Re: Space shuttle was photographed by Keyhole spy satellite
The history of the Shuttle with the description of KH sat squared photography was probably "Into The Black"
Similar imagery was taken of Skylab, which allowed NASA to appropriately tool and equip the Skylab 2 rescus mission. I don't recall where I read that..
There was ground based IR photography of Columbia's last re-entry which was released in a very blocky, pixelated form showing that the shuttle was damaged and no longer symmetrical. The original imagery was no doubt better, but not de-classfiable.
