Armed with a knife, scissors and other cutting tools, cosmonauts Oleg Kononenko and Sergey Prokopyev went outside the International Space Station on Dec. 11 to slice into the thermal insulation of a Soyuz spaceship and inspect the site of a repaired air leak that briefly caused a minor drop in air pressure in the research outpost earlier this year.

Two astronauts floated outside the International Space Station Thursday and installed two new cameras on the front of the lab complex that will provide views of commercial crew ships during final approach and docking. The spacewalkers also replaced a faulty high-definition camera and closed a door that was jammed open on an external instrument.
