    The ISS was launched from Earth, in pieces but still it’s of Earth origin, and will eventually fall back to Earth. It’s inside the Earth’s atmosphere and experiences drag. It’s orbit has to be adjusted and maintained.

      Yes, that’s all true, but none of that describes its free-fall trajectory. Drag causes it to deviate from free-fall very slightly, and it definitely wasn’t in free-fall when the pieces were launched from Earth
