The government employees of NASA (The National Aeronautics and Space Administration) have the astonishing task of space exploration and research, in aeronautics and aerospace. They are a civilian agency that serves as an independent executive branch of the federal government. Any employee of NASA's team has earned the right to carry this challenge coin from scientist, researchers, engineers, technicians and planners to the janitor. They all play a key role in shaping not only the future of American space exploration but all of humanities. NASA's members should be proud to serve in an organization that won the space race to the Moon, helped build the International Space Station, can see deep into the heavens with the Hubble Telescope, explored Mars with the Curiosity Rover, and flew past Pluto with the New Horizons space probe. There are many other noble achievements and advances in science and technology that go unseen to the public. This challenge coin is dedicated to all NASA personnel, whose service and sacrifices strengthens America. Minted in brass, this custom coin contains colorful enamel accents, is antique silver plated and is 1.75” wide.
