Greatest Discoveries This series is based on the greatest outer space discoveries to occur over the last 10 years. I gave the designs a 1950's and 60's feel by adding static to all 6 designs and adding a glow to the letters like an old school television. I wanted the 50's and 60's feel because during that time space exploration was at it's peak. Between sending satellites to space and landing on the moon for the very first time in history. We are finally at a time where space exploration is a top priority.
