Near the central waters of the Pacific Ocean, the Tang Empire is located on Christmas Island, Kiribati, an equatorial territory. Since the space race between the Tang, the United States and the Soviet Union, it has become the largest satellite launch center of the Tang Empire.

The reason why I chose here is mainly based on safety and convenience considerations.

At this time, the Pacific Ocean had almost become the inner lake of the Tang Empire. Kiribati was located within the absolute defense circle built by the Tang Empire. As an island, surrounded by sea, outsiders could not get close to the island to ensure that the satellite launch secrets of the Tang Empire were not leaked.

In addition, launching satellites from low-orbit equatorial orbit can save a lot of money, which can save considerable expenses for huge space races that cost hundreds of billions of yuan. At the same time, the Tang Empire aims to use alien spacecraft on the moon. If you want to transport it back, you need to establish a space station with stationary orbit. Building the launch site of the geostationary orbit satellite in a position close to the earth's equator can achieve twice the result with half the effort.

This is because the flight speed of the launched satellite is formed by the superposition of the rotational components of the launch vehicle's speed and the rotational component of the earth's speed. When the speed of the launch vehicle is certain, the lower the latitude of the launch field, the greater the rotational speed of the earth, so that the orbital speed of the launched satellite can be made. If a satellite is launched from the equator eastward, the rotational energy of the earth can be used to maximize the use of the earth's rotational force, which is essentially using the rotational force of the earth to increase the flight speed of the satellite.

In addition, when launching geostationary orbit satellites from the equator or launching grounds near the equator, the satellite's flight orbit can be in or near the same plane as the final orbit, which can save a lot of energy required for the satellite to maneuver horizontally to the geostationary orbit position, greatly extending the satellite's operation life.

Therefore, when choosing a launch site, the Tang Empire received advice and guidance from Zhang Meng. Choose a low-latitude area and build it directly near the equator, which can not only leverage and save labor.

For a satellite of the same weight, the propellant added by the Tang Empire on Christmas Island in Kiribati was saved by 30% of the propellant from the launch of Cape Canaveral in the United States at 30 degrees north latitude, and 52% of the propellant from the launch center of Capskiny satellite at 48.2 degrees north latitude of the Soviet Union at a higher dimensional latitude.

This advantage and gap cannot be seen on one or two small satellites, but when the Tang, the United States and the Soviet Union launched a large-scale space race, more than a dozen to dozens of satellites were launched every year, and the cost and launch of each satellite were huge. This advantage and gap immediately emerged.

At the same time, the Tang Empire chose to establish a satellite launch center in Kiribati, and another advantage is that it can prevent rockets from flying over inhabited areas. If something happens, it will fall into the sea, and will not be debrised by other countries, thereby learning about the satellite technology of the Tang Empire.

Originally, the Tang Empire planned to complete the manned moon landing plan in ten years, but the plan could never keep up with the changes. The United States and the Soviet Union rushed to catch up, which made the Tang Empire feel extremely pressured. In order to get the wreckage of the alien spacecraft as soon as possible, Zhang Meng secretly issued an imperial edict, using the royal private vault to urgently provide a 50 billion Tang yuan budget, and at the same time complete the manned moon landing and the construction of the space station.

On March 3, 1958, the Tang Empire successfully carried a manned space experiment for the first time, only one month after the last launch of the spacecraft carrying a monkey into space. It can be seen how much attention the Tang Empire attached to this matter, and it also showed the strong technological and financial resources of the Tang Empire. If it were the United States and the Soviet Union, it would never be able to do it.

A year later, the Kiribati Christmas Island Satellite Launch Center was launched at the Tang Empire Tiangong-1, officially kicking off the establishment of the space station.

In less than six years, the Tang Empire launched 263 rockets one after another, and finally completed the space station project, realizing the great feat of the Tang people stationed in space for a long time.

Of course, there have been more than a dozen launch failures in the meantime, resulting in the sacrifice of six astronauts, but the Tang Empire still completed the space station project under pressure.

On February 7, 1965, the Tang Empire successfully developed a space shuttle, replacing a nuclear warhead spacecraft, increasing the number of astronauts each time it took off, and quickly replacing the space station personnel stationed, thus laying the foundation for accelerating the landing on the moon.

The Tang Empire has always aimed at retrieving the moon's alien spacecraft, so it doesn't matter how much the price it pays. Due to the limitations of the material technology of the times, many experiments face huge risks, and many people sacrificed for it. However, the Tang Empire strictly blocked the news from the outside world, and the outside world was not aware of it.

On the morning of July 6, 1969, a huge space shuttle was docked on the Datang Empire Space Station. This space shuttle is Chang'e 3. It uses a small nuclear-powered reactor and can fly in space for 100 years, equivalent to the size of three Air Force Ones. It is equipped with two fuels, one is a rocket booster used to travel to and from the earth, and the other is a vortex aero engine used for space flight, which uses the power supply and power of the nuclear reactor.

With the commander's order, Chang'e 3 flew to the moon with five astronauts. This was a secret operation and the Tang Empire was not disclosed.

As Chang'e 3 took four days to arrive on the moon, after landing safely in the preset landing area, thunderous applause sounded at the ground command center of Kiribati.

Zhang Meng was very excited. At this moment, he had completely ignored the excitement of the feat of landing on the moon and focused his energy on the detection of alien spacecraft.

Soon, five astronauts took a lunar rover to quickly advance towards the crash point of the alien spacecraft. They all came from the National Security Agency and had already known about the mission, so they were mentally prepared when they saw the crashed alien spacecraft.

However, they were still shocked by the alien spacecraft. Its materials could not be detected at all. A considerable number of facilities inside were well preserved, all of which were unknown advanced equipment.

After several hours of exploration, five astronauts discovered that this alien spacecraft should belong to some kind of communication spacecraft, and it is speculated that it is probably similar to the reconnaissance aircraft category.

In the past few hours, the five astronauts' mission was to take photos. From the overall situation to the local area, every detail was taken. After taking tens of thousands of photos, the astronauts' hands were so tired that they were soft.

But they couldn't feel it at all because they were in an extreme excitement.

They were all soldiers who had been strengthened by super physical strength and soon began to transport small pieces of spacecraft wreckage back to Chang'e 3 directly. Large pieces of wreckage were tied up with special steel ropes and hung on the tail hook specially prepared by the spacecraft.

This series of work lasted for a week. Fortunately, the Chang'e 3 spacecraft was large enough, with automatic oxygen generation devices, and reserved enough food and water. Therefore, the five astronauts were able to successfully complete the first phase of the mission, loading about 70 small wrecks into the Chang'e 3 space shuttle, flying away from the moon, and taking a large wreck away by dragging.

The small wreckage can directly follow the Chang'e-3 spacecraft to return to Earth, while the large wreckage requires special equipment to be brought back to Earth. This is Chang'e-13, a huge nuclear warhead return capsule, which has been waiting at the space station.

As Chang'e-3 flew back to the space station, the astronauts loaded large pieces of wreckage into the huge return capsule of Chang'e-13 and then returned to Earth respectively.

After the Tang Empire successfully landed on the moon by manned landing, a set of videos was released to the public to show off the powerful capabilities of the Tang Empire to the world and realize the feat of human beings landing on the moon.

At the same time, the Tang Empire also established 52 zones, which specializes in storing the remains of alien spacecraft on a closed island in the Pacific for research by scientists from the Tang Dynasty.

As a series of wreckages of the alien spacecraft were transported from the moon to the earth by the Tang Dynasty, layers of mysterious veils gradually unraveled, and the Tang Dynasty scientists were shocked like never before. Aliens were dead, and the bones were the same as humans. There was a supercomputer to manage. The words used by various devices were actually oracle bones, and some of them were similar to those used by the Qin Dynasty. This was shocking, indicating that China's mysterious Qin Dynasty had some connection with alien civilizations. Perhaps humans originally came from outer space.

"Your Highness, this pendant was found in the bones of aliens. If you like it, you can collect it!"

Liu Yun, director of the Alien Research Institute in District 52, gave Zhang Meng an exquisite robot-shaped pendant. When Zhang Meng saw the robot pendant, a word appeared in his mind.

"How does it feel like a mecha? What material is it made of?"

Liu Yun shook his head and said, "We don't know yet. We only know that the density of this pendant is comparable to that of the core of a star. The size of a sesame seed is billions of tons, but this pendant weighs only 50 grams, which is very puzzling. Perhaps our scientific level is too low to unravel the mystery."

Zhang Meng was curious, so he accepted it and prepared to pass it on as a family treasure for generations.

As all the wreckage of alien spacecraft was transported back to Earth, the Tang Empire immediately terminated the exploration of the moon and launched a satellite to the solar system and the Milky Way, only emitting radio waves outward in ancient Chinese, hoping to contact the alien civilization.

On Earth, although scientists of the Tang Empire were unable to study the wreckage of alien spacecraft for the time being, they reprocessed a small part of the irrelevant wreckage into some parts. Among them, the switching materials of the Tang army's orbital kinetic energy guns were not in a short time. After replacing them with alien materials, they finally succeeded. The experiment was tens of thousands of times without wear. This means that the orbital kinetic energy guns of the Tang Empire will enter the actual deployment stage.
