xvi Figure 3. Composite image of the fully assembled ISS with key elements noted. (Top) View from the front-looking aft. (Middle) View from below (i.e., nadir) looking up at the ISS. (Bottom) View from above, looking down on the ISS. Orientation of the ISS is with respect to normal attitude, which is discussed further in Chapter 8. These images were compiled from dozens of photographs taken during the fly-around of the Space Shuttle Endeavour after it undocked and flew around the ISS in May 2011 during one of the last missions to the outpost. This picture also shows the European Automated Transfer Vehicle, the Russian autonomous cargo vehicle Progress, and the Russian Soyuz spacecraft that transports the crew to and from the space station. The components are defined in Table 2.
