The live broadcast made the world realize 3D printing technology. Many companies are very interested in 3D printing technology, now decided to set up 3D printing R & D department. At the same time, many companies call SpaceX company to know the specific content of 3D printing technology, hoping to use 3D printing technology to print some products!

    On the moon, 3D printer robots start printing new things again.

    After watching for a while, they were shocked.

    "Am I right? It seems to be printing mining robots?"

    "It should be, but this mining robot should be a simple version!"

    "Is SpaceX going to mine on the moon? There are abundant mineral resources on the moon, especially a large number of helium-3 nuclear energy raw materials, which can be used for the earth''s nuclear reactor, but helium-3 is very rare on the earth! As far as I know, helium fusion using deuterium and helium-3 can be used as energy for nuclear power plants. This kind of fusion does not produce neutrons, is safe and pollution-free, and is easy to control. It can be used not only for ground nuclear power plants, but also for space navigation! Zeus now uses nuclear fission. If we dig up a lot of helium-3, we may use nuclear fusion as energy in the future, so as to improve the speed and energy reserves of the spacecraft! "

    At this time, an expert said on the TV station: "there are three main types of rocks on the surface of the moon. The first type is Yuehai basalt, which is rich in iron and titanium and fills the vast depression of Yuehai; The second type is norite, also known as non Yuehai basalt, which is formed by partial melting of plagioclase rich rocks with high contents of K, REE and P; The third kind of moon rock is called aluminous clinopyroxene, which is mainly composed of plagioclase and pyroxene. It is the product of lunar magma separation more than 4 billion years ago. The surface of the lunar plateau is mainly composed of aluminum rich anorthosite.

    According to the current exploration results, the mineral resources on the moon are extremely rich, and the reserves of rare metals are more than those on the earth. The 17 most common elements on earth can be found everywhere on the moon. Take iron as an example. There are hundreds of millions of tons of iron in the 5 cm thick sandy soil on the surface of the moon, while there are 10 meters of sandy soil on the surface of the moon. The surface of the moon is not only rich in iron, but also easy to be mined and smelted. It is reported that iron on the moon is mainly iron oxide. As long as oxygen and iron are separated, not only iron can be obtained, but also oxygen can be obtained; In addition, scientists have developed ways to use lunar soil and rock to make cement and glass, enabling houses to be built on the moon. It is understood that adding graphene to Corning''s glass can effectively prevent radiation. Imagine a city shrouded by graphene glass, how sci-fi it will be! One day, we should be able to live in such a city

    Moon.

    Zeus, Captain Guan Xing, was in touch with the lunar module''s leader by radio“ Blake, in addition to establishing a base for mining, the most important task of our mission is to explore whether there is water on the moon! In the 1990s, two independent departments, Clementine and lunar explorer, revealed that the water on the moon may exist on the surface of the moon as ice, especially at the two poles of the moon. Just now, the Zeus probe remotely sensed that there seems to be water resources in the polar crater of the moon! You immediately take the lunar module to the polar regions of the moon for investigation! "

    "Yes, Captain!"

    The rest of the people also heard the captain''s order, black immediately arranged for four people to take the anti lunar module to go to the polar region of the moon, the other two people stay in place, command the robot to carry out the mining work! If there is water on the surface of the moon, it is very likely that there is water in the rocks of the moon, which may be found in the process of mining!

    After a while, the lunar module began to fly, first to the south pole of the moon. After more than an hour, the lunar module arrived at the south pole of the moon. If there is water here, or water can be extracted from it, then it is the best choice to build a permanent residential base here!

    After the spacecraft landed, the cabin door was opened, and 12 small detectors flew out first, and then explored the surrounding area. Black and two astronauts with equipment, began to install drilling equipment in the lunar polar, will be tens of meters under the ground rocks are extracted for testing!

    At this time, the live broadcast of Zeus'' lunar landing is over, and then there will be a three-month lunar exploration time. Many things are trivial. If the live broadcast continues, the mystery of the lunar landing will be gone! However, when the live broadcast ended, people immediately complained! We are looking forward to seeing whether there is water in the polar regions of the moon. How can we stop the live broadcast at this critical moment?!

    "SpaceX company, I want to watch the live broadcast, I want to see if they can find water!"

    Netizens are furious and complain to the official website of SpaceX!

    SpaceX company immediately said, "previously, Zeus landed on the moon for live broadcast, using a high-power signal transmitter, which required a lot of energy to send high-definition video to the space station, and then the space station will send the video to the earth. After three months of lunar exploration, Zeus will return to earth, so in order to save energy, SpaceX decided to interrupt the live broadcast. Please understand. However, please rest assured that you will be informed of any major discoveries made by Zeus on the moon in time! "

    After listening to this explanation, people have nothing to say. Zeus has to save energy to return to the earth. If Zeus is forced to live broadcast, it will lead to insufficient energy for Zeus to return to the earth. That''s a big sin!

    Netizens are still very kind, have said: "the original is so, well, live interrupt it, Zeus safe return to earth is the most important!"

    Although the live broadcast of Zeus was interrupted, people''s curiosity about the moon became more and more intense, and there was a heated discussion about whether the moon had water.

    "There is no air, no life, no water on the moon!"

    "Water can''t be buried underground. How do you know there is no water?"

    “……”

    Everyone has their own opinions, and no one can persuade anyone!

    In addition, many people see the success of SpaceX landing on the moon, and space travel has become a hot topic for a while, attracting countless people''s expectation and expectation!

    "It''s only two days to go to the moon from the earth, and space travel has become a reality!"

    "Yes, I can go to the moon in two days. It''s not long at all! If the price is within my range, I am willing to go! It''s enough to go to the moon in one''s lifetime

    “……”
