On 2nd November, the ISS travelled its 1.5billionth mile, with six resident astronauts on board from across the globe. The International Space Station became the longest continuously inhabited spacecraft last month, beating the preivous record of 3,644 days held by the Russian Mir Space Station. Since the first crew left Kazakhstan on 31st October 2000 and docked with the station two days later, it has been inhabited by a crew, and continues to serve as a foothold into space for humanity.
