Chinese city ‘plans to launch artificial moon to replace streetlights’<\/span><\/h2>\n

In Chengdu, there is reportedly an ambitious plan afoot for replacing the city\u2019s streetlights: boosting the glow of the real moon with that of a more powerful fake one.<\/p>\n

The south-western Chinese city plans to launch an illumination satellite in 2020. According to an account in the People\u2019s Daily, the artificial moon is \u201cdesigned to complement the moon at night\u201d, though it would be eight times as bright.<\/p>\n

The \u201cdusk-like glow\u201d of the satellite would be able to light an area with a diameter of 10-80km, while the precise illumination range could be controlled within tens of metres \u2013 enabling it to replace streetlights.<\/p>\n

The vision was shared by Wu Chunfeng, the chairman of the private space contractor Chengdu Aerospace Science and Technology Microelectronics System Research Institute Co (Casc), at a national mass innovation and entrepreneurship event held in Chengdu last week.<\/p>\n

Wu reportedly said testing had begun on the satellite years ago and the technology had now evolved enough to allow for launch in 2020. It is not clear whether the plan has the backing of the city of Chengdu or the Chinese government, though Casc is the main contractor for the Chinese space programme<\/p>\n

The People\u2019s Daily report credited the idea to \u201ca French artist, who imagined hanging a necklace made of mirrors above the Earth which could reflect sunshine through the streets of Paris all year round”.<\/p>\n

The likelihood of Chengdu\u2019s fake moon rising remains to be seen. But there are precedents for this moonage daydream rooted in science, though the technology and ambitions differ.<\/p>\n

In 2013 three large computer-controlled mirrors were installed above the Norwegian town of Rjukan to track the movement of the sun and reflect its rays down on the town square. \u201cRjukan \u2013 or at least, a small but vital part of Rjukan \u2013 is no longer stuck where the sun don\u2019t shine,\u201d reported the Guardian at the time.<\/p>\n

Longer ago, in the 1990s, a team of Russian astronomers and engineers succeeded in launching a satellite into space to deflect sunlight back to Earth, briefly illuminating the night-time hemisphere.<\/p>\n

The Znamya experiment was to \u201ctest the feasibility of illuminating points on Earth with light equivalent to that of several full moons\u201d, the New York Times said. \u201cSeveral\u201d proved an overstatement, but the design was shown to be sound.<\/p>\n

A more ambitious attempt, Znamya 2.5, was made in 1999, prompting preemptive concerns about light pollution disrupting nocturnal animals and astronomical observation. A spokesman for the technology ministry in Bonn was less concerned, telling the Guardian, \u201cIt\u2019s a bit early for April Fool jokes but this sounds like one”.<\/p>\n

But Znamya 2.5 misfired on launch and its creators failed to raise funding for another attempt.<\/p>\n

The People\u2019s Daily was quick to reassure those concerned about the fake moon\u2019s impact on night-time wildlife.<\/p>\n

It cited Kang Weimin, director of the Institute of Optics, School of Aerospace, Harbin Institute of Technology, who \u201cexplained that the light of the satellite is similar to a dusk-like glow, so it should not affect animals\u2019 routines\u201d. [Source<\/a>]<\/p>\n
