On Aug. 6, NASA astronauts Jessica Meir and Anil Menon concluded a 6-hour, 27-minute spacewalk outside the International Space Station. Meir and Menon successfully completed their primary objective of preparing the 3B power channel for the future installation of a roll out solar array. Toward the end of the spacewalk, a carbon dioxide sensor on Menon’s spacesuit indicated an unexpected data reading. Menon reported no other issues during the spacewalk.
