Technicians install sun layers on the James Webb space telescope. They help resist shaking during lifting. The sound created by launching a rocket creates extreme vibrations that can adversely affect the operation of a satellite or an observatory. Therefore, engineers conduct a spaceship through simulations to test its performance.
The picture shows how technicians delicately examine the installed James Webb sun protection membranes (NASA) on the front side of the spacecraft. Acoustic tests show that the device has the necessary strength and stability for survival in a harsh space flight. Shields protect the observatory from the hot solar (230 degrees Fahrenheit) and cold spatial (-400 degrees Fahrenheit) side. James Webb will become a world space science observatory and will tackle the mysteries of our system, study distant stars and their worlds, and also help answer the question about the origin of the Universe.
