Also on the scientific front, Voyager 2 has discovered a dent in our solar system due to magnetic forces.
Voyager 2 finds solar system's shape is 'dented'
I was 10 years old when the Voyager probes were launched, along with their Golden Records. An excerpt from the Voyager 1 greeting by Jimmy Carter (given in the Wikipedia article) goes like this:
We cast this message into the cosmos… Of the 200 billion stars in the Milky Way galaxy, some — perhaps many — may have inhabited planets and space faring civilizations. If one such civilization intercepts Voyager and can understand these recorded contents, here is our message: We are trying to survive our time so we may live into yours. We hope some day, having solved the problems we face, to join a community of Galactic Civilizations. This record represents our hope and our determination and our goodwill in a vast and awesome universe.
The 70s were in some ways a very hopeful time, weren't they?
