CAPE CANAVERAL, Fla. (July 9, 2013)--Two spacewalking astronauts were tackling a backlog of outdoor work Tuesday at the International Space Station.
American Christopher Cassidy and Italian Luca Parmitano ventured out Tuesday morning on the first spacewalk for Italy, a major contributor to the orbiting lab.
The spacewalkers had a hodgepodge of maintenance chores that included replacing failed communication equipment, removing a bad camera and collecting science experiments.
They also performed prep work for a new Russian lab that’s due to arrive in December.
They’ll wrap up the work on a second spacewalk, next Tuesday.
NASA says the tasks have been piling up over the past couple of years.
Managers wanted to wait until the to-do list was long before committing to the time-consuming spacewalks.
