## Final Solar Array Installation
NASA astronauts completed the eighth and final ISS Roll-Out Solar Array on Nov 5, 2026.
## Spacewalk Details
The 6-hour-and-59-minute spacewalk began at 8:36 a.m. EST and ended at 3:35 p.m. EST.
## Team Members
NASA astronaut Anil Menon and Canadian Space Agency astronaut Joshua Kutryk performed the installation.
## Deployment Process
The team retrieved the 750-pound iROSA assembly from a temporary stowage platform and mounted it using Canadarm2.
## Power Issue
NASA astronaut Nichole Stilwell reported half the expected shunt current during the deployment process.
## Resolution
The astronauts waited for the station to enter Earth's shadow to inspect connectors and resolve the issue.
## Successful Deployment
The array unfurled to its full 63-foot length without motor assistance in about 10 minutes.
## Power Benefits
The new arrays provide 40% more power and half the size of previous arrays for the station's 26-year mission.
## Mission Context
The deployment supports the ISS through its retirement and controlled deorbit scheduled for late 2030.
## Key takeaway

NASA astronauts installed the eighth and final ISS solar array on Nov 5, 2026, boosting power output by 30% for the station's 26-year mission.
