On March 15, NASA astronauts Raja Chari and Kayla Barron conducted a nearly seven-hour spacewalk on the International Space Station (ISS) to build and install an adapter bracket for the station’s new iROSA solar panels to be added on top of the station’s current solar panels. It allows them to use the same motors and power management system as the current panels, the oldest of which are pushing over a decade in space. 

Kayla was designated EV-1 and wore the spacesuit with red stripes and Raja was EV-2, wearing the plain spacesuit. This was her second spacewalk and his first. The two completed the adapter installation early and completed additional “get ahead” tasks, including loosening several bolts on equipment they will use on a spacewalk next week and inspecting the area around the Alpha Magnetic Spectrometer. This spacewalk, number US EV-79, marked 1,555 hours across 247 spacewalks on the ISS.
