deployment expanded the Space Station, allowing it to grow from the size of a three-bedroom house, to the space equivalent of a typical five-bedroom house, once the Japanese Kibō and European Columbus laboratories are attached. The Space Station robotic arm, Canadarm2, is able to operate from a powered grapple fixture on the exterior of Harmony. Harmony is equipped with eight International Standard Payload Racks: four avionics racks and four for stowage or crew quarters. The first two were delivered on STS-126 and the second two on STS-128. After the cancellation of the Habitation Module, Harmony was chosen to house the American Crew Quarters. Construction agreement In an agreement between NASA and the European Space Agency, the company Thales Alenia Space, built Harmony at its facility in Turin, Italy. Harmony arrived on 1 June 2003 at the Kennedy Space Center in Florida after its flight in an Airbus Beluga oversize cargo vehicle. Following post transportation inspection, the Italian Space Agency (ASI) formally handed over Harmony to the European Space Agency (ESA). From there, ESA formally transferred ownership of Harmony to NASA on 18 June 2003, taking place in the Space Station Processing Facility (SSPF) of the Kennedy Space Center. The handover of Harmony completed a major element of the barter agreement, between ESA and NASA, that was signed in Turin, Italy on 8 October 1997. Paolo Nespoli, an ESA astronaut born in Milan, Italy, accompanied the Harmony module aboard STS-120 as a mission specialist. Launch Harmony was launched on 23 October 2007 aboard of the STS-120, as the primary component of assembly mission ISS-10A. On 26 October 2007, the station's Space Station Remote Manipulator System (SSRMS) removed Harmony from the shuttle cargo bay and temporarily mated it to the port side of Unity and, on 27 October 2007, the crew entered in Harmony. After the Space Shuttle was departed, Harmony was relocated to the forward dock of the Destiny laboratory. It required three EVAs by the station crew to complete the installation. Connecting modules and visiting vehicles Harmony was the first permanent living space enlargement to the ISS after the Pirs docking compartment was added in 2001. The Expedition 16 crew moved the Pressurized Mating Adapter (PMA-2) on 12 November 2007 from Destiny to the forward berth of Harmony. The combined PMA-2/Harmony unit was subsequently berthed to its final destination at the forward end of Destiny on 14 November 2007. All
