International Space Station

Sixteen nations assemble a 420-tonne laboratory crewed continuously since 2000.

The first module, Zarya, launched in November 1998 and crews have lived aboard without interruption since November 2000. The station spans about 109 m and has hosted over 280 people from 20 countries. It is the largest structure humans have built in space.
