Some spacecraft dock with the International Space Station and others berth with the station.
Docking: The spacecraft can maneuver and attach to the station by itself. The Russian Soyuz and Progress vehicles can do this.
Berthing: An astronaut uses the station’s robotic arm to capture the spacecraft and maneuver it to the attachment site. This is the process for automated vehicles including Dragon (SpaceX), Cygnus (Northrop Grumman), HTV (Japan Aerospace Agency), and ATV (European Space Agency).
