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 entire road condition is good, with no big potholes or large gravel, then the speed of the "Wangshu" intelligent lunar surface patrol rover will increase rapidly, possibly reaching an hour per hour at the fastest Seventeen or eighteen kilometers.

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 rover 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 complex terrain, the "Wangshu" intelligent lunar surface patrol and exploration vehicle must slow down to pass through, so as to ensure the safety of its patrol and exploration vehicle. After all, this is the moon 380,000 kilometers away. If something malfunctions or even rolls over, no one can help it unless the "Wangshu" intelligent lunar surface patrol rover 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 and long-distance motorized travel, so the distance cannot be too far. After all, this is the first time that the autonomous travel system on the "Wangshu" intelligent lunar surface patrol and exploration vehicle has been used in the field. How it will happen 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 to verify the performance of this autonomous travel system.

Secondly, there are battery life requirements. This is the first time such a long-distance journey has been carried out in the lunar environment. It is a huge test for the power system and battery power system of this "Wangshu" intelligent lunar surface patrol and exploration vehicle. In particular, whether the vehicle-mounted super solid-state battery can be adapted to 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. operation of the system. Of course, the 500-kilometer range may not be accurate because it is greatly affected by terrain. If the terrain is complex and difficult to pass, then the range will definitely not reach 500 kilometers.

Therefore, for the first time practical use, it is better to be safe, and the distance of 110 kilometers is just right. The follow-up step is to gradually increase the travel distance based on test results and task requirements.

Finally, it is the task needs. The mission of their "Wangshu" intelligent lunar surface patrol and exploration vehicle is not only to race on the moon, but also to conduct a series of scientific research and detection tasks. So you definitely can’t just focus on racing and forget your own mission.

This location of 110 kilometers is also a scientific research detection point carefully selected by Zhang Qutong and others. At this point is a small crater, which 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. These meteorite fragments may include some material elements from outer galaxies and deep space, which are of great scientific research value.

Second, this crater was created by a new impact in the past hundred years. This impact also caused a crater that was 100 meters wide and 120 meters deep. The huge impact force will, for example, knock out some soil materials one to twenty meters deep in the lunar soil. This is also an excellent opportunity to study the deep lunar soil, so it is worth exploring.

These three are, of course, to test the obstacle-crossing ability of the "Wangshu" intelligent lunar surface patrol rover, 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 explorations. Crater to gain experience.

And finally, it is to install the lunar soil and geological detectors. One hundred kilometers together is considered a suitable detection distance, so this detector also needs to be placed here to collect relevant data and 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, but gradually the vehicle began to accelerate, and the speed increased to a high speed of 145 kilometers per hour.

Through on-board surveillance cameras and high-speed data transmission networks, Wu Hao and the others in the ground command and control hall came to Shuyuan www. zhaoshuyuan.com 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 picture resolution captured by the surveillance camera is only 1080P or sometimes even 720P. The clarity is not very high, but it is enough for people on the ground to see the driving status of the vehicle and the scenes in front and on both sides during the journey.

The "Wangshu" intelligent lunar surface patrol and exploration vehicle is traveling very fast. Of course, it is on the moon. The speed of fifteen kilometers per hour on earth is slower than a human running, and it is a snail's pace compared to a vehicle.

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 vehicle, the terrain conditions more than 100 meters in front of the vehicle can be detected very accurately. Including whether there are large potholes, large rocks, large undulating terrain, etc.

The intelligent autonomous travel system will autonomously plan the best vehicle travel route based on the detected road surface results to avoid these obstacles and bad road surfaces. If they encounter complex and bad roads, the vehicle will choose to go around or choose a relatively easy 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.
