The STS-111 patch symbolizes the hardware, people, and partner nations that contribute to the flight. The Space Shuttle rises on the plume of the Astronaut Office symbol, carrying the Canadian Mobile Base System (MBS) for installation while docked to the International Space Station (ISS). The mission is named UF-2 for ISS Utilization Flight number two. The ISS orbit completes the Astronaut Office symbol and is colored red, white, and blue to represent the flags of the United States, Russia, France, and Costa Rica. The Earth background shows Italy, which contributes the Multi Purpose Logistics Module (MPLM) used on this flight to re-supply ISS. The ten stars in the sky represent the ten astronauts and cosmonauts on orbit during the flight, and the star at the top of the patch represents the Johnson Space Center, in the state of Texas, from which the flight is managed. The names of the STS-111 crew border the upper part of the patch, and the Expedition Five (going up) and Expedition Four (coming down) crews’ names form the bottom of the patch.
