Une maison de 420 tonnes qui fonce à 28 000 km/h dans le vide — avec 6 humains qui dorment à l'intérieur 😶 Voilà comment la ISS survit réellement dans l'espace. #Science #technologie #physique #darktech #creatorsearchinsights

How a house of 420 tons can be founded at 28,000 km/h, at 400 km/h from you, with six humans who sleep peacefully inside. The International Space Station is not in the sky, it is in the void. No air, no gravity, no heat. However, it is the Brite of Life in permanence since 2000. First mystery, why they do not fall? The gravity of the Earth is still there, but it is moved so quickly that, during which it falls, the Earth runs under it. It is in short-lead, permanent. It falls without ever touching the ground. That is it, being in orbit, rat the planet continues. Second problem, air. There is no air, then the factory station. It uses electricity to break the molecules water in hydrogen and oxygen. Exactly how it starts. The water is also recycled. Everything, the current of the crew, the condensation of walls. And yes, their own urine. Filter, purify, redeveloped to the potable. 93% of the water is recycled. Third problem, the temperature. On one side, the sun heats up the station at more than 120 degrees. On the other side, in the shadow, it is less than 157 degrees. Difference of 280 degrees. On the two phases of the same wall. To survive that, the station is enveloped by isolated cars. And a radiator system is circulated by liquid ammonia to redistribute heat from one side to the other. Fourth problem, energy. 8 immense air, larger than 50 feet of football. Capture the light of the sun and fuel all the station. When it passes in the shadow, batteries take it away. Fifth problem, the orbit of the lines. Frotement residual from the atmosphere. A film but constant. It is lost from the altitude of the station. Several times a year, the engine goes down to the ground. Without that, it would crash. Inside, six astronauts live, work, founding of the science. Dorm attached to walls to not arrive in the void. They see 16 waves of the sun every day. The Earth defles all the 40 minutes. Fabricate its air, recycle its water. Maintain the cold and the extreme hot water. Woke up in the void without falling. The International Space Station is not a machine. It is a human bubble, suspended from the void. And now, you know how.
