Spacewalkers Drew Feustel and Greg Chamitoff are moving on to the next major task of today’s spacewalk.
Greg Chamitoff installed a Crew Equipment and Translation Aid cart light on the starboard-3 segment of the station’s truss. He used one bolt to secure the light to the cart and connect one power cable. Then they installed a cover on one face of the S3 solar alpha rotary joint.
Chamitoff has recharged the oxygen levels in his suit, and the two are moving on to a task that will prepare for the work Feustel and Mike Fincke will perform on the mission’s second spacewalk: to top off the ammonia in the station’s port-6 photovoltaic thermal control system cooling loop. The loop has a slow ammonia leak.
They will start by installing a jumper cable that will eventually connect the cooling loops of the port-4 segment of the station’s truss to the port-3 segment, then venting nitrogen from the loops between the port-1 and port-5 segments. They also will vent nitrogen from the jumper that connects the ammonia reservoir they will use for the refill to port-6.
