On Nov. 6, 2015, NASA astronauts Scott Kelly and Kjell Lindgren spent 7 hours and 48 minutes working outside the International Space Station on the 190th spacewalk in support of station assembly and maintenance. The astronauts restored the port truss (P6) ammonia cooling system to its original configuration, the main task for the spacewalk. They also returned ammonia to the desired levels in both the prime and back-up systems. The spacewalk was the second for both astronauts. Crew members have now spent a total of 1,192 hours and 4 minutes working outside the orbital laboratory.

At about an hour after the 6:22 a.m. EST start of the spacewalk, astronaut Kjell Lindgren took this photograph of Scott Kelly at work, with the station's solar arrays visible in the background.
