New Research Reveals Water-Rich Mineral May Explain Mars' Red Color

Mars' red color comes from ferrihydrite, an iron oxide that forms with water, challenging previous beliefs it was due to hematite.
The study, published in Nature Communications, indicates Mars had wet conditions in its early history, contradicting the notion of a completely dry planet.
The presence of ferrihydrite suggests conditions required for water and oxygen interaction with iron.
NASA emphasized the study's implications for understanding Mars' potentially habitable past and the need for continued research on the planet.
