NASA Rover Finds 'Most Robust' Organic Carbon Signs on Mars
The rover mapped hundreds of carbon-rich signatures in two mudstones, adding the strongest evidence yet of preserved organic material in Jezero Crater.
- On Wednesday, NASA announced that the Perseverance rover detected complex organic carbon, known as macromolecular carbon, in two mudstones within the Bright Angel formation of Jezero Crater.
- Jezero Crater hosted a lake around 3.7 billion years ago, fed by rivers through an ancient delta; carbon is the primary building block for life on Earth, though its presence alone does not confirm biological activity.
- Using the SHERLOC instrument, researchers mapped hundreds of carbon-rich signatures in the Cheyava Falls formation, including distinctive "leopard spots" discovered in July 2024. Scientists caution the compounds could have formed through abiotic processes like meteorites or hydrothermal reactions.
- Co-Author Kyle Uckert noted this is the first detection of macromolecular carbon in mudstones outside Gale Crater, suggesting organics may have been widespread across Mars billions of years ago. However, the Trump administration deemed the Mars Sample Return mission "financially unsustainable," complicating Earth analysis plans.
- The Cheyava Falls sample ranks on the first step of NASA's seven-rung Confidence of Life Detection scale, though researchers emphasize further experiments are necessary. Scientists ultimately hope to bring these Martian samples back to Earth for definitive laboratory analysis of their origins.

NASA Rover Finds "Complex Organic Matter" on Mars
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 …
Perseverance rover finds even more signs of extinct life on Mars
Yet another Martian rock formation has revealed what may be signs of ancient life on the Red Planet. While these findings aren't as scientist-wowing as those reported last year, they add to growing evidence that ancient Mars contained organic carbon and may once have been habitable. An international team of scientists working on examining Martian rock samples collected and analyzed by the Perseverance rover reported in Science Advances Wednesday…
Researchers have discovered complex organic molecules in two rock samples on Mars. Is this the strongest evidence of prehistoric microbes so far?
Only laboratories on Earth will be able to draw a definitive conclusion. The Perseverance rover has discovered complex carbon molecules in rock samples on Mars. Scientists consider this a compelling argument in favor of the existence of life on the Red Planet in the past, according to RBC-Ukraine, citing The Guardian. According to John Bridges, a professor at the University of Leicester, the Jezero crater was clearly a suitable environment for p…
Did Nasa just find evidence of ancient life on Mars? Perseverance detects complex organic carbon
Nasa's latest Mars discovery brings us closer to finding alien life. Perseverance has found deep deposits of complex carbon compounds, strengthening the case for a once-habitable Red Planet
