[sci.crypt] spy satellites

Here is an extract from "Veil", by Bob Woodward:

page 30: "Another project [in 1980] was Indigo, a new highly secret
satellite system in development that could be the key to verifying
future arms control agreements with the Soviets. Using radar-imaging,
Indigo would see through clouds and work at night, when photographic
satellites were blind. This would be particularly important over
Eastern Europe, where the so-called 'demon cloud cover' could sit
for days or weeks."

Question: Is it possible to pick up human voices from space,
	  using satellites? I don't have the technical background
	  to judge such questions.

Thanks,

       -Tom
