Since Yuri Gagarin became the first human to leave Earth in 1961, over 500 intrepid adventurers have made the journey into space. Today, astronauts and cosmonauts from around the world visit the International Space Station (ISS), which serves as a microgravity and space environment research laboratory. Life on the ISS is therefore far from easy; isolated space travellers must deal with the strange sensation of weightlessness and having very little access to fresh food.
