The International Space Stations (ISS) is one of the greatest human and technological achievements in our history. Space agencies from the United States, Russia, Europe, Japan and Canada have come together for a common goal in the name of science and education. It is a symbol of technological excellence and a testament to what we can achieve through collaboration and teamwork. Here are 10 things you may not have known about the International Space Station.

5. The ISS is operated by Expedition crews of six astronauts and cosmonauts, with the station programme maintaining an uninterrupted human presence in space since the launch of Expedition 1 on 31 October 2000, a total of 10 years and 105 days. The programme thus holds the current record for the longest uninterrupted human presence in space, surpassing the previous record of 3,644 days, set aboard Mir.
