Standing left to right are Mission Specialists Steven Smith, Jerry Ross, Lee Morin, Ellen Ocho and Rex Walheim; Pilot Stephen Frick; and Commander Michael Bloomfield. Mission STS-110 is the 13th assembly flight to the International Space Station. During four planned spacewalks, crew members will install the S0 Integrated Truss Structure (ITS), centerpiece of the orbiting International Space Station (ISS), at the center of the 10-truss, girderlike structure that will ultimately extend the length of a football field on the ISS. The S0 truss will be attached to the U.S. Lab, "Destiny," on the 11-day mission
