I expect so. Do you know if the instruments on these observation platforms are able to detect heat and/or visible light(or are these really the same things???) To the layman, it seems there would be additional evidence when/if hard objects are entering the atmosphere. But all I've been able to determine from these articles is that holes(shadows?) are frequently visible(on some wavelength) in the upper atmosphere. And these holes/shadows are NOT in the visible light range??? Is that about right?
FGS
I believe they would not be visible to the naked eye from the ground, but if they were, would appear to be a brighter spot. They show up dark in the part of the spectrum used by the satellites.
