The age of human spaceflight began 56 years ago when Yuri Gagarin launched into space aboard Vostok 1. The 27-year-old Gagarin’s flight lasted 108 minutes during which he completed one revolution of the Earth. Upon his return to Earth, Gagarin toured the world as a beloved Hero of the Soviet Union and praised the world over for his historic accomplishment.
Roughly every six weeks or so the ground track of the International Space Station matches up with that of Vostok 1′s at the same time of day that the historic mission flew. This allows astronauts on board the ISS to see the world almost exactly as Gagarin saw it.
In 2011, ESA astronaut Paolo Nespoli filmed the Earth during one of these orbits as part of a film called First Orbit, created by filmmaker Christopher Riley. Audio of Gagarin’s flight and his conversations with ground control are included in real time to simulate the cosmonaut’s historic journey.
