This is the transport vehicle for the James Webb Space Telescope during the now completed acoustical and vibration testing phases. The transport vehicle includes a mobile clean-room and having worked in a clean-room I can tell you that’s not a small feat by itself.

The testing was a success because it did find an issue which was resolved. The testing process is described rater well in the following press release from NASA ( Credits: NASA’s Goddard Space Flight Center/Chris Gunn) :

NASA’s James Webb Space Telescope has successfully passed another series of critical testing milestones on its march to the launch pad.

In recent acoustic and sine vibration tests, technicians and engineers exposed Webb’s spacecraft element to brutal dynamic mechanical environmental conditions to ensure it will endure the rigors of a rocket launch to space.

During liftoff, rockets generate extremely powerful vibrations and energetic sound waves that bounce off the ground and nearby buildings and impact the rocket as it makes its way skyward. Technicians and engineers aim to protect Webb from these intense sound waves and vibrations.

To simulate these conditions, flight components are intentionally punished with a long litany of tests throughout different facilities to identify potential ...
