The James Webb Space Telescope Completes its Final Environmental Tests
Released on October 6, 2020
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 as the clamshell cover. The tent cover keep the telescope safe from contamination particles while it was being moved to the testing area. Next up for Webb, engineers will conduct the final sunshield deployment tests.
