JSC2002-E-27067 (1 July 2002) --- Astronaut Sandra H. Magnus prepares for the STS-112 mission by participating in a hardware-moving simulation. The mission specialist rehearses setting up work for assigned space-walking crewmates in the nearby giant pool of the Neutral Buoyancy Laboratory (NBL) at the Sonny Carter Training Facility. Magnus and Expedition Five flight engineer Peggy A. Whitson (already aboard the orbital outpost when this training took place) will be operating the controls of the Space Station Remote Manipulator System (SSRMS or Canadarm2) during the mission's task of installing the station's S-1 truss. Astronauts David A. Wolf and Piers J. Sellers, who would be suited up and standing by in the airlock during this activity, will follow Magnus' set-up work with a space walk.
