INSIDE The International Space Station - ISS

The International Space Station (ISS) is a marvel of modern engineering and international collaboration, orbiting Earth at an altitude of approximately 420 kilometers.
It is used as a microgravity laboratory for scientific research in numerous disciplines such as biology, physics, and astronomy. Astronauts inhabit a small yet well-organized space inside the ISS. The modules of the station consist of bedroom cabins or sleeping quarters, office cabins or workstations, and also kitchen sections that are fit for satisfying the daily requirements of man. They do experiments, exercise to prevent muscles shrinking, and look at beautiful sights on earth through window in International Space Station. Sustainability is critical in that the space centre has water and air recycle systems. The station revolves around the earth in approximately 90 minutes which implies a dawn and dusk daily event.
