Spacewalkers Begin Work to Upgrade Power Systems
Two NASA astronauts switched their spacesuits to battery power this morning at 6:35 a.m. EST Expedition 61 Flight Engineers Christina Koch and Jessica Meir are venturing out into the vacuum of space for about six-and-a-half hours to finish replacing nickel-hydrogen batteries with new lithium-ion batteries that store and distribute power generated by the station’s solar arrays on the station’s port truss. The lithium-ion batteries provide an improved power capacity for operations with a lighter mass and a smaller volume than the nickel-hydrogen batteries.
