NASA’s James Webb passes a huge test launched in October 2021.



Despite numerous delays, financial crises and technical challenges, NASA̵

7;s James Webb Space Telescope is almost ready.

Each individual component is fully built, assembled and integrated.

Strict pre-launch testing can increase our chances of Webb’s success.

The retracted telescope must survive severe launch conditions without suffering damage.

Then from its cosmic environment all components must be deployed correctly.

The primary mirror segments must be unfolded, aligned with a tolerance of 20 nanometers.

All 5 layers of sunscreen must develop without being caught, torn or torn.

Earlier testing for vulnerabilities that may occur during startup and deployment.

Subsequent structural adjustments and improvements were then applied.

On October 6, 2020, NASA and Northrop Grumman successfully completed Webb’s latest environmental stress test.

For several weeks, Webb was severely tested, experiencing harsher conditions than the actual launches.

It survives high-frequency acoustic pressures, including sounds in excess of 140 decibels.

The sinusoidal vibration test shook the spacecraft intensely, exceeding the vibrational stresses occurring in the rocket.

Unlike previous tests, each individual component survived, maintaining optimal performance.

Only tests for the implementation of a sunscreen and mirror, as well as a final evaluation of the systems, remain as stages before the start.

The web, aboard the Ariane 5, will launch in October 2021 from French Guiana.

With the completion of environmental tests, the universe is waiting.
