Expedition 35 was the 35th long-duration mission to the International Space Station (ISS). The expedition started 13 March 2013, and marked the first time a Canadian astronaut – Colonel Chris Hadfield – was in command of the station. Expedition 35 was also only the second time an ISS crew is led by neither a NASA astronaut, nor a Roscosmos cosmonaut, after Expedition 21 in 2009, when ESA astronaut Frank De Winne was in command. The expedition lasted two months.

The first Canadian to perform extravehicular activity in outer space, he has flown two Space Shuttle missions and also served as commander of the International Space Station (ISS). Prior to his career as an astronaut, he served in the Canadian Armed Forces for 25 years as an Air Command fighter pilot.
