Historic Robotic Spacecraft Enamel Pin Set

We’re proposing a series of enameled pins based on five historic robotic spacecraft, inspired by posters we created in 2014–15. The featured missions were selected through a poll conducted by The Planetary Society, with the top five results being:  
  1. The Voyager Program  
  2. Cassini / Huygens  
  3. Mars Science Lab (Curiosity & Perseverance)  
  4. Mars Exploration Rovers (Spirit & Opportunity)  
  5. Sputnik
  6. You Choose via our poll!
As of now, only the *Voyager* enamel pin has been produced. While the rest of the missions already exist as part of our original poster series, they’ve not yet been translated into enamel pins—but they’re ready to go.
