Under the intense attention of everyone, the "Wangshu" intelligent lunar surface inspection and exploration vehicle has completed a series of preparations and related scientific research work at the landing site, and will soon start its own journey to the moon.
According to the previously planned route, the "Wangshu" intelligent lunar surface patrol rover will travel to the Manilius Crater in the northeast.
This time, the "Wangshu" intelligent lunar surface patrol rover will travel approximately 110 kilometers and is planned to take eight to nine hours.
Because the entire journey is entirely driven by the "Wangshu" intelligent lunar surface patrol and exploration vehicle, the specific actual route and speed are determined by the "Wangshu" intelligent lunar surface patrol and exploration vehicle, so
As for the specific travel time, there is currently no accurate figure.
However, based on the average traveling speed of the "Wangshu" intelligent lunar surface patrol rover of about 13 to 14 kilometers, it will take about eight or nine hours. If the overall road conditions are good and there are no big potholes,
If there are no large gravels, then the traveling speed of the "Wangshu" intelligent lunar surface patrol rover will increase rapidly, and may reach a maximum of 17 or 18 kilometers per hour.
However, if you encounter some difficult terrain with many potholes and gravel during the trip, then for the sake of driving safety, the speed of the "Wangshu" intelligent lunar surface patrol and exploration vehicle will definitely have to be slowed down, and maybe even
It is possible that it will drop to one or two kilometers per hour or even hundreds of meters.
During the development process of the "Wangshu" intelligent lunar surface patrol and exploration vehicle, Wu Hao made a request that the exploration vehicle should be able to go fast and slow down. When encountering some complexities
Under the terrain, the "Wangshu" intelligent lunar surface patrol and exploration vehicle must slow down to pass, so as to ensure the safety of its patrol and exploration vehicle. After all, this is the moon 380,000 kilometers away. If something happens
If there is a malfunction or even a rollover, no one can help the "Wangshu" intelligent lunar surface patrol and exploration vehicle unless it saves itself.
Why travel 110 kilometers? This is also a decision made after careful research by the scientific research team. On the one hand, this is the first high-speed long-distance motorized travel, so the distance cannot be too far. After all, this is the "Wangshu" intelligent moon
This autonomous travel system on the lunar patrol and exploration vehicle has been used in the field for the first time. Its performance is still unknown, so the distance cannot be too far. Of course, it cannot be too close. If it is too close, sufficient test data will not be obtained.
, thus unable to verify the performance of this autonomous traveling system.
Secondly, there are the requirements for battery life. It is the first time to travel such a long distance in the lunar environment. The power system and battery power system of this "Wangshu" intelligent lunar surface patrol and exploration vehicle are all
A huge test. Especially whether the vehicle-mounted super solid-state battery can be used in the real lunar environment remains to be tested.
Although the super solid-state battery on this vehicle can support the "Wangshu" intelligent lunar surface patrol and exploration vehicle to continuously travel for more than 500 kilometers at a time, this is still a conservative calculation, and sufficient power needs to be left to supply other detections.
The operation of the system. Of course, the 500 kilometers of battery life may not be accurate because it is greatly affected by the terrain. If the terrain is complex and difficult to pass, then the battery life will definitely not reach 500 kilometers.
Therefore, for the first time of practical use, it is better to be safe. The distance of 110 kilometers is considered just right. Subsequently, the travel distance will be gradually increased based on the test results and task requirements.
Finally, there is the mission requirement. The mission of their "Wangshu" intelligent lunar surface patrol and exploration vehicle is not only to race on the moon, but also to carry out a series of scientific research and detection tasks. So it must not just focus on it.
Racing and forgetting its own mission.
This location of 110 kilometers is also the scientific research detection point carefully selected by Zhang Qutong and others. The location of this point is a small crater, and it is also a new small crater formed in the past hundred years.
The diameter of this crater is about one hundred meters, and its depth is about ten or twenty meters. Zhang Qutong and others believe that there may be meteorite fragments preserved in this crater, and these meteorite fragments may include some from outside.
The material elements of galaxies and deep space are of great scientific research value.
Second, this crater was created by a new impact in the past hundred years. This impact also created a crater that is 100 meters wide and 120 meters deep. The huge impact force, for example, will blow the lunar soil 100 to 20 meters deep.
Some deep soil materials were impacted out, and this is also an excellent opportunity to study deep lunar soil, so it is worth exploring.
These three are, of course, to test the "Wangshu" intelligent lunar surface patrol rover's ability to overcome obstacles, especially its ability to enter and exit craters, climb over craters, and travel inside craters.
This crater is not big or deep, and the crater formed by the impact is not high. It is suitable for testing the obstacle-surpassing ability of the "Wangshu" intelligent lunar surface patrol and exploration vehicle, and provides a basis for larger and deeper subsequent exploration.
Craters gain experience.
And finally, it is to install the lunar soil and geological detector. One hundred kilometers together is a more suitable detection distance, so the detector also needs to be placed here to collect relevant data information here.
Under the watchful eyes of Wu Hao and others, as relevant instructions were issued, the "Wangshu" intelligent lunar surface patrol and exploration vehicle began to move. The speed was very slow at first, and gradually the vehicle began to accelerate, and the speed increased to
A highway of 145 kilometers per hour.
Through on-board surveillance cameras and high-speed data transmission networks, Wu Hao and others in the ground command and control hall can also watch the progress of the "Wangshu" intelligent lunar surface patrol and exploration vehicle in real time.
In order to ensure the continuity of the picture, the definition of the picture taken by the surveillance camera is only 1080P or sometimes only 720P. The definition is not very high, but it is enough for people on the ground to see the driving status of the vehicle and the front and sides of the vehicle during the movement.
scene.
The "Wangshu" intelligent lunar surface patrol rover travels very fast. Of course, it is on the moon. On the earth, the speed of fifteen kilometers per hour is slower than that of a human. Compared with
It's like a snail's pace for vehicles.
But in a complex environment like the moon, such a speed can be said to be very fast, and it is like racing.
Through the image recognition system and radar detection system in front of the "Wangshu" intelligent lunar surface inspection and exploration vehicle, it can very accurately detect the terrain conditions more than 100 meters in front of the vehicle, including whether there are large potholes and large rocks.
Blocks, large undulating terrain, etc.
The intelligent autonomous driving system will autonomously plan the best vehicle route based on the detected road surface results to avoid these obstacles and bad road surfaces. If it encounters complex and bad road surfaces, the vehicle will
Choose a detour or choose a relatively easier route.
At the same time, the vehicle will also conduct large-scale identification and judgment based on the orbiter and pre-stored satellite maps of the lunar surface, and try to avoid some areas with complex terrain as much as possible, unless the mission requires manual designation.
