U.S. Spacewalk 100 Will Install the Station's Seventh Solar Array

Two astronauts will install and deploy another roll-out solar array on the International Space Station, this one on the 2A electrical power channel. NASA astronaut Anil Menon and CSA astronaut Joshua Kutryk will exit the station's Quest airlock to do the work, on what the agency calls U.S. spacewalk 100. The array will be the seventh IROSA, and its purpose reaches past routine power needs: NASA says the additional electricity will support critical station operations, including the station's safe and controlled deorbit.
