Video: Narrated preview of Jan. 6 spacewalk

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.

Four days after a picture-perfect blastoff from southern Japan, a cargo-carrying supply freighter arrived at the International Space Station on Tuesday with 4.5 tons of equipment, food, clothing and experiments.

An unexpected, quickly-planned spacewalk is on tap Monday to troubleshoot a problem preventing the International Space Station’s robot arm transporter from reaching a worksite where it can be locked down, a requirement before a Russian Progress cargo ship can dock later in the week.
