It’s bigger than you think
The cramped interior views of the ISS give the impression that it’s relatively tiny, but the orbiting lab is surprisingly big. The habitable and operational area within the station surpasses the size of a six-bedroom house, featuring six sleeping areas, two restrooms, and a gym.
The exterior portions are likewise large; the wingspan of the solar array, measuring 356 feet (109 meters), exceeds the length of an Airbus A380, the world’s largest passenger aircraft, which spans 262 feet (80 meters). The ISS measures 356 feet (109 meters) from one end to the other, just one yard less than the total length of an American football field, including the end zones. Additionally, eight miles of wiring form the electrical power system within the space station. In total, the ISS weighs about 925,335 pounds, or 420 metric tons.
