A new video shows why life on the International Space Station (ISS) is not suited to people who suffer from claustrophobia. Shot by Russian cosmonaut Oleg Artemyev, the incredible footage takes viewers on a journey around one of the longest routes on the ISS. Artemyev starts the route inside the Japanese storage module, which is in the furthest corner of the space station, and finishes in the Russian part of the station. The journey involves squeezing through small tunnels that link the different modules that make up the ISS. The space station is currently home to two Russians, three Americans and one Japanese. It has been permanently staffed by rotating crews of astronauts and cosmonauts since November 2000.
