Kelly and Lindgren will take a second walk outside the space station on Friday, Nov. 6 to complete additional maintenance tasks to the space station.  

The two spacewalks flank two significant ISS milestones:  On October 29 Kelly becomes the U.S. astronaut who has lived in space the longest during a single U.S. spaceflight and November 2 marks the 15th year of a continuous human presence in space.
