Webb's secondary mirror is fully deployed. Webb's secondary mirror had to deploy in microgravity, and in extremely cold temperatures, and it ultimately had to work the first time without error. It also had to deploy, position, and lock itself into place to a tolerance of about one and a half millimeters, and then it has to stay extremely stable while the telescope points to different places in the sky – and that’s all for a secondary mirror support structure that is over 7 meters in length. Webb's secondary mirror is at the end of the Secondary Mirror Support Structure (SMSS). The secondary mirror plays an important role in reflecting the light from the primary mirror to where the instruments sit, behind the primary mirror.
