![]() The International Space Station project is a joint project between Canada, Russia, Europe, Japan, and the United States. The ISS is visible in over 95% of the inhabited lands on the planet, but it cannot be seen from the extreme southern and northern latitudes. NASA launched their "Spot the Station" service in 2012 which informs people via email or texts when the ISS will pass above their towns. These applications use the observer’s latitude and longitude and the orbital data to indicate when the space station will be visible. Numerous tools and smartphone applications that can tell you when the ISS will be passing through your area are available. Just like numerous satellites, the ISS also produces flares that are about 16 times brighter than Venus. Due to its size, the ISS is the brightest structure in the night sky after the moon, and it can be seen even in urban centers where the night sky is affected by light pollution. The ISS completes 15.5 orbits around the earth per day. The ISS takes about 10 minutes to travel from one horizon to the other therefore, it’s only visible during a fraction of that time since it moves into and out of the shadow of the planet. The ISS travels at a constant distance of about 250 miles from the earth’s surface. ![]() It can also be seen during the day, although with a great deal of difficulty. The space station is visible to the naked eye right before sunrise and some few hours after sunset. The ISS is seen as a slow-moving large white dot that passes quickly across the sky without changing its direction. Interestingly, the International Space Station can be seen with the naked eye. The ISS is composed of solar arrays, robotic arms, experiment bays, docking ports, radiators, structure trusses, and pressurized habitation modules. The United States has sent 143 people, followed by Russia with 46, Japan with 8, Canada with 7, and Italy with 5 people among others. About 236 people from 18 nations had visited the ISS by March 14, 2019. The first long-term inhabitants of the ISS arrived in November 2000. It is the biggest single structure ever launched to space by human beings whose main construction of the ISS was done between 19. The ISS (International Space Station) is an inhabitable artificial satellite or space-station in the LEO (low-earth-orbit).
