This whole process was performed under stringent security and cleanliness guidelines, as it was among the most fragile operations throughout the entire launch campaign for Webb.

A shower curtain about 12 m high and 8 m in diameter was set up in between two platforms, to produce a closed-off space around Webb to prevent any contamination.

Webb will be the largest, most powerful telescope ever released into area. As part of a global collaboration contract, ESA is supplying the telescopes launch service using the Ariane 5 launch automobile. Working with partners, ESA was responsible for the development and credentials of Ariane 5 adjustments for the Webb mission and for the procurement of the launch service by Arianespace.

The next action is to encapsulate Webb inside Ariane 5s specifically adjusted fairing.
