Dr. Goddard was the first modern scientist to have a vision for space travel and also the ingenuity to formulate solutions to rocket propulsion. He was the first to make mathematical calculations that showed how rocket propulsion could be used to travel to the moon. Handcast in solid, lead-free pewter each of our pins is an original three dimensional sculpture signed by the artist, Jim Clift. Individually packaged on one of our signature presentation cards, our pins are ready for gift giving. Show someone the moons the limits with our rocket lapel pin!
