The International Space Station (ISS) has marked a major milestone—25 years of continuous human habitation. Over the past quarter-century, 162 astronauts from 12 different countries have called the ISS their home, contributing not only to groundbreaking assembly and research, but also leaving behind personal touches that make the station unique.

The Human Touch on the ISS
Each astronaut who lived and worked on the ISS didn’t just help advance science; they left a legacy. Crew members added decals, mission patches, and memorabilia to the station’s interior, making it a living museum of international cooperation and exploration. These personal marks serve as a reminder of the human spirit that fuels space exploration and foster a sense of camaraderie among crew members from around the globe.
International Collaboration and Scientific Progress
The ISS stands as a testament to what nations can achieve together. Collaboration among 12 countries has led to countless scientific breakthroughs, from medical research to advancements in technology. As the space station orbits above, its walls tell a story—not just of science and engineering, but of the people who made it all possible.
