After 50 years -- the cosmonaut Yuri Gagarin's maiden voyage set off an international space race that defined an era, and while only Gagarin knew exactly what it was like to be the first man in space. Documentarian Christopher Riley gave us a glimpse of what the world might have looked like from the porthole of Vostok 1. First Orbit is a mashup of sorts that features original audio recordings from Gagarin's flight, coupled with footage taken by Italian astronaut Paolo Nespoli from aboard the International Space Station.
