The International Space Station (ISS) is an artificial satellite in low earth orbit where space crews from NASA (USA), Roscosmos (Russia), JAXA (Japan), CSA (Canada) and ESA (Europe). This is a collaborative effort between five countries, which began when its first component went into space in 1998. Since then, many spacecraft voyages have regularly transported instruments to the ISS.
The ISS is the longest continuous human presence in space, more than 21 years old and counting. However, it is not the first manned space station like Salyut, Almaz, Mir and Skylab.
Furthermore, the ISS is divided into two regions, the Russian Orbital Segment (ROS) and the United States Orbital Segment (USOS). ROS is where Russian cosmonauts work, while USOS is where space crews from the US, Japan, Canada and Europe work together.
The process of building the ISS
In the 80s, NASA planned to build a competitor to the existing Russian space stations, Salyut and Mir. The project called “Freedom” has seen other space agencies (such as ESA and JAXA) join as partners over the years. Finally, Russia also joined the project and named it the International Space Station.
NASA, ESA, Roscosmos and JAXA each produce their own modules for the space station. Initially, the first ISS module arrived from Roscosmos in the form of Zarya in November 1998. Following the addition of the Zvezda module in July 2000, the space station became more suitable for human habitation. .
Before long, as part of “Expedition 1,” a three-person space crew landed on the ISS as the first inhabitants in November 2000. Since then, more than 240 space travelers from 19 countries have visited this space station.
All that happens on the ISS
The ISS serves a variety of purposes including scientific research, educational programs, and testing spacecraft before interplanetary missions.
When it comes to science, work in various fields, from astronomy to medical science, is done at the space station. Whether it’s studying the behavior of microorganisms in space or trying to detect dark matter in the universe, ISS residents do a wide range of research work.
The ship’s crew also contributes to education by showing relevant demonstrations in space, performing student experiments in zero gravity, and more. Sometimes, recording music videos. first in space.
Finally, the most done work on the ISS is maintenance of the space station. This is the most important mission to help scientists continue other important work in orbit.
