Roman Space Telescope Solar Panels are Fully Installed

  • Released Thursday, July 10, 2025

On June 14 and 16, technicians installed solar panels onto NASA’s Nancy Grace Roman Space Telescope, one of the final steps in assembling the observatory. Collectively called the Solar Array Sun Shield, these panels will power and shade the observatory, enabling all the mission’s observations and helping keep the instruments cool.

The Solar Array Sun Shield is made up of six panels, each covered in solar cells. The two central panels will remain fixed to the outer barrel assembly (the observatory’s outer shell) while the other four will deploy once Roman is in space, swinging up to align with the center panels.

In this video, watch how the technicians carefully place each solar panel.
