Description

The James Webb Space Telescope's "pathfinder telescope," or “Pathfinder” completed its second super-cold optical test that resulted in the first checkout of specialized optical test equipment designed to illuminate the telescope’s optics through to the instrument focal planes, and the procedures used to operate this test equipment.

This image shows engineers inspecting the Pathfinder after this test in Chamber A at NASA's Johnson Space Center.
