One Orbital Lab, 110-Plus Countries, 4,000-Plus Experiments
NASA's numbers for the International Space Station: more than 25 years of research, scientists from more than 110 countries, and more than 4,000 experiments conducted in microgravity.
One facility, used by researchers from over a hundred countries, is the unusual part of the arrangement. The count measures activity rather than results — it is a record of how much has been tried in weightlessness, not of what any of it found. But as a measure of a laboratory's reach, the country total is the striking one.

The number that sticks is 110 countries. One shared facility drawing researchers from that many national systems is a different kind of collaboration from a single agency's mission.
A count measures attempts, not results. Four thousand experiments says the station is busy; it doesn't say which of them produced something worth keeping.
