The ISS will soon retire, But it's replacement will not likely come from NASA
The ISS had its first segments launched in 1998, And now it's starting to show its age.
Since the year 2000, The ISS has housed a group of rotating astronauts from 19 different countries. The Space station is used as a laboratory for science that can only be done in space.
NASA's space station is through to keep running until at least 2024 and NASA knows someday the space station will have to end its life.
