The STS-102 crew insignia depicts the International Space Station as it looked when Space Shuttle Discovery was docked. Visible elements include the P6 and Z1 trusses, solar arrays from the Russian segment, 2 Pressurized Mating Adapters, and the Multi Purpose Logistics Module that was temporarily attached to the underside of the Unity Node. The numbers "102" represent the mission tail number. The red, white, and blue ribbons surrounding the space station represent that this is a crew rotation flight. The colors represent the nationalities of the crewmembers (Russian and American). Underneath the ribbons are the flags of the three nations who are the major contributors to the mission (from left to right: Russia, United States, Italy). The names of the 4 permanent crewmembers are displayed in gold around the top of the emblem. Attached to the bottom are six names depicting the six rotating crewmembers (Expedition 2 on top and Expedition 1 on bottom).
