Thanks for the update! Can’t wait to see the first images, I know it’s gonna be a while yet- like another five months or so…

It's going to be absolutely incredible, assuming everything works as planned.

The entire telescope is going to be only a few dozen degrees above absolute zero. They're cooling the main image sensors to 40° K by means of active refrigeration. That will permit observation at amazingly long infrared wavelengths, out to 28 microns. A military-grade FLIR camera with cooled optics goes out to about 14 microns at most.

28 microns is the peak wavelength emitted by a black body at 105°K, or -270°F. This corresponds to extremely old, red-shifted light.
