ared a similar "childhood." But traces of the remote past on Earth have been erased by geological▓ activities. "The moon might provide some insights to the ▓early history of Earth," said Lin Yangting, a res
earcher at the Institute of Geology and Geophysics.Exploring the Von Karman Crater in the SPA Basin is▓ meaningful
in another sense. The crater was na▓med after a Hungarian-American mathematician, aerospace▓ engineer and physicist in the 2
0th centur▓y, who was also the teacher of Qian Xuesen and Guo Yonghuai, the founders of Chin▓a's space industry.Ne
arly 50 years have passed since people first stood on the moon. ▓Can we return? How will radiation on the moon af
fect astronauts? How much water is there?Scientists from China, Germany and Sweden hope to find the answers throug
h Chang'e-4▓, and make preparations for people to return to the moon.Professor Robert Wimmer-Schweingruber, of the Institute of Exper
imental an▓d Applied Physics of Kiel University in Germany, said▓ that preparing for future human exploration of the
m▓oon was an excellent idea."If astronauts come back to Earth, the radiation on the moon is the ▓only danger that remains
in their body. So we need to understand that," he said.Johan Koe▓hler, head of Solar System Science and Space Situ
ation▓al Awareness, Swedish National Space Agency, said exploration of the far side of the moon was a great achie
vement by China. "We are very hap▓py to be a part of it.""There is a theory that water on the surface of the moon i
s formed by the interaction of solar wind with the surface regolith. So this is something that Swedish scientists together with Chin
ese scientists want to answer," said Koehler.The C▓hang'e-4 mission, including the probe, the relay satellite Queqi
ao and a micro satellite orbiting the moo▓n, is equipped with four payloads developed through in▓ternational coopera
tion, providing more oppo▓rtunities to the world's scientists and combining human expertise in space exploration."I
think one of t▓he beauties of space science is that we do cooperate internationally. Space scien▓ce to me is something important, als
o as a message of peace worldwide," Wimmer-▓Schweingruber said.For astronomers, the far side of the moon is a pla
ce of ideal tranquility, as the body of the moon shields against radio interference from Earth. From there, they can study
the origins and evolution of stars and galaxies, peering into▓ the dawn of the universe.Chang'e-4 ca▓rries low-fr
equency radio astronomical instruments developed by Chinese and Dutch scientists. "Condu▓cting such observation on
the moon's fa▓r side is a long cherished goal of astronomers, and could fill gaps in astronomical observation,"said
Zou.The probe also took six live species -▓ cotton, rapeseed, potato, arabidopsis, fruit fly and yeast - to the lifeless environment
to form a mini biosphere, which is expected to produce the first flower on the moon.Chinese space engineers also
plan to get data by constantly measuring temperatu▓res on the surface of the moon."Expl▓oring the far side of the
moon is o▓ne contribution China is making to the world. Although we still don't know what we
might find, this exploration might influe▓nce several generations," said Shen Zhenron▓g, a d
esigner of the lunar rover.Wu Weiren said: "Exploring the unknown is human▓ nature. The moon is a mysterious world to us▓. We have a responsibility to explore and to understand it. Exploration of the moon will also deepen our understanding of Earth and ourselves."Please scan th▓e QR Code to follow us on InstagramPlease scan the QR Code to follow us on WechatBamboo fills pandas' stomachs and farmers' wallets in SW ChinaBamboo fill
