During U.S. spacewalk 100, NASA astronaut Anil Menon and CSA (Canadian Space Agency) astronaut Joshua Kutryk will exit the station’s Quest airlock to install and deploy an International Space Station Roll-Out Solar Array (IROSA) on the 2A electrical power channel. The solar array will be the seventh IROSA and will provide additional power to support critical station operations, including its safe and controlled deorbit.

During U.S. spacewalk 101, Menon and Kutryk will install and deploy the eighth and final IROSA on the 3B channel of the space station, completing the power augmentation upgrades.

The final two roll-out solar arrays will complete the space station’s power system augmentation. Together, the eight roll-out arrays will increase available power by up to 30%, boosting the station’s electric power generation capacity from 160 kilowatts to approximately 215 kilowatts.

NASA will share additional coverage details about U.S. spacewalks 100 and 101 closer to each operation on the agency’s live events web page and the space station blog . The spacewalks will be the 285th and 286th conducted in support of space station assembly, maintenance, and upgrades.
