JWST Secondary Mirror Deployment

  • Released Thursday, April 14, 2016

The sole secondary mirror that will fly aboard NASA's James Webb Space Telescope was deployed at NASA's Goddard Space Flight Center in Greenbelt, Maryland, on March 24, 2016.

The Webb telescope uses many mirrors to direct incoming light into the telescope's instruments. The secondary mirror is called the secondary mirror because it is the second surface the light from the cosmos hits on its route into the telescope.
