institute outlined the plan at a news conference without mentioning the cost.
But that amount of lighting is likely to still affect natural circadian rhythms. "When the satellite is in operation, people will see only a bright star above, and not a giant moon as imagined". The Russians attempted to attach the mirror to the Mir Space Station, but the mirror became tangled in other equipment, and the mirror failed to unfold.
Earlier this year, American space startup and Los Angeles based company Rocket Lab launched its own reflective mini-satellite into space from its launch site in New Zealand. The satellite doesn't really serve a objective other than to orbit the Earth every 90 minutes and reflect sunlight off its soccer-ball like panels.
Artificial light can interfere with many animals' natural cycles, such as sea turtles that hatch on beaches and return to sea by detecting the moon's brightness; migratory birds that rely on moonlight and starlight to navigate; and insects that are drawn to light (artificial lights can heat and burn them), according to the International Dark-Sky Association.
