Just barely less amazing. Still like finding one particular mosquito in Pittsburgh?
If the mosquito were two feet across and equipped with a radio transmitter, yeah.
No, Pittsburgh is a lot smaller than the reentry pattern of a falling satellite. By orders of magnitude. Thus the scaled comparison.
And I assume this was all necessary because:
(a) They wanted to see if it could be done.
or
(b) They couldn't yet build a digital camera and/or digital cameras didn't work in space because of some obscure issues with radiation?
It was 1960. No digital cameras. The CCD wouldn't be invented for nine more years!
