Very good. Yes. The LHC (Large Hadron Collider) at CERN is a microscope that's more than five miles across.
In fact, however, and if I read this announcement right, SPIDER is a way to make telescopes very large indeed, by "virtualizing" their optical aperture. This opens the door to amazing possibilities.
Also frightening possibilities.
Note that in the "How SPIDER sees" image from Lockheed upthread, SPIDER is "looking" down at us, rather than out into space.
If needed to stop it all that’s needed is a man to operate a high tech rolled up newspaper or bedroom slipper.
