Discovery's crew members are Commander Pam Melroy, Pilot George Zamka and mission specialists Scott Parazynski, Stephanie Wilson, Douglas Wheelock, Dan Tani and Paolo Nespoli of the European Space Agency. Tani will remain aboard the station for several months and return with the STS-122 crew. Current station Flight Engineer Clayton Anderson will return to Earth aboard Discovery.

Discovery's crew will add a module that will serve as a port for installing additional international laboratories. The Harmony module will be the first expansion of the living and working space on the complex since the Russian Pirs airlock was installed in 2001. The mission also will move the first set of solar arrays installed on the station to a permanent location on the complex and redeploy them.
