Why has Mars held our imagination captive for over a century? Journalist and best-selling author David Baron joins hosts Cady Coleman and ASU Professor Andrew Maynard to dig into the wild, true history of our obsession with the Red Planet. From Percival Lowell’s canals to Tesla’s radio signals and Alexander Graham Bell’s firm belief in Martians, it’s a tale of science, belief—and mass delusion.

Featuring David’s new book, The Martians, which uncovers how the world once truly believed Mars was inhabited—and how that belief gave rise to science fiction and the space age.

The first humans on Mars will need more than bravery—they’ll need teamwork, science, and systems built to last.
