On the WebbCams Today

WebbCam 1:

A crucial piece of flight hardware, the backplane (like the spine of the spacecraft), has arrived at NASA Goddard on August 25, 2015 from Northrop Grumman. Here are some of the things you might see on camera. For a few days you may see the giant white packing case for the backplane, currently to the left of camera. The shiny half-cylinder is the inner cover of the packing case. In the back of the cleanroom in a metallic latticed structure is our flight instrument module. The flight backplane is on a rotating stand currently.

WebbCam 2:

A view of the assembly stand where JWST's mirrors will be mounted onto the backplane structure that holds them. The flight backplane is on a rotating stand currently. View images of the flight backplane at NASA Goddard.

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).

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.

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.

Webbcam Usage:

The image is updated once per minute. You can view the webcam on our Home page or at a slightly larger size on our WebbCam page.
