How its modules are laid out, how it was built and who lives on board now.
Assembly from 1998 to 2021. Drag to rotate it and tap a module to see what it is.
Unfolded diagram, not exactly to scale. Dashed outlines mark modules mounted above or below another one.

The International Space Station wasn't launched in one go: it was assembled in orbit from 1998 onwards, piece by piece, over more than forty assembly flights. The first module was Zarya, built in Russia and paid for by NASA; two weeks later came Unity, the first US node. The last big additions were the Russian Nauka laboratory and the Prichal node, in 2021.
The model and the plan are a diagram: positions and sizes are approximate, and the colours show which agency runs each module, not its real colour, which is almost always white or silver. Visiting spacecraft such as Crew Dragon, Soyuz or Progress are left out because they change every few weeks; you can follow them under Launches.
