Relay station will eventually let teams on the ground talk to a lunar probe that China plans to launch this year in world-first mission
China is one step closer to being the first country to land on the dark side of the moon.
At 5.28 am on Monday, the Queqiao relay satellite was launched from Sichuan province, according to Chinese nation media. With Queqiao in place, China will be able to send a lunar probe to the side of the moon that never faces the Earth. No space program has ever reached that part of the lunar surface because of communications difficulties.
In a few days Queqiao will enter the moon’s orbit, about 455,000 km( 282,000 miles) from Earth. Queqiao- which entails “Magpie Bridge” and comes from a Chinese folk story in which an arc formed by birds reunites two devotees divided by the heavens- will then act as a bridge between ground stations and the lunar probe.
China plans to send its lunar lander and rover, Chang’e 4, to the dark side of the moon by the end of this year. The lunar probe will carry seeds for growing potatoes and arabidopsis, a flowering plant related to cabbage, for a” lunar mini biosphere” experiment.
” The launching is a key step for China to realise its goal of being the first country to send a probe to soft-land and probe the far side of the moon ,” said Zhang Lihua, manager of the relay satellite project, according to nation news organization Xinhua.
A four-minute video of the assembling of the rocket and satellite, accompanied by dramatic background music, was posted by country media outlets on social media on Monday.” My country is awesome ,” one internet user wrote on Weibo.” Our conquest is the sea of superstars .”
For the past decade, China has embarked on a space program aimed largely at catching up to space powers such as the US and Russia. In 2013, China became the third country to make a soft landing on the moon.
Chinese space officials aim to attempt a human landing in 15 years. The China National Space Administration released a video in April showcasing its planned outpost, a” lunar palace” on the dark side of the moon, with cabins for scientists.
Queqiao will also carry a radio antenna that researchers will use to study the early universe, what astronomers call the” cosmic darknes ages” after the big bang and before the first starrings in the universe were formed.
Being in the shadow of the moon blocks electromagnetic interference from Earth, offering a better view of radio signals in the universe and enabling researchers to “listen” to the cosmos, according to Liu Tongjie, deputy director of China’s Lunar Exploration and Space Program Center.
