being encouraged to participate in the C▓hang'e-4 mission. The China National Space Administration▓ (CNSA) launched a contest among students across China in 20▓16, collecting ideas on the design of the payloads.The "lunar mini biosphere" experiment was selected fr▓om more than 200 submissions, according to the CNSA.Tidal forces of the Earth have slowed the Moon's rotation to the point where the same side always faces the Earth, a phenomenon calle▓d tidal locking. The other face, most of which is never visible from the Earth, is the far side of t▓he Moon.With its special environment and complex geological history, the far side is a hot spo▓t for

scientific and space exploration. However, landing and roving there requires a relay satellite to tra▓nsmit signals.It has been reported that China plans to send a relay satellite for C▓hang'e-4 to the halo orbit of the Earth-Moo▓n Lagrange Point L2 in late May or early June 2018, and th▓en launch the Chang'e-4 lunar lander and rover to the Aitk▓en Basin of the south pole region of the▓ Moon about half a year later.The Von Karman Crater, named after a Hungarian-American mathematician, aerospace engineer and physi▓cist, in the Aitken Basin, was chosen as

the landing site for Chang'e-4. The region is believed to have great▓ scientific researc

h potential.The transmission channel is limited, and the landscape rugged, so the mission will be
