2. International Space Station Origin: The international space station project began as a cooperative agreement to build and operate a large orbital station for the benefit of the international participants Space Station Freedom was announced in 1983 as part of President Regan’s space exploration initiative International participants included (as major contributors): USA USA ESA ESA Japan Japan Italy Italy Brazil Brazil

3. Space Station Freedom – Dual Keel

4. Space Station Freedom - Baseline

5. Space Station Freedom Budget problems inside and outside of NASA reduced Space Station Freedom’s scale to the Phase 1 (Baseline) Initial hardware fabrication for SSF started by 1990, so the ISS design inherited many of the SSF features Initial hardware fabrication for SSF started by 1990, so the ISS design inherited many of the SSF features Main truss assembly retained Main truss assembly retained Solar arrays attached to each end of the truss remained Solar arrays attached to each end of the truss remained Modular research module concept was retained and based on Space Shuttle payload bay size limitations Modular research module concept was retained and based on Space Shuttle payload bay size limitations

6. International Space Station Collapse of the Soviet Union in 1991 presented both Russia and the U.S. with cooperative space opportunities The U.S. could benefit from Russia’s vast experience in space station operations to enhance its SSF project The U.S. could benefit from Russia’s vast experience in space station operations to enhance its SSF project Proposals were made in 1992/1993 to combine the U.S. and Russian space station efforts Proposals were made in 1992/1993 to combine the U.S. and Russian space station efforts Included the SSF international partners Included the SSF international partners

7. International Space Station Alpha These agreements were the birth of the International Space Station Alpha These agreements were the birth of the International Space Station Alpha Later renamed International Space Station Later renamed International Space Station

8. International Space Station Implementation of the partnership between the U.S. and Russia and the original SSF partners consisted of a 10-year assembly schedule divided into in three phases Phase One - Shuttle/Mir Flights Shuttle-Mir Program would provide flight experience to reduce International Space Station assembly and operations risks Phase Two - Human-Tended Capability Space station human-tended capability offered frequent, extended research lab access until permanent operations Phase Three - Permanent Habitation International Space Station begins permanent habitation and operations with Soyuz crew vehicles docked for emergency return
