2 astronauts take 2nd spacewalk high above Earth - Jul 16th, 2013 - International
— Two space station astronauts are picking up where they left off last week outside their orbiting home.
American Christopher Cassidy and Italian Luca Parmitano ventured out of the International Space Station on Tuesday morning. It's their second spacewalk in just eight days.
The two will perform some more cable work and other maintenance chores 260 miles up. They'll also install equipment to make the 15-year-old space station more robust in case of future failures.
Parmitano, a former test pilot, became Italy's first spacewalker last Tuesday. He arrived at the space station 1½ months ago. Cassidy, a former Navy SEAL, is a longtime spacewalker. He's been on board since March.
The four other space station residents are monitoring the action from inside. They include one American and three Russians.
