Researchers analyzing data from NASA’s Curiosity rover have determined that the non-biological processes examined do not fully account for the presence of organic compounds detected in a Martian rock sample. In March 2025, Curiosity’s onboard chemistry lab identified small amounts of hydrocarbons including decane, undecane, and dodecane.
The study explored various abiotic mechanisms that might produce these organics but concluded that these sources alone cannot explain the observed abundance and variety. This suggests that other processes, potentially including biological activity, may need to be considered to understand the origin of these compounds on Mars.
**Why this matters**
Organic molecules are key indicators in the search for past or present life beyond Earth. Understanding whether these compounds arise from non-living chemical reactions or biological sources is crucial for interpreting Mars’ habitability and the planet’s potential to support life. This research highlights the complexity of Mars’ chemistry and the need for further investigation.
