Conditions for seeing the station: the space station is visible because it reflects sunlight, the same reason we can see the Moon. However, unlike the Moon, the space station is not bright enough: it is only visible at dawn and dusk (when it is illuminated by the Sun but it is nighttime on Earth), and only when it is 40 degrees or more above the horizon.
-
What equipment do you need to see the station?: none, as it will appear to the naked eye as if it were a bright star or a moving plane, with the difference that it will move faster than a plane (planes fly at 900 km/hour and the space station does so at 28,000 km/hour).

When will it be visible in your city: check
this NASA link to find out when the Station will be visible from your location. Enter your city, tap on the icon, and click 'View sighting opportunities'.
-
How often can I see it from my location: this can vary from several times a week to just once in a whole month. In any case, the chances are few since the passage through your location has to coincide with sunrise or sunset, as well as being at a certain altitude.

Altitude: The International Space Station is actually very close to Earth, at an altitude of between 370 and 460 kilometres, depending on the orbit. For comparison, commercial aircraft fly at an altitude of 10-12 km, GPS satellites orbit at 20,000 km and the
Meteosat weather satellite orbits at 36,000 kilometres. The
Moon, on the other hand, is at an average distance of 384,402 km.

Year of launch of the first module: 1998
-
Creation of the ISS: The United States, Russia, Japan, Canada and several ESA Member States joined forces to build the Station.
-
Russia and China: Russia has announced that it will continue as a partner of the Station until 2028, when it plans to begin construction of its own. The first modules of the Russian station will be launched between 2027 and 2030. China, for its part,
began construction of its own in 2021.
-
Presence of astronauts: uninterrupted since 2000, over numerous
expeditions.
-
Circumnavigation of the Earth: it takes 90 minutes to complete one full orbit of the Earth (the
crew members currently present see 16 sunrises or sunsets each day).
-
Speed: 28.000 km/h
