It is very difficult for a lunar rover to reach the moon, and it is even more difficult to run on the moon.

If you are not careful, the lunar rover will land the moon with the lander, and then fall into pieces.

Here's a manual Aite of the Peacock Country's Chandrayaan-2.

Even if the landing is successful, the rover may malfunction during use.

Just like Tianxia's original "Jade Rabbit" lunar rover, as Tianxia's first lunar rover, its design mass has reached 140 kilograms, which is a small and exquisite guy in the spacecraft, so many people also call it "Little Rabbit".

At first, it worked normally and completed many experimental tasks, but before entering the second lunar night hibernation, the mechanism control of the lunar rover was abnormal due to the complex lunar environment.

Its research device can then be successfully awakened and functional, but it is unable to move the wheels forward.

The Jade Rabbit was unable to move after more than a month of operation, and speaking of this failure, scientists recalled that there may be two places in the design that were not done properly.

First, the Tianxia aerospace department has an understanding of the lunar environment, but the understanding is not in place, and some designs are not very reasonable.

The second is that in order to compress the weight, the preparation for possible fault handling measures is not in place.

Most people believe that because the lunar rover is light and miniaturized, it is designed to be highly integrated, and the corresponding part is not backed up, and the control circuit of the driving mechanism of all wheels is on a board, and it is possible that the power supply of a driving circuit has a short circuit, so the Yutu loses its ability to move.

According to the simulation tests and speculations on the ground, due to the light miniaturization, the wire is very thin, and it is possible that when it drove over a large rock during its walking, the skin of one of the wires was cut by the stone, and the wire was short-circuited with the support of the lunar rover, which is the most likely.

Since the Jade Rabbit is on the lunar surface, it is difficult to actually verify and cannot go up for maintenance, so it can only become a lesson, and this point should be fully considered in the subsequent design of similar equipment, and effective measures should be taken.

So there was the later Yutu-2 lunar rover.

This No. 2 rabbit has been working since launch and landing, and he has not broken until now, and he is a real model worker.

It was said before that the lunar rover was on the moon, and there was no way to repair it if it was broken, but that was when no one landed on the moon, but when humans landed on the moon, they actually repaired the car on the moon.

At that time, Merriken sent a manned lunar rover to the moon to travel for astronauts.

This "Apollo" lunar rover has a mass of about 210 kilograms, a simple structure, the whole vehicle is similar to the chassis of a normal vehicle, it can also be folded, it is 3 meters long when unfolded, the wheelbase is 2.3 meters, the height is 1.1 meters, and it has 4 wheels.

Each wheel is driven by an engine and powered by a battery, which keeps the tires resilient at temperatures as low as -100°C.

The power supply uses silver-zinc potassium hydroxide disposable batteries, with a driving speed of 10~12 km/h and can carry a payload of about 490 kg.

So this kind of lunar rover is disposable, can not be charged, the farthest record is 35.89 kilometers away, and if you let go of drag racing, the speed will not be limited to 12 kilometers per hour, someone has driven a speed of 17 kilometers per hour.

There are 2 side-by-side foldable seats in front, each with adjustable pedals and seat belts. The front mast is equipped with a large mesh dish antenna. The astronauts control the rover via a T-shaped hand controller located between the two seats.

There is a control and display module on the front of the handle, which shows the current speed, direction, power and temperature conditions.

The Apollo 17 lunar rover, oh, is the same car that raced to 17 kilometers per hour, its front wheel fender was knocked off by the astronauts, due to the low gravity, without the fender block, the wheels can bring up two meters of dust with a turn, which greatly affects the driver's vision.

The astronauts also did not have professional tools and extra fenders to repair the vehicle, so they could only use tape to glue the broken fenders to their original positions, but to repair them on the lunar surface, the car was covered with moon dust, which would destroy the stickiness of the tape and fall off after sticking for a while.

Later, scientists on the ground asked the astronauts to find a few pieces of paper in the manned capsule, and then tape them into the shape of fenders in the manned capsule.

There was very little lunar dust in the manned capsule, so the tape was very strong, and then they used the clips that held the astronomical telescope to attach the paper fenders to the original ones.

Don't say it, it's really easy to use.

It is reasonable to say that it is more difficult to modify the lunar rover on the moon, but in fact it is not very difficult, at least not for aerospace mechanical engineers with complete equipment.

The parts are ready-made, and they are redesigned and manufactured by the scientist of the navigator according to the actual situation, and Tong Anfu only needs to use special tools to install those parts.

Not only himself, but also three other astronauts under his on-site command could complete the installation.

The Navigator's modification of the lunar rover is also very simple, although the weight of the Navigator lunar rover is larger than that of the previous Merriken manned lunar rover, but the length and width are not as long, so there is no two-person seat, and it is directly determined to be a one-person "standing position".

It is not allowed to sit because its newly modified driver's seat is in the back, so in order to increase the visibility, the astronaut is not allowed to sit down, but a standing bracket is added, and there is a hook behind the bracket that can be used to hang other vehicles or simple bodies.

The astronauts stand in the back, with the joysticks at hand, connected to the rover's core control system.

The installation of the battery pack requires the removal of the amateur battery pack that was crudely installed by the robotic arm and replaced it with a new battery pack specially manufactured, which can allow the rover to go further.

"Let's start, Mr. Tang has already taught us all the steps in the illusion space, you should still remember, if there is anything you don't understand or have a gap with your memory, you can ask me."

Aerospace machinery engineer Tong Anfu said with a tool.

"Okay, Ah Fu, let's get started." Cheng Dong said.

Because there is an example of the Merriken lunar astronaut repairing the lunar rover, the navigator prepared a portable lunar dust removal device for them, which has an electromagnetic field and can blow wind, which can easily remove the lunar dust stuck to the key equipment, and then carry out precise installation.

The installation went smoothly and so smoothly that they still had time to chat.

Of course, it's not just nonsense, it's about what they're doing right now.

"I have a feeling that the navigator Tang can do anything, I don't know if it's my delusion, but I really feel that he can do anything, just teach us those precautions for survival on the moon, as if he has been surviving on the moon for a long time."

"I think so too, if you want to talk about his scientific and technological strength, it is known to everyone, but he also knows a lot about the moon, not just that kind of scholar-type understanding, but also the kind of practical understanding, which feels amazing."

"Well, maybe this is a genius, Mr. Tang will definitely go down in history in the future, just like those super celebrities we learned in history books."

And just like that, in less than an hour they were able to convert two cars.

Yes, two cars are enough for the time being, after all, there are only four of them in total, and it is impossible for all four of them to leave the base together and enter the permanent shadow zone.

There were two cars, first let Lin Yang and geologist Peng Zizhen bring back the ice, Cheng Dong and Ah Fu continued to modify the two cars, and then then loaded sandbags.

If everything is normal in the search for ice, their sandcastle progress will not be slow, and if there is danger over there, it will not be in danger for all four people, they can go to the rescue.

After assigning tasks, the two modified cars were attached to improvised bodies, one with tools and one in a sealed storage box, and then set off one after the other.

Sail towards the permanent dark zone.

At the same time on Earth, the Merriken Space Agency has been observing the situation at the Lunar Palace base through a lunar satellite.

There is no way, Tianxia has established a base on the moon first, and they don't know the situation inside, they are in a hurry!
