The web cam is on a one hour delay. JWST is scheduled to reappear Saturday morning.

Good.  For a while it seemed like Blackstar was about to lose his mind because a multi-billion-dollar-science instrument stepped out of sight.  ;)

JWST is currently on its side.

Maybe they dropped it?

I think they're moving it to the other side of the room and unfolding it, and maybe they consider that sensitive for some reason.

Webb is back, and it is not in a thousand little pieces!

The view from the other camera, however...

purposefully out of focus camera or autofocus failure if these cameras are new enough to have that technology.

NASA's Webb Telescope Ghostly 'Lights Out' Inspection

What happens when the lights are turned out in the enormous clean room that currently houses NASA's James Webb Space Telescope? The technicians who are inspecting the telescope and its expansive golden mirrors look like ghostly wraiths in this image as they conduct a "lights out inspection" in the Spacecraft Systems Development and Integration Facility (SSDIF) at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

The clean room lights were turned off to inspect the telescope after it experienced vibration and acoustic testing. The contamination control engineer used a bright flashlight and special ultraviolet flashlights to inspect for contamination because it's easier to find in the dark.

NASA photographer Chris Gunn said "The people have a ghostly appearance because it's a long exposure." He left the camera's shutter open for a longer than normal time so the movement of the technicians appear as a blur. He also used a special light "painting" technique to light up the primary mirror.

The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. Webb is an international project led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

For more information about the Webb telescope visit: www.jwst.nasa.gov or www.nasa.gov/webb

So maybe that explains why the camera was down--they had the lights off during an inspection.

Working on a Saturday. Note the tower on the left with a guy on top. Obviously setting up some kind of instrumentation. I am guessing they will point that at the telescope.

They sure do move it around a lot.

In an earlier photo you could see that they had erected a stand off to the left with some instrument on it. I am guessing that this is intended to examine the mirror for dust. Probably measures reflectivity or something.

 I would have guessed an alignment check after all the vibrating and shaking. Do they do that somewhere else?
