Astronauts Take Third Spacewalk To Complete Tricky Cable Job At International Space Station
CAPE CANAVERAL, Fla. (AP) — 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. American astronauts Terry Virts and Butch Wilmore had 400 more feet of power and data cable, as well as two antennas, to install Sunday. They successfully routed 364 feet on their first two excursions, on Feb. 21 and last Wednesday.
NASA hasn’t conducted such a quick succession of spacewalks since its former shuttle days, and the amount of cable work is unprecedented. Even more spacewalks will be needed once new docking ports start arriving in June.
“Good luck, guys,” Italian astronaut Samantha Cristoforetti said from inside as the spacewalk got underway early.
Before approving Sunday’s spacewalk, engineers spent two days analyzing a water leak in Virts’ helmet that occurred at the end of Wednesday’s outing.
