On November 2, 2000, the first resident crew (Expedition 1) docked at the International Space Station (ISS). Two Russian cosmonauts and American Commander Bill Shepherd stayed on the ISS for about four and a half months.The crew of Expedition 1 had many responsibilities. They set up computers, communications devices, and carbon dioxide removal systems on the ISS. Three space shuttle missions docked with the ISS while Expedition 1 was living there. Shuttle astronauts delivered supplies and conducted experiments. One of the most crucial pieces of cargo was the ISS’ signature photovoltaic array, which powers the space station. Even everyday tasks, such as setting up a food warmer or exercise equipment, was made difficult in zero gravity with limited supplies.As of September 2014, the ISS is home to Expedition 41—a six-person Russian, American, and German crew. Members of Expedition 41 are studying seedling growth, meteors entering Earth’s atmosphere and animal biology. In November 2014, three members of the expedition will stay on board the ISS, joined by Russian, American, and Italian crew, as Expedition 42.
