Space Station Freedom was a NASA project to construct a permanently crewed Earth-orbiting space station in the 1980s. Although approved by then-president Ronald Reagan and announced in the 1984 State of the Union address, Freedom was never constructed or completed as originally designed, and after several cutbacks, the project evolved into the International Space Station program. Space Station Freedom was a NASA project to construct a permanently crewed Earth-orbiting space station in the 1980s. Although approved by then-president Ronald Reagan and announced in the 1984 State of the Union address, Freedom was never constructed or completed as originally designed, and after several cutbacks, the project evolved into the International Space Station program. Space Station Freedom was a joint project between four participating space agencies: NASA (United States), JAXA (Japan), ESA (Europe), and CSA (Canada). As the Apollo program began to wind down in the late 1960s, there were numerous proposals for what should follow it. Of the many proposals, large and small, three major themes began to gain currency. Foremost among them was a crewed mission to Mars, using systems not unlike the ones used for Apollo. A permanent space station was also a major goal, both to help construct the large spacecraft needed for a Mars mission as well as to learn about long-term operations in space. Finally, almost as an afterthought, the idea of a 'space logistics vehicle' that could cheaply launch crews and cargo to that station appeared to make sense. In the early 1970s, Spiro Agnew took these general plans to President Nixon, who was battling with the deficit. When he presented the three concepts, Nixon told him to select one. After much debate, NASA selected the space logistics vehicle, which by this time was already known as the Space Shuttle. They argued that the Shuttle would so lower costs of launching cargo that it would make the construction of the station less expensive. From this point forward these plans were never seriously changed, in spite of dramatic changes to the funding environment and the complete redesign of the Shuttle concept. In the early 1980s, with the Space Shuttle completed, NASA proposed the creation of a large, permanently crewed space station, which then-NASA Administrator James M. Beggs called 'the next logical step' in space. In some ways it was meant to be the U.S. answer to the Soviet Mir. NASA plans called for the station, which was later dubbed Space Station Freedom, to function as an orbiting repair shop for satellites, an assembly point for spacecraft, an observation post for astronomers, a microgravity laboratory for scientists, and a microgravity factory for companies. Reagan announced plans to build Space Station Freedom in 1984, stating: 'We can follow our dreams to distant stars, living and working in space for peaceful economic and scientific gain.' The 1990 Space Exploration Initiative called for the construction of the Space Station Freedom. Following the presidential announcement, NASA began a set of studies to determine the potential uses for the space station, both in research and in industry, in the U.S. or overseas. This led to the creation of a database of thousands of possible missions and payloads; studies were also carried out with a view to supporting potential planetary missions, as well as those in low Earth orbit. Several Space Shuttle missions in the 1980s and early 1990s included spacewalks to demonstrate and test space station construction techniques. After the establishment of the initial baseline design, the project evolved extensively, growing in scope and cost.
