What is a space "hotel"?

Humans can enjoy all kinds of star-rated hotel services when traveling on the earth. Hotel is an important part of tourism, and it has also become a major landscape of modern cities. 2 1 century, mankind will usher in the era of space tourism, and by that time, space hotels will inevitably emerge.

In fact, today, when human beings conquer the universe, the space station is the embryonic form of the future space hotel.

The space station is a manned spaceship for many astronauts to visit, work and live. In a sense, it is a space "hotel" for astronauts.

The first space station in the world was sent into space by the former Soviet Union in 197 1 and its name was "Salute" 1. It consists of docking module, track module and service module. The docking module is designed for docking with spacecraft, and it is the only way for astronauts to enter and leave the space station. The orbital module is similar to the guest room of a space "hotel". It consists of two cylinders with diameters of 3 meters and 4 meters respectively. The cabin maintains the same climate as the earth, and is the place where astronauts work, rest, eat and sleep. The service cabin is equipped with engine and fuel. Salute space station weighs 18 tons and is about 14 meters long. It generally runs in an altitude orbit 200 ~ 250 kilometers from the earth's ground.

The former Soviet Union launched seven salute space stations from1971~1983 * *. Astronauts have worked here for 236 days.

1986 The former Soviet Union launched the second generation space station "Peace". It is a building block structure, which is composed of a plurality of cabins after docking in space. Its docking module has six interfaces, which can dock six scientific experiment modules. With a total weight of11ton, Peace is a giant in space.

"Peace" has taken shape as a permanent space station. Originally designed for 5 years, it has been running for 12 years. Although it failed continuously in 1997, it was always near misses. As it is the only space station operating in space at present, it is a bit rare, and Russia intends to let it work for another few years.

"Peace" began commercial operation shortly after its operation. Its first business comes from American Payload Systems, a microgravity experimental device of which will stay in space for 56 days. It must be "Peace". Peace has earned a lot of money for this.

1In February, 1995, Americans who were unwilling to be lonely caught up with Mir on the space shuttle Discovery and held a historic handshake. American and Russian astronauts face each other through the window and wave to each other. The shortest distance is only 1 1 meter. 1997, two American scientists boarded the American space shuttle "Peace" to conduct space research with Russian astronauts.

The first space station in the United States was called Skylab, which was launched in May 1973. "Sky Lab" is much bigger and more advanced than "salute". It is 36 meters long and weighs 82 tons. Its orbital module is divided into upper and lower floors, the upper floor is the working area, and the lower floor is the living area, with bedroom, dining room and bathroom. There is oxygen supply in the cabin, and the temperature is about 20℃. The docking module has two interfaces and can dock two spacecraft at the same time. "Sky Lab" has been running in space for 6 years, and it entered the atmosphere and burned in July of 1979+0.

In order to change the situation that Russia monopolizes the space station at present, the United States is developing the third generation space station-Freedom. "Freedom" has a unique structure, like a huge and long hanger, which can easily hang the working cabin, living cabin and service cabin. The length of the pylon is 1 10 meter, which can be used to form different space stations according to user's requirements.

At the end of the 20th century and the beginning of the 20th century, the permanent space station jointly built by the United States, Russia, Canada, Japan and the European Space Agency will go into space.

Is there a real space hotel construction plan? In 265438+1920s, the Japanese put forward the idea of building a space hotel: this hotel is about 450km away from the earth's surface, with various rooms, gyms, dance halls and bars, and passengers can travel in space for six days. Training related skills on the earth two days ago; On the third day, we took the space shuttle and arrived at the Space Hotel 1 hour later. Passengers can stay here for 4 days and enjoy the wonderful time of inviting them to visit space.
