Space tourism costs more than $20 million each time. Why is space tourism so expensive?

The main reasons why the cost of every space trip is very high are the cost, the rockets needed to go to space, which will consume a lot of fuel, and the safety, all of which need to be adequately guaranteed.

For adventurous people, space is very attractive, and space attracts all those who dare to take risks. A complete space voyage will experience the acceleration overload and landing impact when the spacecraft takes off, the tremor and roar of the rocket engine, and the horrible picture of burning like a meteor when returning to the atmosphere, which will bring infinite excitement to adventurous tourists. This is unmatched by experience tourism or sports such as aviation, navigation, surfing, speeding, rock climbing and diving in the earth's atmosphere.

The most attractive thing about space travel is that when the spacecraft gets rid of the shackles of gravity, it is in a completely different life background from the ground environment. In the case of microgravity or weightlessness, tourists can fly, sleep, sit and stand upside down in various positions as in fairy tales. You can also feel the unique feeling of eating and drinking in space.

Because sending a spacecraft into low-earth orbit requires the use of expensive rockets and consumes a lot of fuel, the cost of sending a payload of 1 kg into low-earth orbit is more than $20,000 for both the space shuttle and Soyuz spacecraft. In addition, sending people into space requires higher safety and reliability, as well as complicated life support system and manned return, which is expensive. High cost is only one aspect, and the scarcity of flight resources is another important constraint factor that makes orbital flight difficult to popularize. The ability of human beings to enter space is still very limited, especially in the days when the American space shuttle retired and commercial space companies have not developed manned spacecraft. Astronauts can only rely on Russian Federation spacecraft to travel between heaven and earth, and the United States needs to pay a huge air ticket to Russia to get a "seat."
