It is impossible for Chang'e-4 to change the landing site when it lands on the moon, because scientists have calculated the best landing site to meet tasks such as resource exploration, and it will not be replaced.
-
And it's not possible. Because the location of Chang'e-4's landing on the moon has been set and will not be changed at all, it will always be logged as originally planned.
-
No, because if you change the location, I don't know if it's dangerous to change to **.

Chang'e-4 is a new instrument that takes full advantage of the natural interference-free radio astronomy environment on the far side of the moon, and it has its own link instrument, which can send signals to Earth when the time comes.
-
"Chang'e-4 is located on the far side of the moon and is obscured by the moon, so it cannot communicate directly with the earth. As a result, the Queqiao satellite, which works in tandem with Chang'e-4, has taken on the task of relay communication. Chang'e-4 passed through the Queqiao Bridge to establish communication links with Earth.
-
The Chang'e-4 probe mainly achieved a soft landing on the lunar surface, and the rotation direction of the moon was planned during the flight. It is through satellites that establish contact with the ground.
-
As far as the current situation is concerned, as long as December 16-18, Chang'e-5 can reach Inner Mongolia.
-
At 9:51 a.m. on December 13, the Chang'e-5 orbiter and returner assembly carried out the second moon-to-earth transfer launch, and successfully carried out the ignition of four 150 N engines at about 230 kilometers on the lunar surface, and after 22 minutes of engine shutdown, the orbiter and returner combination successfully entered the moon-to-earth transfer orbit, waiting for follow-up.
-
It is expected that before the 20th of December and after the 16th, Chang'e-5 will successfully return to Earth.
-
Chang'e-5 is a glorious achievement in China's space history, and it was recently launched into space, and when its mission is completed, it will be able to return to Earth.

In order to solve scientific problems on the far side of the moon and expand the understanding of the moon.
The terrain on the far side of the Moon is complex, especially near the South Pole-Aitken Basin, which is rich and colorful, including basalt plains, high albedo zones, deep valley mountains, and so on. Previous lunar exploration missions have mainly focused on the front side of the moon, and the far side of the moon is not well understood. Chang'e-4 landed on the far side of the moon to better understand the structure, landforms, rock composition, etc. on the far side of the moon.
The balance on the far side of the Moon is isolated from the Earth, and there is no radio interference from the Earth. This makes the far side of the Moon an ideal place for astronomical observations and radio science to conduct more in-depth research in cosmology and astrophysics.

At 1:30 a.m. on December 2, 2013, Chang'e-3 launched the Fire World Fighting Arrow - the Long March-3B carrier rocket ignited.
At 21:11 on December 14, 2013, Chang'e-3 landed safely in the area east of Hongwan on the return moon.
Then, almost a decade now, there are still some scientific payloads on Chang'e-3 that are working properly.

At 21:11 on December 14, 2013, Chang'e-3 achieved a "soft landing" on the moon.
The process of Chang'e-3 approaching the lunar surface can be simplified into three stages: turning on the thrust reverser engine to slow down when it is 15 km away from the lunar surface, and hovering when descending to an altitude of h 100 m from the lunar surface to find a suitable landing site on the moon; After finding the moon landing point, Pimo guessed that the velocity continued to decrease, and the velocity decreased to 0 again when it was 4m away from the lunar surface. After that, turn off all engines and make it fall to the surface of the moon in a free-fall motion.
There is no atmosphere on the Moon, and rocket engines and propulsion systems, which traditionally rely on air friction to slow down, no longer work on the Moon. There is a layer of dust on the lunar surface, and when the probe lands on fire, it is likely to stir up lunar dust, which will affect equipment such as optical sensors. Chang'e-3 will rely entirely on autonomous control to complete a one-yard series of actions.

Recently, the news that Chang'e-4 landed on the far side of the moon quickly occupied the headlines of the world, representing that China's aerospace industry has reached a new height. This is yet to be determined.
As the world's first survey vehicle to land on the far side of the moon, Chang'e-4 is of great significance to the entire human race, and will carry out a series of various scientific expeditions on the far side of the moon that humans know nothing about, and also excavate various samples and survey missions on the far side of the moon. Or maybe it's a one-way trip to the moon, left forever on the far side of the moon.
Chang'e-4 will definitely carry out various missions on the dark far side of the moon, and also dig up samples, according to common sense, many lunar survey missions will eventually return to Earth with various samples, and these samples will be analyzed and studied by scientists on Earth, so will Chang'e-4 search for mountains like this? Actually, it won't.
The Chang'e-4 mission is a one-way ticket to the moon, and Chang'e-4 will not die until the end of the mission, and even if the mission is completed, it will not return to Earth.
This is because China's lunar survey mission is mainly divided into surveying around the lunar surface, landing on the moon for surveying, and finally a new vehicle will take it back to the earth, these three steps, Chang'e-4 design drawings do not have a device in the world's returner, that is to say, Chang'e-4 itself is not designed to return to the earth, and scientific researchers also want to do this, but in this case, the technology is more complicated, and it is not in accordance with the steps of China's lunar survey. The best way is to complete the survey mission step by step, it is impossible to return to Earth without a returner, and Chang'e-4 has only been working on the moon.
Of course, in a few years, after China launches Chang'e-5 and even Changhua-6, it will follow the last step of China's lunar exploration, and return to Earth with Chang'e-4 and the previous survey vehicle after landing on the moon. Eventually, they will return to Earth, but not immediately after completing all the tasks.
The ancients found that the moon we see on the earth seems to have always been the same, all the same face, so the side of the moon that we see on the earth is called the front, and the back side of the moon can never be seen on the earth, in fact, the back side of the moon we can see through the probe. >>>More
The general safe period is the first seven days and the last eight days of the menstrual period, commonly known as the first seven and the last eight.
If the lunar exploration is regarded as a black box, then the main task of Chang'e-1 is to verify the deviations of the lunar spatial geography from the actual situation obtained through second-hand data and theoretical exploration before obtaining first-hand information about the moon, and these deviations are compiled into a database to provide a basic database for Chang'e-2's work. >>>More
With the successful landing of the Chang'e-5 return capsule, Chang'e-5's journey to the moon has also come to a successful conclusion. The return of Chang'e-5 brought back two kilograms of lunar soil. These soils have important reference value for the study of the evolution and development of the moon, and the composition of the soil on the moon can also be analyzed through the study of these soils, which lays a certain foundation for human beings to use the lunar resources. >>>More
