Die ISS: Das teuerste Bauwerk der Geschichte

At an altitude of about 400 kilometers above the Earth's surface, where the atmosphere merges into the infinite blackness of space, the largest and most complex technological project in human history orbits our home planet. At a breathtaking speed of 28,000 kilometers per hour, the International Space Station, or ISS, circles our home planet. Every 92 minutes, it completes a spectacle of unimaginable beauty: a sunrise and a sunset alternate 16 times a day. For the astronauts on board, this is everyday life; for humanity on Earth, it is a shining symbol of what is possible when boundaries are overcome and nations reach for the stars hand in hand. The ISS is not merely a man-made object in space; it is an outpost of our civilization, a floating laboratory, and the foundation for humanity's future journeys to distant worlds like Mars.
