The Most Important Rock In History Is Stuck In A Locker On Mars

The Most Important Rock In History Is Stuck In A Locker On Mars

We interrupt your regularly scheduled debunking of ancient astronaut theories for an emergency broadcast: We might have actually found aliens this time. No, really.

Scott and Tristan break down the discovery of the Cheyava Falls rock by the Perseverance rover. This dusty red doorstop features "leopard spots," which, on Earth, are a chemically specific signature of biological life. We discuss the rigorous science behind the "COLD" scale (Confidence of Life Detection), why this rock might be the most important thing ever drilled, and the agonizing reality that it is currently stuck millions of kilometres away because the Mars Sample Return mission is wildly over budget.

Then, to make sure you don't leave this episode feeling too hopeful, Tristan explains why finding independent microbial life on Mars might actually confirm that the "Great Filter" is ahead of us, and that we are all doomed.
