The astronauts of Expedition 61 have tackled some historic spacewalks during their mission to the International Space Station. Not only did two NASA astronauts conduct the first all-woman spacewalk on Oct. 18, but two of their male compatriots completed some of the most challenging spacewalks in history to repair an ailing dark matter experiment known as the Alpha Magnetic Spectrometer. Click through this gallery for photos of the spacewalkers of Expedition 61 in action.
