<p>With the completion of its latest series of milestone tests, NASA’s James Webb Space Telescope has now survived all of the harsh conditions associated with a rocket launch to space. 
</p><p>Webb’s recent tests have validated that the fully assembled observatory will endure the deafening noise, and the jarring shakes, rattles and vibrations of liftoff. Known as “acoustic” and “sine-vibration” testing, NASA has worked carefully with its international partners to match Webb’s testing environment precisely to what Webb will experience both on launch day, and when operating in orbit.
</p><p>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. 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.
</p><p>The next environment Webb will experience is space.
