Ten years ago today (July 20, 1998) the first piece of the International Space Station was launched into orbit, the Zarya module (built by Russia, financed by the US). It was lofted by a Russian Proton K booster from the Russian launch complex, the Baikonur Cosmodrome, located in Khazakstan. Two weeks later the first American piece, the Unity node, was launched aboard a Space Shuttle from Florida.
The ISS has been continuously inhabited since July, 2000, usually with a three person crew which is scheduled to increase to six in the first half of 2009.
