NASA Rover Finds “Complex Organic Matter” on Mars
A "resounding win for Mars science."

After more than five years of roaming the desolate and dusty landscapes of the Martian surface, NASA’s Perseverance rover has come across some of the most intriguing evidence yet of ancient microbial life on the Red Planet. As detailed in a new paper published in the journal Science Advances, scientists confirmed that Perseverance had discovered a rock that contained “complex organic matter” — the building blocks of life, in biological parlance — in two rocks in a formation dubbed Bright Angel.
The outcropping is located inside the Jezero crater, which scientists believe is an ancient lakebed that dried out billions of years ago. The scientists found that samples from the rocks that Perseverance originally found in 2024 contained macromolecular carbon (MMC), large networks of carbon atoms commonly found in Earth rocks containing fossilized biological carbon and meteorites.
An initial analysis of the rocks made headlines last year after NASA announced it had spotted “potential biosignatures,” pointing at compelling “leopard spots” that may have been left behind by microbial life.
The latest paper fleshes out the compelling case even further, confirming the detection of MMC in the rocks by using one of Perseverance’s scientific instruments to detect their composition by shining an ultraviolet laser at them.
