The launch process comes to an end here. Next, the Red Heart spacecraft will orbit the earth for about seventy cycles in three days. During this process, the orbit of the Red Heart spacecraft will become flatter and flatter, the orbit will become farther and farther, and the perimeter will become closer and closer. In the end, the Red Heart spacecraft will break free from the Earth's orbit at the apogee, and then enter the vast space, spending its long six to eight months.

During these three days, five astronauts will conduct the last detection and debugging of the Red Heart spacecraft before departure with the assistance of ground staff. After all, the Red Heart spacecraft is still in orbit on the earth. If there is any accident, it can also be repaired by launching rockets. If there is another accident in the vast space, there is really nothing we can do.

"The Red Heart spacecraft uses two driving methods: conventional engine and ion engine as the power source." Wang Tang introduced to Zhao Huasheng, "When it is necessary to accelerate and decelerate and adjust orbit and posture in a short time, the spacecraft uses conventional engines. During the journey to the sun, the spacecraft does not need to make too many orbital adjustments, so it uses ion engines."

Conventional engines use the backward injection of high-temperature gas generated by chemical fuel combustion as the source of power. It has strong power and can exert a huge amount of power on the spacecraft in a short period of time, but it consumes a lot of fuel. The ionic engine is different. It first ionizes the working fluid, and then uses a strong electric field to accelerate the ions, allowing them to eject from the rear to obtain driving force.

Ion engines also obtain acceleration through reverse thrust, but their efficiency in utilization of working fluid is more than fifteen times that of conventional engines. This means that a large amount of fuel can be saved on the spacecraft. With the same fuel, the ionic engine can push the spacecraft to fly further, and if it takes a long enough time, the speed will be faster.

But the ion engine has a fatal disadvantage, that is, its thrust is too small. Just like the ion engine equipped on the Red Heart spacecraft, under full power operation, it can only increase the speed of the spacecraft by 0.5 cm per second. However, it accumulates a little to more than 400 meters per second in a day. Therefore, 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 accelerate with the help of Venus' gravity. After more than two months of flight, it will enter an orbit only 30 million kilometers away from the surface of the sun, and then orbit around the sun for two to four months, collecting detailed data on the sun to determine what the inverse fusion layer is going on."

In the solar system, the closest planet to the sun is Mercury, but even if Mercury and the Sun are close to 60 million kilometers, the distance of Red Heart is only 30 million kilometers, which is almost half the distance of Mercury.

"Actually, for me personally, I have no confidence in relying on our human technological power to change the sun." Wang Tang Youyou said, "I only hope that the data collected by the Red Heart spacecraft and the nearly thirty solar exploration satellites that will be launched in the future can provide some clues and inspiration for your puzzles."

Zhao Huasheng nodded silently.

"No one said these words clearly, but I know that all insiders, including the head of state, have thought this way. We did make breakthroughs during this period, and we even knew the existence of the anti-fusion layer, but the more we know, the more we are desperate." Wang Tang's hand began to tremble slightly, "That is the anti-fusion layer that wraps the entire sun... How can we humans have the power to break them?"

"I'm sorry, I'm a little out of my composure." Wang Tang said, "What are you going to do next?"

"I'm going to the Equator city." Zhao Huasheng said, "I already have some vague ideas at this moment. Believe me, I can figure out what's going on soon."

"Very good, very good." Wang Tang nodded, "Don't you go to the City of Life? It's still order and stability there. Equator City is now a little confused."

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

"Okay, I wish you a good journey." Wang Tang patted Zhao Huasheng on the shoulder.

"I wish the Red Heart a smooth journey. Goodbye."

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

After all, this place is tropical. Even if the solar radiation level has dropped by 15%, it still maintains warmth. But I don’t know how long this warmth can last.

In addition to the natural landscape, Zhao Huasheng also saw many man-made objects. There are heavy trucks arranged in long rows, each heavy truck means at least fifty tons of supplies. Just by glances from the sky, Zhao Huasheng saw at least tens of thousands of trucks there. This is just a road in a small area. In other places, there are still many trucks transporting goods to the Equator City on other highways, Zhao Huasheng doesn't know.

Zhao Huasheng also saw a railway. On that railway, a train of more than 1,000 meters whistled past almost every three minutes. It was loaded with coal, oil, salt, grain, cement, steel and other materials. There were also a large number of trains passing by in its opposite lane, but the trains were empty and there was no cargo on it.

The cargo transported to the Equator city every day by this railway alone is already a terrifying astronomical figure. According to Meng Zhuo, the number of railways leading to the Equator city has reached more than 300. This is just a freight railway, and the passenger channel is not included.

There are countless freighters on the sea route. Most of those freighters have a flat and wide Class A. There are densely packed containers on the Class A. Countless giant ships are distributed on the sea surface. From a high altitude, they almost cover the entire sea surface. In addition to roads, railways and ships, the sky is also extremely busy.

The helicopter is only a few hundred meters high, and there are jets shuttles all the time at a height of thousands of meters above it. The roar of the huge engine can even be heard by Zhao Huasheng, who is riding in the helicopter.

Before he arrived at Equator City, Zhao Huasheng felt the busy atmosphere coming to his face. The huge execution ability of human civilization is fully revealed here, and 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, aircraft pilots, docks, airports, cargo stations, dispatchers, loaders and unloaders, etc., all formed a lifeline, transporting huge amounts of blood from all over the world to Equator City, so that people in Equator City could live.

"According to statistics, the various types of materials transported to Equator City have reached 1.57 billion tons recently, which does not include the local output of 40 million square kilometers of land in Equator City." Meng Zhuo said, "In order to expand the transportation route, they even directly demolished the railway tracks laid in other places and installed them here. They even transformed the river cargo ships and put them into ocean transportation. Almost all trucks in the world have been recruited and controlled by the government. In order to save the wealth we created before the earth was frozen, human civilization has used all its power."

Zhao Huasheng nodded, but still said nothing. The helicopter continued to move forward.

The closer you get to the Equator City, the more busy the atmosphere becomes. Zhao Huasheng has seen countless construction sites appear underground, almost continuous greenhouses for growing grain, and busy and crowded crowded people.

"In order to speed up the construction progress, we adopted a modular construction method. A large number of construction materials will be produced when they leave the factory. After being transported to the construction site, they only need to go through simple processing and then build them up like building blocks. The 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 not a question. In this end of the world, it is good to survive, and the government does not have the energy and resources to consider comfort."

"The currency system has been reformed. The previous currency was converted into contribution points at a very low proportion. A worker could obtain about thirty contribution points a day. These contribution points can maintain the minimum living security of five people, and there is also the limitation of the rationing system. That is, the supplies that each person can purchase every day are limited. Even if a person has a large amount of contribution points, he cannot buy too much materials."

"The entertainment and leisure industry is strictly restricted, luxury goods are banned, alcoholic beverages are banned..."

Meng Zhuo kept whispering to Zhao Huasheng about the situation in Equator City at this moment, while Zhao Huasheng listened quietly.

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