Mars turned red from water-induced oxidation, not dry hematite rusting—rewriting planetary history.

New findings suggest Mars rusted while still wet, shifting timelines for its ancient lakes and rivers.

A Martian meteorite on Earth helped confirm that ferrihydrite, not hematite, tinted Mars red.

Scientists pulverized iron minerals to Martian dust size, proving ferrihydrite’s role in Mars’ color.

Mars’ red dust lacked signs of water, leading scientists to a false hematite theory for decades.

Ferrihydrite forms rapidly in cool water, implying Mars’ oxidation happened much earlier than believed.

Spacecraft data helped confirm ferrihydrite’s presence, altering our view of Mars’ wet history.

Mars didn’t just dry out—its signature rust formed in a way that preserves water’s ancient mark.

Future Mars samples will finally confirm how much ferrihydrite exists—and if life once thrived.
