On July 20, 1969, astronauts Neil Armstrong and Edwin “Buzz” Aldrin left humanity’s first footprints on the Moon. Along with bootprints, they left a plaque: “Here men from the planet Earth first set foot upon the Moon, July 1969, A. D. We came in peace for all mankind.” While this endeavor was driven by a Cold War between the United States and the Soviet Union, its impact was felt around the world. For All Humankind collects the memories of eight non-Americans touched by this historic event to convey how this mission was, indeed, for all humankind.
