NASA astronauts Robert Behnken and Chris Cassidy have begun the final planned spacewalk during their mission at the International Space Station.
The spacewalkers switched their spacesuits to battery power at 7:12 a.m. EDT to begin the spacewalk, which is expected to last between six and seven hours.
The pair will be working on several tasks to upgrade systems and prepare for future station upgrades. Behnken and Cassidy will remove handling aids from two locations at the base of station solar arrays, prepare the outside of the Tranquility module for the arrival later this year of the Nanoracks commercial airlock, route ethernet cables, and remove a lens filter cover from an external camera.
