If the mission succeeds, it would make China only the third country to recover samples from the moon, after the United States and the Soviet Union decades ago.
Named after the ancient Chinese deity of the moon, the Chang-5 probe will test China's ability to buy samples remotely from space, even before more complex missions.
If profitable, the mission will make China exclusively the third nation to have retrieved lunar samples, following the United States and the Soviet Union a long time in the past. The Chang'e 1 and Chang'e 2 orbiters launched in 2007 and 2010, and Chang'e 3 made the nation's first soft moon landing in December 2013, putting a lander-rover duo down on the lunar near side.
The Soviet Union deployed three successful mechanized sample return missions in the 1970s. The last, Luna 24, obtained 170.1 grams (6 ounces) of samples from the 1976 Mare Crimeum, or "Sea of Crys". The other two - a model collector and a climbing vehicle - will touch the Mons Rumker area of the vast Oceanus Procella ("Ocean of Storms"), a vast volcanic plain that has been explored by many lunar missions.
"The Apollo-Luna sample zone of the moon, while critical to our understanding, was undertaken in an area that comprises far less than half the lunar surface", said James Head, a planetary scientist at Brown University.
Subsequent data from the Orbital-Remote Sensing mission have shown a wider variety of rock types, minerals, and ages than are represented in the Apollo-Luna sample collection.
The Chang'-5 mission can help answer questions such as how long the moon was internally active and when its magnetic field - important to protect any form of life from the sun's radiation - disintegrates.
Once within the moon's orbit, the probe will goal to deploy a pair of autos to the floor: a lander will drill into the bottom, then switch its soil and rock samples to an ascender that may raise off and dock with an orbiting module.
This new mission is considered one of the most complicated and challenging for China, since its objective is to bring samples to Earth back from the Moon.
China is set to launch an unmanned spacecraft this week which will land on the surface of the Moon and search for lunar rocks.
Song 4 Pulling the first soft landing in the mysterious distance of the moon, it delivered a lander and rover to this largely unexplored area in January 2019.
Within the following decade, China plans to ascertain a robotic base station to conduct unmanned exploration within the south polar area.
China has also launched since the summer a team to Mars in order to study the planet's atmosphere, environment and geological characteristics.
