The James Webb Space Telescope Completes its Final Environmental Tests

The fully assembled James Webb Space Telescope has completed its environmental tests at Northrop Grumman in Redondo Beach, CA. The environmental tests are a combination of acoustic and sine vibration tests. These tests simulate the conditions the telescope will encounter during launch. Completing these tests ensures that the telescope will survive launch. Prior to testing, engineers lifted the telescope onto the transport fixture and covered the telescope with a protective tent cover, sometimes referred to
