Calling all space nerds: Orbit your next party wearing one of these sweet shirts and you are sure to encounter one or two heavenly bodies. Exploration requires the right attire.
Robotic and human missions of exploration that extended beyond the Earths orbit. 23 historic missions in total (with an additional 6 separations) that are recognized for their notable achievements to various celestial bodies in our solar system with targets including the Sun, planets and their moons, comets and asteroids. Nearly every icon represents a specific robotic explorer (or series) with the exception of the Apollo program which continues to be the single human endeavor to ever go beyond the cradle.
