How to let the public enjoy space travel?

At present,? There are four main ways of space tourism: parabolic flight of aircraft, high-altitude flight close to space, suborbital flight and orbital flight. We must admit that the cost of each method is not cheap.

Parabolic flight is not a real space tourism, but only allows visitors to experience the feeling of weightlessness several times in space. Using a weightless plane to fly a parabola, visitors can experience weightlessness for about half a minute every time they fly a parabola. Professional astronauts also use this method to experience weightlessness in training.

What is the cost for space tourists to experience the hard-to-simulate weightlessness on the ground by taking the Russian Il -76 weightless plane? 5000 dollars, but not including the round-trip ticket to Russia.

The parabolic flight of weightless aircraft can experience weightlessness.

High-altitude flight close to space is not real space tourism, it is to let tourists experience a very empty feeling. When tourists fly to an altitude of 18km, they can see the curve of the earth below and the dark sky above, and experience an endless sense of emptiness.

At present, the planes that can be used to complete this kind of high-altitude mission are Russian high MIG -25 and 3/KLOC-0 fighter planes, which can fly to an altitude of about 24 kilometers. How much is the fare for each flight of this trip? 1 10,000 USD, including the cost of staying in Moscow for two days.

So-called? Sub-orbital flight means that the aircraft enters the space about 100 km from the ground, but does not fly around the earth (if the aircraft flies around the earth more than once about 100 km from the ground, it is called orbital flight).

Sub-orbital flight tourism is to send tourists to the edge of space at a height of 100 km, and then return to the ground immediately, that is, tourists fly up and down in a spaceship almost in a straight line.

Using this flight mode, visitors can feel weightlessness for a few minutes, and they can also enjoy thousands of kilometers of the curved surface of the earth and appreciate the beautiful earth, and the cost is much cheaper than that of orbital flight. 1 flight? About 200,000 dollars. It is reported that many foreign companies will start this business next year.

Orbital flight is a real space tourism. The space tourism tool to achieve orbital flight is mainly the International Space Station, and the transportation tools for tourists to reach the International Space Station are mainly the Russian Soyuz spacecraft and the American manned dragon spacecraft.

Orbital flight allows visitors to enjoy novel space experiences, because visitors can live in the spacious "International Space Station" for at least one week. At present, seven tourists have made eight orbital flights to the International Space Station, including Simone, the father of Word who has experienced two space trips.

Of course, the cost of orbital flight travel is very high, including all kinds of training expenses. What was the cost of going to heaven every time before? 20 million to 35 million dollars, and now it has risen at least? 55 million dollars, so most people can't afford it.
