They joined Thomas Reiter, who had arrived at the ISS on 6 July 2006 aboard Space Shuttle "Discovery" during mission STS-121.  In December 2006, "Discovery" mission STS-116 brought Sunita Williams to replace Reiter as the third member of Expedition 14.

The main purposes of the mission were to test new safety and repair techniques introduced following the "Columbia" disaster of February 2003 as well as to deliver supplies, equipment and European Space Agency (ESA) astronaut Thomas Reiter from Germany to the ISS. Dr. Ulf Dietrich Merbold (born June 20, 1941) is the first West German citizen and second German native (after Sigmund Jähn) to have flown in space.  He is also the first member of the European Space Agency Astronaut Corps to participate in a spaceflight mission and the first non-US citizen to reach orbit in a US spacecraft.  In 1983, he and Byron Lichtenberg became the first Payload Specialists to fly on the shuttle.
