Crossing the boundaries of Earth and entering space is a great achievement or achievement in human history. The International Space Station (ISS) is a sign of this. Our curiosity about it is endless. Today we will learn some unknown things about the space station. So let's begin.
1. Everett Hale planned to build the first International Space Station in 1869. Then, in the early 20th century, Tisholkowski and Hermann Oberth added more plans. Later in 1929, Herman Potkonnik formulated a space station proposal in a book called The Problem of Space Travel.
2. Construction of this potential space station actually began in 1984 after the United States launched a project called "Space Station Freedom." But then it was not built as expected. Therefore, different countries jointly took up the project and named it "International Space Station" or International Space Station.
3. The space station, as we see it today, was originally not like that. Different parts of the station were launched into space by rockets from Earth at different times. It eventually became today's space station. But even this form is variable.
4. There is weightless space inside.
5. It travels a distance of 28,000 km per hour. At this speed, it takes 92 minutes to go around the world once.
6. Gravitational force does not exist here. Because of this, small objects and even people float here.
7. At regular intervals, the space station rises. Because if it doesn't, the space station will continue to descend at high speed and eventually burn up due to its friction with the Earth's atmosphere.
8. There is neither day nor night, just as there is nothing above and below.
9. The International Space Station is located about 400 kilometers above the Earth's surface.
10. The current space station took more than 13 years to build and required 42 spacewalks.
11. About 12 billion dollars were spent on its production.
12. Astronauts began living on the station after November 2000.
13. The space station weighs 4,20,000 kg and is 73 meters or 240 feet long with all solar panels extended. Its width is 109 meters or 360 feet.
14. 6 astronauts remain on the space station at all times. They do various scientific research there. They have 6 bedrooms, 2 bathrooms and a glass living room. From this room you can enjoy the beauty of space.
15. Astronauts see 16 sunrises and sunsets in 24 hours.
16. An astronaut stays on the space station for 6 months. Some have to stay there again for 12 months. Only one astronaut holds the record for the longest stay in space, i.e. 665 days.
17. After the Moon and Venus, this artificial satellite is the brightest visible from Earth.
18. Experiments were conducted on the astronauts after their return. In fact, this test is done to know exactly what changes happen in the human body after a long stay in space.
19. It takes a spacecraft 6 hours to reach this space station from Earth.
20. The space station is bigger than a football field.
21. So far, 15 countries have carried out their activities on the space station. The 15 countries are: USA, Canada, Russia, Japan and 11 other countries on the European Space Station. (United Kingdom, Germany, France, Spain, Norway, Sweden, Italy, Switzerland, Netherlands, Belgium and Denmark)
22. 44 computers are used to control various functions of the space station such as humidity, gravity, water production, etc.
23. For more than 3 decades, about 350 astronauts worked on the space station.
24. Long-term stays on the space station can cause muscle and bone loss in astronauts. For this he has to practice for 2 hours every day. In the two decades before 2020, a total of 239 astronauts from 19 countries stayed on the space station. 151 of them are US citizens.
25. A total of 14 astronauts have died so far in two spacecraft crashes on the way back from the space station.
26. Scientists in space work tirelessly to solve problems that researchers may face in the future when conducting space missions.
