Read the articles, you'll have fun, and I believe your question is addressed therein. I was 10yrs old when the first moon landing was on live tv. Classic - I remember Dick Nixon talking on the phone from the oval office to the moonwalkers. The Soviets did land a robotic probe on the moon, iirc, and the propaganda was heavy on both sides, and the media just as tightly controlled as it is now - we were at war in SE Asia after all, for some reason. Even if the Soviets outed us, I couldn't see it making it into the media over here. Haven't seen any review of Soviet media or position papers from the time.
