The International Space Station celebrates its 10th birthday a decade of constant service. It is the longest period of continuous human habitation outside the atmosphere of the Earth. The first permanent crew reached the International Space Station on November 2, 2000. It is arguably humanity's most ambitious engineering project to date, a mixture of science, technology and political cooperation between former sworn enemies. In the 10 years since, the ISS has expanded to the size of a football field, and received 200 visitors. Now the station is nearly complete, but the jury on what it has achieved is still out. The ISS is a breakthrough of cooperation, said Yury Gidzenko from ISS Expedition 1. Before, there were separate space agencies. Now they work together. It is a leap forward.
