Watch the Webb In Progress on our "Webb-cam"!

We now have two webcams in the Building 29 cleanroom at Goddard, one showing the left side and one showing the right. The camera images below are updated every minute. The cleanroom is generally occupied from 8:00am to 4:30pm Eastern, Monday - Friday. There may not be much activity outside of these hours.

The cleanroom is always changing so you may not see the same thing every time. The large structure taking up the right side of the clean room is the Ambient Optical Assembly Stand (AOAS), which will be used to assemble the mirrors and instruments of the James Webb Space Telescope.

This black latticed structure is the "spine" of the telescope and will support the mirrors as well as the instrument module. It has three long booms which extend outwards to hold the telescope's round secondary mirror. Two spare hexagonal primary mirror segments, as well as a spare secondary, are being installed onto the pathfinder via a robot arm. Afterwards, the whole structure will go to NASA Johnson for cryogenic testing.
