#69 NASA Scientist Reveals What We Really Found on Mars!

Dr. Amy Williams is a NASA geobiologist and astrobiologist searching for one of the biggest answers in human history — are we alone in the universe?

As part of the Curiosity and Perseverance rover teams, Amy helped uncover the largest organic molecules ever found on Mars — long-chain alkanes up to 12 carbons long, potentially fragments of ancient fatty acids, the same molecular building blocks that make up living cells on Earth.

Her work on NASA’s Sample Analysis at Mars instrument and upcoming Mars Sample Return mission could soon bring those ancient Martian molecules back to Earth — offering humanity its first real chance to detect extraterrestrial life.

Expect to learn how scientists distinguish living from non-living chemistry on other planets, what these discoveries mean for the origin of life on Earth, why Mars may once have been a twin of our planet, how life might survive deep underground today, and how finding life beyond Earth could transform our understanding of who we are.
