NASA astronauts Anil Menon, Jessica Meir undertake spacewalk to upgrade space stationNASA astronauts Anil Menon and Jessica Meir completed a six-hour spacewalk outside the International Space Station, installing hardware for future roll-out solar arrays. Menon and Meir exited the Quest airlock and carried out structural upgrades on the exterior of the orbital laboratory during the six-hour, 27-minute spacewalk. Since 2021, astronauts on prior spacewalks have deployed six of the International Space Station Roll-Out Solar Array (IROSA) assemblies, leaving now just two awaiting delivery to the station later this year. This was the first of the three spacewalks for the space station’s Expedition 75 crew this month. The antenna is a critical communication system NASA uses to transmit data and high-speed communication between the Mission Control Centre in Houston and the space station.
