Check out photos taken by two astronauts who ventured outside the International Space Station on Saturday, running more than 300 feet of wiring that will eventually be connected to new docking ports to receive commercial spaceships built by Boeing and SpaceX.

Watch a replay of the landing of Oleg Novitskiy and Thomas Pesquet inside the Soyuz MS-03 crew capsule on the Kazakh stepped Friday, ending their six-and-a-half month expedition on the International Space Station.
