International Space Station mockup at Johnson Space Center in Houston, Texas. The space station is located in orbit around the Earth at an altitude of approximately 410 km (250 mi), a type of orbit usually termed low Earth orbit (the actual height varies over time by several kilometers due to atmospheric drag and reboosts).
The Boeing Starliner spacecraft is now scheduled to undock from the International Space Station and return to Earth on June 22, NASA said on Friday, giving more time to finalize planning for the ...
Ground track example from Heavens-Above.An observer in Sicily can see the International Space Station when it enters the circle at 9:26 p.m. The observer would see a bright object appear in the northwest, which would move across the sky to a point almost overhead, where it disappears from view, in the space of three minutes.
