According to the report of the British "Daily Mail" on the 13th, traveling in space is a dream of many people. However, the "space ticket" of tens of millions of dollars makes space tourism only a money-burning game for rich people. A few days ago, several scientists at the Johns Hopkins Applied Physics Laboratory in the United States proposed a construction plan for an "interstellar train" launch system that can carry humans off Earth at a rate of about 20,000 miles per hour. The construction of the "Star Train" launch system takes 20 years and costs 60 billion U.S. dollars. However, it will be able to transport 4 million people each year to travel to space. The average person can spend just US$5,000 to realize the dream of space tourism!
Speed ​​is like a high-speed shell
According to reports, the "inter-satellite train" proposed by American scientists is actually a space launch system using the principle of magnetic levitation trains. James Powell, a scientist at the Johns Hopkins Laboratory of Applied Physics, said that humans can build a "vacuum launch pipeline" on the ground that is about 1,000 miles (1600 kilometers) long. Most of this "vacuum pipeline" is The sea level will operate, but the end will rise like a slope, and the highest “emission exit†position will be up to 12 miles (19.2 km) from the sea level.
The maglev train traveling in this “vacuum pipe†is what American scientists call “interstellar trainâ€â€”it is actually a sealed “space capsuleâ€. When the magnetic levitation “interstellar train†is accelerated in this vacuum pipeline, the theoretical maximum speed can reach around 20,000 miles (32 thousand kilometers) per hour, and when the “interstellar train†flies at incredible speed in the last few seconds When it reaches the 12-mile (19.2-kilometer) high vacuum pipe exit, it will be fired into near-Earth orbit like a high-speed projectile!
The budget equals NASA's total for 4 years
American scientists say that the technology for building "interstellar trains" is now fully available. Perhaps the only thing that needs to be considered is the safety of passengers. In order to let this "interstellar train" achieve this incredible "speed of launch" without affecting passengers. For their personal safety, the "Star Trek" launch system requires the construction of a large number of "ground vacuum orbits". It also needs to take measures to prevent ultra-sonic trains from being torn into pieces by the surrounding air.
American scientists suggest that the "interstellar train" system is best built in polar regions such as Alaska, Northern Canada, Greenland, Siberia or Antarctica. They estimate that it will take 20 years to build an "inter-satellite train" system that can carry passengers into space tourism, and the construction budget will be as high as 60 billion U.S. dollars, equivalent to about 4 years of NASA's total budget.
Although the construction costs of the "interstellar train" system may sound very large, the total budget that the United States has put into the "space shuttle" in the past 30 years is almost three times as high as this. Moreover, once the "interstellar train" system is completed, the cost of launching cargo, satellites, and passengers into space will be rapidly reduced, and the cost of shipping goods into space will be reduced by around $50 per kilogram. While ordinary people only need to spend $5000, they can realize the dream of space tourism.
Will bring a leap for human civilization
Scientists at the Johns Hopkins Applied Physics Laboratory in the United States also stated that this "interstellar train" launch system will not only revolutionize future space tourism, but also have a "most important role" - defense Earth. At present, humans have no feasible defense measures against potential threats such as possible asteroids or comets, but with this "interplanetary launch system," the situation will change immediately, and scientists can deploy multiple early warning systems in space. A series of high-speed interceptors were deployed in the Earth's orbit. Once the threat of asteroids hitting the ground was measured, they could immediately proceed to effective interception.
In addition, with this "Star Trek" launch system, humans can launch more solar panels into space, making efficient use of solar energy possible; in addition, human astronauts will be able to more easily go to "asteroids" for mining, as Earth brings incalculable resource wealth. American scientists wrote in their proposal: “Our solar system is very rich in resources. The energy that the sun shoots at our earth every day is about 10,000 times more than we need. There are also many precious minerals on the asteroids and comets. They can support human economic development for the next 1000 years. The completion of this 'inter-satellite train' system will bring about a new leap forward for human civilization, in addition to providing a 'safety net' for life on Earth." (Lancy )
Pen painting is a kind of painting made by filling or dipping ink with ordinary pens or special metal pens. It is a line art and belongs to an independent painting category. By controlling the speed and strength of the pen grip, you can draw lines of different thicknesses. Pen and ink painting has a unique aesthetic feeling and is very interesting. It is characterized by the decisive use of the pen, the strong and smooth lines, the strong contrast between black and white, and the fine and compact picture effect. It can not only depict the painted things in detail, but also make a high degree of artistic generalization. Portrait, still life, landscape and other themes can be expressed.
