  The moon has maintained a central role in Chinese culture since ancient times. Not only has it inspired numerous poets, but also generated timeless myths and legends, the most famous of which is about a beauty named Chang’e who resides on the moon with a jade rabbit and her husband Houyi, who shot down nine of ten suns.
  Far from ancient imagination, world scientists have been pouring resources into solving mysteries of the ball of rock 239,000 miles from Earth, hoping to gain a deeper understanding of the only natural satellite of Earth and devise ways to exploit it. Chinese experts have played a big role with a mission named after Chang’e.


  Closer Touch
  China launched two lunar orbiters, Chang’e-1 in 2007 and Chang’e-2 in 2010. With the Chang’e-3 mission in 2013, China became the third country, after the former Soviet Union and the United States, to soft land on the surface of the moon. Later this year, the heavy-lift carrier rocket Long March-5 is supposed to take the Chang’e-5 lunar probe to space from the Wenchang Space Launch Center on southern China’s Hainan Island. Liftoff will herald the dawn of the third phase of China’s lunar program: Return after orbiting and landing.
  The Chang’e-5 probe, designed by the Chinese Academy of Space Technology, is China’s first unmanned spacecraft designed to perform lunar sampling. It will make China the third country to bring lunar samples to Earth and the first in over four decades since the former Soviet Union’s Luna-24 mission in 1976. The Chang’e-5 mission could be tremendously significant for science and serve as a valuable test for future manned lunar missions.
  The return of the Chang’e-5 probe requires delicate coordination between four systems that comprise the eight-ton vehicle: an orbiter, a returner, an ascender and a lander. The lander will put moon samples in a vessel in the ascender after the moon landing. Then the ascender will take off from the moon, dock with the orbiter and then transfer samples to the return module. The orbiter and returner will then head back to Earth. Finally, the returner will re-enter the atmosphere.
  The mission will mark several firsts in China’s lunar program upon completion: first automated moon surface sampling, first moon take-off, first unmanned docking in lunar orbit about 380,000 kilometers from Earth and first return flight at a speed near second cosmic velocity, notes China Aerospace Science and Technology Corporation (CASC).
