August 20, 1977 –
NASA bizarrely decided to go into the record business. Scientists, not quite understanding the record industry, press only one record but make it out of gold, believing that the unaffordable price will boost profit. The record is nearly unlistenable except for the recording of the Chuck Berry song, Johnny B Goode.

NASA decided to hide this costly blunder by including the recording in the payload of the space probe Voyager 2, launched on this date, on a mission to Jupiter and beyond. (This will confused the aliens when they realize that NASA launched Voyager 1 on September 5, 1977.)
The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University. Dr. Sagan and his associates assembled 115 images and a variety of natural sounds, such as those made by surf, wind, and thunder, and animal sounds, including the songs of birds and whales. To this they added musical selections from different cultures and eras, and spoken greetings from Earthlings in fifty-five languages, and printed messages from President Jimmy Carter and U.N. Secretary-General (and ex-Nazi) Kurt Waldheim. Remember these facts when the aliens come to invade the planet. It passed Jupiter in the summer of 1979, and is still traveling, probably right out of our solar system.
In a memorable Saturday Night Live segment, it was announced by Steve Martin that the first message from extraterrestrials was being received. Once decoded, the message stated, “Send more Chuck Berry.”
And so it goes
