Astronauts Raja Chari & Matthias Maurer Spacewalk Outside the International Space Station

NASA astronaut Raja Chari and European Space Agency (ESA) astronaut Matthias Maurer are conducting a spacewalk on Wednesday, March 23 to install new hoses on the International Space Station’s Radiator Beam Valve Module, which helps regulate the station’s temperature. Chari and Maurer will also install a power and data cable on the station’s Bartolomeo science platform, replace an external camera, and conduct other upgrades to station hardware. Wednesday’s spacewalk is expected to begin around 8:50 a.m. EDT (12:50 UTC) and take about six-and-a-half hours. This spacewalk will be the second of Chari’s career and the first for Maurer.
