Introducing the International Space Station's Expedition 14 crew emblem. The Roman numeral XIV suspended above the Earth against the black background of space symbolizes the 14th long-duration mission to the outpost. The five stars honor the astronauts and cosmonauts of missions Apollo 1, Soyuz 1, Soyuz 11, Challenger, and Columbia, who gave their lives in the pursuit of knowledge and discovery.A veteran crew will fly aboard the International Space Station this fall and winter into 2007. They will work to expand the complex now that three crew members are aboard once again. Making his fourth flight into space, NASA astronaut and Navy Capt.

She will replace European Space Agency astronaut Thomas Reiter as the third expedition crew member on the station for her six-month mission.Also, American businesswoman Anousheh Ansari will fly with the Expedition 14 crew to the International Space Station as a spaceflight participant.
