Near the central waters of the Pacific Ocean, the Tang Empire is located on Kiribati's Christmas Island on the equatorial line, which has become the largest satellite launch center of the Tang Empire since the launch of the space race between the United States and the Soviet Union.

The main reason for choosing this place is based on safety and convenience considerations.

At this time, the Pacific Ocean has almost become the inner lake of the Tang Empire, and Kiribati is located in the absolute defense circle built by the Tang Empire, as an island, surrounded by the sea, outsiders cannot get close to the island, to ensure that the satellite launch secrets of the Tang Empire are not leaked.

In addition, launching satellites from low equatorial orbit can save a lot of costs, and can save considerable costs for the huge expenses of the huge space race, which can easily cost hundreds of billions of dollars. At the same time, the Tang Empire's goal is an alien spacecraft on the moon, and a space station in geostationary orbit needs to be established to transport it back, and the launch site for launching geostationary orbit satellites is located close to the earth's equator.

This is because the flight speed of the launched satellite is formed by the superposition of the speed of the launch vehicle and the rotational component of the earth's velocity, and in the case of a certain speed of the launch vehicle, the lower the latitude of the launch site, the greater the rotation speed of the earth, so that the orbital speed of the launched satellite will be greater. If a satellite is launched eastward from the equator, it can maximize the use of the Earth's rotational energy, which is essentially using the Earth's rotational force to increase the satellite's flight speed.

In addition, when launching a geostationary satellite from the equator or from a launch site close to the equator to the east, the flight orbit of the satellite can be in or close to the same plane as the final orbit, which can save a lot of energy required for the satellite to maneuver laterally to the geostationary orbit position. Greatly extend the operational life of the satellite.

Therefore, when the Tang Empire chose the launch site, it received Zhang Meng's advice and guidance. Choose to build directly near the equator in a low latitude area, which can not only borrow force, but also save effort.

For a satellite of the same weight, the propellant refueled by the Tang Empire launched on Christmas Island in Kiribati is 30% less propellant than that of Cape Canaveral in the United States, which is located at 30 degrees north latitude, and 52% less propellant than the Kapuskinyar Satellite Launch Center in the Soviet Union, which is located at 48.2 degrees north latitude at a higher latitude.

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

Meantime. Another advantage of the Tang Empire's choice to build a satellite launch center in Kiribati is that it can avoid rockets flying over inhabited areas, and in the event of an accident, it will fall into the sea, let alone be wrecked by other countries, so as to learn about the satellite technology of the Tang Empire.

Originally, the Tang Empire planned to complete the manned lunar landing program in ten years. But plans never keep up with change. In order to get the wreckage of the alien spacecraft as soon as possible, Zhang Meng secretly issued a holy decree, using the royal private treasury to urgently provide a budget of 50 billion Tang yuan, and at the same time complete the construction of a manned moon landing and a space station.

On March 3, 1958, the Tang Empire's first manned experiment in space was successful, and it was only one month after the last spacecraft was launched to carry a monkey into space. It can be seen how much importance the Tang Empire attaches to this matter, and it also shows the powerful scientific and technological strength and financial resources of the Tang Empire. In other words, the United States and the Soviet Union would never have been able to do it.

A year later, the Tiangong-1 of the Tang Empire was launched from the Christmas Island Satellite Launch Center in Kiribati, officially kicking off the construction 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 being stationed in space for a long time.

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

On February 7, 1965, the Tang Empire successfully developed the space shuttle, which replaced the nuclear warhead spacecraft, increased the number of astronauts in each liftoff, and realized the rapid replacement and replenishment of space station personnel, thus laying the foundation for accelerating the landing on the moon.

The Tang Empire has always been aiming to retrieve the alien spacecraft on the moon, so it doesn't matter how much it costs, due to the limitations of the material technology of the times, many experiments are facing huge risks, and many people sacrifice for this, but the Tang Empire has strictly sealed the news to the outside world, and the outside world does not know about it at all.

On the morning of July 6, 1969, a huge space shuttle was docked on the space station of the Tang Empire, the space shuttle was Chang'e-3, which used a small nuclear power reactor and could fly in space for 100 years, equivalent to the size of three Air Force One. It is equipped with two fuels, a rocket booster for travel to and from Earth, and a turbo aircraft engine for space flight, which is powered by nuclear reactor electricity.

With the commander's order, Chang'e-3 flew to the moon with five astronauts on board. This was a covert operation, and the Tang Empire did not make it public.

As Chang'e-3 arrived on the moon in four days and landed peacefully in the pre-set landing zone, the ground command center in Kiribati burst into thunderous applause.

Zhang Meng was very excited, he had completely ignored the excitement of the moon landing feat at the moment, and completely focused on the exploration of alien spacecraft.

Soon, the five astronauts took the lunar rover and quickly headed for the alien spacecraft crash site, all of them from the National Security Agency, and they already knew about the mission, so they were mentally prepared when they saw the crashed alien spacecraft.

However, they were still shocked by the alien spaceship, its material was completely undetectable, and a considerable part of the facilities inside were well preserved, all of which were unknown advanced equipment.

After several hours of exploration, the five astronauts discovered that the alien spacecraft was supposed to belong to some kind of communication spacecraft, presumably similar to Earth's reconnaissance aircraft.

In these few hours, the task of the five astronauts is to take pictures, from the global to the local, every detail is taken, tens of thousands of photos are taken, and the astronauts' hands are so tired that they are weak.

But they don't feel it at all, because they are in an extreme state of euphoria.

They were all super-physically strengthened soldiers, and soon began to transport small pieces of the ship's wreckage directly back to Chang'e-3, while large pieces of the wreckage were tied up with special steel ropes and hung on the spacecraft's specially prepared tail hook.

The series lasted a week, but the Chang'e-3 spacecraft was large enough to contain an automatic oxygen generator and enough food and water to keep it stockpiled, so that the five astronauts were able to successfully complete the first phase of the mission, loading about 70 small pieces of debris into the Chang'e-3 space shuttle, flying away from the moon and dragging a large piece of debris away.

The small wreckage can directly follow the Chang'e-3 spacecraft back to Earth, while the large wreckage requires special equipment to bring back to Earth: Chang'e-13, a huge nuclear warhead return capsule that has been waiting on the space station.

As Chang'e-3 flew back to the space station, the astronauts loaded large pieces of the debris into Chang'e-13's giant re-entry capsule and returned to Earth separately.

After the successful manned landing of the Tang Empire on the moon, a set of videos were released to show off the powerful capabilities of the Tang Empire to the world and achieve the feat of human landing on the moon.

At the same time, the Tang Empire also established Area 52, a closed island in the Pacific Ocean to store the wreckage of alien spacecraft for the study of Datang scientists.

As a series of wreckage of the alien spacecraft was transported back to Earth by Datang from the moon, layers of mystery were gradually unraveled, and Datang scientists were shocked like never before, the aliens have died, the skeletons are the same as humans, there is a supercomputer management, and the words used by various devices are oracle bones, and some of them are similar to the words used in the Qin Dynasty, which is shocking, indicating that China's mysterious Qin Dynasty has some connection with alien civilizations, and perhaps human beings originally came from outer space.

"Your Highness, this pendant was found from an alien skeleton, you can collect it if you like!"

Liu Yun, director of the Alien Research Institute of Area 52, gave Zhang Meng a beautiful robot-shaped pendant, and the moment Zhang Meng saw the robot pendant, a word popped up in his mind.

"How does it feel like a mech? What material is this made of? ”

Liu Yun shook his head and said: "For the time being, we can't know, we only know that the density of this pendant is comparable to the core of a star, and the size of a sesame seed weighs billions of tons, but this pendant weighs only 50 grams, which is very puzzling, maybe our scientific level is too low to solve the mystery." ”

Zhang Meng was curious, so he accepted it and prepared to pass it on from generation to generation as a family heirloom.

With all the wreckage of the alien spacecraft transported back to Earth, the Tang Empire immediately terminated the exploration of the moon, and at the same time launched a satellite to the solar system and the Milky Way, only sending radio waves in ancient Chinese, hoping to contact the alien civilization.

On the earth, although the scientists of the Tang Empire are temporarily unable to study through the wreckage of the alien spacecraft, they reprocess a small part of the inconsequential wreckage into some parts, among which the Tang Army's orbital kinetic energy cannon has not been able to switch materials instantly, and finally succeeded after replacing with alien materials, and the experiments have not been worn out tens of thousands of times, which means that the orbital kinetic energy cannon of the Tang Empire will enter the stage of actual combat deployment.

Similarly, scientists have made a detailed analysis of the electronic system and material structure on the alien spacecraft, although only a small point has been cracked, but it has also made the Tang Empire make a huge breakthrough in the field of electronic computers, especially in the material structure, and have successively developed a variety of powerful new materials. For example, the Tang Army's new generation of stealth supersonic cruise fighters, known as the fourth-generation Raptor fighter, cannot be detected by radar after using new materials, the engine is incomparably strong, and it maintains supersonic cruise for a long time, all because of new materials. Although the United States and the Soviet Union are also developing supersonic cruise fighters, it is a pity that the materials are not up to par, so that the engine life is very short and cannot realize military value.
