Spacewalking astronauts ventured out for the third time in just over a week Sunday to complete an extensive, tricky cable job at the International Space Station.
The advance work — involving nearly 800 feet of cable over three spacewalks — is needed for new crew capsules commissioned by NASA. A pair of docking ports will fly up later this year, followed by the capsules themselves, with astronauts aboard, in 2017.
