## Summary

In 1969, a fireball exploded over a tiny town in Australia, and the rocks that fell were hiding a secret about YOU. Grab your backpack and join Dr. PX on a space adventure to answer one big, weird question: are we aliens?

Four stops, one tiny superhero, and a twist at the end:
🪨 Space rocks carrying the building bricks of life
🛰️ The NASA spacecraft that grabbed a piece of an asteroid (like a claw machine… in outer space!)
🐻 The water bear that survived open space
🔴 The "leopard spots" a NASA rover found on Mars
⭐ And why every bit of you was cooked inside a star

### Murchison meteorite fell on a Sunday morning, 28 September 1969, near Murchison, Australia; a fireball broke apart and fragments fell over farmland

- [Wikipedia, "Murchison meteorite".](https://en.wikipedia.org/wiki/Murchison_meteorite)

### Amino acids found inside the Murchison rocks; some kinds are not used by living things on Earth, so they formed in space (v2 C03)

### Amino acids link up into proteins; muscles, hair and nails are made of proteins

- [Britannica, "Protein" (keratin in hair and nails; muscle proteins actin and myosin).](https://www.britannica.com/science/protein)

### OSIRIS-REx touched asteroid Bennu and collected dust; capsule parachuted into the Utah desert in 2023; samples opened in clean rooms; 14 of the 20 protein amino acids and all five nucleobases of DNA and RNA (v2 C05)

### Tardigrades (water bears): about the size of a grain of sand, eight legs; in 2007 thousands rode on the outside of a spacecraft (ESA FOTON-M3); no air, freezing, UV over 1,000× Earth's surface; some survived and had offspring (v2 C08)

### Perseverance found a rock with "leopard spots" (Cheyava Falls, 2024); on Earth such features are often made by microbes; NASA: potential sign of ancient life, not proof (v2 C11)
