All five of the world's participating space agencies now have equipment parked at the station.
Five space agencies have vehicles or equipment at the space station now that the shuttle has docked.
The shuttle is delivering a human-like robot, the Robonaut 2, or R2.
The Endeavor and Atlantis shuttles are scheduled to make their final visits to the station later this year.
The shuttle Discovery docked for its final visit at the orbiting International Space Station, where all five of the world's participating space agencies now have vehicles or equipment.
"This is the first time all visiting vehicles have something represented," NASA mission control in Houston said on Saturday, after the oldest and most heavily traveled US shuttle linked up with the space outpost 220 miles over western Australia.
Japan's HTV vehicle, Russia's Progress and Soyuz craft, the European ATV-2 supply ship and the Canadian Dextre robot are all there, NASA said.
Discovery arrived in spectacular fashion, with American commander Steve Lindsey executing a "rendezvous pitch maneuver," a one-degree-per-second rotational back flip, before mooring at the space lab at 2:14 pm.
