NASA Astronauts Spacewalk Outside the International Space Station on Jan. 15, 2020

On Wednesday, Jan. 15, NASA astronauts Jessica Meir and Christina Koch will step outside of the International Space Station into the vacuum of space together. The duo will replace old nickel-hydrogen batteries with newer, more powerful lithium-ion batteries to continue upgrading station power systems on the Port-6 truss structure. The spacewalk is scheduled to begin at 6:50 a.m. EST and last about six-and-a-half hours.
