In terms of space launch systems, Xinhua will naturally not repeat the mistake of developing the "space shuttle" in Lijianguo, but will choose a better aerospace aircraft.

The space shuttle, also known as the space shuttle or space shuttle, is a manned spacecraft that takes off vertically and lands horizontally, which is launched into space with a rocket engine as the power, and the plane glides and lands in the atmosphere.

The Space Shuttle is capable of orbiting and can travel between the Earth's surface and low-Earth orbit, making it a partially reusable spacecraft.

Aerospace aircraft is the abbreviation of aerospace aircraft, it can fly in the atmosphere, but also can fly in space, is a highly integrated aviation technology and aerospace technology aircraft, like an airplane from the ground horizontally, return like an airplane horizontal landing, become a free shuttle between heaven and earth.

The technical difficulty of realizing the space plane is greater than that of the space shuttle, mainly because of the combination and switching of three power plants, high-strength, high-temperature resistant materials and the control system with artificial intelligence.

Aerospace aircraft are characterized by high speed, high maneuverability, high stealth, and long range, possessing many advantages.

First, in terms of cost, the space plane only consumes liquid hydrogen mixed fuel, which is only one-tenth of the space shuttle, or even one-tenth of it!

The space shuttle, on the other hand, was sent into the sky on a large rocket every time, and it had to carry a fuel tank that was even larger than itself.

With each flight, the launch vehicle causes a lot of pollution and forms countless discards. The fuel tank will also be thrown in near-Earth space, which will not only cause a huge waste of costs, but also create space junk.

Aerospace aircraft can be reused many times, reducing launch costs, improving reliability, and shortening the launch cycle. Achieve the goal of fast, maneuverable, reliable and inexpensive access to space.

Second. Aerospace aircraft are not affected by the climate. It can provide the means to quickly launch satellites in large quantities at any time, and can send up to more than 10 large satellites and dozens or hundreds of small satellites into space, significantly improving the competitiveness of commercial launches.

Third, aerospace aircraft can be equipped with reconnaissance equipment and serve as reconnaissance, surveillance, and early warning platforms to obtain enemy intelligence in the process of orbiting in space like military satellites. It is more flexible, has stronger comprehensive reconnaissance capabilities, and has better real-time performance.

Fourth, it can be equipped with high-energy lasers, small missiles, and other weapons systems as a platform for launching space weapons, so that it can be transformed into an aerospace fighter or bomber, and use its maneuverability to shuttle through space, so that it can track and jam the space equipment of the enemy country or launch attacks.

Fifth, aerospace aircraft can be used as fast long-distance transport aircraft. From a regular airport, you can quickly reach anywhere in the world in one to two hours. Respond quickly to regional conflicts on a global scale.

Liberia has developed five types of space shuttles: Space Shuttle Columbia, Space Shuttle Challenger, Space Shuttle Discovery, Space Shuttle Atlantis and Space Shuttle Endeavour, of which Space Shuttle Columbia has a carrying capacity of 36 tons.

The space shuttle Buran, developed by the Soviet Union, was capable of carrying 30 tons of cargo.

Xinhua's latest Long March 5 carrier rocket has a carrying capacity of 13 tons for geosynchronous transfer orbit and 23 tons for low-earth orbit.

The large "Hope" aerospace aircraft jointly developed by Xinhua and Hualong is 78 meters long, has a wingspan of 39 meters, a height of 17 meters, a weight of 250 tons, and a carrying capacity of more than 20 percent of its own weight.

This means that it only takes more than 80 liftoffs and less than a year to build the "Tiangong" space station.

The reason why Xinhua China revised its small space station plan and dared to build the "Tiangong" space station of more than 4,000 tons was because of the astonishing carrying capacity of the new aerospace aircraft.

Spacecraft capable of traveling to and from the moon or even any planet in the solar system are already being developed.

The space plans drawn up by the three parties also include the construction of two space power stations, a space city, a moon base and a Mars base.

When the cost of putting supplies into orbit drops to a certain distance, space solar power plants become a reality, and the technical capabilities represented by the Hope space plane are key to achieving this goal.

Space power stations are very large, the power station will be made up of many square, round or bowl-shaped solar panels, the total area will reach several square kilometers, the solar cells are made very thin, very light, and weigh only 150 grams per square meter.

The space power station operates in a geostationary orbit 36,000 kilometers above the equator, and the satellites in orbit are in line with the Earth's rotation period, i.e. 1 rotation per day. One can see it in the night sky like a dazzling star.

The intensity of sunlight in geostationary orbit is 14 times that on the ground. Except during solar eclipses, it can generate electricity continuously 24 hours a day, night, season, and weather, so the utilization rate of solar energy in space is more than 10 times that of the ground utilization.

Space power stations can replace thermal power plants that pollute the environment, provide inexhaustible clean energy for mankind, and make a significant contribution to the earth's environmental problems.

Solar power generation is the use of semiconductors to directly convert light energy into electrical energy, the current technology can only convert 15-30% of solar energy into electrical energy, the new nano solar cell technology that the energy room has come up with an astonishing conversion efficiency of 70%.

The power station converts the collected solar energy into electricity, which is then transmitted directly to the power grid in all corners of the earth using microwave transmission antennas.

Microwaves for power transmission are a type of light waves, which belong to the wavelength range used in satellite broadcasting, microwave ovens, and mobile phones.

With current technology, if 100 watts of direct current were converted into microwaves, 30% of the energy would be lost. The technology provided by the Oriental Group has increased the efficiency of wireless energy conversion and transmission to 85%, and the utilization rate is much higher than that of wire transmission.

Both technologies are revolutionary innovations that have the power to transform the entire energy sector.

In 2018, Xinhuaguo and Hualong Guo will each build a space power station with a power generation capacity of more than 2 billion watts, which can transmit electricity to relatively remote areas to meet the needs of 600,000 households.

The satellites and solar panels of the space power station are maintained by smart phones, and it also has a laser defense system to protect it from damage caused by small meteors and space junk.

The moon base jointly planned by the three parties will explore, exploit, realize, and refine the mineral resources on the moon, and the Eastern Bloc is even more prepared to use this base to build a large-scale "Oriental Star" space city.

Moon rocks are rich in aluminum, iron, titanium, silicon, oxygen and other elements, and 95% of the building materials of the space city can be found from the moon.

On top of that, the gravitational pull of the Moon is only one-sixth of that of the Earth, and an object needs to reach 11,200 m/s to leave the Earth, while it only takes 2,400 m/s to leave the Moon, and it takes 95% less energy to send the same heavy material into space than from the Earth.

Scientists estimate that as long as 150 people are sent to the moon, more than 1 million tons of ore can be mined every year. The ore is heated, smelted, and processed into various building materials and components such as aluminum and glass using solar energy, and then assembled in orbit to build a space city.

In terms of design, the "Oriental Star" space city is a bit like the annular space city in the science fiction movie "Elysium", which will use rotation to generate artificial gravity to help future astronauts live and work better in space.

This circular rotation design is not a random fantasy of the film director, but has a rigorous scientific basis, as early as the sixties and seventies some scientists proposed.

Of course, the "Oriental Star" space city is not as large as the space city in the movie, and it does not have the same good living environment as in it - everyone lives in large villas, ecological oases everywhere, rivers, lakes and so on.

After completion, the "Eastern Star" space city covers an area of about 7 square kilometers and will live with about 50,000 people, mainly used for space tourism, as well as as as a starting point for space exploration activities such as landing on other planets and mining asteroid resources.
