It wouldn’t surprise me if CIA DID have such an instrument. I think that the focal length would have to be much shorter however, to image the Earth’s surface. Hubble’s primary mirror is at f/24. It is claimed that Hubble can’t image the Moon’s surface to show us the Apollo landing sites because the Moon is too close. That’s my understanding.
Here is an image of Copernicus Crater, imaged with HST:
Link HERE for an article describing how the images were captured.
Very important information from the article:
A close-up view of Copernicus' terraced walls. Hubble can resolve features as small as 280 feet across.
Lunar landers, rovers, tracks, and footprints are all much smaller than 280 feet.
