The International Space Station is one of the most remarkable achievements of the modern age. It is the largest, most complex, most expensive and most durable spacecraft ever built.
The International Space Station is one of the most remarkable achievements of the modern age. It is the largest, most complex, most expensive and most durable spacecraft ever built.
Its first modules were launched in 1998. The first crew to live on the International Space Station—an American and two Russians—entered it in 2000. Nov. 2, 2025, marks 25 years of continuous habitation by at least two people, and as many as 13 at one time. It is a singular example of international cooperation that has stood the test of time.
Two hundred and ninety people from 26 countries have now visited the space station, several of them staying for a year or more. More than 40% of all the humans who have ever been to space have been International Space Station visitors.
The station has been the locus of thousands of scientific and engineering studies using almost 200 distinct scientific facilities, investigating everything from astronomical phenomena and basic physics to crew health and plant growth. The phenomenon of space tourism was born on the space station. Altogether, astronauts have accumulated almost 127 person-years of experience on the station, and a deep understanding of what it takes to live in low Earth orbit.
If you’ve ever seen photos of the inside of the International Space Station, you’ve probably noticed the clutter. There are cables everywhere. Equipment sticks out into corridors. It doesn’t look like Star Trek’s Enterprise or other science fiction spacecraft. There’s no shower for the crew, or a kitchen for cooking a meal from scratch. It doesn’t have an area designed for the crew to gather in their downtime. But even without those niceties, it clearly represents a vision of the future from the past, one where humanity would live permanently in space for the first time.
November 2025, by coincidence, also marks the 10th anniversary of my team’s research on the space station, the International Space Station Archaeological Project. The long history of habitation on the space station makes it perfect for the kind of studies that archaeologists like my colleagues and me carry out.
