See How Astronauts Improve the ISS Power System

Astronauts continue to modernize the ISS energy system - astronauts have already exited several times

outside the station. Over the next few days, researchers will be seen going into space to install equipment in preparation for the launch of a new solar array.

NASA Astronaut Mark Wande Hai and RepresentativeJapanese space agency JAXA Akihiko Hoshide will perform spacewalk. They will work on preparing the 4A power channel by installing a support bracket for the new solar array, the International Space Station Roll-Out Solar Arrays (iROSA).

Two of these arrays have already been installed - this output will be the third of the six required. The array will power several parts of the station, including the laboratory, Harmony module and Columbus.

The current solar panels were originallyare designed for 15 years, but some of them have been in operation for more than 20 years. Although the arrays are still functional, their effectiveness diminishes over time. Thanks to this and advances in technology, the new batteries will provide more energy than the old ones.
