A team of lunar rovers are speeding in the gray world, the original moon surface is crushed by wheels, leaving behind ruts.

Without later damage or other vehicles passing by, these ruts will remain forever, and the moon's soil is a faithful and reliable historical recorder.

Unlike the earth with atmosphere, water and plants, the soil on the moon, that is, lunar soil, or weathering layers, its physical properties are very single, and are basically completely shaped by impact.

Large bedrocks were constantly broken, mixed and flipped under the impact of small celestial bodies, and finally formed this delicate sandy layer on the surface of the moon.

Although solar wind and cosmic rays can also change some of the characteristics of lunar soil, this effect is more about chemical composition, such as the formation of hydroxyl groups and water in lunar soil particles, which basically does not affect the physical shape.

So these ruts will always remember this historic lunar rescue.

Of course, as long as the asteroids are not impacted here, a new large impact crater will be generated.

The fleet had a total of three powered lunar rovers, and the three cars were strung together with cables. The driver of the first one was Peng Zizhen, the driver of the second one was Lin Yang, and the last one was in the follow-up mode.

Although they drove faster, they basically walked straight lines and turned big corners, and did not have fast small bends, so it was not a big problem to follow. Even the third car was dragging two unpowered truck frames and loading some supplies.

The three cars are strung together to prevent the head truck from accidentally falling into the crack. After all, there are two cars behind it and there are truck frames. If the head truck has an accident, you can easily pull it up.

Coupled with the detection satellite guidance on orbit and the careful observation of the "head-car pilot" to ensure that they can reach the place where they meet at a relatively fast speed.

"Soon~soon~soon~soon~soon~soon~soon~soon~soon~soon~soon~soon~soon~soon~soon~soon~soons

The oxygen is decreasing and their walking distance is increasing.

"Zizhen, according to the plan, we have walked almost one-fifth of the way now. Let me lead the way."

Lin Yang in the second car said to Peng Zizhen.

"Okay, Sister Lin, this is a straight line section. We start to slow down in 30 seconds, and the speed drops to zero within 20 seconds." Peng Zizhen said.

"Can."

Because the three cars were strung together, parking had to be linked, and soon they stopped as planned.

After the vehicle stopped, they did not rush to get on the bus, but instead circled around the lunar rover and simply checked the vehicle.

If you want to do a good job, you must first sharpen your tools.

After all, is this the moon? The places they pass by are all very primitive? It is not the expressway on Earth. If there is a crack in somewhere and the self-detection system cannot detect it? Maybe when will I give you a ruthless one?

Not only can people not be saved? Even I have to get in.

Is there any problem with the inspection? Lin Yang was standing in the driving position of the first car, and Peng Zizhen got into the second car? The two started together with the smart unmanned vehicle behind and continued to drive towards the junction point.

In fact, their speed is not slow when driving? It is not that they can drive more than ten kilometers per hour if they die. They can drive more than twenty kilometers per hour with a flat terrain and wide view.

The ground is undulating and when it is next to a large impact crater, they will drive up to ten kilometers per hour, or even slower.

The terrain next to the large impact crater is relatively complex. The pit is a cooled area for impact lava, while the outside is the bumps and cracks caused by squeezing during impact? Be very careful when exercising in such places.

It’s easy to say that the bulge is around, the large bulge is around? The small bulge is directly opened? Those hidden cracks are the most dangerous.

Less than 20 minutes after driving out? They suddenly stopped because the rover's probe found something suspected to be a crack and crossed the way forward.

Although it is "suspected", the convoy cannot be reckless and can only stop and check.

Lin Yang was a navigator during this period, so she went down to check.

The inspection is not done with the naked eye? Instead, it requires a vibration detector.

When the device is inserted into the ground, it will radiate vibration waves outward at a frequency of several times per second, then collect the reflected fluctuations, and finally generate a geological model based on these multi-level fluctuations.

After inspection, there was indeed a big crack, with only a little fragile structure on it. If the car drove up, it would be a bad thing.

Although the width of the crack is not enough to make the entire vehicle fall, as long as half of the lunar rover falls into it, it will definitely be scrapped, and even astronauts will be implicated and injured.

The convoy stopped early and made a turn, so there was no need to make a sharp turn or backwards.

Wait until you bypass this place and return to the scheduled route.

All of this was seen by the audience watching the live broadcast.

It is not easy for the Meriken astronauts waiting for rescue, but it is also not easy for the Tianxia astronauts who rushed to rescue. It is a great favor to be able to lend a helping hand at this time.

"This is too dangerous. If it weren't for today, who would have thought that humans could travel more than 400 kilometers on the moon to carry out rescue!"

"Yes, but because of this danger, we can see clearly who we can count on at critical moments."

"It's not only dangerous, but also painful. At present, the longest spacewalk for humans is nearly 9 hours a day, and this time, both sides have to conduct more than a day of "spacewalk", which is too heavy for the spirit and the body."

"Yes, I have been walking in space for more than a day, eating, drinking, defecating and urinating in the space suit. I won't talk about my body for now, and the astronauts will definitely have a lot of mental pressure."

"Hey, I feel chilled when I think about it. Astronauts are not something that ordinary people can do. I can't stand that feeling anyway."

"To be honest, indeed, under such dangerous situations and mental pressure, Tianxia's astronauts are really good, which shows that Tianxia is also a reassuring country."

"The same goes for the pilots, their equipment also plays a key role. Without their equipment, these two Meriken astronauts would be dead."

"Well, if the Pilot's Moon-Roading spacecraft was still on the moon, it could take off and rescue the two astronauts."

"But the human technology tree is still a little lower. The pilot is already so powerful. It takes several days for the spacecraft to replenish fuel."

"I think humans still need to develop together and hold each other hostage. Once we walk out of the earth, we humans are too weak, and accidents will happen on the moon. It will definitely be even more difficult to get farther away."

"I hope the astronauts can be rescued safely, and I hope that the two countries can cooperate after this incident and lead mankind to the stars."

People were looking forward to the success of this rescue, but bad news suddenly came from Meriken.

The lunar rover fell into a crack and the wheels were directly broken and could not move forward.

Suddenly, the hope of the "whole village" was placed on the rescue team.
