- S46E12The Planets: Inner WorldsThe four planets closest to the sun, called the rocky planets, were born from the same material in the same era. But they couldn't be more different: Tiny Mercury is the runt of the litter, almost like a moon. Venus is devilishly hot, and Mars is a frozen desert world. Only on Earth do we find the unique conditions for life as we know it. But why only here? Were Earth's neighbors always so extreme? And is there somewhere else in the solar system life might flourish?
- S46E13The Planets: MarsThe Red Planet was once a vibrant blue water-world, home to raging rivers, active volcanoes, and even an ocean. But as the young planet's core cooled, its magnetic field and protective atmosphere faded, eventually exposing it to the wrath of the sun. With its volcanoes extinguished and its water lost to space, Mars became the frozen desert planet we know today. But if it once had many of the ingredients necessary to form life, how far along might that process have gotten?
