Earth Era

The launch process comes to an end here. Next, the Crimson Heart spacecraft will orbit the earth about seventy times in three days. During this process, the orbit of the Crimson Heart spacecraft will become more and more flat, and the orbital apogee will become more and more The farther you go, the closer the perigee is. In the end, the Crimson Heart spacecraft will break free from the Earth's orbit at apogee, and step into the vast space to spend a long period of six to eight months.

During these three days, the five astronauts will conduct the final inspection and debugging of the Crimson Heart spacecraft before departure with the assistance of the ground staff. After all, the Crimson Heart spacecraft is still there. Earth orbit, if there is an accident, it can be repaired by launching a rocket. If there is an accident in the vast space, there is really no way.

"The Crimson Heart spacecraft uses conventional engines and ion engines as its power source." Wang Tang introduced to Zhao Huasheng, "When acceleration and deceleration and adjustment of orbit and attitude are required in a short period of time, the spacecraft uses conventional engines. During the journey to the sun, the spacecraft does not need to make too many orbital adjustments, and uses the ion engine."

The conventional engine uses the high-temperature gas produced by the combustion of chemical fuel as its power source. It is powerful and can exert a huge force on the spacecraft in a short time, but it also consumes a lot of fuel. The ion engine is different. It first ionizes the propellant, and then uses a strong electric field to accelerate the ions, so that they are ejected from the rear to obtain propulsion.

The ion engine also obtains acceleration through reverse thrust, but its utilization efficiency of working fluid is more than fifteen times that of conventional engines. This means that a lot of fuel can be saved on the spacecraft. With the same fuel, the ion engine can push the spacecraft to fly farther, and if the time is long enough, the speed will be faster.

But the ion engine has a fatal disadvantage, that is, the thrust is too small. Just like the ion engine equipped on the Crimson Heart spacecraft, under the condition of full power operation, it can only increase the speed of the spacecraft by 0.5 centimeters per second. But it adds up to more than 0.5 centimeters per second, and one day can accelerate the spacecraft by more than 400 meters per second, so in comparison, the ion engine is still an efficient way of propulsion.

Zhao Huasheng knew all these things, so after hearing Wang Tang's words, Zhao Huasheng just nodded.

"During space flight, the spacecraft will also be accelerated by the gravity of Venus. After more than two months of flight, it will enter an orbit only 30 million kilometers from the surface of the sun, and then orbit the sun for two to four months. Months to collect detailed data on the sun to determine what is going on in the reverse fusion layer."

In the solar system, the planet closest to the sun is Mercury, but even if the distance between Mercury and the sun is nearly 60 million kilometers, the distance of the Crimson Heart is only 30 million kilometers, which is almost half of the distance of Mercury.

"Actually, personally, I have no confidence in relying on the technological power of our human beings to change the sun." Wang Tang said faintly, "I only hope that the Crimson Heart spacecraft and the nearly thirty suns that will be launched in the future. The data collected by the probe satellites can provide some clues and inspiration for your puzzle solving."

Zhao Huasheng nodded silently.

"No one has said these words explicitly, but I know that all the insiders, including the head of state, have such thoughts. We have indeed made breakthroughs during this period of time, and even we already know the existence of the reverse fusion layer. , but the more we know, the more desperate we are." Wang Tang's hands began to tremble slightly, "That is the reverse fusion layer that wraps the entire sun... How can we humans have the power to break them?"

"I'm sorry, I've lost my way." Wang Tang said, "What are you going to do next?"

"I'm going to Equator City." Zhao Huasheng said, "I already have some vague thoughts at this moment. Believe me, I will soon be able to figure out what is going on."

"Very good, very good." Wang Tang nodded, "Aren't you going to the City of Life? Order and stability are still maintained there. Equator City is a little chaotic now."

"No, let's go to Equator City first." Zhao Huasheng said.

"Alright then, I wish you a smooth journey." Wang Tang patted Zhao Huasheng on the shoulder.

"I also wish the Crimson Heart a smooth journey. Goodbye."

After leaving the launch base, Zhao Huasheng took a plane to Equator City. During the journey all the way south, the surface that Zhao Huasheng saw gradually changed from pale and withered yellow to other colors, and green began to appear on the surface.

After all, it is tropical here, and even though the level of solar radiation has dropped by 15 percent, it is still warm here. It's just that I don't know how long this warmth will last.

In addition to natural landscapes, Zhao Huasheng also saw many man-made objects. There are long queues of heavy goods vehicles, each of which means at least fifty tons of supplies. And just a glance from the sky, Zhao Huasheng saw at least tens of thousands of trucks there. This is just a highway in a small area. In other places, Zhao Huasheng did not know how many trucks on other roads were delivering goods to Equator City.

Zhao Huasheng also saw a railway. On that railway, almost every three minutes, a train with a length of more than 1,000 meters whizzes past, which is full of coal, oil, salt, grain, cement, steel and other materials. There were also a lot of trains passing by in the lanes, but those trains were all empty with no cargo on them.

The daily shipment of this railway to Equator City alone is already a terrifying astronomical amount. According to Mengzhuo, the number of railways leading to Equator City has reached more than 300 at this moment. This is only freight rail, and does not count passenger lanes.

On the sea road are countless freighters. Most of those freighters have a flat and wide Class A. Above the Class A are densely packed containers. Numerous giant ships are scattered on the sea, and when viewed from a high altitude, it almost covers the entire sea. In addition to roads, railways and ships, the sky is also very busy.

The height of the helicopter is only a few hundred meters, but at the altitude of several thousand meters and tens of thousands of meters, there are jet planes shuttled all the time. The huge roar of the engine can even be heard by Zhao Huasheng in the helicopter. arrive.

Before he came to Equator City, Zhao Huasheng felt the busy atmosphere coming to his face. The huge executive power of human civilization is fully revealed here, it is even so huge that it will make people feel awe.

Zhao Huasheng knew that at least tens of millions of people were busy on this front. Train drivers, bus drivers, sailors, plane pilots, docks, airports, cargo terminals, dispatchers, loading and unloading personnel, etc., these people together constitute a lifeline, transporting huge amounts of blood from all over the world to Equatorial City. , so that people in Equator City can live.

"According to statistics, the amount of various materials delivered to Equator City recently has reached 1.57 billion tons every day, and this does not include the local output of the 40 million square kilometers of land in Equator City." Meng Zhuo said, "For the sake of To expand the transportation route, they even dismantled the railway tracks laid in other places and installed them here. They even remodeled the river cargo ships and put them into ocean transportation. Almost all the trucks in the world are requisitioned and placed under the control of the government. . Human civilization has used all its might to save the wealth we have created scattered around the world before the land freezes."

Zhao Huasheng nodded, but still did not speak. The helicopter moved on.

The closer you get to Equator City, the more busy it is. Zhao Huasheng has seen countless construction sites appearing underground that are almost connected to each other~www.NovelMTL.com~, saw the continuous greenhouses used to grow food, and saw the busy and crowded flow of people.

"In order to speed up the construction progress, we have adopted a modular construction method, a large number of construction materials will be produced when they leave the factory, and after they are delivered to the construction site, they only need to undergo simple processing and then put them together like a The building blocks can be put together. Workers work day and night, and it only takes half a month to build a fifty-story building. A fifty-story building can provide living security for at least 5,000 people. Of course, Comfort is out of the question. In this apocalypse, it would be nice to live, and the government doesn’t have the energy and resources to think about comfort.”

"The currency system has been reformed, and the previous currency has been converted into contribution points at a very low rate. A worker can get about 30 contribution points for a day's work. These contribution points can maintain the minimum living guarantee for five people, and The limitation of the rationing system means that there is a limited amount of materials that each person can buy every day, and even if a person has a large number of contribution points, he cannot buy too many materials."

"The entertainment and leisure industries are severely restricted, the production of luxury goods is prohibited, and the production of alcoholic beverages is restricted..."

Meng Zhuo kept explaining the situation of Equator City to Zhao Huasheng in a low voice, while Zhao Huasheng listened quietly.

The helicopter finally passed over the high-rise buildings and busy construction sites, and finally landed in a relatively clean and wider block.

"This is No. 337, Area C, Equator City. You will live here temporarily. If you have any other requirements, I can meet you at any time." Meng Zhuo said.
