NASA, Intercepted pairs randomized strings of NASA acronyms with clips from an onboard recording of Apollo 8, whose three astronauts captured the first color photograph of Earth from outer space on December 24, 1968. Known as Earthrise, this iconic photograph transformed our relationship to the planet and helped catalyze the environmental movement. According to a NASA publication, the “eyewitness accounts [of the Apollo 8 astronauts] impressed millions of men with the true reality of our situations: the oneness of mankind on this island Earth, as it floats eternally in the silent sea of space.” Or as NASA chief Thomas Paine told Look magazine, their photographs “emphasize the unity of the Earth and the artificialities of political boundaries.”
