中國3顆'人造月亮'擬2022年升空 亮度可達月光8倍

China's man-made moon conception is expected to be realized in 2022, the Science and Technology Daily reported.

據《科技日報》報道，中國人造月球構想有望在2022年實現。

Man-made moon is a satellite carrying a huge space mirror, which can reflect the sun light to the Earth.

“人造月亮”是指運載着大型空間鏡面的衛星，它能將太陽光反射至地球。

According to research plans, the verification of launch, orbit injection, unfolding, illumination, adjust and control of the man-made moon will be completed by 2020, said Wu Chunfeng, head of Tianfu New District System Science Research Institute in Chengdu, Southwest China's Sichuan province.

我國西南部四川省成都市的天府新區系統科學研究會主任武春風表示，據研究計劃推測，人造月球衛星的發射、軌道的對接、展開和照明、調節和控制的實現將在2020年之前完成。

Three man-made moons will be launched in 2022. "By then, the three huge mirrors will divide the 360-degree orbital plane, realizing illuminating an area for 24 hours continuously," said Wu.

2022年，三個“人造月亮”將發射升空。武春風稱：“屆時，這3面巨大的鏡子將切分360度的軌道平面，3顆人造月亮運行可實現對同一地區24小時不間斷照射。”

The reflected sun light can cover an area of 3,600 sq km to 6,400 sq km, and the illumination intensity is expected to be eight times of the moon light, according to Wu.

武春風透露，反射的太陽光可以覆蓋3600到6400平方公里的範圍，光照強度預計是月光的8倍。

The moon orbits the Earth about 380,000 km from the Earth, while the man-made moon is expected to be put on an orbit within 500 km from the Earth.

月球在離地38萬公里的軌道上運行，而該人造月球預計在離地500公里的軌道上運轉。

Responding to worries whether the man-made moonlight will interrupt the normal day-night cycle of animals and plants, Wu said the light intensity and illumination time can be adjusted and the accuracy of illumination can be controlled within scores of meters. When a man-made moon is orbiting, people can only see a bright star in the sky.

對於人造月光是否會干涉正常的動植物晝夜循環的擔心，武春風表示，人造月亮光照強度和照明時間可以調節，並且照明精度可控制在幾十米之內。當人造月球在軌道上運行時，人們僅能在天空中看到一顆明亮的星星。

Man-made moon is especially useful in civil area. "Using man-made moon to illuminate an area 50 sq km can save 1.2 billion yuan of electric charge," Wu said. "It can also illuminate blackout areas when natural disasters such as earthquake happen."

人造月亮在民用方面格外實用。武春風稱：“用人造月亮給50平方千米提供照明可以節省12億元電費。人造月亮在地震等自然災害發生時，可以用於停電地區的照明。”
