NASA IS BREAKING A CARDINAL RULE OF BRANDING

Summary from the TLDR Design newsletter

NASA has been using both its "worm" and "meatball" logos simultaneously as it enters its Artemis era. The meatball logo is the official one, while the worm logo, which was used from 1975 to 1992, serves as a supporting element. Design experts and NASA officials agree that both logos have their place and complement each other, representing the agency's heritage and modernity, respectively.
