Nasa webb telescope final12/28/2023 ![]() During the tests nearly 600 individual channels of motion data were carefully observed and recorded. Technicians then carefully guided it to a nearby acoustic testing chamber where it was intentionally blasted by sound pressure levels above 140 decibels, with a spectrum tuned to the specific signature of the Ariane 5 rocket it will ride to space. Testing began by first encapsulating the entire telescope in a mobile clean room built to shield it from the outside world. The multinational group of individuals responsible for the execution of the acoustic and vibration test is composed of an outstanding and dedicated group of folks who are typical of the entire Webb team,” said Bill Ochs, Webb project manager for NASA Goddard Space Flight Center in Greenbelt, Maryland. Environmental testing demonstrates Webb’s ability to survive the rocket ride to space, which is the most violent portion of its trip to orbit approximately a million miles from earth. “The successful completion of our observatory environmental tests represent a monumental milestone in the march to launch. The next environment Webb will experience is space. Completed in two separate facilities within Northrop Grumman’s Space Park in Redondo Beach, California, these tests represent Webb’s final two, in a long series of environmental tests before Webb is shipped to French Guiana for launch. Though each component of the telescope has been rigorously tested during development, demonstrating that the assembled flight hardware is able to safely pass through a simulated launch environment is a significant achievement for the mission.
