As a key part of the fourth phase of the lunar exploration project, the Chang’e -6 detector opened the world’s first lunar back sample return journey.Previously, humans returned 10 samples on the moon, all located on the front of the moon.

So, what is the difference between the back and front of the moon?Why is it so difficult to go to the back of the moon?

Chang’e 6 officially sail

On May 3rd, the Chang’e 6 detector was successfully launched by the Long March 5 Yaobei Rockets at the Wenchang Space launcher in China, and then accurately entered the ground monthly transfer track.

At present, Chang’e -6 has completed the recent brakes- “Space Bad”, and then entered the moon track and started to fly around the moon. After that, the opportunity will be selected for landing.

Docked by the moon itself, the detector cannot directly realize the measurement and control communication and data transmission with the earth on the back of the moon.More than a month ago, the Lieutenant Lidin Star of the Bridge 2 launched a communication bridge between the moon and the moon.

With the support of Lieutenant Kochi Lieutenant Star, the Chang’e -6 detector will adjust the height and inclination of the ring -moon rail, and select the opportunity to implement the railor returned combination and the lander aspect combination.After that, the lander’s risinger combination implemented the soft landing of the Antarctic Antarctic Basin on the back of the moon.

It is reported that the Chang’e -6 mission is part of the fourth phase of the China Lunar Exploration Project. The task is 53 days and the whole journey is divided into 11 stages.The fourth phase of the lunar exploration includes Chang’e 6, Chang’e VII, and Chang’e 8. The task goal is to initially build the basic type of international moon scientific research station in Antarctica.Earlier, Chang’e -4 has achieved soft landing on the back of the world’s first moon.

Go to the back of the moon

On the surface of the 38 million square kilometers of the moon, humans have only sampled 10 times, 6 times in the United States, 3 times in the Soviet Union, 1 China, and the sampling point is all on the front of the moon.

The landscape of the back of the moon is very different.In addition to robot detectors and a few humans on the back of the moon in history, it has never been seen by most people, and even described as “alien base”.

Scientists believe that the back of the moon is more ancient compared to the front of the moon and has important scientific value. Therefore, Chang’e 6 plans to conduct long -term research on the background samples of the moon, analyze the structure, physical characteristics, and material composition of the moon soil, and strive to obtainUpdate moon scientific data.

In December 2020, Chang’e 5 collected the moon’s Monsters in the Monsters of the Monsters (Mons Rümker), which brought back a sample about 2 billion years ago, and made Chinese scientists discover new details about the moon about the moon.Including more accurately determining the time span of the moon volcanic activity, a new mineral is also found.

Hu Hao, chief designer of the Chang’e 6 mission, introduced that the landing area pre-selected by the mission is the Antarctic Antan Basin on the back of the moon, which is recognized as the largest, oldest and deepest basin on the moon.The choice of landing point comprehensively considers the difficulty of landing, communication difficulty and scientific research value, and is expected to bring back to the long -term lunar samples to help humans further analyze the structure, physical characteristics, material composition, etc.Research.

20 years of lunar exploration project

This year marks the 20th anniversary of the implementation of the monthly exploration project in my country.From Chang’e -1 to Chang’e 6, from the initial exploration Moon Palace to detailed survey, from the moon observation to the monthly inspection secrets, from the remote sensing observation to the sampling return … On the basis of completing the three steps of “detour, fall, and back”,The fourth phase of the lunar exploration project is moving towards the new goal. It will not only implement the monthly back sample and return tasks, but also land on the Moon Antarctica, carry out leap exploration, and carry out various forms of international cooperation with relevant countries, international organizations and international partners.

In addition to discovering new information about the moon, Chang’e 6 still establishes a permanent research station on the moon, the International Moon Research Station (ILRS) long -term plan.The International Moon Scientific Research Station is initiated by China. It will jointly develop and construct a multi -country and will provide outposts for China and their partners to conduct deep space exploration. It can continue to carry out multi -disciplinary, multi -target, and large -scale science of scientific detection, resource development, and technical verification for a long time.And technical activity.

“In the next four years, my country plans to launch three ‘Chang’e’ lunar probe. The construction of the International Moon Scientific Research Station will be implemented step by step in two stages. The basic type is planned to be completed by 2035. Division Wu Weiren disclosed the relevant situation of the International Moon Scientific Research Station at the 2024 China Aerospace Conference held on April 24.

He also said that Chang’e VII will be launched around 2026 to carry out the Moon Antarctic Environment and Resources Survey; Chang’e -8 will be launched around 2028 to conduct a test of lunar resource use tests.
