On Nov. 2, 2000, the first three people to inhabit the International Space Station arrived at the outpost in their Soyuz TM-31 spacecraft.
NASA astronaut William Sheperd and Russian cosmonauts Yuri Gidzenko and Sergei Krikalev docked to the aft port of the Zvezda service module. At the time, the ISS consisted of only three pressurized modules.
Sheperd, Krikalev and Gidzenko spent four-and-a-half months living aboard ISS. During that time a single Progress cargo ship and three space shuttles visited the complex.
The first two shuttles, Endeavour and Atlantis, each brought up pieces of the outpost. Endeavour brought the P6 truss in December 2000 while Atlantis brought the first station laboratory, Destiny, in February 2001.
Discovery launched in March 2001 and brought up supplies for the outpost. Additionally, the spacecraft ferried three new crew members to the outpost: Russian cosmonaut Yury Usachev and NASA astronauts James Voss and Susan Helms. They would form Expedition 2.
The Expedition 1 crew would return home in Discovery having completed 141 days in orbit. Today, the International Space Station is currently hosting Expedition 50. The outpost has since been completed and six people regularly inhabit it.
Since Nov. 2, 2000, there has always been at least two people living in orbit – a record time of uninterrupted occupation of space.
