The International Space Station is a habitable artificial satellite launched in 1988, that orbits the Earth 400km above our heads. It doesn’t look that much, but remember space starts at Karman line only 100km away upright… that’s where the atmosphere becomes too thin to support aeronautical flight. The Gravitational strength in the ISS compared to the surface of the Earth is 89% Why does it seem the ISS has no gravity? The ISS serves as a microgravity and space environment research laboratory in which crewmembers conduct experiments. The effective gravity inside the ISS is very close to zero, because both astronauts and the station itself are simultaneously falling down. The ISS never hits the ground because its horizontal speed (27000Km/h, it completes 15.50 orbits per day). When the Station has fallen 1 meter, because of this horizontal speed and the...
