Since the construction of Chanjuan City, the rich mineral resources on the moon have been gradually developed.

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, as well as rich rare metal deposits, and the moon has more reserves than the entire earth.

The lunar highlands where Chanjuan City is located are rich in plagioclase rock, rich in potassium, rare earths and phosphorus.

There are also a large number of basalts rich in iron and titanium in the Moon Sea within 200 kilometers of it, and there are countless iron oxides that are easily smelted in the sandy soil of the lunar surface, which played a vital role in the construction process of Chanjuan City.

After four years of development, the number of people in Chanjuan City has exceeded the design of 00,000.

In the latest count, there are more than 70,000 people, and thousands of people travel between the Earth and the Moon every day.

Jiang Wenbin and Cheng Qianqian's Tian-109 flight is the latest type of Tianke-3 spacecraft, which sails automatically throughout the whole process, and the time to reach the moon is 10 and a half hours, which is 2 and a half hours faster than the Chanjuan 00001 module four years ago.

In the past few years, thanks to the wave of space development, the aerospace spacecraft industry has developed tremendously, and the speed of upgrading has been rapid.

Nowadays, any NASA employee exudes the light of money all over his body.

There are 109 flights a day, designed to carry 1,500 passengers, with a square shape and an orange-yellow body, like a piece of soap magnified countless times.

It has four floors inside, and Jiang Wenbin and Cheng Qianqian sit in the secret cabin on the top floor.

Chanjuan City is still a major strategic project, and there are many secret areas, so space spacecraft are often designed with cabins for high-level personnel.

They can enter and exit through specialized passages, avoiding everyone's sight.

Cheng Qianqian slept in a spacious and comfortable seat, and when she woke up, she happened to look down on Chanjuan City.

Since the moon has no atmosphere and no pollution, she can clearly see countless huge blocks of various colors connected together according to some kind of rules, undulating and densely covering a large area, complex and strangely beautiful, like the remains of ancient gods.

"That's Chanjuan City, the first space city that our country spent four years building!" Jiang Wenbin couldn't suppress his excitement and pride, this is the city he built with his own hands!

"Four years ago, when I came here in cabin 00001, it was still a barren moon land, but now it has become a human home!" Jiang Wenbin's eyes were full of light, and his voice was like a dream.

As a Chinese, Cheng Qianqian also feels honored.

As the spacecraft approached the moon, she noticed a large patch of green in the distance, and asked curiously:

"What's that? Could it be growing vegetables in a greenhouse?"

"Hahaha!" Jiang Wenbin laughed happily:

"How could it be. The temperature of the lunar surface under the direct sunlight is as high as 150 degrees, and no food can survive, which is vacuum photoelectric algae. A city the size of Chanjuan City would be a disaster if it suddenly lost energy in space. In order to ensure energy security, we use four layers of energy safeguards. ”

"First of all, the day-by-day No. 1 provides long-distance power transmission through relay satellites, and Chanjuan City is the highest priority for electricity consumption; secondly, we have opened up a vacuum photoelectric algae power station on the surface of the moon to supply power to Chanjuan City through underground wired lines; third, there are a large number of energy crystal batteries under Chanjuan City as a backup power supply, which is enough for the entire Chanjuan City to be fully used for 10 days. Finally, there is a backup nuclear power plant in the Moon Sea, but it is not ignited. ”

Jiang Wenbin is one of the few people in charge of energy, and he deals with these people every day.

Of course, he only said the part that could be made public.

In fact, there are two sets of spare energy crystal battery packs, and the other group is in a confidential position, and only he and a few people know the location.

This confidential information will not be exposed to unrelated persons.

Cheng Qianqian said admiringly:

"There are countless people behind any big project, and such a spectacular space city must have paid a huge price for it. ”

When asked about the price, Jiang Wenbin's eyes were a little gloomy.

Chanjuan City is a great initiative that has never been done before, and it has also brought great sacrifices.

At the beginning, the 12-person team of the 00001 cabin of Chanjuan City was the first batch of pioneers in the entire Chanjuan City, and they suffered huge sacrifices.

Today, only nine people are still alive, and the rest have died in various accidents.

Jiang Wenbin's eyes were full of sadness, pointing to the east of Chanjuan City, and said astringently:

"See, that monument. ”

Monument?

Cheng Qianqian looked carefully, because the distance was still far away, she could only see what seemed to be a pure black metal tablet, faintly reflecting bright light in the sunlight.

"This monument seems to be a bit high?" Cheng Qianqian saw something unusual:

"Is this the space monument that is permanently suspended in mid-air?"

Jiang Wenbin was full of emotion:

"Yes, this is the Huaguo Space Memorial, commemorating all the heroes who died to conquer space. In order to build Chanjuan City, the 'Expedition-1' Space Industrial Park, and the 'Blinds' recent power station, more than 500 heroes have died in various accidents, and their heroic souls will always be there to inspire those who come after. ”

The black monument seemed to be as heavy as Mount Tai in Cheng Qianqian's eyes, it was a monument watered by 500 pioneers with their lives, and she said softly:

"Going to the universe is the inevitable path for the development of human civilization, and I believe that their sacrifices will never be wasted. ”

Flight 109 approached the moon at a very fast speed, and Chanjuan City gradually changed from a palm-sized to a behemoth in the field of vision of the two.

Soon after, the spacecraft's announcements rang out simultaneously in the passengers' DTs and in the cabin.

"Passengers, the day 109 flight is about to arrive at the end of the day Chanjuan City Station, the spacecraft may be a little bumpy when landing, please sit in your own seats and wear seat belts"

Chanjuan City Aerospace Spacecraft Station is so close to the Space Monument that every passenger who comes to the moon can see it for the first time.

The area of the space spacecraft station is amazingly large, with hundreds of space spacecraft of various types lined up in four rows, covering a large area.

After the landing of the 109th flight, the two will not stay on the moon, and will directly transfer to the long-distance spacecraft to the 'Hundred Leaf Umbrella', and together with more than 100 engineers and experts, they will go to the inner orbit of Mercury.

Since the entire voyage will take place in 2 days, 17 hours and 59 minutes, each passenger will have a dedicated suite.

"It is worthy of being called the crossroads of the solar system!" Cheng Qianqian repaired for a short time, and then leaned on the thick glass and looked out the window.

In just ten minutes, a number of spacecraft took off and headed for their respective destinations, which was very busy.

Today, Chanjuan City has become the hub of human space transportation, connecting the earth, the Shutter Umbrella Power Station and the Expedition No. 1 Space Industrial Park, and all the space spacecraft will transit from the Aerospace Spacecraft Station in Chanjuan City.

Soon after, a tremor was heard, and the spacecraft took off.

Cheng Qianqian stared at the blue planet in the sky.

Against the black cosmic background, it is so brilliant and colorful.

Her eyes became confused, and she muttered:

"Goodbye, Earth! Goodbye, my"

Her voice was softened, and she couldn't make out what the last words were.
