On the WebbCams Today

On our Webbcams are views of the assembly stand and the James Webb Space Telescope flight "telescope structure" - this structure is essentially like the bones of the telescope. Starting in late November, the flight mirrors will be mounted to it via a robotic arm, which is usually visible at right. We expect the mirror to be fully assembled by spring.

One Webbcam 1, in the left back corner, you may see technicians staging the flight mirrors in prep for being lifted onto the assembly stand.

Our flight instrument module, a smaller black latticed structure, with silver and gold shapes inside it (our instruments), is currently not in the cleanroom. It will be back in 2016. It is currently in our cryovac chamber for testing.

About the Spacecraft Components

To learn more about the various components of the Webb Telescope, see the Observatory page as well as our interactive 3d spacecraft model (new window) (requires flash).

General Information:

You are looking at the largest clean room of its class in the world; it is located at NASA Goddard.These WebbCam views take you live into the NASA clean room where the Webb Telescope is being integrated and tested. Explore NASA Goddard's Cleanroom (new window).

Those who work in the cleanroom must dress in the outfits you see them in on the webcam (known unofficially as "bunny suits"). This is to ensure that any particles or contaminants on their persons are contained, in order to keep the room as clean as possible. The process of getting suited up is not trivial and the cleanroom workers often spend very long hours in the cleanroom without an easy way to leave for breaks. We on the project are very appreciative of the hard work they put into building and testing the hardware in such a challenging work environment.

Webb-cam Time-Lapse Movies

Be sure to check out our selection of time-lapse movies that compress hours and even days of Webb-cam footage into a few minutes.

Webbcam Usage:

The image is updated once per minute. The webcam pages and widgets update at the same rate to keep the latest image on screen. You can view the webcam on our Home page or on our webcam page at various sizes up to 1920px wide.

(There is always the possibility that the webcam may not function properly. Please bear with us if that is the case.)
