Expedition 12 is nearing conclusion. Commander Bill McArthur and Flight Engineer Valery Tokarev wrap up six months in space with a return to Earth April 8. The next crew, Expedition 13 Commander Pavel Vinogradov and Flight Engineer Jeff Williams, is preparing for launch on March 29. Brazilian Space Agency astronaut Marcos Pontes joins them on a Russian Soyuz spacecraft. Pontes will spend about a week on the station before returning to Earth with McArthur and Tokarev.

The result of a 16-nation partnership led by the United States, the station is the largest international space project in history. The first station crew arrived on Nov. 2, 2000. Twelve crews have lived on the station conducting assembly and research work. For information about the station, its missions and crews, visit:
