  • In 2017 a series of power upgrades began to replace the nickel-hydrogen batteries with new lithium ion ones that have a 20-year lifetime. These spacewalks will mark the culmination of the upgrade process. NASA posted on Twitter an animation of how a battery swap in space looks like. 
  • For viewers to be able to identify the astronauts, Cassidy will be the one in a red striped suit and Behnken will wear a suit with no stripes.
