EVA Officer Sandy Fletcher narrates an animation showing Expedition 61 Flight Engineers Jessica Meir and Christina Koch of NASA teaming up for their second spacewalk together. They venture outside the Quest airlock of the International Space Station for a spacewalk to continue the replacement of aging nickel-hydrogen batteries with new lithium-ion batteries on the port truss of the orbital outpost. The spacewalk is the third in a series of four spacewalks to upgrade the station’s power systems on the port truss that began with two days of work outside the station last October. It is the 225th spacewalk in support of space station assembly and maintenance, the second spacewalk in Meir’s career and the fifth for Koch.
