NASA's Webb Telescope Wrapped in a Mobile Clean Room

Some presents are just too big to put under a tree. What’s wrapped up in this picture, however, is NASA's James Webb Space Telescope, and the wrapping job is a special mobile clean room to ensure it remains pristine while moving from building to building.


The mobile clean room is, essentially, a giant sealed bag that is purged with clean, dry air injected from pressurized bottles though a flexible tube. A small leak is included in the design so that the container can maintain positive pressure by releasing clean air while blocking air inflow.


Once Webb launches in 2021, and is “opened” and functioning, Webb will be a present to scientists that helps them unwrap mysteries of the cosmos. It will bring countless discoveries to scientists and people around the world.
