According to the current scientific level, what are the ways to realize space travel?

With the development of people's economy, China has traveled all over the world, and tourism has been integrated into our daily life. In recent years, countries are also striving to develop the space industry. Bian Xiao is very confident that in the near future, humans will eventually land on Mars.

So, for you now, seeing the continuous progress of space technology, have you considered space travel?

Looking up at the starry sky at night, you can't help falling into the daydream of traveling in space. If you can really travel in space, you will definitely have an unprecedented experience. You can not only enjoy the feeling of weightlessness, but also see the novel and exciting space scenery, which makes your imagination feel beautiful.

At present, space travel is divided into four ways, namely parabolic flight of aircraft, high-altitude flight close to space, suborbital flight and orbital flight. Let's get to know it together!

The path of space travel 1: parabolic flight

Parabolic flight is not real space tourism. Why do you say that? Because it only makes tourists feel weightless, and it only lasts for half a minute.

As we all know, one of the necessary skills of astronauts is to be able to overcome the problem of weightlessness in order to complete tasks in space. But the training ground is definitely not in space, so it needs to be able to simulate weightlessness. Parabolic flight is one of the weightless environments simulated by astronauts during training.

The parabolic flight of the plane will run along an elliptical orbit around the center of mass of the earth in about 22 seconds. During entering this elliptical orbit, a microgravity environment of plus or minus 0.05G can be obtained.

If you want to experience it, you can take it to Russian astronaut training. Il -76? Wait for the plane to feel the weightlessness caused by parabolic flight, about half a minute. Of course, it also costs a lot, about $5,000.

Space Travel Route 2: Flying at High Altitude

Flying at high altitude is about 24 kilometers from the ground. This height is close to space. Looking down, you can see the topographic curve of the earth under your feet. Looking up, you can see the dark sky overhead and feel the boundless space environment.

Although this is not a real space tourism, it can let visitors experience the feeling of being only at high altitude. Is there a travel tool for flying at high altitude in Russia? MiG -25? And then what? MiG -3 1? The cost of a high-performance fighter to experience space travel is about 10000 USD.

Space travel route 3: suborbital flight

To understand suborbital flight, we must first know where suborbital flight is.

Sub-orbit, also known as adjacent space or air-space transition zone, generally refers to the area 20 km ~ 100 km from the ground, which is the area with the highest flying height of aircraft and the lowest orbit height of satellite at present. In addition to space travel, this area is also used for intelligence gathering, reconnaissance and surveillance, communication support and air-to-ground operations.

Sub-orbital flight can produce a sense of weightlessness for several minutes, and it can produce a sense of weightlessness for several minutes when the rocket engine is turned off and re-enters the atmosphere, thus achieving the purpose of space travel experience. American private manned spacecraft? Spaceship one? And planned by Russia? C-XXI？ You can board a tourist spaceship. The cost of this kind of space tourism is about $654.38 million+10,000.

Space travel route 4: orbital flight

Orbital flight is the vast majority of human space activities. This is very different from the first three ways, because it can be regarded as real space travel, and its ticket price is as high as 20 million dollars.

The biggest difference between orbital flight and suborbital flight is that the launch speed of suborbital flight can't reach the first cosmic speed required to orbit the earth once, so it can't orbit the earth once.

After reading these four ways of space travel, do you feel a surge of emotion? For ordinary people now, space travel is a project that only very rich people can experience, but Bian Xiao believes that with the rapid development of science and technology, this tourist route will be opened up, and it is no longer a fantasy to want to go to heaven.
