Hosts Robert Lamb and Joe McCormick explore the challenges of reaching Mercury, detailing how spacecraft like MESSENGER and BepiColombo use gravity assists to counteract the Sun’s gravitational pull. They examine the planet’s unique geology, specifically the Pantheon Fosse, and discuss theoretical past habitability in polar craters. The episode concludes by tracing Mercury’s portrayal in science fiction, from early tales of surface life to modern visions of harsh, subterranean mining colonies.
