The successful test flight of "Dumbo" is of epoch-making significance for Qingquan Science and Technology to explore space, as mentioned above, every day can freely and quickly go back and forth to space, live on the ground, work and research in space, such a way of life has arrived.

And when the enlarged version of "Dumbo" and "Big Dumb Elephant" are actually manufactured, there will be no problems with large-mass space bases, such as space factories and space cities.

At present, Qingquan Technology has formed a complete space technology system, from the initial rockets and satellites, to the space station that only a few countries have that can stay in space for a long time, to the current space shuttle that can quickly travel between the ground and space, and then to the nuclear fusion power used for real spacecraft in the future.

It can be said that Qingquan Technology has truly mastered the technology and capital to explore space, and even if it is separated from the earth now, it can stay in space for a long time.

Controlled nuclear fusion technology can provide powerful power for large-mass, super-large spacecraft, space shuttles that can travel back and forth between space and the ground, can be used for combat and escort in space, and can also be used to explore various planets.

A very complete set of space technology has been researched by this group of scientists of Qingquan Technology, and what is missing now is an opportunity to do it boldly.

Of course, to build a massive spacecraft must be built in space, and it is simply not realistic to build it on the ground and then launch it, and this transportation cost alone is enough to bankrupt the company.

What's more, many of the super-large parts of the large-mass aircraft must be able to be manufactured at one time, rather than relying on parts to assemble, so the next step of Qingquan Technology is to build a space factory, and the space factory is naturally to find enough minerals to meet the construction and production needs of the space factory.

Naturally, the moon has entered the field of vision of the scientists of Qingquan Technology, and the moon is the closest and most massive celestial body to the earth!

The Moon is rich in mineral deposits, and it has been found that there are more reserves of rare metals on the Moon than on Earth.

There are three main types of rocks on the moon, the first is the lunar sea basalt, which is rich in iron and titanium; The second is plagioclase, which is rich in potassium, rare earths and phosphorus, and is mainly distributed in the lunar highlands; The third type is mainly breccia composed of 0.1~1 mm cuttings of rock chips. Moon rocks contain all the elements of the earth and about 60 kinds of minerals, of which 6 minerals are not found on the earth.

The moon is extremely rich in mineral resources, and the 17 most common elements on the earth abound on the moon. Taking iron as an example, the 5 centimeters of sand on the surface of the moon alone contains hundreds of millions of tons of iron, while the entire lunar surface has an average of 10 meters of sand.

Iron on the surface of the moon is not only abundant, but also easy to mine and smelt. It is reported that the iron on the moon is mainly iron oxide, as long as oxygen and iron are separated; In addition, scientists have developed ways to make cement and glass from lunar soil and rocks. On the surface of the moon, aluminum is also abundant.

The lunar soil is also rich in helium-3, and helium fusion using deuterium and helium-3 can be used as an energy source for nuclear power plants, which does not produce neutrons, is safe and pollution-free, and is an easily controlled nuclear fusion, which can not only be used in terrestrial nuclear power plants, but is also particularly suitable for astronautics.

It is reported that the content of helium-3 in lunar soil is estimated at 715,000 tons. For every tonne of helium-3 extracted from lunar soil, 6,300 tonnes of hydrogen, 70 tonnes of nitrogen and 1,600 tonnes of carbon are obtained.

Judging from the current analysis, due to the large reserves of helium-3 on the moon, it is undoubtedly a relief in the snow for the earth, which is relatively short of energy in the future, and many space powers have taken the acquisition of helium-3 as one of the important goals of developing the moon.

In the last century, the United States carried out many lunar landings in succession at the craziest time of the Cold War, of which 6 were successful, bringing back many valuable first-hand mineral specimens of the moon, and it was also the first time in human history to land on other planets except the earth, so that when the US president exchanged gifts with other countries, he shamelessly used small stones from the moon as gifts!

Such a resource-rich, very close to the precious mineral deposits, want to further develop into space Qingquan technology people can not miss, although the moon landing has not been carried out for the time being, but this does not mean that Qingquan technology does not have such technology, but it has not yet reached this step.

However, it is still necessary to launch some probes in the early stage, and first grasp the first-hand information of the moon, which is very useful for carrying out lunar landing activities, establishing lunar bases, and mining lunar resources in the future.

The huge Qingquan space station has been further expanded at this time, and there are hundreds of people traveling between the space station and the ground every day, and the space station maintains dozens of people at all times.

Now there are not only astronauts but also many scientific researchers staying in the space station, and Liu Qingquan also left the earth for the first time and came to space.

"It's so beautiful!" Liu Qingquan watched the beautiful scenery outside through the glass on the space station, the huge blue earth, which is the most precious resource in the universe.

In the dark starry sky, a little starlight passes through an unknown distance and is reflected in the field of vision; Looking at the direction of the moon again, it is even bigger and brighter, like the purest virgin, waiting for the development of Qingquan Science and Technology; More farther away, the master of the solar system, the most massive fireball that emits endless heat, is still burning quietly for 4.5 billion years, and it will continue to burn like this for 5.5 billion years, until finally it collapses internally because of insufficient mass and becomes a red giant and a white dwarf......

"Boss, the Jade Rabbit Probe is ready to be launched at any time!" accompanied Liu Qingquan to space together, as well as Jiang Zhipeng and Mo Qingming.

"Well, let's do it as planned!" Liu Qingquan came back to his senses and nodded.

The so-called "little jade rabbit" is the name code given to the first batch of lunar probes sent by Qingquan Science and Technology, the moon lives with fairies, the fairy is too lonely, send her a little rabbit!

An unmanned spacecraft slowly detached from the Qingquan space station, and the speed was very slow when it first broke away, of course, this is relative to the space station, and it began to accelerate slowly after identifying the direction, and the plasma engine using the latest technology can slowly accelerate its speed to more than Mach 100.

The average distance between the Moon and the Earth is about 384,000 kilometers, and the "Little Jade Rabbit" only needs less than 6 hours to reach the Moon, and half of the five hours are used to accelerate and decelerate, and at a speed of Mach 100, it only takes more than 3 hours to reach the Moon!

The "Little Jade Rabbit" carries more advanced quantum communication technology, which can transmit its real-time situation in real time, so that the space station can control and guide it.

After 6 hours of boredom, the "little jade rabbit" is about to reach the moon, at this time the gravitational pull of the moon has already exceeded the gravitational force of the earth, in the Qingquan space station, the screen of the control center is constantly playing the pictures transmitted by the moon rabbit in real time.

The "Little Jade Rabbit" has already begun to slow down, and by the time it reaches the lunar attachment, the speed has been reduced to the extent that it can be captured by the moon's gravity, otherwise it will approach the moon at a speed of Mach 100, and it will definitely fly over all of a sudden, and there will be no way to be captured by the moon's gravity to form a satellite.

After being captured by gravity, the Jade Rabbit first flew around the moon several times, collecting and collecting the most basic information on the lunar ground, and watching the moon up close, the moon is no longer as mysterious as it is in mythology, nor is it as white and bright as it looks from the earth and the space station.

In the picture sent back by the Jade Rabbit, the moon is dim, the surface is pitted, and the huge craters formed by the impact of meteorites seem to be the most ugly scars.

"This storm must have been formed by the impact of a super-large meteorite, look at its huge area of 5 million square kilometers, it is the size of 9 France, and it is estimated that the yield of the explosion is at least a million times that of the Hiroshima nuclear explosion!" Jiang Zhipeng pointed to the largest moon sea on the surface of the moon and said.

"Some people say that life on the earth can continue to this day, a large part of it is due to the fact that the moon has helped the earth block many huge meteorites from the universe, and the moon is equivalent to the outer shield of the earth, blocking meteorites from the universe, otherwise the earth's annihilation in the era of dinosaurs will have to experience at least so many more times!"

Mo Qingming, who was on the side, looked at the huge moon sea and said with a sigh, in fact, this moon sea is said to be the moon sea, but it is actually a very huge plain basin, because the age of the impact is too long, and many traces have been smoothed.

"The moon is not just a shield, it is the best gift from God to mankind, let's take a look at the results from the resource probe!" Yang Tianya said loudly that as an astrophysicist, he is more concerned about the resources of the moon.

The so-called resource detector refers to the use of multispectral remote sensing equipment to obtain multi-band electromagnetic wave information radiated or reflected by ground objects, and then send this information back to the control center.

Since the reflection of each object in different spectral frequency bands is different, after receiving the satellite signal, the control center will process and interpret this information according to the spectral characteristics of various substances it has mastered, so as to obtain detailed information such as the characteristics, distribution and status of various resources, so that people can avoid the hard work of running around and field surveys.

Everyone looked at the computer screen pointed by Yang Tianya, and the spectral information in the screen had been replaced with a division map of various mineral deposits.

"The moon is really a huge treasure trove, all kinds of mineral resources are extremely rich, and it is very conducive to mining, a gift from God!" (To be continued.) )
