The 20-foot Solar Array Powering the James Webb Space Telescope

  • Released Wednesday, May 15, 2019

The James Webb Space Telescope's 20-foot solar array will provide all the power the observatory needs, by converting sunlight into electricity. Webb's solar array is its first and most important deployment. The small yet effective array will release itself like an accordian to a straightened configuration shortly after launch. The power it creates will help operate the telescope's propulsion and communication subsystems, as well as its scientific instruments.
