Industrial survey, it turned out that the sweater was worn inside out?

Chapter 488 Mars, there is someone!
The images in his mind slowly dissipated, leaving only the twinkling stars in the ship's porthole filling his mind.

After an unknown amount of time, Li Zixuan heard the sound of the spacecraft's announcement again.

"All members of the pioneering team please be aware that the spacecraft is about to arrive on Mars. Please prepare for landing and secure your body to prevent injuries from falling."

The spacecraft's broadcast was repeated twice more, followed by a jitter, and not long after, dull collision sounds came from various parts of the spacecraft.

After that, everyone on the spacecraft felt a kind of solidity, which was the solidity of the spacecraft landing on the ground and colliding steadily with the ground.

The spaceship landed.

After a brief period of silence, the people in the crew cabin untied the fixtures and hurriedly ran to the ship's portholes, looking at the earth outside through the spacecraft's narrow portholes.

Different from the planet seen in space, outside the porthole, there is only a patch of yellow, gray and yellow, and a strong wind blows from time to time. The first impression is that of boundless desolation and silence. And death.

At this time, a young man lying on the porthole suddenly shouted: "Zixuan, look at this composition, look at this scenery, the desert is solitary and the smoke is straight, the sun is setting over the long river, it's so beautiful!"

"Mars is here at the right time."

After the young man finished speaking, he received no response. He was stunned for two seconds before slowly turning around. Then he saw a dozen people surrounding him, and their eyes were full of curiosity.

Looking at them, the young man blinked and asked curiously: "You guys?"

Li Zixuan, who was closest to him, also spoke at this time and asked: "Which Zixuan is your name?"

While asking questions, he pointed his right index finger at himself, stayed there for a moment, and then pointed at other people. His finger moved in a circle, and each person he pointed to reported his or her name.

They are all Zixuan.

At the porthole, the young man rolled his eyes, pointed at his nose and said, "My name is Chen Yuxuan."

After a brief interlude about their names, these young people quickly became friends. After a short rest, they also received new tasks.

Explore the canyon below the landing site!
Here, the way humans use it is still the same as on the moon. First find a suitable place, drop the building materials, and modify it to serve as the initial base.

Then, based on this, slowly expand the base.

As for improving the environment of the entire planet, the entire Space Force has never considered this idea from beginning to end, because the manpower and material resources required to invest are not something that current humans can afford.

The first task now is to make the sword and hold it in your hand, and then slowly work on other things.

In the spaceship, after checking the equipment on his body and the robot he carried with him, Li Zixuan followed the captain in a group of five and rappelled down into the canyon below.

The canyon is very deep, more than 100 meters long.

After falling to the bottom of the valley and looking up at the crack in the sky, Li Zixuan suddenly felt a hint of fear in his heart.

If the mountains on both sides of the canyon suddenly collapse, then all of them will be turned into pies, the kind of pies that have not been cleaned up.

hiss--

Taking a breath of cold air, Li Zixuan shook his head vigorously, threw the idea out of his mind, and turned around to start operating the equipment.

The principle of the equipment in hand is very old. It mainly uses the equipment to emit high-frequency shock waves. Then these shock waves will travel through the rock mass and will be reflected to varying degrees depending on the materials they encounter. These reflected waves can help them understand the underground rock structure. To build a base here, they must confirm whether there are cavities below, and also confirm whether these cavities below can be used.

Soon, the seismic waves responded. The seismic waves showed that in front of their team, near the mountain on the right, there was a cavity about two meters high. This cavity extended far away.

Even the seismic waves cannot clearly see the entire cave.

Seeing the data displayed by the device, team leader Liu Ziang turned off the device, then started it again, sending seismic waves again.

Ten minutes later, the latest data showed that there was indeed a hole ahead, and the hole was still very deep. It was only blocked on the surface of the hole, close to the mountain, and required manual digging.

After recording the data, Liu Ziang pressed the earphone and said: "This is Team 12. We have discovered a hole and now we are asking for permission to explore."

The next second he finished speaking, a new order came through the team's public communication channel.

"Squad 12, the headquarters allows exploration, but you must keep signal relay stations along the way, and pay attention to safety."

"Understood!" In response, Liu Ziang led the people to the front of the cave and looked at the rocks covering the entrance of the cave. The captain did not hesitate and raised his right hand. The armor on his right hand deformed and a drill bit poked out from inside the armor. Only his thumb Big and small, but when rotated, it looks particularly terrifying.

Put the drill bit close to the bunker and spin wildly, breaking the rock and drilling holes.

After drilling the holes, Liu Ziang took a step back. Li Zixuan stepped forward, took out the small explosives he carried, filled them one by one, stepped back, and counted down to 321 to detonate.

Under the attack of explosives, the rock did not hold up for long. In less than half an hour, a huge hole was exposed.

It was pitch dark inside the cave. Liu Ziang turned on the light and took a look inside.

The inner wall of the cave entrance is very smooth, the light on the armor sweeps across, and the camera also captures the scene inside the cave and transmits it back to the spacecraft.

The geologists in the spacecraft also searched for information to analyze the cause of the hole.

"It is obvious that these traces of underground caves were formed under long-term water erosion conditions. Maybe there is water inside this cave entrance."

have water!

These two words made everyone present excited. As carbon-based organisms, human activities are inseparable from water. When we come to outer space and a strange planet, if we can find water, it will be heaven for humans. Hu starts.

As long as there is water, the rest is no problem.

Under the guidance of these people, the five members of the 12th team advanced little by little in the cave. The further they went inside, the more they saw what they saw inside, which stunned the geologists on the spacecraft.

"This location... this is not naturally formed. There are traces of artificial intervention here. It's on the right side, yes, yes, and 20 centimeters higher. Do you see that mark?"

"No, this is not our job. We have to call those archaeologists..."

Before these geologists had finished speaking, the twelfth team in the cave came to another place along the winding cave.

This is a space about more than 100 meters long and wide. In Blue Star, geologists have seen many such spaces during their karst exploration.

But the problem is that the underground caves in Blue Star rarely show traces of artificial excavation, because large space caves all appear deep underground.
