See graphic below for the locations of the various iROSA arrays on the ISS. Truss 2A is being worked on today.

Each iROSA array produces more than 20 kW of electricity; the 8 arrays will eventually generate 160 kW of augmented power during orbital daytime. In addition, the partially uncovered original arrays will continue to generate ~65 kW of power.

iROSA on 3B will be deployed on Nov 5.

NASA astronaut Anil Menon and CSA (Canadian Space Agency) astronaut Joshua Kutryk successfully installed and deployed the 7th Roll-Out Solar Array (IROSA) on the International Space Station during a 7-hour, 11-minute spacewalk.

The last one will be installed on Thu Nov 5.

Who else wants to sign up for this job?
