An arriving space shuttle crewmember snapped this photo of the space station Dec. 2, 2000, one month after the arrival of Expedition One.This photo of the station was taken by a crewmember aboard STS-104 in July 2001.

During the first year of continuous human presence aboard the International Space Station, the outpost became the largest, most sophisticated and most powerful spacecraft ever built. The station grew from a 70-ton, efficiency apartment-sized foothold in orbit to a space laboratory of unprecedented capability, a 150-ton orbiting complex with more volume than a three-bedroom house.

The following structures and modules were added to the space station between Nov. 2000 and Nov. 2001:
