Expedition 46
Russians carry out spacewalk
Two veteran cosmonauts ventured outside the International Space Station Wednesday, swapped out materials science space exposure samples, installed handrails needed for future spacewalks and tested an applicator and thin-film coatings that could prove useful reconditioning aged or damaged hull panels.

Space station commander Scott Kelly and newly-arrived flight engineer Tim Kopra ventured outside the lab complex Monday and freed up a stalled robot arm-carrying transporter so it could be moved to a nearby anchor point and locked down, clearing the way for a Russian Progress supply ship to dock Wednesday.
