The International Space Station (ISS): Achievements and Future Prospects
The International Space Station (ISS) stands as a monumental achievement in human ingenuity and international cooperation. Orbiting Earth at an average altitude of 420 kilometers (about 261 miles), the ISS serves as a microgravity and space environment research laboratory where scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. Launched in 1998, the ISS has been continuously inhabited since November 2000, making it one of the longest human spaceflight missions in history.
Achievements and Discoveries of the ISS
