International Space Station

Every docking port is full. The modules are glass: click any module or spacecraft, take the tour, or fly with the keyboard.

About your request: three Dragons at once is not possible. Dragon only docks at the two International Docking Adapters on Harmony, so two is the most there have ever been (first in December 2020: Crew-1 and CRS-21). To fill all eight ports this model has 1 Soyuz, 3 Progress, 2 Dragons (Crew and Cargo), a Cygnus XL and an HTV-X.
