"Please note that we are about to arrive at Jinghai Base. After taking off from the Dhahran Base, after about ten hours, we changed to the moon space shuttle, we finally approached the finish line." The beautiful voice of the flight attendant sounded in the space shuttle.

Now, it is 2020. After more than 30 years of development, the world has undergone earth-shaking changes.

Under the threat of aliens, the world is highly economically integrated. While the economy is developing significantly, it also has more funds and has invested in the aerospace field.

Due to geographical advantages, Dhahran replaced Baikonur and became the largest space launch base. Baikonur has mainly become a space measurement and control center. At the same time, the lunar base has become one of the largest bases!

Jinghai Base covers an area of ​​more than 100 square kilometers, and it has become a city on the moon!

The early pioneers built a rough base. After that, with the increasing number of tools to land on the moon, various lunar factories were established on the surface of the moon, and large-scale underground bases were built! And in the entire lunar base, there were tens of thousands of people working!

Moreover, the moon base is also open to the public. Rich businessmen on Earth, even married couples, will make travel to the moon as one of their projects.

First, take the commercial Shenlong space shuttle from the Dhahran base and arrive at the space station in space.

The Shenlong aerospace plane was improved on the basis of the Goddess of Dawn, and it used a large number of repeatable components to reduce the launch cost. In particular, it used certain special elements mined from the moon as components of the aerospace plane, making the operating cost of this aerospace plane very low. It can be said that buying a ticket like this is about the same price as taking a high-speed rail in later generations.

This kind of space plane just transports them to space stations. The space station code-named International is the fourth-generation space station launched by the Soviet Union and also undertakes private tourism projects.

On the International Space Station, four or five lunar space shuttles docked at any time. This type of space shuttle uses a nuclear power system to travel to and from the moon and space stations.

These are exactly two different solutions. Aerospace shuttles use variable cycle engines that can fly in and out of the atmosphere, while lunar space shuttles use nuclear power, so there is no need to worry about polluting the atmosphere.

After decades of development, these technologies have been quite mature and are almost 100% reliable!

At the same time, experiencing the feeling of weightlessness and taking space travel is already the favorite project on Earth.

"The moon is really too desolate." At this time, looking outside the glass of the space shuttle, the bumpy surface of the moon, the girl said dissatisfiedly among the young couple who came to travel.

"Yes, it's quite desolate to look at the surface, but when you get inside the base, it's lively." The boy next to him said: "On the moon, you can jump several meters high, and we can also wear lunar suits and walk around outside, especially the spacecraft of the Courage, which is about to take off, and we can just take a look at the launch of the Courage."

Courage!

Over the years, after continuous investment in the field of space, the Soviet space technology has also been constantly improving. The most important of these is the technology required for interstellar flight!

If you want to fly interstellar, it requires a lot of cross-age technologies to emerge. Unfortunately, after so many years, you still have not made a fundamental breakthrough.

For example, the space-time distortion technology was first proposed by Miguel Alcubire, a physicist at Cardiff University in Wales, England in 1994. It uses "singular matter" with negative mass and negative pressure that has not been discovered. It can distort space-time, so that the space in the space quickly approaches the space in front, while the space behind is constantly expanding. The spacecraft is like being in an expanding "bending bubble", which can fly faster than the speed of light and will not violate the principles of relativity.

However, this technology can only be an ideal. To distort time and space, it requires huge energy, and it will even be greater than the entire energy of the entire universe. Moreover, there is no evidence that such a special substance exists.

Similarly, there is wormhole technology. According to Einstein's general theory of relativity, the famous American physicist John Wheeler proposed that it is believed that there may be narrow tunnels connecting two different time and space in the universe. This kind of tunnel is called wormholes.

Dr. John is a scientist who proposed to create the term black hole. His theory has also been accepted by many physicists, but until now, no such space-time tunnel has been found.

There is another exaggerated technology, which is multidimensional space. The universe that humans can see is three-dimensional, but in fact, there is a higher dimensional space in the universe. If you can master a higher dimensional space, the spacecraft can pass through it and achieve extreme speed.

Unfortunately, these ideas are only focused on ideas. To achieve them, there are many technical difficulties that cannot be overcome, and some are even incomplete in theory.

Therefore, if spacecraft want to fly interstellar, the current technology can only be achieved by relying on conventional power!

The Soviets have developed and matured to be nuclear-powered rockets. With nuclear-powered rockets, spacecraft can carry less fuel and fly to a longer distance!

Therefore, the Soviet aerospace experts can only continue to work hard on nuclear-powered rockets. They did not simply increase the thrust of nuclear-powered rocket engines, but adopted more advanced controlled nuclear fusion engines!

Fission and fusion are two different ways. Compared with these two ways, fusion is far ahead.

Just as a reaction equation, if a fusion occurs, the energy released is several times that of fission, which means that fusion can release more energy. At the same time, by comparing the atomic weight, you can get a higher average energy! Fusion is a reaction carried out by light nuclei, with fewer nuclei. On average, the energy released is hundreds of times that of fission!

In other words, loading fuel of the same mass, fusion is hundreds of times more energy than fission provides!

And relying solely on the original fission, we can explore in the solar system. For example, more than ten years ago, fission atomic rockets flew to Mars frequently for investigation, and the fusion engine was enough to push spacecraft and fly out of the solar system!
