despite the fact that Weizhen Virgin Galactic, a commercial company that provides sub-track flying) has not been able to make commercial space flight, but it is surprising that the concept of space hotel is unveiled, which allows you to spend a day in the flat-flow layer.
Virgin Galactic revealed the space suit designed with Under Armour last year to showcase the vision of space travel. Sadly, he can’t smoothly carry out business flight plans for the cause of the epidemic.
However, recently, a space travel plan is better than that of Virgin. The version of Galactic stays in space for a while, and the program can stay completely in space. This is a so-called space hotel.
According to the US “World Daily” report, a space construction company in the United States announced that it will build nearly track in 2025 A space hotel, the hotel has theme restaurant, cinema, spa, etc., will also build a space room that can accommodate more than 400 people. The report claimed that the space is expected to start operating in 2027.
First, it creates a huge circular observation station outside the Earth. It consists of 24 modules, each module means a room. In one module, the living space is 20mx12m. Of course, not all modules are used as hotel room. Each module is classified according to its use, and is planned to be used as laboratory, crew, fitness center and performance hall.
The scale of the traveler space station created in this way is three times the international space station. The international space station is the largest structure in human beings currently in space. Only diameterIt is 200M, which is about two times the international space station, which is about 2418 tons, which is five times the weight of the international space station. 
The area is also unbeatable, and if this hotel is completed, it will be the largest building in history.
Due to the large area, the number of people can live is unparalleled. According to the track assembly company (OAC) of the project, the traveler’s space station can accommodate at least 316 people, up to 440 people, and have prepared 44 escapes for emergencies.
All power is from solar energy, and the panel of the solar panel of the solar panel than the international space station can be supplied to 440 people.
The more surprising is that OAC announced that it will open space hotel in 2027. It is said that from 2025, the Rocket will undergo assembly process.
But the biggest problem they face is elsewhere, such as creating artificial gravity. Unlike the international space station, the project is designed for tourism, which can be accommodated for long-term accommodation, so it cannot be in a zero-gravity state during the entire stay. 
This is because, unless you are a researcher, there are very few ordinary people spend a long time under zero. In particular, in order to solve problems such as toilets and shower, it is necessary to achieve normal life by gravity, with artificial gravity. If an artificial gravity is generated, then it is possible to run and jump, will become possible.
OAC indicates that the prototype is currently being developing prototypes, researchers, pilots, and designers who are mobilizing NASA. If the first prototype is developed, it may be tested on the Earth, and then deploy it on the low orbit to perform rigorous artificial gravity testing.
OAC emphasizes that the project is completely designed as private travel business. ObjectiveBefore, they have raised approximately $ 1 million in investment and plan to obtain additional investment in the future project progress. 
OAC expects guests at the first space hotel to pay about $ 50 million, about 327 million yuan. Obviously this is not a general person to go.
