Space tourism has aroused heated discussions. How far is space tourism from us?

According to the British "Daily Telegraph" report, the first space hotel is expected to open, and the wish to "stay in space" will come true. Naturally, the rent will not be cheap, and the cost for three nights will be 2 million (converted to more than RMB 28 million). The company planning to build a hotel in space is called Galaxy Suites Hotel.

Javier Claramonte, the person in charge of "Galaxy Suites Hotel" said, "'Galaxy Suites' has three suites. They look like pods, and each suite in them is filled with guests. Each one is sent into space using rockets. Customers can travel around the earth in 80 minutes and see 15 sunrises and sunsets a day. At the same time, customers can crawl on the walls of the streamlined house like Batman. "For bathing," Claramonte said, in zero gravity, visitors can take a bath in a room filled with small floating water bubbles.

There are 5 types of space tourism: special aircraft hyperbolic flight, that is, the aircraft suddenly climbs during the flight, reaches a breakpoint and then lands on a curve, and then climbs to the end of the curve. and the entire process of falling along a hyperbola from the endpoint. Its cost is lower, its technology is more complete, and its safety is more guaranteed. Suborbital flight means that after the spacecraft enters space, it leaves the earth's atmosphere on the surface of the earth and gradually enters the edge of space, about 100 kilometers from the ground. Because the speed driving force cannot keep up with the real spacecraft, it cannot A flight condition that can tightly orbit the Earth. There you can experience the weightlessness for several minutes and see the strange scenery of the earth that is so blue that it glows. Orbital flight means that we take a spacecraft to fly at a satellite flight speed of 7.8 kilometers per second, closely surrounding the orbit of the earth, and flying in a space orbit 200-400 kilometers above the ground. After entering orbit, it has been in microgravity. The tool for realizing long-term orbital travel is currently the International Space Station, where tourists can see the earth, see the aurora, and experience the joy of space flight in person. The space hotel has more holiday tourism characteristics than the international space station. The structure of the space station will be more than just a window, suitable for tourists to watch the earth and the sky.

Ordinary people can also travel in space. The term space tourism has been proposed for many years, but it is far from forming an industrial chain, and the road to the future is still long. Former NASA official John Mansfield said three "hundred times": "Space tourism must be a hundred times more cost-effective, a hundred times more reliable, and a hundred times more efficient." Only then will A large number of ordinary people can go to space for vacation.

Professor Jiao Weixin emphasized that for our country, the development of space tourism is a global trend and an important direction for the application of space technology and the development of the space industry chain. For such a promising industry The chain cannot be ignored. We also need to build our own space station and cooperate with the international space station. After the technology is more mature, we can also consider developing space tourism.
