Cheyava Falls Mineral Map — Perseverance PIXL

This mineral map was produced by NASA's Perseverance rover using its Planetary Instrument for X-ray Lithochemistry (PIXL) while studying the Martian rock known as Cheyava Falls. The colored overlay highlights the distribution of two minerals—vivianite and greigite—across the rock's surface at microscopic scale.

The mineral pattern forms part of the rover's investigation into possible ancient biosignatures. Although these minerals may be associated with biological processes on Earth, NASA emphasizes that non-biological explanations remain possible. The image represents one of the most detailed geochemical maps ever produced on another planet.
