Why Sloths Are Perfect Astronauts

Captain Sergio, an astronaut sloth, introduces Hang Time—a podcast exploring the cosmos at a pace that actually lets us appreciate how mind-bending it all is. In this inaugural episode, Sergio shares his origin story: from dreaming under the stars in Costa Rica’s rainforests to training at NASA, and finally to his first mission on the International Space Station. He argues that sloths aren’t poorly suited for space exploration—they’re perfectly suited, because space itself operates on slow timescales that reward patience and careful thinking.
