A genius remembers "Love to go ÷ small? Speak → Net" in one second to provide you with wonderful novel reading.
Liu Qingquan looked at all this with a smile. A small moon's resources surprised everyone, not to mention the wider interstellar universe. Very precious and rare diamonds and gold on the earth, maybe there is such a thing in the universe. All the planets are made of gold, or they are all made of diamonds.
Compared with that barren resource on the earth, the universe is the real treasure house. The real value of the earth is that she can conceive life, and life is the most precious thing in the universe!
The Xiaoyutu spacecraft has successively launched a number of small satellites, among which are geological satellites for detecting and mapping the lunar landforms, resource detection satellites for detecting resources, and navigation positioning satellites for relay communications and establishing small communication navigation positioning ... ...
With the launch of these satellites, the Qingquan Space Station and the ground control center began to receive more and more clear and detailed moon data. The new quantum communication technology developed by the Level 2 scientist Zhou Jingband Regiment can transfer all information without delay. With traditional electromagnetic wave communication technology, there will be at least a second delay in the electromagnetic wave's return to the moon.
The moon is smaller than the earth, with a diameter of 3476 kilometers, which is about 3/11 of the diameter of the earth; the surface area of ​​the moon is about 79x10? Square kilometers, and the surface area of ​​the earth is 1/14, which is slightly smaller than that of Asia; its volume It is 199x10 cubic kilometers, which is 1/49 of the earth. In other words, the earth can hold 49 moons.
The mass of the moon is 349x10 ?? kg, 1/81 of the earth; the average density of matter is 34 grams per cubic centimeter, which is equivalent to only 3/5 of the density of the earth; the gravity on the moon is only 1/6 of the earth, that is, A 6-kilogram thing weighs only 1 kilogram on the moon limit. People walk on the moon and their bodies look relaxed.
"Launch the unmanned landing probe!" With Jiang Zhipeng's minus, a probe on the Yutu spacecraft 380,000 kilometers away ejected a probe directly to the surface of the moon.
Because the mass of the moon is too small and the gravity is not enough to attract the atmosphere, the moon has no atmosphere. The landing probe flew to the surface of the moon at a 45-degree oblique angle. When the moon was about to reach the moon, the anti-gravity engine inside the probe began to work Let the probe slowly and gently land on the moon's surface.
Unlike the jet landing method adopted by the United States on the moon landing, Qingquan Technology with anti-gravity technology, anti-gravity technology landing is more secure and stable.
The place where the landing probe landed is in a flat basin on the moon. This kind of place is called the sea of ​​the moon. It is formed by the meteorite hitting the surface of the moon. There are countless large and small moon seas on the moon. Countless bullets from the universe.
Of course, even if 99% of the meteorite hits the earth, it will burn most of the mass due to friction with the earth's thick atmosphere. The rest is irrelevant to the earth, but it forms the 22 largest moon seas of the moon. If the meteorite hits the earth, a huge disaster will occur!
The landing probe opened a door, and a lunar exploration vehicle drove out slowly. The camera and communicator on the head turned around, feeling stunned.
A sloping plate extending from the landing probe slowly landed on the moon's surface. First, it turned around to find the direction, and then looked into space. A azure planet was continuously photographed.
"Oh ~~ oh ~" The Qingquan Space Station and the ground control center saw the beautiful view of the Earth from an alien planet for the first time, and everyone couldn't help cheering! Looking at the earth from the moon, bright and beautiful!
After the exploration vehicle transmitted the beautiful photos of the earth, and quickly put into intense work, it slowly searched for something, stayed idly, and slowly walked on the surface of the moon. From time to time, it used its own shovel to shovel some dirt to the prepared place. Among the planned boxes.
When encountering stones of interest, some small ones will be collected, and when encountering some big guys, you can't help but also go up and knock! If it weren't for the moon's lack of air, and sound propagation needed a medium, otherwise it would have been a banging sound. Any stone on the moon would contain very rich iron.
The exploration vehicle beats and digs the dirt all the way, like a naughty and curious child. In fact, this is all controlled by the Qingquan Science and Technology Space Station and the ground control center.
Every place that stays is based on the results of resource exploration satellites in space. It is not really aimless, digging and moving stones at will.
It is important to know that the detection vehicle can be limited in its installation. Of course, compared to the detectors launched in other countries, the detection vehicle of Qingquan Technology is very large. It is smaller than ordinary cars, but it can be installed. Things are still very limited.
A few hours later, the boxes inside the detection vehicle were finally full, and at this time it finally reluctantly walked back, following the traces of the car passing in front, and driving back to the lunar device all the way.
The rover returned to the lander, opened its huge belly, and the standard boxes filled with various dirt and stones were taken out by the robotic arm, covered with a lid to store, and then the rover returned to the moon. Be left here, go to sleep, and wait until Qingquan Technology launches the lunar lander next time, it will wake it up again!
And when Qingquan Technology really builds a large-scale base on the moon and mines, it will take it back to the earth and place it in the space museum. It is a historic little jade rabbit, a Chinese Valuable record left on the moon for the first time.
The "Boom ~" landing probe left a small jade rabbit, slowly taking off with precious lunar soil and ore specimens, because the moon ’s gravitational force is only 1/6 of that of the earth. The speed is much lower, it only needs 8 km / s to get rid of the gravity of the moon, and it needs 9 km / s to get rid of the gravity of the earth.
The landing probe slowly faced the "Little Jade Rabbit" lunar exploration spacecraft, and was then slowly dragged into the spacecraft. After it was fixed, the spacecraft began to return to the sea. This time its mission was completed and it successfully won the first place. A variety of lunar data in one hand, and also obtained massive lunar soil and rock specimens.
Six hours later, the lunar exploration spacecraft finally returned to the Qingquan Space Station. The robotic arm prepared earlier captured it gently, the spacecraft opened automatically, and the standard boxes inside were taken out.
Soon, several "Dumbo" space shuttles flew back to the earth with several boxes, and a few minutes later, the space shuttle landed on the ground control center of the future base. The specimens are researched and tested for various data.
Through these soil and rock specimens collected from the moon, scientists can study and infer a lot of things. Based on the amount of tungsten-182 isotope in the rock, you can measure the relative very accurate age of the rock, so that the moon ’s The age is about 4.6 billion years.
This data is not only consistent with the current theory of the formation of the moon, but also supports the theory of the formation time of the earth. It will help to study the history of the formation of the earth. According to the theory of large collision, the moon and the earth are formed at the same time. It is expected that the age of the earth will be calculated.
Of course, this is still very helpful for studying the history of the earth and the moon, but Qingquan Technology now pays more attention to the specific situation of the moon resources.
By analyzing the collected soil and rock specimens, you can know the content of each element and the method of element composition, so that you can determine whether it has mining value, what mining method should be used, and so on.
"How?" Liu Qingquan, who had returned to the ground, was also impatiently concerned about the collected specimens. The amount of moon resources is related to the implementation of future space programs.
"It's very rich. All the elements on the earth are all present, and they are very concentrated and easy to mine. Many scarce minerals on the earth, such as rare earths, are very rich on the moon. In the future, this rare metal will be worthless!"
The scientist responsible for analyzing soil and rock samples passed an analysis data to Liu Qingquan and said with emotion.
Liu Qingquan took the data report and looked at it carefully. The lunar specimen collected this time is actually very small compared to the huge mass and area of ​​the moon. The area where the probe collected the specimen is very small, but even so, the collected There are dozens of elements in the specimens.
Among them, the content of iron element that Liu Qingquan values ​​most is very high. Among the stones collected from Yuehai Basalt, the iron content is as high as 80% or more, which is basically the richest iron ore. Compared with The best iron ore on earth is better and better!
In addition, the composition of iron ore on the moon is mainly iron oxide, which is very conducive to refining. You only need to separate iron and oxygen to get a lot of steel and rich oxygen. This is important for the construction of large-scale spacecraft and space factories. Space City is of great help.
Liu Qingquan was very happy, and after reading each item of data, he had to sigh that the moon is really a gift from Earth to the earth. Liu Qingquan, who is familiar with the development of the civilization of the universe, rarely has the earth like his own star next to his home star. There will be a satellite with such rich resources. Such an extremely rich satellite is too precious for a civilization that has just stepped out of its parent star and started cosmic exploration!
You must know that compared to the universe, the distance between the earth and the moon is too close and completely insignificant. Not only does it help the earth to block meteorites and meteors from the universe, but it is also a treasure star, a resource-rich precious planet, gift, universe Gift!
