|Assembling a World-Class
Phases Two and Three
Phase II, construction in orbit, begins with the first station elements to be launched in 1998-Zarya in November and Unity in December. Next, the first wholly Russian contribution, a component called the Service Module, will be launched from Russia in 1999. It will provide the initial living quarters and life support systems.
After additional assembly and supply flights, a three-person crew will be launched aboard a Russian Soyuz capsule in January 2000. From that point on, the station will be permanently inhabited. Phase II of the station's assembly will be completed, at which point the station will be ready for scientific research work to begin in a U.S. laboratory module.
Phase III of assembly will see the International Space Station progress gradually to completion, equipped with laboratory modules supplied by the United States, Japan, Europe and Russia and with a robot arm supplied by Canada. A crew of up to seven members will be able to live and work aboard the station.
