History
The International Space Station (ISS) is a remarkable testament to international co- operation in space exploration, evolving from early concepts to a symbol of collabora- tive achievement. The groundwork for what would become the ISS was laid during the Cold War, as both the United States and the Soviet Union explored the possibilities of human habitation in space. Initial proposals for space stations emerged in the 1950s, reflecting the ambitions of both superpowers to create platforms that would facilitate long-duration missions and research[1][2].
The collaborative spirit gained momentum in the 1970s with the Apollo-Soyuz Test Project, marking the first docking of spacecraft from the two nations. This mission, considered a success, opened the door to further joint ventures, leading to more am- bitious plans, such as International Skylab and the Skylab-Salyut Space Laboratory concepts. However, these ideas were stifled by budget constraints and escalating Cold War tensions[2][16].
It was not until the late 1980s that the idea of a joint space station began to take form again. In 1998, the first module of the ISS was launched, signaling the beginning
of a new era of international collaboration. Over the years, the ISS has expanded through contributions from various countries, allowing a diverse group of astronauts and cosmonauts to inhabit and work aboard the station[3][1]. By November 2, 2000, a permanent human presence was established when astronauts Bill Shepherd, Yuri Gidzenko, and Sergei Krikalev arrived at the ISS, initiating continuous operations that would last for decades[3].
Since its inception, the ISS has hosted over 240 individuals from 19 different coun- tries, making it a cornerstone of space-age cosmopolitanism and scientific research in microgravity. The collaborative framework is upheld through various agreements and memoranda of understanding, defining the roles and responsibilities of the par- ticipating partners, which include NASA, Roscosmos, the European Space Agency, JAXA, and others[1][16][14].
