International Space Station
International Space Station Facts#
The International Space Station (ISS) is a modular space station in low Earth orbit. It is a joint project of five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).
History#
- The ISS project began in 1993 with the signing of an agreement between the United States and Russia.
- Construction of the ISS began in 1998 with the launch of the Zarya module.
- The first crew, Expedition 1, arrived at the ISS on November 2, 2000.
- The ISS has been continuously inhabited since then.
Size and Structure#
- The ISS is about the size of a football field.
- It has a mass of about 420,000 kilograms (926,000 pounds).
- The ISS is made up of 16 modules, including the Russian Segment, the US Segment, the Japanese Experiment Module, the European Columbus Module, and the Canadian Space Agency’s Canadarm2 robotic arm.
Orbit#
- The ISS orbits Earth at an altitude of about 400 kilometers (250 miles).
- It completes one orbit of Earth every 92 minutes.
- The ISS travels at a speed of about 27,600 kilometers per hour (17,150 miles per hour).
Crew#
- The ISS is typically crewed by six astronauts or cosmonauts.
- The crew is responsible for conducting experiments, maintaining the station, and performing spacewalks.
- The ISS has hosted astronauts and cosmonauts from 17 different countries.
Research#
- The ISS is a platform for conducting research in a variety of fields, including microgravity, space medicine, and Earth observation.
- The ISS has been used to conduct over 3,000 experiments.
- The results of ISS research have helped to improve our understanding of space and Earth, and have led to the development of new technologies.
Spacewalks#
- Spacewalks are performed by astronauts or cosmonauts to conduct maintenance and repairs on the ISS.
- Spacewalks are also used to conduct experiments and deploy satellites.
- Over 200 spacewalks have been performed from the ISS.
Future#
- The ISS is expected to continue to operate until at least 2024.
- There are plans to extend the ISS’s lifespan until 2030.
- The ISS will eventually be replaced by a new space station, the Lunar Gateway.
Interesting Facts#
- The ISS is the largest artificial object in orbit around Earth.
- The ISS is visible from Earth with the naked eye.
- The ISS has its own zip code: 20577.
- The ISS has a 3D printer that can be used to create tools and parts.
- The ISS has a greenhouse that grows vegetables and flowers.

The International Space Station (ISS) is a modular space station in low Earth orbit. It is a joint project of five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ISS serves as a microgravity research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, materials science, and meteorology.
