Space X Dragon berthed to the International Space Station

Aboard the International Space Station, Expedition 31 flight engineers Don Pettit of NASA, Andre Kuipers of the European Space Agency and Joe Acaba of NASA grappled and berthed the SpaceX Dragon spacecraft to the station's Harmony module, marking a milestone in spaceflight history. Dragon became the first commercially developed space vehicle to be launched to the station to join Russian, European and Japanese resupply craft that service the complex while restoring a U.S. capability to deliver cargo to the orbital laboratory. Dragon is scheduled to spend six days berthed to the station before being detached and released on May 31.
