Chang 'e V is scheduled to be launched in late October of/kloc-0, and the launch location is 165438+. How does it realize sampling return?

The main task of Chang 'e V is to sample and return to the moon. It must face four main technical problems: sampling, ascent, docking and high-speed reentry. According to the recent design scheme, Chang 'e-5 is composed of orbiter, returner and lander, among which the lander will make a soft landing on the lunar surface, and automatically carry out operations such as lunar sampling and sample packaging. The sample will be carried into the lunar orbit by the ascending section of the lander, docked with the orbiter on the lunar orbit, and transferred to the inside of the returner. Finally, the orbiter will carry the returner to ignite and maneuver, and return to Earth directly from the lunar orbit, and the returner will be separated before re-entry.

165438+1October 17, the Long March V carrier rocket and Chang 'e V probe were vertically transported to the launch area after completing the final assembly test in the technical area at Wenchang Space Launch Site, China. The launch is scheduled for late June165438+1October.

The Long March 5 Wu Yao carrier rocket was safely delivered to Qinglan Port in Wenchang, Hainan by Roy transport fleet in late September, and delivered to Wenchang Space Launch Site in China by road transport. Since then, according to the test launch process, the rocket has successively completed various preparatory work such as final assembly and testing. 165438+1October17th morning, the mobile launch platform drove out of the vertical test building of the launch site, and after running smoothly for about 2 hours, the Long March 5 carrier rocket was safely transferred to the No.1 launch station of the launch site. Subsequently, the rocket function inspection and joint test are completed. After the final state is confirmed, the rocket will be filled with propellant and launched according to the procedure.

This mission is the second application launch of the Long March 5 series of launch vehicles. It has successfully launched China's first Mars exploration mission, Tianwen-1. Chang 'e V mission is the sixth mission of China's lunar exploration project. Realizing the automatic sampling and returning of the lunar surface is helpful to deepen the scientific research on the origin and evolution history of the moon, which is one of the most complicated and difficult tasks in China's space field so far. The lunar exploration project is another milestone in the development of China's space industry after the success of artificial earth satellites and manned space flight, and it has opened an era for China people to explore the mysteries of the deep space universe. On June 24th, 2007, 10, the Chang 'e-1 satellite was put into the scheduled orbit by the Long March III Jiayao 14th rocket, which opened the curtain for China people to explore the moon and realized the zero-window launch for the first time. On June165438+1October 12, 2008, the full moon image taken by Chang 'e-1 was released; On March 1 day, 2009, Chang 'e-1 satellite hit the moon as scheduled, marking China's entry into the ranks of countries with deep space exploration capability in the world.

20 10, 10, 1, the Chang' e-2 satellite was put into the earth-moon transfer orbit by the Long March-3 C-7 rocket, which set a new height for China's lunar exploration project, and it was also the first time that the China rocket directly put the satellite into the earth-moon transfer orbit. 20 13 12. The Chang 'e-3 probe carrying China's first lunar rover was successfully launched by the Long March-3 rocket, marking the second step of the lunar exploration project. 20 13 12 14 and Chang' e-3 successfully landed on the moon, realizing the first soft landing of China's spacecraft, and carrying out patrol survey and scientific exploration.

In addition, it is still unknown whether the Martian soil is safe and whether it will affect the earth's environment after being brought back to Earth. Don't underestimate the soil, it is likely to have a butterfly effect. Therefore, before scientists' research on Mars reaches a certain level, we dare not get Martian soil at will, which may bring disaster to the earth.

In fact, this also reflects the rigor of scientists and the high tension in the exploration of the universe. After all, in front of the universe, human beings are so small. What we have to do is to respect and explore, rather than blindly follow one's inclinations. This is not only the destruction of the universe, but also the destruction of the earth.
