Before each launch, the modules underwent rigorous testing to ensure their functionality and structural integrity. Engineers and technicians spent countless hours inspecting every wire, valve, and circuit. They simulated the harsh conditions of space, including extreme temperatures, vacuum, and radiation exposure. The modules were then integrated with the launch vehicles, carefully secured, and prepared for liftoff. The launch day itself was a spectacle of human engineering and technological prowess. As the rocket ascended, the ground control teams monitored every aspect of the launch, from engine performance to trajectory accuracy. Once the module reached the designated orbit, the astronauts or cosmonauts on board initiated the docking sequence. This required precise maneuvering and alignment to ensure a secure connection between the new module and the existing ISS structure. The docking process was a delicate dance between the spacecraft and the space station, requiring the crew to carefully control the module's speed, orientation, and alignment. Each successful docking added another piece to the puzzle, gradually transforming the initial core modules into a fully functional space station. The assembly of the ISS was a testament to the power of human ingenuity and international collaboration, demonstrating that even the most ambitious projects are achievable with dedication and teamwork.
