Expedition 61 Flight Engineers Jessica Meir and Christina Koch of NASA are scheduled to begin a spacewalk outside of the International Space Station at 6:50 a.m. EST Monday, Jan. 20.
Live coverage of the spacewalk will begin at 5:30 a.m. on NASA Television and the agency’s website.
This is the second of two battery replacement spacewalks in five days to complete the upgrade of batteries that store and distribute power generated by the station’s solar arrays on the station’s port truss. Meir and Koch will replace nickel-hydrogen batteries with newer, more powerful lithium-ion batteries for the power channel on one pair of the station’s solar arrays.
The batteries were transported to the station in September aboard the Japanese H-II Transfer Vehicle. The spacewalking work continues the overall upgrade of the station’s power system that began with similar battery replacement during spacewalks in January 2017.
