James Webb's telescope is encountering space trash in... an orbit. Any L2 halo is, yes, an orbit (if not a stable orbit). About which NASA were warned.
h/t Will Gater who is delivering toljaso on Twitter; also Zim. The mirrors present the greatest surface-area to space pebble, and indeed a mirror is what has taken this particular (heh) shot.
This one was a "micro" meteor. I suppose the other three were nano'. Hate to see what milli' will look like.
I don't know how we shield this. NASA's calculations were "so much impact in as much time as we have so much propellant".
