His words made the hearts of everyone in the hall surge, and they unconsciously dreamed that one day they could fly out of the earth and step into a new planet......

No matter what the planet is, it is hot, cold, irritable, calm, barren and rich.

Just thinking about this scene makes people feel excited.

Xu Shuwei looked at Xu Zhenglin and Zhang Ying on the screen, and said with a smile: "Your state still looks very good." ”。

Xu Zhenglin nodded and said with a smile: "Brother Xu, the temperature outside the moon is relatively high now, nearly 80 degrees Celsius, although the mecha has a thermal insulation layer and a cooling system, we can still clearly perceive that there are several places that will continue to heat up. ”

"Is it like this? Then it seems that the temperature system of the mecha needs more testing and modifications, so take two steps and take a look......"

Xu Shuwei and a group of scientific researchers began to communicate with Xu Zhenglin, and soon, a wide-angle anti-temperature camera on the heads of the two people entered the working state, and two large screens lit up, respectively, the wide-angle picture of the camera on the heads of the two people, and the incomparably desolate and gray lunar surface suddenly appeared in the hall.

When everyone looked at the content of the video screen, they all felt a burst of emotion.

Darkness and earth ash occupy the entire world on the screen, the upper layer is the pure dark cosmic space, the lower layer is the infinite barrenness of the earth-gray tone of the moon, the earth-gray without any life, and the severe polarization of high and low temperature difference between hot and cold, as if it is difficult for any life to survive and adapt to this land.

The screen began to shake as Xu Zhenglin and Zhang Ying walked out of the capsule, the multi-directional gravitational technology of the mecha made the two walk very steadily, the high temperature on the surface of the moon made the two of them not feel particularly comfortable, and the temperature of the thighs, arms and several major joints of the waist was slightly higher than in other places.

While talking to the surface world, the two began to walk slowly on the surface of the moon, and a special multi-functional small gravitational workbench slowly suspended behind the two, closely following the steps of the two.

For the first lunar exploration, they had a designated mission, which was to go to a crater not far from the landing site of Tianzhi-1.

After walking for a while, the two basically adapted to the gravitational pull of the moon, and at the same time, their bodies also consumed a lot of physical strength.

"Call Ayu, request to activate the multi-directional gravitational flight system." Xu Zhenglin said.

"Received, Lao Xu, the request has passed, the multi-directional gravitational flight system has been activated, pay attention to flight safety." Ayu's voice came into the ears of Xu Zhenglin and Zhang Ying.

"Okay, thank you, Ayu." The two of them thanked each other, and then began to raise their heads slightly, looking into the distance, and launched a take-off command for the mecha in their minds, and the brain waves were quickly accepted and processed by the SOR headband on the head, and the multidirectional gravitational system of the mecha was activated instantly, and the gravitational nodes of many parts of the body were activated.

The two mechs took off one after the other, flew into the sky, and then steadily began to fly towards the crater of spatial coordinates.

In the video screen, the field of view was suddenly expanded, and the rapidly expanding field of view made more moon images appear clearly on the big screen, and the large or small craters in the distance made everyone feel awe, which was just a very small force in the universe.

Soon, a target crater appeared in the field of vision, Xu Zhenglin and Zhang Ying flew straight after confirming it, the more they saw the complete outline of the crater, the more frightened the two became, this is a crater with a diameter of more than 7 kilometers, and this crater with a diameter of 7 kilometers is only a medium-sized crater in their training data!

But it was such a medium-sized crater that made the two of them tremble in body and soul!

It's too big!

The huge area that is deeply sunken looks like a super shock wave in an animated film and television work has exploded, and it looks like a shocking exaggeration.

Both of them were speechless from the shock of the massive crater.

In the Earth Laboratory, the same picture is projected onto the big screen, just like an incomparably real film and television work, and an indescribable mysterious will seems to descend into the laboratory through the screen, and the whole laboratory falls into a heavy solemnity.

"How much impact force does it take to create such a large crater?" Zhao Wanyu looked at the big screen intently and muttered.

After her quiet voice, the entire laboratory suddenly resounded with bursts of communication and discussion......

"Is it big?" Toni calmly watched the video.

"It's just a medium-sized crater, and on top of that there are large craters, super-large craters, giant craters, land-scale craters. Its diameter is more than 2,240 kilometers, its area is half the size of China, and its depth is more than 13,000 meters. ”

Toni's words made the surrounding people really fearful, half of the huge crater of China, if such a meteorite hits the earth, there is no doubt that a large area of life will be extinct, and naturally including human beings.

"Half of China! There are such large craters? I couldn't help but ask Sun Zhongyong, who was standing next to Toni.

Chen Mengchuan nodded and answered his question: "The south pole of the moon - Aitken Basin, this is a temporary name proposed by the International Astronomical Union, its official name has not been confirmed, but its size is indeed half the size of China, what Toni is talking about is a more conservative data value, there are many data that show that its maximum diameter is more than 2,500 kilometers, and from the depth alone, if it is compared to the highest point of the crater wall, then its height difference is more than 16,000 meters." ”

"On the edge of this crater, a huge circular bulge has formed, which some groups call the Leibniz Mountains. However, this name is not officially recognized by the International Astronomical Union. Brother Sun, we can send you up, and then you go over and officially discover and see this pothole, and then you can name it, you can name it Sun Zhongyong Pit! Chen Mengchuan said at the end, and he couldn't help laughing.

Several core members nearby laughed.

Sun Zhongyong rolled his eyes at Chen Mengchuan and said, "It's better to keep it for you to find and name, it's more appropriate to call Chen Mengchuan Pit." I'm just a little curious, how big a meteorite needs to be to smash such a large crater? It's hard to imagine ......"

Sun Zhongyong's words resonated with many people.

Toni's eyes trembled slightly, and he slowly spoke, "Do you want to know the cause?" There may be more answers soon, as long as the multi-armed crabs collect enough data parameters, and one day in the future, they may be able to really analyze it. ”
