Expedition 1 [SEP] Introduction
Expedition 1 was the first long-duration stay on the International Space Station (ISS). The three-person crew stayed aboard the station for 136 days, from November 2000 to March 2001. It was the beginning of an uninterrupted human presence on the station which continues as of 2020. Expedition 2, which also had three crew members, immediately followed Expedition 1. The official start of the expedition occurred when the crew docked to the station on 2 November 2000, aboard the Russian spacecraft Soyuz TM-31, which had launched two days earlier. During their mission, the Expedition 1 crew activated various systems on board the station, unpacked equipment that had been delivered, and hosted three visiting Space Shuttle crews and two uncrewed Russian Progress resupply vehicles.
