Space Shuttle Projects

The STS-105 crew patch symbolizes the exchange of the Expedition Two and Expedition Three crews aboard the International Space Station (ISS). The three gold stars near the ascending orbiter represent the U.S. commanded Expedition Three Crew journeying into space, while the two gold stars near the descending orbiter represent the Russian commanded Expedition Two crew on their return to Earth. The ascending and descending Orbiters form a circle that represents both the crew rotation and the continuous presence in space aboard the station. The plumes of each orbiter represent the flags of the U.S. and Russia, symbolizing the close cooperation between the two nations. The Astronaut office symbol, a star with three rays of light, depicts the unbroken link between Earth and the brightest star on the horizon, the ISS. The names of Discovery's crew of four astronauts are shown along the border of the patch while the names of the Expedition crews are shown on the chevron at the bottom of the patch.
