On the WebbCams Today

On our Webbcams are views of the assembly stand and the James Webb Space Telescope. The telescope is being assembled now. As of June 2016, the primary mirror (made of 18 hexagonal segments) is fully assembled, and the secondary and tertiary mirrors are also in place. The science instruments were installed in the telescope in May. We expect the telescope to be at Goddard approximately until the end of the calendar year 2016. There is additional installation work ongoing and there will be some testing on the telescope. After that it travels to NASA Johnson to undergo end-to-end cryogenic testing. You can read about upcoming milestones on our "What's Next" page.

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.)
