In this Radiolab podcast episode, astronaut Dave Wolf shares his thrilling spacewalk experiences. He paints a vivid picture of the stark contrast between the intense brightness of sunrise in space and the pitch-black shadows of Earth, where darkness feels so deep that it seems to swallow his arm. Wolf recounts a terrifying moment when he found himself locked outside the Mir space station due to a malfunctioning airlock, facing the terrifying risks of CO2 poisoning and even the possibility of boiling inside his suit. The episode concludes with a serene, almost spiritual moment of quiet reflection among the stars, emphasizing the profound emotional journey that comes with space travel.
