A long-standing tradition within NASA and JPL is the release of commemorative enamel pins. Events such as launches, landings, milestones, and mission anniversaries are cause for the design and limited distribution of these pins among employees. Adorned with imagery that represents the missions they celebrate, these enamel pins have become collectables among JPLers and space enthusiasts alike. They serve as commemorative tokens for historic moments and form a timeline of JPL/NASA’s accomplishments throughout the years.
