JWST Aft-Optics System (AOS) Installed at GSFC

Engineers installed the Aft-Optics System (AOS) into NASA's James Webb Space Telescope at Godddard Space Flight Center on March 5, 2016.

The AOS is a precision beryllium rectangular optical bench that houses the tertiary and the fine steering mirror installed at the center of Webb's primary mirror. The AOS is surrounded by a shroud that eliminates stray light, and two large radiator panels that keep the assembly cold. This subsystem collects and focuses the light from the secondary mirror and feeds it into the science instruments.
