Well, they would be small. To get a rock all the way through the atmosphere to the surface (depending in part, of course, on the initial velocity of the object) requires something on the order of a large motor vehicle in size. I've only seen one "shooting star" in daylight, it was a nice (but brief, no more than three seconds) show. If one lies out under the stars, on any night, not even during the various annual showers, one will catch (usually in the corner of the eye) a shooting star every minute or so. They are very brief in transit, and typically they are no more than a tiny pebble or even a grain of sand. :')

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?

Why is it so credible that our atmosphere is bombarded continuously with small pebbles and grains of sand, (bits of rock and metal) but not small bits of ice? Frank’s theory (of small extraterrestrial ice bodies vaporizing in the upper atmosphere) seems perfectly plausible to me.
