NASA astronauts Scott Kelly and Kjell Lindgren are looking ahead to Friday morning’s spacewalk to return the port truss cooling system back to its original configuration after repair work completed in 2012. Japanese astronaut Kimiya Yui will assist the spacewalkers before they get out the door and coordinate their activities from inside the International Space Station.
Today, the trio reviewed the cooling system servicing spacewalk procedures and organized their tools. Kelly and Lindgren will work with ammonia fluid cables and tanks during the spacewalk scheduled for Friday at 7:10 a.m. EST. Yui joined the duo and trained for the possibility their spacesuits may come in contact with ammonia coolant flakes.
