ISS Expedition 66 Crew Perform Spacewalk

Sputnik goes live as the International Space Station Expedition 66 performs a spacewalk, designated US EVA 80, on Wednesday, 23 March.

NASA astronauts Kayla Barron and Raja Chari are expected to install hoses on a Radiator Beam Valve Module that routes ammonia through the station’s heat-rejecting radiators to keep systems at the proper temperature. The astronauts will also install a power and data cable on the Columbus module’s Bartolomeo science platform, replace an external camera on the station’s truss, and conduct other upgrades to the station's hardware.
