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.

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
On Mars there are conditions that actually make organic material impossible. And yet the NASA Rover "Perseverance" has found something there.
The rover Perseverance has identified organic carbon molecules in the rocks of a riverbed carrying water billions of years ago, which could come from biological sources or biological processes, unrelated to life tests The race to collect extraterrestrial material opens a dilemma about where to store it safely: is the Moon a good place? NASA's rover Perseverance has detected complex carbon molecules in Martian rocks that have aroused the attentio…
