Super technology leader

A team of lunar rover galloping in the gray world, the original lunar surface was crushed by wheels, leaving a track of ruts.

If there is no later destruction or other vehicles passing by here, these rutting marks will remain forever, and the soil of the moon is a faithful and reliable historical recorder.

Unlike the earth, which has atmosphere, water, and plants, the soil on the moon, also known as lunar soil, or weathered layer, has a very single physical formation, basically completely shaped by impact.

Large pieces of bedrock were continuously broken, mixed, and turned under the impact of small celestial bodies, and finally formed this fine sand layer on the surface of the moon.

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

So these rutting marks will always remember this historic lunar rescue.

Of course, as long as there is no new large impact crater being hit by asteroids.

The fleet consists of three powered lunar rover, three vehicles strung together with cables. The driver of the first vehicle is Peng Zizhen, the driver of the second vehicle is Lin Yang, and the last vehicle is in the follow mode.

Although they drove faster, they basically walked straight and made big turns. They didn’t have fast small turns, so there was no problem with following them. There were even two unpowered trucks behind the third car. Shelves, containing some supplies.

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

Coupled with the guidance of the exploration satellite in the orbit and the careful observation of the "lead car navigator", it is ensured that they can reach the meeting place at a relatively fast speed.

"Inhale~Exhale~Inhale~Exhale~"

The oxygen is constantly decreasing, and their walking distance is constantly increasing.

"Zizhen, according to the plan, we are now almost one-fifth of the distance away. Let me lead the way."

Lin Yang in the second car said to Peng Zizhen in the lead car.

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

"can."

Because the three cars strung together, the parking was also linked, and soon they stopped as planned.

After the vehicle stopped, they were not in a hurry to get on the road. Instead, they circled the lunar rover and did a simple vehicle inspection.

A worker must first sharpen his tools if he wants to do well.

This is the moon after all, and the places they pass by are all very primitive places, not highways on the earth. In case there is a crack in any place and the self-detection system fails to detect it, I may tell you when Ruthless.

In that way, not only people can't be saved, but oneself will also have to get in.

The inspection was no problem. Lin Yang was standing in the driving position of the leading car. Peng Zizhen got into the second car. The two of them started together with the intelligent unmanned car behind them and continued to drive towards the meeting point.

In fact, their speed is not slow in actual driving. They are not limited to a speed of more than ten kilometers per hour, and they can drive to more than twenty kilometers per hour in a flat terrain and a wide view.

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

The terrain next to the large impact crater is more complicated. The inside of the crater is the area where the impact lava cools, while the outside is the bumps and cracks produced by the extrusion during the impact. Be very careful when using it in this place.

The bumps are easy to say, the big bumps go around, and the small bumps pass directly. Those hidden cracks are the most dangerous existence.

Within 20 minutes of driving out, they suddenly stopped because the lunar rover probe found a suspected crack across the road.

Although it is "suspect", the team can't be reckless and can only stop and check.

During this time, Lin Yang was the pilot, so she went to check.

The inspection is not done with the naked eye, but a shock detector is needed.

Put the device on the ground, it will radiate shock waves at a frequency of several times per second, and then collect the reflected waves, and finally generate a geological model based on these multi-level waves.

After the inspection, it turned out to be a big crack, with only a little fragile structure on it.

Although the crack is not wide enough to make the entire vehicle fall, as long as half of the lunar rover is planted, it will definitely be scrapped, and even the astronauts will be involved in injuries.

The team stopped early and turned well without making sharp turns or backing.

Wait to get around here, and then return to the scheduled route.

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

It is not easy for the Meriken astronauts waiting for rescue, and it is also not easy for the Tianxia astronauts who rushed to the rescue. It is a great favor to extend 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 rescue them!"

"Yes, but it is also because of this danger that you can see who you can count on at the critical moment."

"It is not only dangerous, but also suffering. At present, the longest spacewalk time for human beings is nearly 9 hours, and this time, both sides have to carry out more than one day of'space walks', which is too much for the mind and body. "

"Yes, for more than a day's space walk, eating and drinking Lazarus are all in the spacesuit, let alone the body, the astronauts must be under heavy mental pressure.

"Hey, I don't shudder when I think about it. As an astronaut is really not something ordinary people can be, I can't stand that feeling anyway."

"There is one thing to say, indeed, under such dangerous conditions and mental pressure, you can still go out for rescue. Tianxia's astronauts are really good. This shows that Tianxia is also a reassuring country."

"Navigators are the same. Their equipment also played a key role. Without their equipment, these two Merrican astronauts would be dead."

"Well, if the Navigator's Benyue spacecraft is still on the moon, it can take off directly to rescue the two astronauts."

"But the human science and technology tree is still a bit low. The Navigator is already so powerful. It takes several days for the spacecraft to refuel."

"I think human beings still need to develop together and hold each other. Once we walk out of the earth, we humans are too weak and accidents happen to the moon. It will definitely be more difficult no matter how far away."

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

People were expecting the rescue this time to go smoothly, but bad news suddenly came from Meriken.

The lunar rover fell into a crack and its wheels were directly damaged and unable to move forward.

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