ISS DIY Repairs

I spent several hours this morning watching Peggy Whitson and Shane Kimbrough change out the batteries on the International Space Station.
I found it totally mesmerizing to watch and listen as they worked through the process as a coordinated team.
These two astronauts in concert with the ground crew performed a virtuoso space ballet.
Quite beautiful to my eyes to say the least.
Peggy Whitson will become the  ISS Commander when Shane Kimbrough returns to Earth.
