NASA has expanded the power-generation capabilities on the International Space Station (ISS) by installing six new International Space Station Roll Out Solar Arrays (IROSAs) from 2021 to 2023. The lightweight, compact design of these solar arrays allows them to be launched as a cylinder and unfurl once installed in space. An additional set of IROSAs launched aboard the SpaceX 35th commercial resupply mission in 2023, further augmenting the ISS's capacity.
Together, eight IROSAs will increase the ISS's power by more than 160 kW.
What has been confirmed
The ISS orbits Earth at an altitude of about 250 miles, relying on solar power for crucial functions such as life support, operational activities, and scientific research. The new IROSAs, tested first in a technology demonstration on the ISS in 2017, are confirmed to add roughly 28 kilowatts each. With the installation of eight IROSAs, NASA expects an increase of over 160 kilowatts in total power for the station.Why it matters
The enhanced power supply is essential for supporting the growing scope of scientific research and daily operations on the ISS. For the US commercial aviation industry, maintaining and advancing the technology aboard the ISS continues to drive innovation, including developments that can benefit sectors like those focusing on next-generation sustainable energy solutions.FlyMarshall context
The advancements in the ISS’s solar power systems echo the aviation industry's own trending toward more efficient and sustainable power sources. Aircraft manufacturers and airlines are continually exploring ways to optimize fuel use and lower emissions, drawing parallels to space agencies' quests for efficiency and sustainability in space operations.What happens next
NASA plans to continue utilizing advanced technology to enhance the ISS's capabilities. With the new solar arrays installed, ongoing research and operations aboard the ISS can proceed with reduced concerns about power limitations. Further developments in this area are anticipated as NASA requests and plans additional IROSAs to sustain and expand ISS functions.Continue reading
