Mars's Hidden Rivers: Hydrogen, Mega Basins, and the Quest for Ancient Life

Join us as we connect climate and chemistry models to Mars' faint young Sun paradox, where crustal hydrogen release and episodic volcanism could have produced bursts of warmth long enough for rivers to carve vast networks. A new map identifies 16 mega basins—each over 100,000 square kilometers—that cover only about 5% of the ancient terrain but contain roughly 42% of the river-eroded sediment, concentrating Mars' chemical history. With Perseverance findings like kalinite in Jezero and iron-phosphate-rich specks in Sapphire Canyon, these hotspots become the most promising targets in the search for signs of past life and a precise roadmap for future missions.
