Content overview: “NASA Roll Out Solar Arrays Boost International Space Station Power Supply for Research and”. From 250 miles above Earth, the International Space Station relies on solar energy to power life support, daily operations, and hundreds of research investigations that benefit life on Earth and prepare humans for deep space exploration. Over the past five years, NASA has augmented the station’s power system with new Roll Out Solar Arrays, known as ROSAs, to ensure a robust and reliable energy supply. These advanced, flexible solar panels are more efficient and lighter than traditional rigid arrays, and they are being installed during spacewalks by astronauts.
The upgrades are critical because the station’s original solar arrays have degraded over time, reducing their power output. With increased power, the ISS can support more scientific experiments, technology demonstrations, and commercial activities in low Earth orbit.
