International Space Station Quiz – Home in Orbit

The International Space Station is a laboratory and home orbiting Earth about 400 kilometers up. Built from 1998 by the United States, Russia, Europe, Japan and Canada, it has been continuously occupied since November 2000.

The ISS is about the size of a football field and travels at 28,000 km/h, circling Earth every 90 minutes. Astronauts conduct experiments in biology, medicine, physics and materials, and study how the human body changes in microgravity.

Crews arrive on spacecraft like Soyuz and SpaceX Crew Dragon, and cargo ships bring supplies. The ISS is planned to retire around 2030, with commercial stations expected to continue research in low Earth orbit.
