In April 2001, Hadfield served as mission specialist 1 on STS-100, International Space Station (ISS) assembly Flight 6A. The crew of [[Space Shuttle Endeavour|Space Shuttle ''Endeavour'']] delivered and installed [[Canadarm2]], the new Canadian-built robotic arm, as well as the Italian-made resupply module ''Raffaello''. During the 11-day flight, Hadfield performed two spacewalks, which made him the first Canadian to ever leave a spacecraft and float freely in space. During his first spacewalk Hadfield experienced severe eye irritation due to the anti-fog solution used to polish his spacesuit visor, temporarily blinding him and forcing him to vent oxygen into space. In total, Hadfield spent 14 hours, 50 minutes outside, travelling 10 times around the world during his spacewalk.<ref name="csabio" /><ref name="Hadfield 6">''An Astronaut's Guide to Life on Earth'' (Hadfield), pp. 86–96.</ref>
