It touched down on the far side of the moon at 10: 26 a. m. Beijing
13、 Time, becoming the first spacecraft soft-landing on the moons unknown side never visible from Earth.

14、, meaning Magpie Bridge, after a Chinese legend (传说 ) , was launched on May 21, 2018, and became the first communication satellite operating in the halo orbit, nearly 500, 000 km from the earth. It can also provide communication for probes from other countries. The relay satellite will also be used
15、for scientific and technological experiments. The maximum distance between the satellite and the Change-4 probe on the far side of the moon is 79, 000 km. The satellite processes data from the probe and sends it to Earth. The satellite can stay in its orbit for a long time due to its relatively low
16、fuel consumption, as the earths and moons gravity balances its orbital moving. While in orbit, it can “see” both the earth and the far side of the moon. The concept of using a relay satellite in the halo orbit was first put forward by U. S. space experts in the 1960s, but was realized by Chinese space engineers. Researchers hope to u
