Questions About This Episode

What is An Ancient Moon of Mars? about?

The story behind this investigation is almost more cool than the discovery itself. Microlayers of sediments in Mars' Gale Crater, observed by NASA's Curiosity rover, are indicative of tidal sloshing of water in the lake that once filled the crater. Problem is, the age of the rocks and the magnitude of the tides would require a different moon than the ones currently there. Cool! Join us to hear about that, interstellar comet 3I/Atlas, and much more.
