This is the end of the launch process. Over the next three days, the Crimson Heart spacecraft will orbit the Earth about 70 times, and in the process, the Crimson Heart's orbit will become flatter and farther away, and the perigee will get closer and closer. Eventually, the Crimson Heart spacecraft will break free from the Earth's orbit at apogee and step into the vast expanse of space, where it will spend six to eight months.

In these three days, the five astronauts will be assisted by ground staff to carry out the final inspection and debugging of the Crimson Heart spacecraft before departure, after all, the Crimson Heart spacecraft is still in Earth orbit, if there is an accident, it can also be repaired by launching a rocket, if you step into the vast space and then have an accident, then there is really no way.

"The Crimson Heart spacecraft is powered by both conventional and ion engines." Wang Tang introduced to Zhao Huasheng, "When it is necessary to accelerate and decelerate in a short period of time, adjust the orbit and attitude, the spacecraft uses conventional engines, and during the journey to the sun, the spacecraft does not need to make too many orbit adjustments, it uses ion engines. ”

Conventional engines are powered by the posterior injection of high-temperature gases from the combustion of chemical fuels, which is powerful enough to exert a very large amount of force on the spacecraft in a short period of time, but also consumes a lot of fuel. Ion engines, on the other hand, are different. It ionizes the propulsion working fluid, then uses a strong electric field to accelerate the ions, and ejects them from the rear to gain propulsion.

The ion engine also obtains acceleration through thrust reversing, but its efficiency in the use of working fluid is more than 15 times that of conventional engines. This means that a lot of fuel can be saved on the ship, and the ion engine can propel the ship farther and faster if it is long enough.

But the ion engine has a fatal drawback, and that is that the thrust is too small. Just like the ion engine on the Crimson Heart spacecraft, at full power, it can only increase the speed of the spacecraft by 0.5 centimeters per second. However, the accumulation of a small amount, 0.5 centimeters per second, can accelerate the spacecraft by more than 400 meters per second in a day, 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 the space flight, the spacecraft will also use the gravitational pull of Venus to accelerate, and after more than two months of flight, it will enter an orbit only 30 million kilometers above the surface of the sun, and then orbit the sun for two to four months, collecting detailed data from the sun to determine what is going on in the reverse fusion layer."

In the solar system, the closest planet to the Sun is Mercury, but even though Mercury is nearly 60 million kilometers away from the Sun, Crimson Heart is only 30 million kilometers away, almost half the distance of Mercury.

"Actually, personally, I don't have much confidence in relying on the technological power of our humans to change the sun." "I only hope that the data collected by the Crimson Heart spacecraft and the nearly thirty solar exploration satellites that will be launched in the future can provide you with some clues and inspiration for solving the mystery. ”

Zhao Huasheng nodded silently.

"No one has said these things explicitly, but I know that all those in the know, including the Führer, think so. We've had breakthroughs during this time, and we've even known about the existence of the antifusion layer, but the more we know, the more desperate we become. Wang Tang's hand began to tremble slightly, "That's the reverse fusion layer that wraps the entire sun...... How can we humans have the strength to break them? ”

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

"I'm going to Equator City." Zhao Huasheng said, "I already have some vague ideas at the moment, and believe me, I can figure out what this is going on soon." ”

"Good, good." Wang Tang nodded, "Aren't you going to the City of Life?" There is still order and peace there. Equatorial City is a bit of a mess right now. ”

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

"Well, I wish you a nice journey." Wang Tang patted Zhao Huasheng's shoulder.

"I wish the Crimson Heart all the best. Good bye. ”

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

After all, it's tropical, and even though solar radiation levels drop by 15 percent, it's still warm. It's just that I don't know how long this warmth will last.

In addition to the natural landscape, Zhao Huasheng also saw many man-made objects. There are long lines of heavy goods vehicles, each of which means at least fifty tons of supplies. And just by glancing from the sky, Zhao Huasheng saw that at least tens of thousands of trucks were densely packed there. And that's just one road in a small area. In other places, how many trucks are still delivering goods to Equator City on other roads, Zhao Huasheng does not know.

Zhao Huasheng also saw a railway. Almost every three minutes, a train of more than 1,000 meters long whizzed by, laden with coal, oil, salt, grain, cement, steel and other supplies, and a large number of trains passed on its opposite lane, but those trains were empty, and there was no cargo on them.

The amount of goods that this railway transports to Equateur City every day alone is already a terrifying astronomical amount. According to Monzo, the number of railways leading to Equator City is now as high as more than 300. And that's just the freight railway, and it doesn't take into account passenger corridors.

Above the sea are countless freighters. Those goods ** have a flat and wide class A, and the top of class A is densely packed with containers piled together, and countless huge ships are distributed on the sea, and from a high altitude, almost the entire sea surface is covered. In addition to roads, railways and ships, the skies are also busy.

The height of the helicopter is only a few hundred meters, and there are jet planes shuttling in the air thousands of meters and tens of thousands of meters above it, and the huge engine roar can even be heard by Zhao Huasheng who is riding in the helicopter.

Before he came to Equator City, Zhao Huasheng felt the busy atmosphere coming to his face. The enormous executive power of human civilization is on full display here, and it is even so large that it can make people feel awe.

Zhao Huasheng knows that at least tens of millions of people are busy on this front. Train drivers, coach drivers, sailors, airplane drivers, docks, airports, cargo stations, dispatchers, stevedores, etc., these people together form a lifeline, transporting huge amounts of blood from all over the world to Equateur City, so that the people in Equateur City can live.

"According to statistics, the daily delivery of various materials to Equateur City has reached 1.57 billion tons, and this does not include the local output of Equateur City's 40 million square kilometers of land." "In order to expand the routes, they even dismantled the railroad tracks that were laid elsewhere and installed them here, and they even converted the river cargo ships and put them into ocean transportation." Almost all trucks in the world are requisitioned and placed at the disposal of the government. Human civilization has used all its power to save the wealth we have created and scattered around the world before the earth is frozen. ”

Zhao Huasheng nodded, still not speaking. The helicopter moved on.

The closer you get to Equatorial City, the more busy it becomes. Zhao Huasheng has already seen countless construction sites that are almost contiguous underground, endless greenhouses used to grow food, and a busy and crowded flow of people.

"In order to speed up the construction schedule, we have adopted a modular construction method, where large quantities of construction materials are produced at the factory, and after being transported to the construction site, they only need to be processed and put together like building blocks. Workers worked day and night, and it only took half a month to build a 50-story building. A 50-storey building can provide livelihood support for at least 5,000 people. Of course, comfort is not to be talked about. In these last days, it would be nice to be alive, and the government does not have the energy and resources to think about comfort. ”

"The monetary system has been reformed, and the previous currency has been converted into contribution points according to a very low ratio, and a worker can get about 30 contribution points a day of work, which can maintain the minimum living security of five people, and there is also a limit on the ration system, that is, the amount of materials that each person can buy every day is limited, even if a person has a large number of contribution points, he can't buy too many materials."

"The entertainment and leisure industry is severely restricted, the production of luxury goods is banned, and the production of alcoholic beverages is restricted......"

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

The helicopter eventually flew over the tall buildings and busy construction sites, and finally landed in a relatively clean and spacious neighborhood.

"This is Area 337 in District C of Equator City, you will live here temporarily, if you have any other requirements, I am always available to accommodate you." Monjo said.
