Red Planet Mars.

American astronomer obtains images of Mars suggesting large-scale environmental changes are occurring at a pace that can only be accomplished by intelligent beings with advanced technology. At the same time a colleague claims to have been contacting Mars by radio, using technology stolen from the Nazis after World War II. The transmissions claim that Mars is a utopia, which has led to great technological advancement and the elimination of scarcity, but that there is no fear of nuclear war. The U.S. government imposes a news blackout and orders the transmissions to stop due to fears that the Soviet Union could pick up their messages.
