BEIJING: Two parts of the latest Chinese space mission to the moon, the Chang'e 5, the Orbiter and the Ascender, have successfully orbited each other by orbiting the moon. Has set a new record.
According to Chinese and international media, this is the first time in human history that two objects in orbit around the moon have been automatically and successfully connected.
This success is also significant because, at the time of connection, these two parts of the Chang'e 5 were moving at an extraordinary speed of 5,760 kilometers per hour, and the slightest mistake could have caused severe collisions and destruction between the two parts.
Extremely sensitive and careful mission
China's "Chang 'e 5" space mission is the first in the last 44 years to collect soil and rock samples from the moon and bring them back to Earth. According to Wikipedia, the former Soviet Union's "Leona 24" was the last space mission to collect soil samples from the moon and return them to Earth in 1976.
The "Chang' e 5" mission, which took off on November 24, 2020, consists of four parts: four modules: an orbiter, a module landing on the moon, and a sample from the moon back into orbit. Ascendant module, and module (Returner) to deliver these samples safely to the ground.
Chang' e 5 "lander" landed on Mount Roemker, a lunar volcanic field, on December 1, from where he collected about two kilograms of lunar soil and rock samples. Scientists say that this place is very "new", meaning that the soil and rocks here are only 1.2 billion years old.
The samples taken from here were safely transferred to the "Essander" module, which was attached to the "Lander". Meanwhile, a Chinese flag was also planted on the moon by a robotic arm from "Lander". Thus, after the United States, China became the second country to put its flag on the moon.
After the whole operation was completed, the "Lander" remained on the surface of the moon, while the "Essander" flew away from it and began to move towards the "Arbiter" module.
Reaching the desired position in orbit around the moon, Ascender and Arbiter began to approach each other very slowly because this was another important stage of the mission in which there was no room for error.
These two parts of Chang Yi Fi are connected by special robotic arms. Samples of lunar soil and rocks, which were enclosed in the Essander module, were then carefully transferred to the "Returner" module attached to the same orbiter.
Thus, this sensitive stage was successfully completed and a new history was made in space research. Sometime later, the Ascender module was also separated from the Chang'e 5, and the mission is now orbiting the moon.
The rest of the Chang'e 5 mission is expected to launch its rocket on December 12 or 13 and enter orbit shortly after. According to the plan, Chang E-Five will orbit the Earth by December 17 and reach a certain point, where its "return" module will separate from it and start falling towards the Earth.
Carefully controlling its speed, it will land in a desolate plain in Inner Mongolia called the "Siziwang Monkey". It is important to note that the distance between the Earth and the Moon is about 380,000 (three hundred and eighty thousand) kilometers, which is why this work had to be done in a completely automatic manner.
Chinese astronomers say the process of connecting the two modules to orbit the moon at extremely high speeds had to be automated as well as extremely accurate. And the successful completion of this phase is undoubtedly a historic moment.
This and other similar achievements have highlighted the possibility of timely completion of plans to send Chinese astronauts to the moon by 2030, while some new information on the structure and composition of the moon is expected to be obtained through these models. ۔
