The most valuable machine ever created by mankind. This is what German astronaut Alexander Gerst called the International Space Station. But now, 27 years after the first components were launched into space, the ravages of time are eating away at these machines and they are on the verge of extinction. At the beginning of 2028, the ISS (International Space Station), which flies around the earth at an altitude of 400 kilometers, will gradually lower slightly; two years later, controlled collisions of 450-ton devices the size of football fields would begin in the South Pacific. Last year, SpaceX was awarded a contract to develop the spacecraft that will push the ISS in its desired direction.
