Follow-Up: U.S. Spacewalk 100 Completed: Two Astronauts Install Seventh Roll-Out Solar Array in 7 Hours 11 Minutes, Station Power to Rise to About 215 Kilowatts
NASA reported on October 29 that U.S. spacewalk 100 has been completed: NASA astronaut Anil Menon and Canadian Space Agency (CSA) astronaut Joshua Kutryk concluded their spacewalk outside the International Space Station at 3:08 p.m. EDT, after 7 hours and 11 minutes. GSM previewed the mission on October 26.
During the spacewalk, Menon and Kutryk installed and deployed an International Space Station Roll-Out Solar Array (iROSA) on the station's 2A electrical power channel. The array is the seventh iROSA installed on the station and will provide additional power to support critical operations, including a safe and controlled deorbit.
The pair also completed several get-ahead tasks to prepare for a planned spacewalk on Thursday, November 5, when the eighth and final iROSA will be installed on the 3B power channel. NASA will provide live coverage beginning at 6:45 a.m. EDT.
Following the November 5 spacewalk, the roll-out solar arrays will be fully installed, completing the station's power system augmentation. Together, the eight arrays will increase available power by up to 30 percent, boosting the station's power generation capacity from 160 kilowatts to approximately 215 kilowatts.
U.S. spacewalk 100 was Menon's fourth spacewalk and Kutryk's first. It was also the 285th spacewalk in support of space station assembly, maintenance and upgrades, according to NASA.
