1 inch pin. Expedition 35 is the 35th long-duration mission to the International Space Station (ISS). The expedition will start in March 2013, when the Expedition 34 crew departs from the ISS. This will mark the first time a Canadian astronaut - Colonel Chris Hadfield - will be in command of the station. Expedition 35 will also be 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.
