The spacecraft landed on the surface of the moon smoothly, and Yin Tian walked down in a spacesuit full of science and technology.

This suit of spacesuit is blue and white. It is far from bulky as the spacesuit on earth. At least, Yin Tian feels that wearing it will not affect his actions.

What's more, to Yin Tian's surprise, the spacesuit is equipped with two individual weapons as standard, an EMP rifle and a high-frequency concussion knife.

These two weapons are absolutely more advanced than Earth Technology by a few blocks, but I don't know how powerful they are.

After getting off the spaceship, Yin Tian felt his body was light. He took a step and the whole person jumped up. It took him a while to get used to the gravity here.

The gravity of the moon is only one sixth of the earth's, and Yin Tian's 180 Jin weight here is only equivalent to 30 jin. However, his strength has not been reduced. Therefore, if he uses the same force to walk, the whole man will surely fly.

The surface of the moon is grayish brown, covered with weathered debris. Because there is no atmosphere, the sun's ultraviolet rays can completely shine on the surface of the moon, which also leads to no life on the moon.

Ahead, a tube of metal objects was abandoned there, which should be the Apollo 11 living quarters.

When Apollo 11 returned to earth, all that was not needed was discarded, leaving only the cockpit and propulsion system.

Nearly 50 years later, the living cabin has been dilapidated. The paint on the surface has disappeared completely. It looks like it has been rusty.

Yin Tian walked into the interior of the living cabin and found that the appearance inside was very similar to that in science fiction movies.

After walking around, Yin Tian saw anything valuable and went out.

"Strange, why can't we find it?" Yin Tian murmured to himself.

He could not help but feel surprised that he could not find the American flag.

At that time, the Americans held a picture of the moon flag to show off for half a century, for fear that the world would not know that they were the first to land on the moon.

After searching again, Yin Tian did not find anything. At this time, he found a metal pole inserted in the ground not far away. He went over to have a look and thought that it was probably the flagpole of the American flag.

With a laugh of self mockery, Yin Tian suddenly felt that he was a bit silly. A piece of cloth was made into a national flag. On this moon without atmosphere protection, he was afraid that it had already turned into dust.

With a faint sigh, Yin Tian said that his dream of the American flag was doomed to be impossible.

After another round of walking, Yin Tian felt that the moon was meaningless. He had planned to return, but suddenly he wanted to visit the back of the moon.

But he did not think that this temporary decision almost cost him his life.

……

Because of the tidal locking between the moon and the earth, the moon almost always faces the earth on one side, and the vast majority of the other side cannot be seen on the earth.

The characteristics of the two hemispheres of the moon are significantly different. There are many huge moon seas on the front; on the other side, there are dense craters, only a small number, about 2.5% of the area is covered by the sea, compared with 31.2% of the front sea.

In the history of human spaceflight, the exploration of the back of the moon has never stopped. However, except for some photos released by the United States and the Soviet Union in the 20th century, no pictures have been sent out in recent years, and Yin Tian has always been puzzled by this.

Fifty years ago, human beings had landed on the moon, but in the next 50 years, there was no plan to land on the moon again. This is a huge doubt.

It is also said that Hawking, one of the greatest scientists in human history, once warned people not to go to the moon, but he did not explain why.

What, in the end, has led to human beings' taboo on the moon, which has been yearning for countless years, and even dare not go to the moon again? Yin Tian decided to solve the puzzle himself.

Xiaohui took off again and began to fly to the back of the moon.

Just five minutes later, the back of the moon completely appeared in Yin Tian's eyes.

Compared with the top of the moon, the back of the moon is much uglier. In the dark light, Yin Tian only saw a huge crater, and there was no other discovery.

"Little gray, lower the altitude."

"Yes, master."

"Xiaohui" slowly landed, and the altitude was reduced to about 500 meters. At this height, Yin Tian could see everything on the ground through the spacecraft's detection camera.

The spacecraft was flying around the back of the moon. Yin Tian's eyes never left the three-dimensional screen in front of him. He always felt that the surface of the moon was not as simple as he saw.

But as time went by, Yin Tian never found anything. Slowly, he finally gave up. Maybe there was no secret on the back of the moon. He just thought about it.But just as a cow was about to leave, the picture on the screen made his eyes suddenly open!

"What is this?"

I saw a crystal blue light appeared on the screen, if you don't pay attention to it, you can't see it.

"Little gray, enlarge the screen!"

"Yes, master."

The picture on the screen zoomed in quickly, and the blue light was clearly in front of him.

"This is Glass? "

His eyes were full of surprise. Yin Tian's blue light was actually a blue glass under the ruins. Around the blue glass was a box of metal structures. In this way, the blue glass looked like the Party style glass of a car.

"Xiaohui, land quickly."

Yin Tian's tone was excited. He knew that no matter what the blue glass was, it could not be formed naturally.

In other words, he found traces of civilization on the back of the moon!

Yin Tian put on his spacesuit again and went outside. He decided to see what the blue glass was.

The dark back of the moon is very quiet. Yin Tian can't hear any sound except his own footsteps. His steps are very light, and every step will float 5 meters.

Soon, the blue glass has completely appeared in front of Yin Tian's eyes. He guessed that the blue glass is indeed a potential position similar to the cockpit of a spaceship.

Whoa!

Yin Tian suddenly lifted the stones above the cockpit for more than ten meters, then pulled the cockpit and began to exert force to see that it could be pulled out from under the gravel.

Click, click, click

The cockpit was "rattled" by Yin tianla, but it never moved. Yin Tian had to give up at last.

Fortunately, the cockpit door is open. Yin Tian can go in there and have a look.
