NASA (Jet Propulsion Lab) have released 14 stunning, retro-inspired space travel posters which take us on a futuristic trip around our solar system and beyond.
Each poster tells a story of a different celestial object and its unique astrological features.
These posters were actually kept by NASA and intended for internal use, but now they’re free to download in high-res:
