Have we been wrong about why Mars is red? 🔴

For years, scientists believed Mars got its red color from hematite, a type of rust that forms in dry conditions. But a new study suggests something surprising—ferrihydrite, a different kind of rust that forms in cool liquid water!

This discovery could mean Mars was once much wetter than we thought—maybe even habitable. And the best part? Our Rosalind Franklin rover will soon analyse Martian soil up close to uncover even more secrets.
