Xinyuehu Aerospace Command and Control Hall, Haoyu Technology Linghu Headquarters Park.
The happy atmosphere did not last long, and soon the entire hall became quiet again. For everyone, the most difficult, most uncertain, and risky part of this mission has been completed, but it is not
This means that the task has been completed.
They still have more than 1,200 kilometers to travel, and the entire return journey involves transporting the three-ton gold meteorite star core. Therefore, what unknown problems will they encounter during the return journey? This is in everyone's mind.
There really is no bottom.
Not to mention anything else, let me just say this: If you encounter the same fluffy lunar soil covering or quicksand as you did when you came here during the return journey, it will not be so easy to get out of the trap.
Therefore, every step of the return journey is very important, and no one dares to take it lightly.
Yu Chengwu, who was already free at the side, sat down again and introduced the next work arrangements to Wu Hao and Zhang Jun.
"Next, we will issue instructions to pilot the vehicle out of the crater, then repair and charge it for two hours. In the process, we will complete related maintenance work on the four vehicles."
Speaking of this, Yu Chengwu emphasized: "The most difficult and risky thing among them is to let this engineering transport vehicle carrying the gold meteorite core pass through the access road we built on the edge of the crater before, and then climb up the crater.
.”
"Although we have repaired the access road, you are too sure that the engineering transport vehicle can climb down to carry such a heavy gold meteorite core. So just in case, you need to retreat and prepare to use the winch to pull it.
Come and pull down the engineering transport vehicle transporting the gold meteorite star core, and at the same time provide certain protection to prevent the engineering transport vehicle from sliding or overturning due to the heavy load and low center of gravity."
Just when they slowly reached the top of the crater and everyone thought they had failed and continued on, something unexpected happened.
The seventh vehicle is a small-purpose engineering robot. It is in seventh place, and the order when it came was the same.
The small-purpose engineering robot in front of the car also followed the engineering transport vehicle, using its intelligent robotic arm to push the vehicle forward. When necessary, it dug soil to pad the wheels of the engineering transport vehicle.
soil to prevent the wheels from spinning.
At the same time as Yu Chengwu introduced, the convoy of seven vehicles retreated to the edge of the crater before passing. The same as before, the retreat order of the seven vehicles in the convoy was reorganized.
As the winch increases its power, the vehicle continues to crawl downwards steadily.
Under the crater, the engineering transport vehicle moved downward bit by bit under the tug of the small-purpose engineering robot and the Wangshu-7 lunar surface patrol test vehicle.
That was simply too safe. The Wangshu-7 lunar surface patrol test site must have been pulled with a winch rope from the side and below. I am afraid that the engineering transport vehicle had already rolled over.
As before, the Shiwangshu-7 lunar surface patrol test vehicle was driven at the back. It walked at the back and acted as a pioneer in exploring the path.
But hundreds of people were like that, and the entire small hall was still quiet outside. Everyone was staring at the small screen, for fear of missing something important.
The eighth one was originally a small-purpose engineering transport vehicle, but now it has become an engineering transport vehicle carrying a golden meteorite core. The seventh vehicle at the front has become a small-purpose engineering robot.
It is equivalent to putting the engineering transport vehicle in the middle of the convoy, protected by two small-purpose engineering robots moving back and forth.
As for the small-purpose engineering robot located in front of the engineering transport truck, it is the most difficult at this moment, because it only has to push the truck, and it also has to back up and dig soil to prevent the wheels of the engineering transport truck from slipping.
As the winch under the engineering transport vehicle was turned off and started, the rope gradually tightened and straightened at the front, and the engineering transport vehicle also finished its rapid climb down the slope.
Because the weight was too heavy and the slope of the edge of the crater was too steep, even though a diagonal upward path was built, the entire climb was still very difficult, and it just went by like this.
Zhou Xiangming stared closely at the data on the big screens behind me, giving various instructions with a calm expression.
Immediately afterwards, the Wangshu-7 lunar surface patrol test vehicle passed by and took the lead in climbing down the crater. Then it came to the edge, drove along the edge of the crater, stopped at the position closest to the convoy above the crater, and stopped.
Tighten the rope.
As the engineering transport vehicle increases its power, the entire vehicle quickly climbs down. You can't see through the lenses of several vehicles that while climbing, the gravel and dust picked up by the wheels are rapidly falling upwards.
fall.
A few hundred meters away, the convoy drove slowly to the access road at the edge of the crater and stopped.
The winch of Wangshu No. 7 is slightly loosened and needs to be massaged tightly. The small-purpose engineering robot No. 1 is hooked tightly to the ground, and the winch of the engineering transport vehicle continues to be tightened.
So for a moment, everyone's hearts were lifted again, and a relaxed atmosphere spread outside the command and control hall.
The engineering transport truck carrying the gold meteorite core was crushed and collapsed on the inside of the sidewalk, and then one of the wheels of the entire engineering transport truck was directly suspended in the air.
It is equivalent to the Wangshu-7 lunar surface patrol test vehicle using the rope under its own winch to tie one side of the engineering transport vehicle and applying pulling force to prevent the engineering transport vehicle from turning inward when climbing. At the same time, it also exerts a
The downward force helps the engineering transport vehicle carrying the gold meteorite core go downhill.
"Slow down, slow down, the winch of the Wangshu-7 lunar surface patrol test vehicle will increase with a small amount of force, and the vehicle will move forward, in order to make the vehicle overturn!"
The first thing to move was the Wangshu-7 lunar surface patrol test vehicle. The winch on its back stretched out the rope again, and then the small-purpose engineering transport vehicle hung the hook at the top of the rope to the anchor under the body of the engineering transport vehicle.
point.
Then came the small-purpose engineering robot in seventh place. It pulled the rope extending from the winch on the back of the engineering transport vehicle and climbed to the top of the crater.
Although the distance of the entire slope is not far, only about 70 or 80 meters, the entire retreat process is very full. It is really climbing down quickly, like a snail, which makes people watch it slowly.
Seeing that scene, everyone in the small hall immediately fell into a state of relaxation.
Because it was climbing empty, the small-purpose engineering transport vehicle climbed very nervously with its weak own power. It climbed down the crater very slowly, stopped at a section of the sidewalk, and then used its own power to climb up the slope.
The intelligent robotic arm it carried dug a hole in the ground and hooked the bucket tightly outside the hole, forming an anchor point to prevent the small-purpose engineering robot from being pulled up due to too small a pulling force.
