Tourism forms of space tourism

Apart from the four relatively formed forms of "space travel" mentioned above, aren't there any new projects to enrich space travel? Imagine a resort hotel suspended for 400 kilometers on the ground. It is reported that the Russian space department is planning to jointly design a miniature "space hotel" by the government and enterprises. Some American engineers have also suggested that a cabin that flies around the earth for a long time can be built with light inflatable materials, and its "room fee" will be slightly cheaper than traveling to the space station.

Some American and Russian experts are still exploring the use of nanomaterials to make "space elevators". One end of the "elevator" sling is fixed on the platform on land or sea, and the other end firmly grasps the spacecraft flying synchronously with the earth, about 36 thousand kilometers from the ground. The ultimate goal of this study is to lift people and goods in the solar elevator by tens of thousands of kilometers, and the transportation cost per kilogram load is estimated to be only 10 USD. If the idea of "space elevator" can be realized, space tourism and space passenger and cargo transportation will usher in new development opportunities.

Space tourism is an orbital flight, which can be realized mainly by the International Space Station, and the "means of transportation" for tourists to and from the space station are mainly the Russian Soyuz spacecraft and the American space shuttle. However, the unit price of this kind of tour exceeds 20 million dollars. To this end, some international institutions and enterprises have turned their attention to various cheap "quasi-space tourism". "Quasi-space tourism" mainly includes parabolic flight of aircraft, high-altitude flight close to space and suborbital flight. In order to maintain its superiority in the field of space tourism, American space exploration company also announced the "Moon Tourism" plan. According to this plan, visitors will first go to the International Space Station, stay in the station for a week, and then take the Soyuz spacecraft to the moon to enjoy the "Moon Scene" at a close distance from the orbit of the moon 160 km. American "space exploration" company has launched a new tourism project-spacewalk ambitiously.
