Expedition 50 astronauts Shane Kimbrough and Thomas Pesquet are ready for their mission’s second spacewalk that starts Friday at 7 a.m. EST. The duo will wrap up power maintenance work to connect new lithium-ion batteries and install adapter plates. Kimbrough and NASA astronaut Peggy Whitson started that work last Friday during a six-hour, 32-minute spacewalk. Both spacewalks complement the ongoing robotics work that started at the end of December. Ground controllers have been remotely-operating the Canadarm2 robotic arm and Dextre robotic hand to remove and stow the old nickel-hydrogen batteries and the install the new batteries.
