Video: Narrated preview of Jan. 13 spacewalk

Shane Kimbrough and Peggy Whitson, setting a new record as the world’s most experienced female spacewalker, floated outside the International Space Station Thursday and continued work to set up a second docking port for U.S. crew ferry ships. They also installed an upgraded computer relay box and protective shielding before calling it a day.

Clad in pressurized spacesuits, Russian cosmonauts Oleg Kononenko and Sergey Prokopyev used knives and scissors to slice through insulation and a debris shield on a Soyuz spaceship set to return to Earth next week, finally reaching the capsule’s metallic hull to examine the site of an air leak plugged in August.

Picking up where they left off last week, two space station astronauts ventured back outside the outpost Wednesday to continue the replacement of aging batteries in the lab’s solar power system. Two more spacewalks later this month should complete the multi-year project.
