Episode notes
Venus Is Earth's More Relevant Twin
- Venus is closer to Earth and similar in size, making it a more relevant comparison for Earth's evolution than Mars.
- Studying Venus helps reveal planetary heat loss and tectonic behavior relevant to Earth's past and future.
Tectonics Versus Plate Tectonics
- Venus has tectonics but not Earth-style plate tectonics, so it cools differently than Earth.
- Comparing Venus's tectonic style reveals why Earth's plate tectonics are special and when they might emerge.
Tessera Preserve Venus's Baby Book
- Tessera terrains are the oldest coherent rock records on Venus and argue against past plate tectonics.
- Their preserved global patterns imply Venus never recycled surface lithosphere like Earth.
