The International Space Station (ISS) was built through the collaboration of five space agencies: NASA, Roscosmos, JAXA, ESA, and CSA. The construction began in 1998 with the launch of the Zarya module, the first component of the station. Over the years, numerous modules, including living quarters, laboratories, and docking ports, were added to the ISS through a series of complex and carefully planned missions. Each module was transported into orbit by either the Space Shuttle or Russian rockets and then attached to the existing structure through a series of spacewalks by astronauts. The ISS is a marvel of engineering and international cooperation, demonstrating the potential for humans to work together to achieve ambitious goals in space exploration.
