You are looking at the sky and you see something moving: he is not an alien, nor one star o Superman. What is it then? It's just there International Space Station that passes over our heads every night. How do you say, have you never heard of this particular station? Do not worry because today, with us, you will discover everything there is to know about ISS (International Space Station) and you will become true experts.
The International Space Station: what is it?
La International Space Station is a space station in low earth orbit, dedicated to scientific research. A space station means a man-made construction intended for to make human beings live in Space. The ISS (International Space Station) is operated by five different space agencies: NASA (United States), RKA (Russia), ESA (Europe), JAXA (Japan and CSA-ASC (Canada).
This station covers an area greater than any other space station and, thanks to this, it is possible to see it with the naked eye from Earth. The International Space Station is in orbit around the Earth at a height of approximately 400 km ed it takes 90 minutes to complete a full circle around the Earth.
The ISS in fact travels at a speed of approx 27600 km/h it's complete 15,5 orbits per day: at the same time, it is kept in orbit at an altitude between 330 and 410 km above sea level.
As a construction capable of making humans live in space, the International Space Station since 2000 it hosts a crew of 2 to 7 astronauts. Over the years, the crew has undergone substitutions and there have also been occasions when various astronauts have returned to the ISS several times.
The structure of the ISS and its task
The International Space Station it is the largest space station in circulation, so much so that it is visible to the human eye on earth. Its structure is in fact characterized by 800 cubic meters of space habitable and is long 100 meters. On either side of the approximately 100 meter long main tube there are smaller spaces such as warehouses, laboratories, secondary rooms where the astronauts on duty live, study and observe the Earth.
The primary purpose of the International Space Station is to act as a laboratory for scientific research. As a long-term platform in a space environment, the ISS has made it possible to carry out lengthy experiments on the effects of almost total weightlessness on the evolution, development, growth and also on the internal processes of plants and animals.
The crew present on the station follows the experiments and continues their research every day, then communicating the results to the control center found on Earth.
Furthermore, the International Space Station allows the crew to carry out experiments on biotechnology chemistry medicine and much more, precisely because it is located in a completely different environment from that present on Earth.

How to observe the International Space Station?
The ISS is so large that it can be seen with the naked eye then you don't need special tools. However, if you want to make your experience even more professional and precise, the most suitable tool to observe it is a low magnification binoculars e a large field.
What is the best time to observe the station instead? Decidedly shortly after sunset e just before dawn.

Or, if you are observing it with the naked eye, you just need to sharpen your eyes and keep an eye on it carefully.
What else do we need to be able to see the ISS? Of a clockwise and various landmarks, such as start horizons and end of transit, but also fromheight reached by the spacecraft during the passage. Thanks to the site of the AstronomiAmo Association you can find everything you need: timetables, heights and much more to observe the satellite.
Instead, below we report the next steps of the ISS above the main Italian cities and various times in which to observe it:
- Pomegranate;
- Milan;
- Florence;
- Palermo;
- Cagliari.
If you want to follow the movements of the International Space Station in direct, directly from your smartphone or PC, you can consult the official website of NASA. Every day the space agency broadcasts the movements of the ISS live.
