[Drive, drive, get in the car! 】

[Exciting, this is a lunar rover, let me get on the car!] 】

[I didn't get in the car, hey, I haven't gotten in the car yet. GIF】

[Gan, why can your barrage be launched! ] 】

[Hey, this driver is so familiar, isn't this Captain Tang? ] 】

[How backward is your news, the actual identity of the person is the chief technology officer of the Navigator company! 】

[Damn, isn't he's not 25 years old, is he? CTO at such a young age? 】

[Haha, there are even more exciting, people first learned art, aerospace technology is just a hobby! ] 】

[Hey, why does this setting sound so familiar? 】

[Isn't it, aerospace technology is just a hobby?? Hobby became the CTO of a space company? 】

[No way, if you have talent, you can do whatever you want, and people are the real thing. 】

[Yes, at present, the two rockets of the Navigator and all the lunar equipment are led by others. 】

[Could it be super geniuses like Korolev and von Braun?] 】

[You say so, Captain Tang is only in his twenties, it's really possible! ] 】

[I'll talk about it later, let's see how Captain Tang's driving skills are, don't overturn. ] 】

Tang Chao was ready, he and another moon remote-controlled unmanned vehicle driver checked the various systems, and then prepared to set off.

The live broadcast of this drive is a split screen, one for "7 cars" and one for "8 cars", and then a small picture of two drivers in the corner.

However, although it is a normal split screen, Tang Chao's fame is greater, so there are still many viewers watching him.

After getting ready, the other driver was waiting for his order, and he clicked a few times on the console and said, "For the first time, 10 meters." ”

"Understood, 10 meters."

The driver of the 7th car repeated his command, again pressing a few times on the keyboard.

They manually set a limit that automatically stops when the rover reaches 10 meters.

The two of them drove the lunar rover together, and the corresponding live broadcast screen also began to move forward.

I saw that the lunar rover passed over countless miniature lunar craters and a little bit of moon rock, and it took 8 seconds to walk 10 meters.

Then, the first manual manipulation trial ended.

The command center began to urgently analyze the data.

But most of the viewers who watched the live broadcast ......

【？？？ 】

What happened? 】

[I saw a lonely ......]

In their opinion, isn't it just walking 10 meters?

Can it be so grand?

And walking 10 meters in 8 seconds, is it something to be proud of?

That's too slow, right?

These viewers can't figure out what's going on inside, and it's not surprising that they have a question mark on their faces.

In fact, the 7 and 8 lunar rovers can reach a maximum speed of 10 kilometers per hour, with an average operating speed of 5 kilometers per hour.

This speed is naturally nothing on earth, and it is not as fast as his small red two-wheeled electric speed.

But on the moon, this is the speed of the old driver, once you run, the average lunar rover can't see their tail lights.

Take, for example, a running lunar rover, such as ......

Well, 10 of the 12 lunar rovers that can move on the moon are navigators, so it's obviously not appropriate to take your own lunar rover as an example.

Then the remaining two, the one in the Sakura Country, forget it, for fear of causing international disputes.

Then there are only a few rabbits left in the "Jade Rabbit No. 2".

Tianxia's, his own people, and he is also well-known.

The speed of the Yutu-2 is 200 meters per hour, which is equivalent to ...... per second. 5.6 cm.

It's comparable to the speed at which cherry blossoms fall.

But what does a bunny do?

Its full name should be "Lunar Surface Rover". The biggest advantage of the rover is that it can move!

Don't underestimate this feature, which means that it has a lot more scope and content than a lander that lands at a fixed point.

It carries equipment such as panoramic cameras, lunar radars, infrared imaging spectrometers and neutral atom detectors, and is capable of carrying out a range of scientific research tasks in different regions.

Therefore, its most important mission - scientific research!

This means that most of its energy needs to be used in scientific research instruments, and the motor function only assists these instruments.

What about other similar lunar rovers and Mars rovers?

For the public, the most popular vehicles are Merrican's Spirit, Opportunity and the larger Curiosity rover.

Instead of the White Bear's "Luna Rover 1" and "Luna Rover 2" lunar rover, they are still "nuclear-powered".

No way, Merrican is very good at publicity, and people are still alive.

Both Spirit and Opportunity are in the order of 185 kilograms, which is about the same mass as the 140 kilograms of Yutu-2.

However, the speed of the two rovers is also measured in centimeters per second, and the maximum speed of their "drag racing" is only 5 centimeters per second, while the average speed of movement is 1 centimeter per second.

The self-protection system of this unmanned rover is very rigorous, and they basically stop for 20 seconds every 10 seconds of driving.

They need to check the terrain in front of them and then use their weak "IQ" to calculate to avoid risks and prevent rollovers.

So in fact, the effect of the two rovers is to spend 10 seconds walking forward about the length of a human hand, then stop for 20 seconds to see if there are any potholes in the road ahead, and then continue to try to move forward or change the course.

Even the later "nuclear-powered" Curiosity rover was larger in size, reaching 900 kilograms, but the speed was also at this level.

In fact, if it is used for scientific research, it is not good to be fast, and it is more important to "observe the details" than to "look at the flowers".

Therefore, scientific research patrol vehicles are centimeters per second at this speed level.

Not only do they have to walk slowly to make it easier for them to observe, but sometimes they have to stop and look at a place for a long time.

Yutu 2 is like this, don't look at its speed can reach 200 meters per hour, but that is the speed of "soaring" in a straight line when there are no obstacles.

In fact, it has been running on the moon for more than two years, and as a result, it has not even reached 1000 meters.

Can the lunar rover be fast?

Of course.

Of course, there are fast ones in the lunar rover, such as the "open-top" lunar rover driven by astronauts during the Apollo moon landing.

The fastest of these was the Apollo 17 lunar rover, which traveled 17 kilometers per hour, or 4.7 meters per second.

Created a record for the fastest driving speed of a human on an alien planet.

However, it is only a disposable vehicle, as its energy source is silver-zinc, potassium hydroxide, which is a non-rechargeable battery that is discarded when it is used up.

To do scientific research, it is still necessary for the astronauts to personally get out of the car with the equipment to carry it out.

The advantage of the unmanned rover is that it does not require the astronaut to be present in person, and the disadvantage is naturally that the speed is too slow and too slow.

There is only so much that can be done other than "going with the flow" to obtain scientific data and photographs.

If a scientist discovers something a little further away from it that might be worth researching, and it needs to be studied in the past, it will take a long time.

This time, the 7 and 8 cars are designed to solve this situation.

They can be manipulated on Earth up to 10 kilometers per hour, but the general speed is limited to 5 kilometers per hour, which is about 1.39 meters per second.

The viewing angle of the lunar rover is good and can be seen far away.

Seeing danger from afar, in addition to the prompts given by the computer, the driver can be seen with the naked eye, the human brain can calculate, and can manipulate them to stop in time, even if the signal is delayed, it is only two or three meters forward.

The speed of the remote control car is not "too fast", just make a good prediction.

In this case, the remote-controlled lunar rover will definitely have at least 3 kilometers, not to mention running 5 kilometers per hour.

If scientists find strange places nearby through unmanned lunar rovers or satellites, and want to study them, they can let ground pilots remotely control such lunar rovers to investigate.

The half-ton body can take into account both speed and scientific research, and there are a lot of scientific research equipment installed on it, which is the same as the other six cars in the same batch.

You must know that the mass of those manned lunar rovers is only 431 kilograms, and they also need to carry manned equipment, so they can only use walking tools.
