NASA's Curiosity rover found pure sulfur crystals in an ancient Martian riverbed, challenging current geological theories.
In May 2024, NASA’s Curiosity rover accidentally cracked a rock in Mars’s Gediz Vallis channel, revealing yellow crystals of pure elemental sulfur—never before seen on the planet.
The discovery, surprising to scientists, challenges existing models of Martian geology, as elemental sulfur typically forms under specific conditions not yet understood.
Found in an ancient riverbed, the sulfur may indicate past aqueous activity and unknown chemical processes.
The find highlights the role of serendipity in exploration, as the sulfur was hidden until the rock was fractured.
Curiosity continues collecting samples, while Perseverance advances across Mars, searching for signs of past life.
