Four "ordinary people" who travel in space are actually not ordinary at all.

Many people only know that space exploration technology company recently sent four ordinary people into space. But I don't know what's behind it is actually not ordinary at all. It can be said that it is carefully designed, which is mainly reflected in the following three points:

The mission of Space Exploration Technology Company is called "Yue Ling 4" manned space mission, which sounds no different from the past, but it is indeed the first space travel without professional astronauts in the world. To put it mildly, it can be said that it is devoted to scientific exploration and the first step for civilians to enter space. To put it mildly, this launch trip is a life adventure trip, which will go up in smoke if you are not careful. Musk is also really awesome, designing the "dragon spacecraft" of this flight to fly completely autonomously. Theoretically, this space travel belongs to fully automatic flight, or remote control flight. This is not the same as Tesla's autonomous driving. After all, the car can stop at any time, but the spaceship is difficult to stop, and there are no professional astronauts in the cabin.

Although the news said that four ordinary people were sent into space, in fact, these four ordinary people are not ordinary at all.

This combination can be said to be carefully designed for the success of the task and commercial promotion. They complement each other and can easily accomplish this task, and their identities can also conform to the concept of "ordinary people".

As we all know, it takes a very high speed for a spacecraft to break away from the earth's gravity and enter the earth's orbit. The dragon spacecraft of this mission is designed to fly around the earth at a speed of 27,000 kilometers per second. In order to reach such a high speed, the spacecraft must be accelerated by the power of the rocket. And ordinary people can't bear this acceleration. Therefore, in order to cope with this space flight, four passengers spent six months in flight training. Training programs include flying centrifuges and fighter planes, launching and re-entry training in the space capsule simulator of Space Exploration Technology Corporation, and trekking to Mount Rainier in Washington State in the snow. At the same time, space exploration technology company conducted many experiments in the early stage of this mission. Only the first few times were for NASA to transport astronauts to the International Space Station.

In a word, space travel is not possible for ordinary people at present. However, Musk is opening this market, and his space exploration technology company is constantly reducing the launch cost and difficulty. Maybe in the near future, ordinary people can really go into space.
