Even for the rest of us, the giant machines that travel through space are fascinating if we stop to think about it. There is a certain thrill in knowing that some craft has been propelled beyond the confines of our planet. For the last 70 or so years, we've shot many machines into the vast and final frontier, carrying scientific instruments, Earth-observing satellites, and extraordinary men and women to inspect, explore, and redefine our world and the universe beyond.
Most of these machines never return home. But those that do come back always find their way to a museum to be a source of amazement and inspiration for the public.
