ISS astronauts install final iROSA solar panel to augment aging ISS power systems

Power Upgrade Program Completed on the International Space Station

The comprehensive energy infrastructure upgrade program conducted aboard the International Space Station (ISS) has reached completion. Astronauts successfully installed the final Roll-Out Solar Array (iROSA) solar panel, designed to augment and reinforce the station's aging power systems.

Boosting Aging Power Systems with iROSA Panels

This long-ongoing modernization effort aimed to significantly boost the space station's power generation capabilities. With the successful installation of the final iROSA panel, the electrical load on the station's original power channels—which have operated for years—is effectively relieved, optimizing total energy efficiency.

Impact on Future Scientific Operations

The upgraded power infrastructure ensures the uninterrupted operation of ongoing scientific experiments and life support systems aboard the ISS. Completing this critical upgrade project enables high-power-demand research to continue safely throughout the remainder of the station's operational lifecycle.
