Two NASA astronauts have completed 6.5-hour spacewalk to continue the process of upgrading the space station’s power systems. The spacewalk kicked off a busy period of upcoming operations amid the continued uncertainty over the future of Russian co-operation on the ISS.
The Extravehicular Activity (EVA, or spacewalk) – US EVA-79 – was performed by astronauts Kayla Barron and Raja Chari and was second spacewalk at the station this year and the 247th EVA for construction, operation, and maintenance of the International Space Station (ISS) overall.
