On April 08, 2019, American astronaut Anne McClain and Canadian astronaut David Saint-Jacques performed a spacewalk to continue the ongoing program to replace the station’s aging batteries and upgrade power systems. The main task was to establish a redundant path of power to the Canadian-built robotic arm, known as “Canadarm-2”. The EVA (extravehicular activity) lasted 6 hours and 15 minutes. This was the first spacewalk for David Saint-Jacques and the 2nd for Anne McClain.
