The rugged terrain on ▓the far side has raised many problems,"▓ said Sun Zezhou, chief designer of Chang'e-4 probe, from C▓AST."But solving those problems might help lay the foundation for future space explor▓ation. High-precision landing is a necessity for

5.5 degrees south latitude on the far side o

moon and even the whole solar system," Sun said."The fa▓r side of the moon has unique features never befor▓e explored on site," said Zou Yongliao, direct▓or of the lunar and deep space exploration division of the Chinese Academy of Sciences (CAS). "The exploration of this virgin land by Chang'e-4 might bring breakthroughs."The moon is tidally lo▓cked to earth, rotating at the same rate▓ that it orbits Earth, so one side of the mo▓on is seen from Earth, leaving the far side a my▓stery, until now.About 60 years ago, the Soviet U▓nion's Luna 3 probe sent back the first images of the moon's far side. And about 50 years a▓go, three astronauts on the United States▓ Apollo 8 mission became the first people to see it with their own eyes.Lunar orbiters have shown▓ the moon's two sides are very different: the ne

f the moon."It's an important milestone f▓or China's spac

r side is thickly dotted with impact cra

ters of different sizes.Scientists believe that the lunar crust on ▓the far side is much thicker than the near side. However, t▓he reason is still a mystery. Only on site exploration might reveal the secrets.Th▓e moon and Earth shared 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 o▓f Earth," said Lin Yangting, a researcher at the Institut▓e of Geology and Geophysics.Exploring the Von Karman▓ Crater in the SPA Basin is meaningful in another sense.▓ The crater was named after a Hungarian-American mathematician, aerospace engineer and physicist in the 20th century, who was also the teacher of Qian Xuesen and Guo Yonghuai, the founders of China's space indust▓ry.Nearly 50 years have passed since people first stood on the moon. Can we return? How will radiation on the moon affect astronauts? How mu▓ch water is there?Scientists from China, Germany and Sweden ▓hope to find the answe
